MP alignment pin question

[justindad]

I did this same thing with good results. The male pins seem to push out the female sleeves if you go too far. I’ll add that you might benefit from adding some lube to the pins in case the male & female parts stick together.

After using my mold with reset pins a bit, I noticed the alignment pins were a little sticky. The male pins were too far out, but not so far as to let light come through the two mold halves. So I cut cigarette papers into strips, placed two strips over the female alignment bushing, then attached the mold half with the alignment pins to drive in the paper strips, then add two more strips (4 strips per hole), then assembled the two halves to drive in the papers without cutting them. Then I pushed the pins out a bit with an arbor press, reassembled the mold halves, and then pushed the pins in until I knew the male pins were touching the female bushings. Now the pins fit perfectly and detach smoothly, although my bushings moved ~0.020”.
