Thanks again folks!
KD, the machine shop I used to work for is no longer in business, but they used to charge a minimum for doing walk-in work like this. That was back in the 70s so prices must have gone up, I may find someone who will do it for cheap but I'm going to give it a go (I have enough material to make another if I mess up).
Simon, I think you hit it...keeping the tube still (and not squishing it) while cutting.
Riki, that sounds like a good idea, thanks!
I have a mini-lathe, but I want to go brass this time around.
Bob, I'm going to read your article a few times until I feel comfortable about working all in brass. I was going to do the bunker in styrene but I have the brass so why not give it a try. I think once I get the slope sheet correctly positioned the rest shouldn't be too hard.
I'm in no hurry on this project, it'll probably be my last steam engine. Other than a 2-10-0 I have all I wanted for Seaboard and too many to run at one time now.
