RWG Technical Posted November 11, 2009 Report Share Posted November 11, 2009 Some PAM CG's as delivered come with terrible pins, check this one out...it's crappy, yeach First step is to drive the old pin out of the CG and throw it in the trash can where it belongs, then the CG is drilled with a new larger hole to accept the new pin. A piece of silver steel is fitted to a collet and inserted in the lathe to be machined down by hand to fit the CG. As the silver steel bar is turned down, I test fit the CG to make sure I have cut it to the correct size. Once the bar fits the upper part of the CG and the new hole I drilled, we need to make the lower part. Next up is to form the bottom part of the pin that fits into the lower part of the CG, it's quite a bit smaller as you can see at the tip where it's stepped down. Once the new pin fits the CG correctly, the bar is cut off, the ends are cut down and filled to fit flush with the CG, and finally the whole thing is polished and re-attached to the case. So from this: To this: A nice improvement. It takes about an hour to fabricate the new pin, all the turning, cutting, and fitting is done freehand, and polishing takes time to get a nice finish.

ubiquitous Posted November 11, 2009 Report Share Posted November 11, 2009 Very interesting to see the steps and process required to make something that most people would consider to be a very simple item. Definitely not as easy as one might assume the fabriaction of a pin to be! Nice work as always! It's neat to get an inside, behind the doors look at how this stuff is done!

P4GTR Posted November 11, 2009 Report Share Posted November 11, 2009 I don't get why everyone is making such a big deal over a small little pin. Maybe because in this case, size matters! I never really paid much attention to the CG pins. Not for nothing, that truly looks so much better. The fit and finish, perfect. Hey Zig, Thanks. You just created an eyesore out of my current CG.
