Title: My little Demon so far.
Post by: Doc on January 23, 2013, 10:31:25 PM
Here are a couple pics of the v-8  Little Demon I'm working on. I want to get the valve train done or close to done and the intake done then it will be put on the shelve for a while I have some other projects I need to get done and I pick it back up next fall. But so far I'm enjoying this build and things have gone pretty good. But shop time has been harder and harder to find.

Hiya Doc!

I understand about shop time being hard to find. I don't think I have really done anything in the shop for myself in the past year or so. It has all been building bike bits to sell...

I digress, on to your build. It is off to a great start. The Little Demon? Is that Steve Hucks design??

Thanks Eric
 Yes this is Steve's Little Demon design he has done a very nice job on his drawing package and I can't thank him enough for offering them. I just hope I don't mess them up too badly.

Lifters done I think I may start the crank next.
I'm going to have to stop here soon I have some other pressing thing that I need to do so it will be shelved untill next fall soon. (so I keep saying to myself) :scratch:

Well I decided today to put the V-8 on hold until next fall. As the weather gets nicer it is harder and harder to find time for the shop. I have 120 trees to plant this spring and then take care through the summer along with all the gardening and yard work. Anyway today I found a little time to work on the rockers and a rack system to mount them. I'm doing it a little different than the drawings but anyway I just set them in the head to get a feeling of how they will look still have work to do on them. I packed everything into a box and it will be setting on the shelve waiting for me in the fall.

I haven't posted here in some time but I am continuing the build I'm working on the spark plugs now. Here are a couple vids I did one from start to finish just to make sure my deviations from the plan would work out ok. I have turned up the insulators using my CNC mill I have a video on youtube of that also. Anyway I'm doing the spark plug bases in multiple operations I have the first 2 operations done making 20 plugs.

Ok I got to the swageing and got them all done next will be the hex but first I need to go and try to do some plumbing work at my father-in-laws they have a valve leaking so don't know if I'll get back to it today or not. Isn't that just the way something always coming up to keep you out of the shop (darn it anyway)

Ok I got about half of them done. Just didn't feel up to it today don't know why just feeling down a little. The ones I did get done worked out pretty good. Only thing left after this is the washers then they are done and one more thing I can cross off the list of things to do. I think I'll sit down and plan a attack plan for the water pump next and start thinking about the radiator.

Ok got the first half of the pump done to day and got the second half all modeled up and the first operation for it programmed.


On the first half of the pump I flipped it over and milled a pocket on the back side.
(http://i913.photobucket.com/albums/ac331/doc0455/My%20V8%20build/water%20pump%20base%203.jpg)


Then cut the side pieces away.
(http://i913.photobucket.com/albums/ac331/doc0455/My%20V8%20build/water%20pump%20base%204.jpg)


And then cut the tabs down on each side.
(http://i913.photobucket.com/albums/ac331/doc0455/My%20V8%20build/water%20pump%20base%205.jpg)

I made a little fixture plate to load on the water passage holes I drilled them to .125 instead of .1 to locate on them.

(http://i913.photobucket.com/albums/ac331/doc0455/My%20V8%20build/water%20pump%20base%208.jpg)


I'll probably do the second half about the same way.

Post by: Doc on January 03, 2016, 08:56:59 PM
Ok I have the water pump housing done minus some deburing and maybe some radius stuff. Next will be the gears and internal parts plus drill and put in port. Won't get much time tomorrow for shop work.

Ok I worked on the pump gears. I made up a cutter to cut them and have cut a piece of gear. I will part off the lengths I need tomorrow and get them mounted int the housings. And also I'll work on the hose fitting nipple once that is done I'll work on the fan and hub I do have a 5 blade fan modeled up. I'll get a program made up and cut them on my CNC machine. I did video making up the pump gear cutter some of it anyway and cutting the stock.

I like the tip about marking the stock centreline with the square Doc - definitely one to tuck away for later use   :thumbup:


(btw it struck me that your acetylene pressure was far too high, which was why you had problems lighting up - oh and  did you de-pressurise your O/A regulators after use  :scratch: )
Title: Re: My little Demon so far.
Post by: ieezitin on January 10, 2016, 10:49:29 AM
Nice little set-up you have there Doc... you do great work.. very interesting..  I am far from young folk but i liked your tip on the + X,Y,Z something i shall remember that..

My small torch which is identical to yours has exactly the same problems... if you don't use it often the tip my have crud init or check your pressure settings on the gauges.

Thanks for the video.

Anthony.
Title: Re: My little Demon so far.
Post by: Doc on January 10, 2016, 11:00:12 AM
  Thanks guys yes I did relieve the pressure on the regulators. I have messed around with the pressures but still gives me a problem when lighting some time. I'll have to check the pressures again and make sure they are not set to high. I just have to let it burn awhile and it will eventually let me add the oxygen. I do hardly ever use it so it mostly just being used for heat treating stuff and a little silver soldering.

Well I'm heading to the shop and get going on the water pump before the day is gone.
Title: Re: My little Demon so far.
Post by: awemawson on January 10, 2016, 11:11:22 AM
Many people forget to set the oxygen and acetylene pressures with the torch tap open and gas flowing - it makes a big difference. I use about 2 psi on each with an absolute max of 4 psi

I looked at my pressure again on the acetylene and it was high I adjusted it to where I usually have it and you are correct lights right up no problem.
Thanks Andrew!


I was setting the gear lengths and had them fitted and dad burn it anyway I dropped one. I spent the next hour and half crawling around on my hands and knees. What the frig I must have a shop gremlin and he has taken possession of it. And don't you know I didn't make enough gear stock to get another so I guess I'll be cutting gears again.

 I did look another half an hour then went forward with the one I had and put together the one I had. I grabbed a little container of water and a empty container and tested the pump.
I must say I was impressed by the way it pumped. I used a dremel tool and set on low it pumped pretty good but turn it up and it shot water all the way across the bench.

Good to see the pump works , I make gear cutters the same way but , I drilled and taped right across the holder ,and cut the rads with the blank pushed away from the centre , this gives clearence when it's clamped towards the centre , iff that make any sence to you .

Kind of like if I make a cutter for steel gears then I do the turning of the tool at a smaller dia then when I go to use it I pull it out or extend it out of the holder about .25 farther than it was made at ten I get a relief from the cutting edge. In brass I don't mess with that as it is soft enough as long as you take it easy it will cut just fine. I like your Idea I may have to put a couple set screws in from the other direction and give her a try. Thanks!

Nice Doc  :thumbup:

What's your secret getting the double sided tape unstuck after machining? I've tried various makes, including carpet tape and 3M proper hold down tape, and always seem to spend more time removing the glue residue than actually machining !
Title: Re: My little Demon so far.
Post by: Doc on January 17, 2016, 10:28:04 AM
A small torch and heat them up a little and they come right apart then wipe off the sticky stuff with some acetone.
Title: Re: My little Demon so far.
Post by: awemawson on January 17, 2016, 10:50:51 AM
... mmm ... the tapes I've got have intergalactic mega gluey 'never release' on them  :bugeye:

Yesterday I tried heat, acetone, xylene, isopropal alcohol, cigarette lighter fluid, and a proprietary 'label remover' all to no avail. I ended up patiently 'rolling it off' bit by bit. Well in all honesty not very patiently.  :ddb:

The one thing I've not tried yet is freezing them. I know it is how they remove chewing gum from pavements !
Title: Re: My little Demon so far.
Post by: Doc on January 17, 2016, 11:26:38 AM
 MMM I found that acetone works on removing most all goooy stuff haven't ran across any that it wouldn't remove guess I'm just lucky the tape I usually use is just the carpet layers tape. Anyway  to get them apart I usually heat them with a torch or put them into boiling water (for small parts).
              Well it's -15 degrees f so its a good day to stay inside and work in the shop.

If it's any consolation, you'll find the gear you dropped just as soon as you make a new one.  (Don't ask me how I know.)  Keep up the great work.

Post by: Doc on January 18, 2016, 06:28:28 PM
Haven't found the missing gear When I made the replacement I made extra stock this time ( should of done that first time) I have enough left over to make several spare sets of gears. I'll put the extra on the shelf I'm sure I'll find a use for it eventually.

Title: Re: My little Demon so far.
Post by: Doc on January 30, 2016, 07:12:49 PM
Well made it out to the shop and worked on the cab's main body. Thing were (I thought) were going pretty good hen I noticed I put the holes in the carb 90 degrees from the plan  :doh:   hmmmm drats! I'm thinking it will be ok though just means the cab will turn on the manifold 90 degrees. I did video the work today most of it a little over 2 hours I'll process it and get it uploaded to Youtube tonight and should be there for anyone wanting to take a peek tomorrow.
  I'll finish up the main body tomorrow and get a start on the 2 other pieces and see if I can get it done this weekend. After this I'm going to attempt to set the cam and start putting ting together for real.

Ok for some reason youtube didn't like that video format on the long vid it sat and said processing for a couple days so I deleted and cut the vid shorter it just got released so here it is. I have a dam cold didn't feel I could make it to work but funny thing I did make it out in the shop for a bit today.  Imagine that anyway I'll post another vid from this week end when I get a chance. The cabs are about done just need to turn up the barrel and get the jet needles done.

That video was recorded on Sunday and Monday wasn't feeling up to par so I took a vacation day from work and forced myself out in the shop for a little work and by the evening was feeling really bad! It's now Wednesday and still feel like CRAP! This is a really bad cold I've picked up.  Seems like where I work the yayhoos that work there seem to think they need to be at work sick or not so they can spread it around. Really piss's me off in a way. I'm pretty darn sure that its where I picked it up as me or my wife have not gone out anywhere for a week before I got sick. Anyway that is one of my biggest pet peeve IF YOUR SICK STAY THE HELL HOME!
   Ok enough ranting this is the video I shot for the short time I was out in the shop not sure when I'll get back out depends on how fast I can kick this dam cold!

Man am I fighting a bad cold it's been hanging on for a week now. My wife is now coming down with it. SO not sure if I will get anything done on the build this weekend  :(  Maybe I'll feel up to a little cad and make up a fake sump that I want to place on the bottom of the oil pan to make it look right. I really don't feel up to just typing this reply just want to lay down and take a nap. We in a winter storm watch this weekend so I may get to play with my tractor and snow blower. Anyway I'm going to go take a morning nap :(

Well I finally made it out to the shop yesterday and did a little work on the carbs. I didn't feel up to it but I forced myself to get out there.
  Today I hope to get some time in this afternoon I do have to go move some snow but not a whole lot didn't get nearly what they were predicting. I really don't mind moving snow actually find it fun. I put in the vid my fav winter toy and you can see why I don't mind it.
  Anyway carbs are about done just the needles and the linkage left to do.

Haven't been out in the shop for awhile but made it out there today for a little bit. I primed and painted the block and oil pan in a little cardboard paint booth I threw together.

Ok worked a little on the cam I cut off the indicator dia on the end and then I pressed on the bevel gear and got the bearing installed. So it's ready to be put in place and set when I get things put together that far.

  I have a few end mills to sharpen before the weather gets nice and I head outside. Plus I want to make a few carbide boring bars. I mat set the camera up and show the whole process and my set up for sharpening. I'm going to attempt some small end mills.

  Well she was cool outside this morning again plus wind was blowing felt pretty cold out so I spent some time and put gears in place. I need to go and find Steve's video on setting the cam up and get a degree wheel made up and get it set.
  Plus I want get some dull end mills sharpened (I may video that from start to finish).

Anyway got the gears in place and they seem to work fairly smooth so once I get the cam set then I'll need to go back and cut out some gaskets.


It got pretty nice out side this afternoon but got windy and cool late in the afternoon and windy so I went back out in the shop and cleaned a few things up and printed out a degree wheel and now I'll glue it to a piece of plexi glass and band saw it out plus make a hub that I can mount it to the crank. (or I could run down town and but a round compass) na that wouldn't be as much fun as making your own. Hahaha

I did a little on the engine build today I had been putting off the dampener pulley because I didn't have any 1.0 dia aluminum stock I do have quite a bit of 1.625 so I finally decided to go ahead and turn a chunk of it down. So I got them done yesterday now I'll attempt setting the cam if I make it out there today.

Was going to mount rocker system (rails and rockers) and realized I didn't drill the mounting holes yet for them. SO dug out the fixture and created a program to drill them. I just need to find time to get out in the shop and do it. Anyway once I get that done I can get them mounted and size up the push rods. I keep meaning to get started on the gaskets but still haven't. Anyway very windy here today so I may make it out this evening for awhile.

 Here is a video from yesterday. Today didn't make it to the shop. I will get the rockers mounted and get started on gaskets I hope next weekend. I did drill all 4 heads I figured why not do them all as it doesn't effect anything if I go with the original rockers. I did set down and do some deburing  and set up to cut down the area for the lock nut. Anyway I am getting closer every time I spend time in the shop so thas a good thing (I think) .

  Well made it to the shop for some time today between yard work and other things I had to do. I did try out the new hob cutter and did video it.
 :doh:  :doh:  :Doh:
 I did show how to machine gear without a rotary table or index head. It's processing right now and I'll get it up loaded tonight. Take a look and see if the cutter worked or not when I get it up loaded.
  Until then catch ya later.

Well I did get the video uploaded and I really am going to change the way I cut my gears. It will be using a hob cutter from now on it worked out so well. Anyway my next trip to the shop will be to set up the timing of the cam in the second Little Demon engine.

Here is a link to the video if you care to take a look. I attempt to show how to make a gear without a index head or a rotary.

 Well I cut the head gaskets and upon looking to start assembling I noticed a boo boo , Oh crap the coolant passage and has an error. I ran into the counter bore for the head bolt for the passage that goes to the intake manifold.  Crap! and I didn't drill the hole for the passage in the face of the head. So now I need to come up with a repair plan. I'm thinking of reaming up the counter bore and pressing in a spacer to the bottom of the hole but first I need to take the counter bore a bit deeper to give it a sealing wall so it wont leak. Then maybe mill a passage in the face of the head to connect to the block coolant passage. Anyway I may do a video showing what I'm talking about here.

Hopefully I won't find too many more boo boo's.

    Had a bit of an incident in the shop last Sunday. I was out in the morning and the shop heater was acting up. So I decided to change the thermocoupler. I was standing on a small step stool and it decided to skip out from under me tossing me to the floor. I landed flat on my back. Unfortunately in the landing zone there was 2 pieces of square tube! It felt like I broke my back took me some time to get my breath back. I ended up going to the doctor the next day x-rays nothing broken just bad bruises and a 2 inch gash on my right arm. I was put on 2 pain meds and a muscle relaxant. Man I could not move at all for the next 3 days! I feel much better today and am going to see if I can get out there and do a little work this afternoon.

Thanks Andrew!
  I've had my trouble with spinal injuries. About 20 years ago I had 3 disks bulge in my neck and I was paralyzed on my left side. They went in to cut the disk away from my spinal cord to try and get control back of y left side. I did get most movement back but still have little tremors sometime in my left arm. I have been pretty careful for the most part not to end up in that situation again.
  I was out in the shop but just felt not all there so I came back in and am going to sit back and vegetate again today. Maybe tomorrow.
Here is a pic from about 20 years ago after I got out of the hospital.

 No work on the v-8 yet but did spend a little time in the shop putting on the coolant addition I've been wanting to do.
I now can control the coolant on my N/C machine outside the program and also have air mist if I don't want a full flood and I can control it manually or with the program.
  I have one more machine mod I want to do and that is to put a variable speed feed and control on my lathe. That way I don't have to stop and change gears to change the feed rate.
  I did work on the second engine's push rods and rockers a little today plus made a mold for spark plug boot and filled it with a silicone material to test it before I use the liquid rubber I have for it.

  Well I made a small mold and tried the rubber stuff I got I must say I'm disappointed with the stuff. I have not gotten it to set up at all just turns to a thick goo and never sets up all the way. I thought it was my measurements but I used syringes to measure exactly still no luck   :scratch:  I applied a little heat still no luck. I think the stuff is bad I may have to go with the stuff Steve used. I did send a note to the seller I'll wait to see if I get a response.   
   So for now the plug boots I'll put on hold and work on the exhaust pipes and gas tank and think about the radiator.

  No I had changed my mind on the seal stuff what I was using was some stuff I found on Ebay that is 2 part rubber suppose to get to a 60 shore hardness (more like a hardness of peanut butter). I had decided the flex seal wouldn't work as it sets up in the presence of air and in a mold it wouldn't work. This stuff I have is a two part rubber and doesn't need air to set up (supposedly)

 I did get 2 pieces of copper tube cut and cleaned up (salvaged tube) and ready to be made into fuel tanks. I didn't have the dia in the plans but did have some 1.625 OD so it should work. I'll work on the fittings and stand and getting the fittings soldered in place. Then after that I'll work on the plug wires. I'm starting to get excited   :ddb:  shouldn't be long now before trying to bring them to life.

I did get a new camera it is a knock off of the GoPro I did do a little test video to see what the quality of the video would be. I did do a video today  and am posting both here.

Moving right along I did decide to do both tanks the same not sure if they will receive paint or not. We had a ice storm yesterday and the power was out a few hours yesterday evening. I spent this morning moving snow and will probably end up doing that some more in the morning.

Wheeeu    had to take a break from moving snow (manually with shovel) and have a cup of java. :coffee: Ive been at it over 2.5 hours! This stuff is some heavy snow being it was mixed with freezing rain. Not sure I'll get any time in the shop today as when I'm done with our snow I get to do my in-law's. They live on a corner lot so I get twice the fun on two sides (hahaha) Plus an extra wide drive way(thank goodness it is but 30 feet long though). I'm rendering the video from yesterday while I have my cup so when it is done I'll start it up-loading.

Didn't get a whole lot done today we had power issues with brown outs and black outs.
 I started out by working on the plug wire ends. I took an ink pen with a brass cartridge (same id as I needed) and parted off the rings from it. Then I was soldering the first one and boom power out to dark to go any farther. An hour and a half later finally came back on. While it was out I put together a plug wire bracket to hold 4 wires. I waited awhile to see if the power was going to stay on this time. I did go out an cut two brackets and that was it for the day. Tomorrow I'll get two more brackets and then back to the wires.

   I modeled up the pipes in cad to see what I wanted them to look like. But the radius of the bends in the tubing is smaller than any tube benders I could find.
  So I will attempt to make my own. Not sure if I can get the bends I want without the tubing crushing or tearing apart so I'll make it up and see.
    I started working on it didn't get a lot done as it was late in the day before I started anyway will work on it this afternoon.

Doc,if the tube bends are pretty tight you may have greater success if you fill the tubing with solder or melted lead before bending. Melt it all out again when you're finished.....OZ.

even better fill with water then frees then bend

Bob,I used to know a chap from the Coventry area who made hand bent exhaust systems for classic race bikes and classic cars.

He filled the tube with bone dry sand and plugged the ends with wooden stoppers. Tube held in a clamping vice then heated with oxy-acetylene torch and he would just gently push or pull the the end of the tube and produce the most amazing exhaust shapes.

That man is Dave Kirby. Anyone else know of him?

 I was going to anneal and then fill with sand but I king of like the filling it with lead I may give that a go. I have lots of tractor lead wheel weights. If this doesn't work  will up the radius to maybe .5 or .625. I just wanted to try and see if I could go down to a .375. The freeze thing as slow as I am it would all be melted by the time I got started bending it. :lol:

Doc,just do a google search for sand bending tube or pipe. There are several very informative videos on youtube.

The technique involves keeping the heat mostly on the outer side of the curve being formed.

Link to one vid here,there is loads more through google search.

I've been using it for decades  :bugeye:

Not only for bending pipes without them crushing, but also for fixturing awkwardly shaped bits for machining - just set them in a simple mould box, pour it in, then grip in a vice and machine the part. Melt out in hot water when done - save for reuse :thumbup:

Thanks for the info guys. You need to be careful some of that stuff has cadmium and that stuff isn't to good for you. We use to use some stuff at work like that to hold complex parts for machining. I may order some medical grade stuff (no cadmium) it could come in real handy.
Thanks!

Didn't get any shop time last few days we ended up with another 10 inches of snow. So I have been busy moving snow again. I did grab the camera last night while moving snow.

  Ok I did get the tanks at the right height and fuel line attached. I do need to come up with some small hose clamps of some sort. I added a short video the sound is terrible I used the new camera with  the sport case on it so now I know not to put the case on it again.  Anyway I'm going to work on the pipes and a temp coolant tank  to take the place of radiator. Shouldn't be long now I do have some mis things to wrap up but hoping to be able to give it a try next week end. Depending on how the bending and pipe thing goes

PS I did get the new batch of liquid rubber haven't had a chance to give it a try yet. I sure hope the stuff setts up this time.

  Ok have exhaust pipes done for now so on to the plug wires again. I think the first thing I will do is make some wire organizers. The silver soldering went pretty good for the most part. I did solder one with the video camera running. I may end up painting the set that will go onto the engine that I have put paint on.
  I also got the new set of liquid rubber stuff that the first batch didn't work (wouldn't set up beyond black goo) I hope this stuff will work. It is suppose to get to the hardness of tie rubber (according to their advertisement) I'll probably try the stuff out this week. I'm hoping the cold temp isn't what caused the first batch to not work because when they delivered it, again it was well below 0 degrees f.

Nice work George.   :thumbup:

I have been wanting to order the plans for the Little Demon for awhile now. I went so far as to get a set of gaskets off Steve when he was selling them. I just need to order the plans and have the time to build it. I keep postponing... But reading your build is starting to inspire me to order the plans.

Keep up the good work!

Eric

Post by: Doc on January 10, 2017, 01:13:01 PM
Thank Eric !

I purchased the plans when Steve first offered them. I do design work and drafting so I know how much work goes into this kind of thing and I couldn't believe the sweet deal he offered so I jumped on it. It has been a fun build but I've been kind of slow at getting things done but I am getting close.

Here is a pic of the first boot I'm uploading the video of me removing the cores and taking it out of the mold. I had trouble getting the cores out the next one I put a little more Vaseline on the cores this time. The rubber did set up pretty nice this time.

Nice work on the boots who did you get the kit off of. Are they as hard as tyre rubber like they said?
If you decide to scrap that one or have some scrap about it would be interestimg to see what happens when in contact with oil / gas.

 First out of the mold it's not as hard as a tire but after setting another day I'd say it's close. I got it off ebay I'm happy with the hardness and the stuff has some tinsel strength. The first one getting the cores out I had to use a pliers and I twisted the crap out of the stuff and only suffered a small little tear.
   I fixed the little tear when I mixed and did another boot I dabbed a little on an now you can't find the tear.

 I redid the mold to add a little collar around where the plug goes into the boot once I get it the way I want I'll create a mold to do 4 at a time.

Ok next version of plug boot this style has a small ring at end still not sure how I want them to look. I'm sure some of you are thinking how long can he mess around with the plug boots? 
       When I decide on the style I want to go with I'll build 2 molds each with 4 cavities so I will be able to make 8 at at a time. I did find that about the shortest un-mold time is about 2.5 hours and once removed letting them sit in a warm place for 5 or 6 hours the harden up to a nice hardness of pretty close to tier rubber so I am very pleased with the way the stuff works.

Didn't make much headway today was my father-in-laws 94th birthday so not much done in the shop.
Just need to get some distributor boots done and some brass pins then I can start putting wires together.
Been thinking about  the radiators to come and how I make attack that.
