Tom....

Just viewed the short video of THE ENGINE RUNNING !!!!!!   Congratulations on a job well done.  The rest is easy.  Just some tweaking here and there....and, you're done. 

Now, more than ever, you got me wanting to build this kind of engine, now that I know it can be done. 

Thanks, I read your suggestions for changing a few of the parts.

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?


@Tom:  You got mail.

There's nowt wrong with a magneto otherwise why would aeroplane engines use them? :thumbup:

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.

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 reworked the ignition system and put the Honda carb. back on after drilling out the jet.It runs a lot better now.  looking at this video the timing needs advanced.  Tom

That sounds great. And I do like the dummy magneto - that is very clever.

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.

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.

For yourself and maybe others interested in scratch built motorcycles, have a look at this guys website, i came across it whilst searching
youtube for homemade V twin engines, stunning work from a man in a shed.

Glad you enjoyed it as much as me Tom  :thumbup: I can't seem to get my head round the rotary valve
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:

Post # 120:

Followed the link, and now my head is about to explode.  Just incredibly inventive minds at work here and on the motorcycle link. 

Very very interesting designs that showed up within this thread.

Tom, still here till the end.

Just this minute I did a search for "Scratch-Built Motorcycles", and hit pay-dirt.

Check out  this You-Yube tutorial on how to fabricate, and machine a 155cc engine made from beer cans...yes, beer cans!  Smelted, beer cans.

Go to:  You-tube: "Fabricating and Running a Scratch Built Engine From Beer Cans" posted by Beercan Engines

Enjoy....
