John, thanks for the info. I only discovered the NJ Brass 2-bays at last year's March meet, then promptly whiffed on buying the one I saw for sale. Now that I know what to look for, I'm sure I'll stumble onto one eventually.
I'm currently working on etch artwork for replacement running boards for the Weaver 4-bay car, to switch from the solid molded plastic version to a see-through pattern. If it goes as planned, I will consider shorter versions for cut-down Weaver cars.
I've been wanting to redo my 1:1 brass gearboxes for a long time. Lucky for me I have some talented friends. Jim Read did all the computer drawings, Terry Van Winkle verified they would work with his printer...and they did so he made a series of very fine resolution prints, destined to become masters. He handed off the new patterns to a shop in NY and they made a low shrink RTV mold. They shot four waxes and used them to cast four test shots in bronze. The bronze always looks mottled but when these are done in yellow brass by Valley Brass & Bronze (David Sciacca) they will look much nicer. So far, I'm very happy with the results.
Thank you for the help Jim & Terry. Obviously I couldn't have done it without you.
