nachman, that's amazing. If I tried to solder something that small, I'd end up with a poling blob instead of a pocket!
doctorwayne, your variation on nachoman's theme is a good idea - I'll have to experiment with that.
nkp and brakie, thanks for the pointer to Precision Scale (and also via Walthers). I actually have their catalog, but didn't think to use it... I'll look into Grandt line and Cal Scale as well. Are there any other detail firms that are worth looking into?
