Hi Roger, your work looks good and you are coming right along. My only suggestion would be trying (on your next build) smaller diameter pins for your RR pipes and barrel. I've learned from the ole saying....."Drill Small, Hole Small". It kind of makes for easier repairs when I screw up, and a 1\16 inch pin does the same job that a two penney nail does, and a common tooth pick will fill and repair the hole if need be. I got one of those jap saws myself a few months back and haven't used it yet. How's it cutting for you? I think I paid around 8 bucks at one of those discount supply houses where they sell everything from Chinese lawn furniture to fresh produce.
