Hi Folks,
It has been hard for Josh to get over to my shop because of his wife's schedule and it stormed on the last 2 dates we were able to set, preventing travel. Anyway, he made it today and we installed the barrel lugs. The barrel, barrel tang, ramrod groove and hole, and lock are now all inlet. Before starting shaping the stock, I wanted to get the barrel lugs installed. We are going to use captured barrel keys not pins. That will aid Josh taking out the barrel without risking losing small pins and figuring which pins go where. Josh used his Braille rulers to measure and mark where the lugs were to be installed. We discussed the issue of spacing and avoiding interfering with the ramrod thimbles. Josh worked out his solution and away we went. I had barrel lugs that I previously made but they needed the ends filed to 60 degrees. This is when we really tested our idea of finding the bodies "sweet spot" for filing straight or level. I showed him how to hold a lug in the vise and use a triangular file to set it at the proper angle to the vise to file a 60 degree dovetail. To do that he had to file level with the vice jaws and I watched as he set up to file and then had him shift one leg back (open his stance) which automatically set him up to file level. Remember, he cannot adjust his actions by sight so relies entirely on feel and body position. We proved the concept and I would urge everyone to think about it. When working for precision in shop work or shooting, don't fight your body. Make it work for you.
I cut the slots with a hacksaw but had Josh file the slots flat and the dovetails. He used the depth gauge on my calipers to make sure the slot was to the proper depth, however, I set the depth. I also cleaned up the slots and dovetails but only a little. After tapping in the lugs, he filed the excess metal on the bases flush with the barrel flats.
Next up was inletting the lugs in the stock. I had Josh use his Braille ruler to mark the lug base locations on the stock.
Then I used inletting black to mark the locations of the actual lugs in the barrel channel. There is no way he can see those marks so I cut the slots in the wood for the lugs. However, he could measure the borders of the lug bases, which were raised a little above the barrel flats and had to be inlet. I helped him mark those borders with a chisel and he cut out the mortices. It worked out very well.
Before cutting the slots for the barrel key, I wanted to trim the sides of the stock. I cut off the excess wood and then showed Josh how to use my jack plane to even and square up the sides of the stock .
That is where we are and more to come but be patient.
