Hi mad modders I have started a new project and thought I would share it.
I found a book titled Motor Bicycle Building by Paul N. Hasluck. It shows you how to build a complete motor bike with 2 different engines. I am building the larger one with lots of changes to suit me. You are supposed to make castings for many of the parts. I will use weldments. If you try to buy this book be careful I bought the one with the flower on the cover and it has no drawings in it. :doh: you can get the book free off the internet. I have made quite a bit of progress on the engine and will get you caught up to where I am. Tom
thank you Eric for the help.
I started with the crank shaft, its made up of the 2 flywheels, crank pin, and main journals.

Wow oh wow Tom!!
This is my kinda thing. I will be watching this anxiously... now to find that book!
Eric
**Edit
Found it! HERE (http://archive.org/details/motorbicyclebuil00hasliala)

Thanks Eric for posting that link.
Here are some pictures of how the crankcase was made. This engine will be rough built to check the fit of parts then disassembled and fine tuned. Are these pictures to big?

Great work :thumbup:
The pics are a touch big.
Just read the book through very good read, its got me thinking if it could be scaled down to say 1/3, I'll be watching progress with great interest.
Stew
-
Wow, that is a really nice crank case. Very nice. It still looks like period item.
One question: Why the nuts on crank shaft? Are pins shrink fit? Does original design asks for nuts?
Pekka
-
No criticism as you are following the book but I notice the absence of balance weights on the flywheel ?
-
Oh, My...... This is going to be a cracker! :bugeye:
Thanks for posting, Tom. :thumbup:
I'll watch quietly. Won't be any trouble. :)

Thanks guys I am working on the picture size but photobucket seams to be having a problem.
John I am not familiar with bike engines. The crank is what was in the book and the book was printed in 1906 maybe the author didn't know about balancing or the engine ran so slow it didn't matter. I plain on drilling some holes on the heave side to balance it. I think I read some where about adding half the rod weight to the crankpin first?
Pekka the pins are tapered 3 degrees the nut holds them in. Original design
Stew I believe you could scale it to whatever size you like please post it if you do.
Here are some more pictures of the crankcases I welded the main bearing bosses in and line bored them. Made some main bearings and pressed them in. bored the hole for the cylinder and drilled and taped the cylinder mounting holes. Tom

I like what I see Tom :bow: :bow: :bow:, looks spot on , I will be watching with interest, Keep up the good work :thumbup: :clap: :clap:
Cheers Mick

Tom.
Really really nice work, like the hollow dowel to locate the cases.
Balancing involves adding metal opposite to the load ie, piston and rod or removing metal close to the load.
So in your case it would mean drilling holes to either side of the crank pin.
Here's a nice book to help on a lot of design issues.
http://www.stevenson-engineers.co.uk/files/TuningForSpeedByPhilIrving.pdf
Page 96 covers balancing.
But I would like to say I'm not trying to nit pick on Tom's build which I have to admit is nothing short of brilliant
-
Pretty cool :thumbup:
Are the casing halves dowelled together? Will you line-bore the main journals together with the casing halves joined?
I love how welding porosity looks just like casting blemishes :D
-
I've seen several similar builds, over the years.
I love to see how quality plating and welding work comes together, to produce "castings"...... :clap: :clap:
David D
-
Thats going to be a nice looking engine.
Funny enough I was only talking to Jo over on MEM the other day about making a similar style crankcase but to use a Hoglet as the remainder of the engine rather than using teh open crank design.
This may give you some inspiration http://flashbackfab.com/excelsior-project-paul-brodie/
-
John,
Thanks for that link.
Irving's book was 'the Bible' when I was a teenager trying to get my old Royal Enfield Model G (1948) to at least complete a trip without stopping.
I lost the book when my parents moved house whilst I was in the army. Now I at least have a PDF.
Dave. :D
-
Thanks guys
Pete one of the first things I did after welding the cases was install hollow dowel pins. you can see them in some of the pictures. The cases were bolted together and put in a four jaw chuck. Then the main bearing journals were bored.
John thanks for posting that book its going to be a big help. I was surprised to see the connecting rod in that book was made from parts welded together.
Next up is the cylinder. At this point I am leaving the original design. I bought a box of sleeves at a flea market and when I got home I looked in the boxes some of them came with liner, piston, pin, and rings. The one I am using is 3.25 bore. this and a stroke of 3.75 should give me a little over 500cc :scratch: notice the 4 ring piston and dome on top. The cylinder was turned from a piece of dom tube 5' od 3' id bored and the sleeve pressed in. tom

Yeah I see the dowels - right in plain view - now. Dunno how I missed those :)
-
Great project. Are you also planning to fabricate the frame for it?
-
What size tube or pipe did you use for the crank case please?
-
Andyf.
Sent you a PM so as not to get OT
-
Hi guys
SMP the tube is 9 inch od 1/4 wall.
Pete yes the whole bike.
Here is how the connecting rod was made. The pin holes were left under size until after welding.

Hi Tom,
That is a real case of :proj: :bow: :jaw:
I will be watching progress, especially as it looks similar to a bike that my great grandfather won a grass track race on at about the same time (he went on to build two racing Douglases, 'Otterzell' and then 'Otterstill' in the 1920's)
Eric and John, thank you so much for the books.
Andy

Hi guys.
I have been working on the cylinder head and the timing gears. This engine has a lot of crankcase presser on the down stroke and needs a case vent but the book said to just buy one. I would like to build a period correct one and am not sure where to put it. Have you got ideas on how to build this and where to install it. thanks Tom
Here you can see the bosses installed in the case.
(http://i1323.photobucket.com/albums/u592/Toms1909engine/IMG_0946_zps8d06215e.jpg)
The cylinder head still needs the fins cut and the intake and exhaust flanges installed.
(http://i1323.photobucket.com/albums/u592/Toms1909engine/IMG_0949_zps3cd4b4fb.jpg)
-
Tom,
Can you vent it into the timing case thru a hollow mainshaft and time it with a cross hole that opens into the timing side mainshaft bush on the down stroke.
Some early Brit engines vented into the Primary chaincase to lube the chain.
John S.
-
John it sounds like a good idea to vent it into the timing gear case to lube the gears but it is also a sealed compartment . I take it that the vent should be a one way valve only venting on the down stroke? thank Tom
-
Tom, you time it by using a cross drilled hole in the main shaft that lines up with a groove in the bush so the hole only lines up with the groove on the down stroke.
You could always fit a labyrinth breather in the timing cover.
-
John thanks for the info.
I got some more done on the timing gears. Built a cam box and side plate.

-
Looking the biz.
Do the cams go behind the gears ?
-
Yes John the cams go behind the gears it will keep the box narrower. The main shaft boss puts the drive gear out to far.
John I found this picture below on the net. I think its Norton. The lifters are not placed over the center of the cam shaft is this a good design ?
(http://i1323.photobucket.com/albums/u592/Toms1909engine/norton1_zps50bcb076.png)
-
I wonder if those lifters (cam followers) are original. Having the sharp edge of them contact with the cam doesn't look very professional. I would expect severe wear of the cam.
Dave. :scratch:
-
Tom.
That picture doesn't look right, all the followers I have seen have been top hatted at the bottom.
They are usual off set along the line of the crank where they sit on the cam so the cam first touches on one side and wipes the follower round. This is to equalise wear.
I'll see if I can find a picture.
EDIT Could be right, found this image
http://www.nsamotorcycles.co.uk/ekmps/shops/nsamotorcycles/images/norton-16h-tappet-rod-guide-assembley-complete-1125-p.jpg
-
This may be a daft suggestion but could there be something missing from the picture - eg finger type followers pivoted at the corners of the case and lifting the rods.
Russell
-
I think Russell might be correct as there are two unused bushes right where a finger or slipper would be needed
-
Thanks guys
I think Russell is right I missed that.
-
Wonderful work, and great subject! :clap:
(I saw the turkeys in the photo -- does the TomT relate to that?)
-
Some early Brit engines vented into the Primary chaincase to lube the chain.
John S.
And later ones just lubricated the driveway...
bob

Looking really nice.
Yes, as John mentioned, a lot of early motors had a Breather gear that was timed. Harley Davidson used the pretty much the same engine case setup and timed breather setup from 1936 all the way up to the 90's (if you can believe it). ...and almost all earlier models were pretty much the same too.
To give you an idea, the breather was a hollow cylinder about 3" long and 1" in dia and had a solid gear on the gear case side (driven by the cam) (Open end of breather cyl faced into crank case). It had a window on the side that lined up with a window in the gear case side when in time. The Breather slid into the case connecting to a pocket in the back of the crank case. When venting, the windows would align venting crank case pressure into the breather (inside the hollow cylinder) and out into the gear case. And then from a fitting/tube into the Primary chain side to mist oil the chain.
I am sure I made it sound more complicated than it is, but you could certainly dumb it down for your needs. I am sure I could come up with some pictures if you need.
Regards,
Shawn
-
Most of my Harley pictures are pre digital camera :palm:, but I quickly dug some up on the web to illustrate.
Notice the breather annulus? And the casting behind it on the left that serves the pocket in the crank case.

and the breather gear

Timed with cam
(http://www.nightrider.com/biketech/images/cam_install_05.jpg)
-
After some thought, I realized that you are probably looking for something more period correct (which I am not sure if this is or not). This type of design "I know" was in some of the 20's era, but I have no experience on motorcycle engine dating prior to that.
Very interested in seeing what was used though...
-
I think this shows what RusselT was talking about
-
Now that makes a lot more sense.
Dave.
-
What engine is that please ?
-
Looks a bit like a Norton SV to me.
Big 4-ish ... ???
Although probably wrong, I usually am ... :scratch:
Dave BC
-
What engine is that please ?
Not sure of the model. It's pre 1931 as it has exposed pushrods. More info at http://vintagenorton.com

Thanks for the info. guys.

I just had to bolt it all together to see what it looked like WOW not bad I started this project 59 days ago. I still need to add the intake and exhaust flanges to the head. Now its time to take it apart and finalize the parts,install the mag.and figure out what to do for a carburetor.

You would have done it in less than 59 days if you hadn't drunk all that beer :headbang:
Any shots of the inside timing case now it's finished ? The finning on the head looks stunning.
-
Thats looking great, cant wait to hear it running. Ive enjoyed reading this thread loved the total fabrication concept.
John
-
Excellent job. Looks great!
-
Hi guys
In order to finish this engine I need to mount it in the frame so I will know where to mount the mag. and carb. so I have started on the rest of the bike. Here is a picture of the front half. I built everything in this picture accept the tire and the hardware. some changes will be made to it as this build continues. Tom

Wow, that sure is appealing. And I'm not even into motorcycles. But that would sure convince me. :bow: :beer:
-
Tom, is the frame, suspension and wheels all based on the book you referenced earlier in this thread? I've been planning something similar with an existing engine and I really like what the looks of this setup.
-
Hi
Tom
I have just been through the whole post :bow: :bow: :bow: :bow: :bow: :bow:
Some very nice (& clever ) work there
I think it will sound amazing
John
-
It is an excellent project and well produced, thank you and keep it coming please !
Well John i'm pretty sure that between a few of us we could all make one each then link them to form a V8 or a W16 or whatever number we ended up with ? ( an in-line 13 ? ) :Doh:

Thanks for the input guys.
rschilp The frame I built was not in the book. I built it form looking at pictures of old 1915 Indian motorbikes. The wheels are my own design. Here is a picture of them.

-
The only question I have, Tom, is, with the engine that tall and heavy at the top, is there enough side to side support on the one tube frame members? Like if you lay it down, will the engine want to deflect sideways. I do see the nice double gusseted bracket supporting the engine case, but above that where the frame is a tube there will be some pretty good local twisting strains, maybe?.
Of course you can tell better by feel, since you have the bike and aren't just looking at a photo, like I am. Also I don't know how heavy that tube wall is or if there are doublers, etc.
-
Yabut simple job to drop a head steady on it.
-
John is right I will add a head steady . but I am not sure it needs it . I ordered .120 wall tube for this bike and after I built the frame I ordered some more for the handle bars. when it showed up I discovered that the first batch was .160 wall. :doh:

Tom, thank you for those drawings, I assume those provided some of your inspiration.
At .160 wall you should have a very sturdy frame ;-)

@ OKTomT
Just joined this forum because of my intense interest with this engine build. I have so many questions, and I want to scratch-build a full-size, vintage bike engine like the one pictured in this construction article.
While your photo-build is wonderfully informative, of course few dimensions are noted concerning the engine, like con-rod lengths, gear specs. etc. Is this an engine that you designed or can this be an engine from some book on how to build a vintage bike like Hasluck's "Motor Cycle Building-1906"? I really need some more critical dimensions to duplicate the engine...I'm not as good as you are and need a detailed road map to Engineland.
Following this build with very great interest, and greater anticipation. Thanks for sharing.
Frank
EDIT: Sorry...Just re-read the opening postings and realized that the bike and engine designs are taken from the Hasluck's book. So excited about finding this thread that I skipped over the important details of the engine-build. Now to hunt down the book. Anyone know who retails the book? Lindsay's gone.

Mr. Chips...
Thank you for the link-up.
**************************************************************************************************************
@ OKTomT: Crankcase is split construction, and two halves are bolted together. How do you prevent oil leakage from seams? Gaskets, sealants? Just curious.
Frank
-
Frank did you read the second post? the book is available online so no need to buy.
J

JasonB...
My eyes glazed over when I saw the engine being built, and they stayed glued to the photos. There are times when I think I am losing it...and I get tunnel-vision. Certain engines do this to me, and my brain edits everything out that's around me. I even started collecting scrap for making this engine. I'd say that's jumping the gun.
Now...I'll take a deep breath, and go back, and this time, carefully read all the words, etc.
Thank-you for letting me know that this book is available online. I'll give a look. Much obliged.
Frank
EDIT: Just found this text book on the on-line library link. I just saved approx. $20.00 USD I will try to copy only the engine building instructions etc. It's Christmas, again!
-
I spent the last few hours reading the book. The engine design presented here is considerably different in some areas, like the head, valves, etc, than the engine described in the book Honestly, I think this modern engine is built much nicer. The above engine is fabricated from bar-stock and weldments. That's the good part. Ruin a part...go to the scrapyard for replacement materials.
My dilemma: What steel(s) do I use for the con-rod? I would speculate that any steel that's available today has to be better than the steels of 1906. What about valves, rocker-arms, bearings, cam followers, camshaft ... etc? What should be hardened, case-hardened, etc. Do rules for material selection for model engine parts translate to full-size, working engines?
I guess this is a British publication, using British terms for some parts, like gudgeon pins, "tommy holes", (whatever they are).... etc. Stay tuned, I may need some translations. What is a "tommy hole"?
I hope this engine/bike build continues to the end.
TomT...you got my full attention....

I am very glad that a link was provided that leads to the text copy of the Hasluck book. My interests are in building the engine only, and not the bike.
Regarding the engine-fabrication section of the book:
The book goes into great detail about how to machine the commercially available, 1906 castings for this engine. The majority of the text is written for the times, the terminology is difficult to understand, and, is mostly archaic. Our modern tools, and machining methods would be used instead of the methods used back then.
If you are going to build this engine from bar-stock and weldments, about 75% of the written text is useless, and has nothing to do with the engine that is being built in this thread. Granted, the engine in this thread is derived from the textbook design, and some of the parts and measurements may be the same, or, very similar, but the modern version just "looks" old-fashioned.
I am very glad that I did not have to order the book and then be ultimately disappointed after reading the engine chapter. By the way, there is a smaller, and lighter version of this engine-type in later chapters. The directions will give you and engine with a 2-1/2" bore and stroke.
If it's the modern version of the engine that you want to build, follow this thread closely. The book will not fill in the blanks....unless you want to wind your own spark-coil, and make a spark plug. I'd rather go to the store and buy them...but hey, that's just me. I'll follow Tom's way.
Just my opinion.
Frank
-
Frank you do need to bear in mind that amoung the membership there are quite a few home foundry owners who may well chose to make their own patterns as mentioned in the book.
Tom is a very capable fabricator, if you have seen his other engines you will know this and that is why he has gone down the welded fabrication route just as someone with a decent size CNC may choose to cut the parts from solid.
J
-
JasonB:
Of course. You're absolutely right. I forgot who was going to read my comments. For many, making patterns, and doing castings from scratch would be child's play, and their machining skills are very far beyond what I think I can do.
That said, the engine presented in this build thread, is a revamp of the design shown in the book.
I stand, corrected.
Frank
-
Tom....
Having only joined this forum within the last day, I have many questions about your engine which I would have asked at the time when you originally posted photos, etc. Now I have to play catch-up, but will hold off asking until I see where this thread takes us. Perhaps my questions will be answered in future postings by you, as the project/engine nears completion.
Very interesting, and well presented project.

Hi guys
I have been working on getting the engine started. The bike frame and engine was fastened to my work table and a electric motor was also mounted to turn the engine. The engine fired a couple of times and twisted the center out of the aluminum pulley that I had mounted to the crankshaft. It looks like if I am going to start it this way I need a one way clutch on my pulley. all the other engines I have built had big flywheels and just by turning them they started right up this engine is a little different beast and will take a little more effort. I may need to go ahead and build the kick starter and start it that way.
Frank welcome to the Modder. The book helped me to get started on this engine but it didnt take long for me to go my own way. The crankcase is sealed with gasket sealer and will probably leak a little. I will get the gear and rod spec. next time I disassemble it.
Jason thanks for helping Frank out.
here are some pictures of the bike. I remade the handlebars and have been working on the tank Tom

Tom...
Thank you for the kind acknowledgements and for giving us such an interesting build. You engine is most interesting to me, and thanks for answering some of my many questions. I have more, but I'll wait. Now I know that you used sealant on the crankcase seams.
Any chance that you will do some drawings for the critical parts of the engine, like the piston, head, cams, and their gearing dimensions, lifters, rocker arm measurements, etc? The rest of the engine looks like it could be built from your posted photos.
Jason has helped me in the past, and will probably continue to help me into the future...and I thank him for his friendly gestures. : )
Tom...good luck getting the engine started. Tell us what's going on with it, and how you solved the problems. If you had to do it over would you do it the same way, or, would you make changes to your engine design?
Also, good luck with the rest of the bike-build. It's turning out to be a beautiful looking machine.
Kind regards,
Frank

Good to see you making progress Tom , its going to be one cool machine once its all done :drool: :drool: :drool: :drool:
Keep up the good work :thumbup:
Cheers Mick
-
Thanks Frank and Mick
Frank when I have it apart I will take some measurements for you. as for changes I would use roller bearings and seals on all the shafts. I think I would build the crankshaft different , no taper on rod pin.
I got the engine running and it runs ok .it is balanced a lot better than I thought it would be. I am running a old mixer off of a stationary engine temporarily. the first carb. I tried was of a 7 hp Honda and would not supply enough fuel to start it. Here is a video of it running. Tom

Can any modern ignition coil, etc. be used to spark this kind of engine? The magneto is from the period, but for demos and shows, could I substitute a more efficient, compact, easier to conceal system, to fire the engine?

Anzaniste...
Just wondering if any alternative ignition systems would work other than a Magneto. If I am successful in building this engine, I will only run the engine for demos and possibly at outdoor shows. I just wondered if anything else could be used for sparks. It's nice to have options.
******************************************************************************************************************
@ Forum Members:
Questions.....
I have some thick-walled (0.3750") steel tubing that I can use for cylinder material in lieu of a cast iron liner. Can I run a 6061 Aluminum piston with cast iron rings in the steel tube? Should I just buy a commercially available piston, and ring set?
This engine is air-cooled, and designed to have fresh air blowing across the cooling fins for heat dissipation. Will cooling fins be adequate for stationary demos and intermittent running at shows etc. With the large amounts of iron mass at the top of the cylinder, will this be enough of a heat sink to keep the engine at working temps? Do you think an accessory fan blowing across the engine cylinder will be needed?
Thanks for the help.
Frank
-
Thanks guys
Frank I built the mag. its not really a mag. it just has a set of point in it . The battery and coil are hidden in the gas tank shell that also has a small gas tank in it. you can use the a steel liner and aluminum piston with cast iron ring for your engine if you don't plan on running it much. As for the cooling it helps to run low octane fuel like coleman. No fan needed. I got your mail. it might be easer if I call you to answer some of your questions. Tom
-
Tom...
Thanks for the new, and unexpected information regarding the "magneto", the cooling, and the fuel recommendations. Now, I may want to re-think my piston material choice judging by your answer..."if you don't plan on running it much".... These last few words have me a bit concerned. I'll be a little more specific when I contact you in the near future. I want to get some materials, and questions ready.
Many thanks. Looking forward to new photos, and postings.

I've been following you on this build great job!! the flames out the back could be the exhaust pipe not sealed and some air getting in or it may be too much gas being a one cylinder. An old amal carb would look sweet like a pre-monoblock or a t.t series http://amalcarb.co.uk/ .
Another thing I just remembered I bought my norton back in 74 the problem I had with it was it would kick back when starting to the point of not being able to put pressure on the foot and would occasionaly backfire no matter how many times I timed it or had the shop look at it nothing could be found out of place. It turns out the auto advance unit was worn causing the spark to fire at various times. So by looking at your video the chain drive to the points should have a slip or a idler to take up the slack.
Tom
-
Thanks guys
Osselton thanks for posting the carb. link. mabey I can find one of them. it would look real nice on this engine. if the chain slack gives me trouble I will add a idler good call on that. Tom

What a fantastic project, i have followed it with interest, great work, and brilliant to hear it run, well done.

bit though, i think i understand the principle of it, but can't figure out how it works in practice with regard to
actual machining or holding compression etc.
Think i will have to do some more research on the subject.:scratch:

Bronx, it is possible that your problem is just a setting in your browser. A browser is another name for MS Explorer, or Firefox, or whatever you are using to view this forum.
Some browsers, like Firefox, have a setting which will display animated images only one time, or as many times as the image specifies. You can choose either.
I'm not sure about this, but maybe that is applying to the video you are trying to see. You get to see it only once because that is what your browser is set to. You can probably change that to allow it to display it multiple times.
If you are using Explorer as a browser, there may be a setting in it that does the same thing. You will have to find that to change it --I actually don't use either browser.
But the symptoms of what you describe sound like that. Able to view it once, but not more than that first time.
Sorry I can't help more.

Frank

Probably my 40th time reading through this build tutorial....
Questions for Tom:
1. If you had to do the engine over, what would you do differently, if anything?
2. Why the split crankcase? Was this design chosen for ease of assembling the engine components....i.e. the crank with con-rod, and piston...and does it leak oil at the seam?
3. You mentioned that you would NOT use a 3 degree tapered crank-pin to hold the large end of the con-rod. Can you explain your opinion, please? Why?
4. While testing and running your engine, did you find the design that you used to have enough cooling fins, etc. to keep the engine from overheating? (If/when I build a version of this engine, it will not be mounted on a motorcycle, but instead I will run it for displays, etc. Will I need a fan to blow cool air past the engine for adequate cooling?).
5. Did you have to modify the double, flywheels for better engine balance.... i.e. add weights, drill holes to remove metal, etc?
Thanks.
Frank
-
Frank some how missed your last post. I will try to answer your questions.
1 add ball or roller bearings to all shafts , make the rod out of alum. ,cast the crankcase out of aluminum.
2 for ease of assembling it does not leak at the seam but it does leak around the shafts a little. there is a pin hole in one of the cases at the top where I welded it together and when the engine is running it leaks there I call that my oil presser gauge :(
3 cutting the tapered rod pin holes was hard to do with the tool I have, they need to be dead on, I think the new bike engines use straight press fit with no nuts.
4 it does not run hot just idling , but about 15 minutes is as long as I have run it. more testing needed.
5 yes sir John posted a link to a book that was a big help in balancing this engine look back at the beginning of this thread for that link.

The saddle looks great (but I wouldn't want to ride too far on it).
It seems that there is no end to your talents.

Saddle looks bit.. uncomfortable.. You should take a look at how the made old spring suspended seats (basicly an outer frame, with a plate in the center alot of springs) then cover it with some closed cell foam and then wrap it in leather.. (theres alot on this subject in biker forums and chopper build books, that usually make old scool / 20's styled seats)

It's ALL looking good Tom! :clap: :clap:

Top work Tom , it just looks right to me , the whole bike that is............. I would think your machine will get more attention at a show than some of the real expensive custom type bikes as it oozes character and looks functional with class :bow: :bow: :thumbup: :clap:
Keep up the good work

Tom, Details of the kickstart please.
Is it just for show or how do you get it to come out of mesh ?

Thanks for the comments it keeps me posting.
sir John go back and view the video on post 145 and it will answer your question.
Guy the seat is correct for the time period I am tying to represent which is the teens. I know it is not comfortable but I think in this time period if you did not have to walk or peddle a bicycle you did'nt care how comfortable you rear end was :) . here is a couple of pictures I used to build the saddle.

Excellent workmanship as always, Tom! Looks period, and to me, looks cushy compared to a tractor seat. Gosh springs, and leather! And it seems wide enough, too. :thumbup:
It's the narrow ones that get you. :whip:

Your doing a great job but what was that seat attached to in the pic. :drool:

Hello TomT and others-
Just thought I'd check back to see any new postings. The bike is just great, and finally, I was able to see the engine videos again.
Because of this thread and my interest in similar engines, I have found and read many interesting sites, and viewed some incredible videos showing home-built motorcycle engines. I thank everyone for the links, photos, videos, suggestions, etc, especially TomT for taking the time to answer everyone's questions.
Continued good luck TomT.

Good luck with the rest of your masterpiece.

Not to decry Toms effort but as he posted at the start of this thread this was all from a 1906 book published for the amateur engineer in the days of flat belt treadle lathes and no milling machines.
It makes you wonder what we have lost in the intermediate years ?
As a reminder a link back to the original book.

Hi
Following this thread with great interest as a biker from way back.
I bet that OKTomT is as pleased as a dog with a bellyful of pee being turned loose in a forest.
Bike looks and sounds great.
Wonderful vision and skills demonstrated an inspiration for all modelers
Thanks
Eric
