vintage engine build

Tom, between "intro to Lean" and "Manufacturing Machining" class, I opened this thread and showed some folks your pics. People went about nutz, lol.

In the great words of Tina Fey; "I want to go to there."

Tom, excellent work! Kudos. I have some questions though. I didn't see any oil seals on the shaft cases. Are there going to be oil seals? I would imagine leaking oil would be quite vintage

. Do you think that modern roller bearings would be a good upgrade rather than bronze/brass bushings? Even in an oil bath the bushings will eventually wear and the leaking will go quicker.

Tom TG · Mar 9, 2013

Dan I am glad they enjoyed it. Are you the instructor?

Cobra these old motor had a total loss oil system what it didn't burn it leaked out. The book shows you how to build a drive belt pulley that has a cavity in it to catch the oil that leaks out of the drive side case. It has a drain plug on the pulley to drain the pulley. Roller bearing and seals is a good idea but it takes closer machining tolerance, Thanks Tom

LOL Tom, no. Lowly student and 48 yr old freshman.

I needed a $3 bushing for a 5/8 PTO to fit a 3/4 driven clutch. Instead of buying one and Micky Mousing it with a grinder, I bought an endmill for $800.

It shows up and is a 400 LBS behemoth and to big to work with in the garage.

So I build a workshop in the back yard. (really wanted one anyway)

Then, in trying to teach myself to operate it, thought, I should get some training. Apply and get a grant to attend a precision manufacturing certificate course.

So, about $16,000 has traded hands.

......and I have yet to make the *&%#@)7 part. LOL laff

That is cool about the seals. I wanted to ask as well.

Yep, it's a Sickness and I for one am glad there is no Cure...
Nice job on the Engine Tom

ArtSpeed · Mar 13, 2013

Very nice engine. I may have a chance to buy one from you.

dmb · Mar 13, 2013

worm seals work great and their free. a coleman pump works great on the oil tank to pressure the motor and you can put a gauge on the tank. then drop the lost oil on the chain's or out the exhaust.

I have made a little progress on the wheels. a lot of time went into what you see here and they still need some more work done to them but I think I like the way they are looking . what do you think? Tom

Dan · Mar 17, 2013

Wow Tom, that is incredible. I know what kind of work and head scratching went in to most of that. Not a clue how you bent the rims so perfectly unless you have a $100K bender lying around. (been working on that one for a good long while, myself)

Really raises the bar on the functional art thing!

Holly Smokes Batman what size spokes are on there and what rim did you start with.

silverbear · Mar 18, 2013

Stout! I have no idea how you managed to pull this off. Wow.

Tom, your wheels look better than originals.

You've obviously been at your lathe again!

I love the way you have the spokes going straight into the hub, very nice custom work!

Vintage wheels below and yes I have a contact for these:

Complete wheel:

However, these are for real or reproduction Board Track racer's, wouldn't be practical for a Vintage Tribute Style ( Motorized Bicycle ), Build.

Tom TG · Mar 18, 2013

Thanks guys .
This is how the rim was made.
First a piece of 2 by 1/2 channel was cut 16 inches longer than the radius.
The channel was put in the mill and the spoke holes were drilled at 7 degrees every other one drilled from the opposite direction . These holes were drilled with a center drill with a .250 pilot on the end .Which made a .250 hole with a 60 degree taper.

After the holes were drilled the channel was put in a home made ring roller and rolled to proper size.

Dan · Mar 18, 2013

And again I say! (lol, in my head, in an English accent

Wholly Mother of good! Uber cool and I can make that!

Dude, dude, dude. (and I never say dude lightly) Dude, that is amazing.

Brain numbingly simple and akin to wow, why TF didn't I thunk of that? typ stuff.

Years back I knew a guy who was an actual finish carpenter. The guy was really amazing. One day, I forget what I asked him but his reply was; "I can watch a man pick up a hammer and know if I am the master or the student that day."

I'm-a gonna STH up and wait for pictures. (but if you express in words Tom, type slow. Takes me a while)

.flg.

dracothered · Mar 18, 2013

Tom all I can say is...

OMG (Oh my gosh)

Tom TG · Mar 22, 2013

ok I think I have it figured out . A chain from here to their and a belt from their to here and a few bent tubes a tank and just a few more part and I am done

charliechaindrive. · Mar 22, 2013

If it was only that simple! But you should be able to create a show stopper with the skill you have!

truckd · Mar 22, 2013

Will you be recreating a BTR or Cruiser?

Tom TG · Mar 22, 2013

Thanks CCD
Truckd I really like the btr but need something a little more comfortable. It will be a cruiser springs front and rear with fenders .

truckd · Mar 22, 2013

Any particular brand or make or will you go with your own design, looks really good at this point can't waite to see it done.
