I just tried to mount my 1928 Colt, Group Industries side plate, MG on a restored 1928/M35 tripod and the front cross pin won't go through the MG front mounting hole. But the rear cross pin fits nicely. The front cross pin is mirror smooth with no burrs and fits the tripod perfectly. I ran a caliper down its entire length and the diameter never wavers. My MG will mount correctly on a 1917A1 tripod. A 9/16" drill bit fits the M35 tripod holes and the MG front mounting hole. The cross pin can be inserted about 1/4" and then it jams. The same jam position occurs on both the right and left sides. The jam seems to be within the trunion area. Has anyone else encountered this problem? How do I polish out/ream front mounting hole? Any other suggestions would be appreciated.
