ok, over the last couple of years, i have posted several questions pertaining to the lever popping open on my 1895G 45-70. i have tried replacing all of the lever parts, with only a slight gain in the real problem. so, my next part is the locking lug. i ordered a new one, and when it got here, i measured it. it was .008' wider, and .006" thicker than the stock one that came from my gun. the stock locking lug pretty much flops around in the receiver. so i went about the slow and tedious job of hand lapping the lug to make it fit into my receiver. after 3 hours of lapping, checking to maintain square, and checking to see if it fits, i finally have the lug fitted, with almost no clearance.its tight enough that i can not fit a .0015" feeler gauge between any of the parts, but it will cycle, but rather "catchy". the only way i can think of to measure headspace, is to use plasti-gauge between the bolt face and cartridge case. at this point, my question is, is there such a thing as to tight? other of course, that the action working on the jerky side.
