Hinge pin shim material

[Phil C]

I have only shimmed one shotgun but it turned out great. It was a IJ 16 Gauge Skeeter. It also needed.002 of shim. I did nothing other than shim it and it worked perfect needing nothing else.
I bought a cheap feeler gauge, removed the blade, rolled it over a round bladed screw driver, cut it close to size and then used 3M 1751 2 part adhesive on the shim. Held it in place with a waxed wood dowel clamped for 24 hours.
Once it dryed I cleaned up with a file. A little dab of Mobil 33 grease and it worked and looked great.
1751 is very expensive, but what I had available from a left over aircraft project. I would think a good high strength two part epoxy like JB Weld made for metal would work just about as well.
