Thanks guys.
cmdrted, my advice to you if you heed the call from the basement is this. Watkins models are "measure twice, cut once" models. That's been my experience thus far. Scale issues seem to be the biggest thing.
Despite the problems, I'm very pleased with how things have turned out to this point. I've had to make a couple gallons of lemonade along the way, but I'm much wiser for it.
I just printed the M.M. quad bofors and they will look very good. I'll get to work on those tonight.
