Crankshafter   back in the fall I bought a 1930 model A ford that had a bad motor so I have seen busy overhauling the engine. I have that done now so I can get back on the engine.
 I have been looking at different way to build the valve train and would like to have all of the push rod  line up. For me  doing it this  way is the hard way. Here is a picture of the car and valve train I am thinking of using on the engine.

Hello Tom-

Can't say or add to anything that has not been said before.  Just another wonderful tutorial showing what can be done with just some simple weldments, bar-stock, and the guts to forge ahead and  do what needs to be done to make a USEFUL engine that will actually do something.

Thanks for sharing, and documenting all your failures and triumphs.  Very inspirational.  (My secret "bucket list" includes fabricating a larger scale, made-from-weldments/barstock, inline, twin, or, 3-cylinder, air-cooled engine).  Your tutorials showed me that it can be done.

That's a beautiful car.  :thumbup:

Can't add to Jim and Frank's comments.

Looking forward to more engine adventures.  :D

Tom,
Valve train looks fine to me, proven design so why re-invent the wheel.

Tom, anybody....

Trying not to be a PITA by asking questions, but I have a few....

Have you found that your air-cooled cylinders are in fact, adequately cooled by the cooling fins, or, are you experiencing any overheating problems?


Just curious.  Any comments would be helpful.

Frank feel free to ask any and all the questions you want to. I will try to answer them if I can but am a little slow to respond some times.
I have not had any heating problems with the first bike engine but it has not been run very hard or for long periods of time.
when I get the v twin done I plan on running it for long periods of time and with a load to see how it performs. I think having thick cylinder walls and cylinder head takes a lot of btu  to over heat but makes for a heavy engine. It would probably better to build it out of aluminum .
I am back to working on the engine and have decided on a design for the valve train . here is a picture of the mock up.
