Howdy folks,

I am working through my first build using some scraps of Apintong that got cut out of a box truck I built a tiny home in. I’ll seal it with a penetrating epoxy then another couple coats of marine epoxy.

My question is how much larger than the diameter of the pin should I drill the pin holes to compensate for the epoxy layers? As of now the pins are 3/16” (neptonics euro reef mech) and so I drilled the holes to 3/16”. Logically I should be leaving space for epoxy but haven’t found any rule of thumb for this.

Thanks in advance!

Additional gun info:
Length - 100cm
Shaft is 130cm Rob allen. 7.5mm
Track is cut 8mm wide 4mm deep
Will use two bands - probably 9/16”?
Handle - cheapest one I could find from neptonics because I don’t have time rn.

Thanks again!
