Another situation where my lack of GD&T knowledge has bitten me, the method used in the documents is listed in your link.
A question for you. I have access to a lathe(with a four jaw chuck and the usual kit), verticle mill, and a hydraulic press. I recognized at the start of this project that the internal camming surfaces would need something weird to actually impliment, and with more knowledge I have come to the conclusion that I would need either a machine capable of live tooling or a shaper(though I am not sure how this would work, only that people recommended this method on a machinist's forum). My plan for this is to do some engineering to make a mini-shaper that grinds out the cam incrementally; however, on revisiting the documents I've realized that I overlooked the raceways in the receiver.
How would I do these without eliminating the bolt overtravel stops at the end of the receiver? The guide which started this project (
linked here) uses ground down standard sized broaches to get them to near finished, then a file to get the final profile, however this method eliminates the overtravel stops as previously stated. The only tool that I can see being able to do this is a shaper, that is unless I include the idea into the 'mini-shaper' concept said previously.
I don't know. What is your take on it? Am I missing something that is obvious?
Either way, I need to revisit my kinematics
