Thanks very much, everyone.....
The barrel is 42"...
Taylor; I got the silver wire through two sources. Rio Grande was one, and believe it or not, Amazon was the other. You can get just about anything on Amazon, lol... The wire I used for the dots was half hard, and something like 16 - 24 ga.
Ron; I filled the grain on this piece by using Permalyn sealer and sanding with 600 wet/dry sand paper, then wiping across the grain. On the carving I applied some Permalyn finish, which is the same as the sealer, just not cut as much. That worked out ok...I didn't want to sand the carving. Typically, I use Hurters French Red filler (from Brownell's), which I really like, but wanted to try something a little different.
Thanks again!
