Some explanation.

I get the part where the machining starts after it's welded together.

Keep parts parallel or square to each other.

By jove. I think it will work.

Okay. I will explain Bosses tomorrow. For camshaft and valves for example.

Large engines and early gas engines had exposed assemblies. It has just fallen by the wayside.

A little messy!:)

Update.

The Flathead idea is out.

It heats up cylinder having the exhaust port below the top of cylinder travel.

I may not have that quite right but when I read original explanation it made sense.

Better to just do a little extra work and make it overhead valve.
