Hi,
Thanks everyone for looking and commenting! I am getting my inertia back on this project. I have so much competing work at the moment that my focus on it suffered the last month or so. I really do love the gun but it is demanding at every step. There is no point at which I can relax. Even final scraping and sanding requires intense focus because I am always sanding or scraping between carved features like the moldings along the forestock and around the trigger guard and lock panels. The reward is that when done, the Hawks fowler is one of the most beautiful and high quality New England guns ever made. It is definitely in the top 5 of all surviving NE guns made during colonial times of which I have seen.
I inlet the thumb plate. Despite the weakness of cherry, it inlet well and I left it slightly proud of the wood surface as was the original.
I glued it in place with Acra Glas but also tacked in 3 silver pins. I designed the plate so that the 2 pins iin the upper shoulders of the plate are part of the engraved design. Remember these photos:
You can see the round circles engraved with the volutes at the shoulders. Those are the locations for the upper 2 pins and then I needed one lower pin below the oval cabuchon. I drill the tiny holes with a #1 drill while the plate is still glued to the wood base used during engraving. Then I pop the inlay off the wood using heat and position it on the stock. I tape it securely in place with Scotch tape. Then I tap tiny brass nails into the holes. I hold the tiny nails with a surgical forceps and tap them in part way. Then I trace around the plate with a very sharp pencil with two sides of the point flattened like a carpenter's pencil. After tracing, I pull the tacks with pliers, remove the plate, and stab in the border of the mortise with tiny chisels. After back cutting the edges of the mortise, I remove the center wood with a shallow gouge sufficient to let the plate set down partially into the mortise. Then I work the edges of the mortise along the sides because as the plate sets down, those edges have to move down the sides of the stock. It is a fiddly dance of blackening the plate and removing the wood.
When the plate is in, I redrill the holes for the tacking nails a little deeper and slightly counter sink the holes. Then I make silver nails to replace them. I use tiny silver wire and straighten a section, then thread it with a 0-72 die. The threads will capture the wood and glue in their holes. I clip a section as long as I need with jeweler's clippers, which automatically gives the pin a point. I line the mortise with Acra Glas tinted close to what the color of the finished wood, install the plate and tap it into place hard with a wooden mallet, and then tap in the silver nails. I clip the extra nail off about 1/8" above the plate and peen the excess down carefully into the counter sinks. I want these nails to show so I did not file them completely flush with the silver plate.
More to come.
