I just finished a mold. I had a problem with the bushings and leader pins. I made it a press fit .001 inch on pins and bushings - 3/4 pins with OD of about 1.125 on each.
Didn't work too well. The bushings got pretty tight. I eventually made it work.
Does anybody know of mold component charts as far as the fit is concerned?
I've been looking but nothing so far.
Thanks
