I would pass on this kit for a first lock build. You really aren't going to find better quality, and ease of assembly, than you will in a Chambers kit. And they are just good people as well. I got an old Siler flintlock in a trade, that had been built by someone that thought they knew how to improve it. I needed several parts to unimproved it, and contacted Jim Chambers to purchase them. We talked on the phone, and he ended up sending me the parts at no charge. This was a lock built before he bought Bud Siler's company. Now the only time I use anything but a Chambers lock, is when he doesn't make the style I require.
