I have not tried anything yet. I am not a gunsmith but I have been a fabricator and a mechanic for 50 years and it is pretty much general knowledge that unless specified parts should not be preloaded by the mounting screws around a mounting block. That is the situation I am looking at here. The mounting screws are bending the hammer plate around that block that is contacting the barrel. I would think that the optimum situation would be contact on the wood and barrel evenly when the screws are tight and from looking at it if that were the case the hammer would be centered at the same point.
