Went to a small engine show last week, and a guy there showed me how he does the cams in a lathe. Very interesting.

What show did you go to? Was it in southern Ohio?

Was the Chillton Steam engine show in Wisconsin.

Doesn't matter how you do it Steve, It looks really good. And 5 hours is fast for a cam project.

Keep it up.

I would definitely do the crank in a lathe. The cam lobe profile in a mill.
The tedious  part is getting all the cam lobes in the correct orientation on the shaft.

How much valve lift will this engine be running? and what ratio rockers. Curious.

Steve we have run flat lobed cams and flat lifters well over 11k rpms in race engines.

My thoughts, Exactly.

Steve ,
if the cam lobes are individual pcs. soldered on a shaft , then why not do the lobe profiles on the mill. Bore the shaft hole first , and clamp thru the bore to hold , and machine the profile. Lot faster.

That answers my questions. Excellent and time consuming. Can't wait to see more pics.
The crank is easier than doing a cam. Just need a couple well placed center holes. I've made a couple larger ones for a punch press years ago.
Thanks for sharing ,  an excellent project.

Sam , YES, the Hyster didn't get much farther along either. Gee's , retirement seems to make the days shorter.
I still wonder how I got so much done when I had a 12 hour job.   
There's always tomorrow.
