Mr Brooks,
I had a bit of a mental block when I first started this one. Like I said, making nails, flat sheet metal furniture. I don't know that it scared me, but I just wasn't sure how to proceed.
Once I got the nails made, which turned out to be quite easy, the next challenge was shaping the trigger guard. The profile was fairly easy. The piece of paper you suggested really helped. The hard part was "cupping" the bow and rails for strength. I ended up cutting some pieces of conduit in half, clamping them in a vise, laying the triggerguard in the pipe, then tapping with a ball pein hammer to shape. Did the same thing with a smaller diameter conduit for the thumbpiece.
By the way, nice piece of wood. Figure is even more prominent in person.
