I'm trying to make a barrel nut wrench for an airgun. It's a pin spanner wrench. There are 6 pins arranged in a hexagonal pattern. Approximate pin circle diameter is 11mm. The pins needed are 2mm. I bought some undersized 2mm dowel pins. I drilled the holes deeper than the pin needs to be. Used a center boss (goes in the bore) as a stop for my arbor press. Measuring the pin circle yields a variation of 0.2mm between adjacent pins. It appears the pins aren't going in straight, although they are being started straight. These are steel pins pressed into 6061. I'm using a #48 drill for the hole. Probably doing a lot of things wrong, but this has been interesting nonetheless. Here's a picture of my test piece to the right, with part of the real piece waiting for me to figure out the magic sauce.
1 inch 6061 stock, 3/8 1144 for the rod.
