Bob, you posted on the "Over the Back Fence" board about "Does anyone recognize...". Something about "you could have filed down the bolster." I think you meant that for me, so I looked at my builder's notes and I filed down both the bolster and lock plate (above the hammer). Lowered the lock .030" into the wood at the front of the bolster, and filed the top half of the plate .016 behind the snail.
