A pic of the lumps loosely fitted to the block. I need to make one more pass on one side with the woodruff cutter to allow a bit more lateral movement, so as to line everything up before silver brazing. The front must be radiused to fit the slot. I milled the top portion within a thousand's or so and next will mill the bottom portions off to within a few thous so as to get a precise fit into the action with files, stones, etc.. My plan is to cut out some of the excess 'bites' areas to minimize final work.
