I redesigned the push rod, the cam follower and the rocker screw. The plan call for a 0.080" diameter socket. We dont have 0.080" ball nose. So i did it with a .125" socket to be able to use a .125" ball nose.

New vs old

Other checking that you do not create other issues, like interference, I can't think of any negatives (except for those that insist on perfect copy of the original).

I'm using CatiV5, i can simulate all the movements, that's the fun part of desiging stuff in 3d ;-)

I hope i didnt miss something.

I'm not a purist, i already made changes and i will make way more in the V2.

I don't see any issue with changing dimensions, as long as it all fits together at the end.  Don't get caught making that one little change and then not being able to assemble the parts!
(following along - I love radial engines....)

I didnt refer to the Edwards plans but any particular reason you have a female socket on one lifter & male ball on the other. Or is this original design vs your modification?
What keeps the lifter aligned on the flat face so they don't rotate?

It's old vs new design, on the cam side.

The rocker side is ending with a 0.115" sphere.

For the rocker part. I'will make a one piece 4-40 threated socket screw or an adaptator that i will screw on the 4-40 rocker screw.

I didnt finished the 3d model yet. I'll post pics next week. That will be clearer than my explaination :-)

Ditto
But mine was the probe off the 3D taster got the wrong axis set on the pendant twirled the wheel ping

Shame about the bolt circle just smile and reprogram ,press start and all will be good
My aim is for a accurate part with a good finish
