Gents: This is a learning curve thing: We are putting the Shinn wheels and brakes back together, trying to use parts from several sets to get two serviceable ones. Guess what we learned: the original 1938 wheels have a very narrow drum width and corresponding shoe. The 1940 set we're using for parts has shoes about 50% wider as well as a wider drum. Several things come into play here. I would like to stay with the original, narrower, brakes and wheels. The wheel halves are in good condition, and the brake drum area is not cracked or gouged. However, we do not have any of the brake shoes or brake mechanisms. Good for going, but lousy for stopping! We do have excellent, powder coated shoes and brake lever mechanisms for the wider, 1940 brake set-up. We also have one good 1940 wheel and one badly cracked 1940 wheel. Thus, this call for help!
First, if we change over to the 1940, wider drum wheel sets, do we have to do major modifications to the gear/axle to accomodate the wider back of the wheel? Don't think so, but would like to hear from someone who knows about these differences. If we can make the swap to the wider brakes, it seems a good idea - a little more brake area for stopping, beefier area to avoid cracking. This would help with the overhaul, too, since we have all the brake internal parts. All we would need is to locate a complete 1940-style, wider brake wheel.
If, in the interest of total originality, we go with the narrow brake wheels, we have 2 good wheel sets, but need the brake shoes and internal parts - springs, levers, all activation parts. This, too, is a good idea, since brakes are for mag checks only, anyway.
After pondering this over with you, we'll start the hunt for either the 1940 wheel or the 1938 brake internals. Then - all the other stuff goes up for sale/trade! Thanks in advance. Bob Coolbaugh
