Making cam lobes

[charley Leight]

Maybe somebody could help to understand Graham Meeks fixture on making cam lobes with rotary table? I understand the building and assembly, but how does the stops on either end come into play. Sometimes I am dense and takes a 2x4 to straighten me out.

I don't know what Graham's method is, but I'll bet if it isn't identical to mine, it'll be similar. There was a recent Kiwi II build that went over it recently, and that should tell you all you need to know... The little computer program I used, called "camcalc" (you won't find it on Google) had moved to a different site. That thread was started by "Richard P".

Of course, if it's a Kiwi, Seagull or Whippet you're building (these shared cam profiles) Richard might even send you his figures...
