Update from thread http://www.mtfca.com/discus/messages/29/47187.html?1203449539

I did make a change that I did not foresee on the first one I did (the one I posted pictures of). After some thought, I realized the purpose of the steel sleeve was not so much as a bushing but rather there to provide a continuous smooth radial surface. Since the keyways and gear teeth are broached farther up the pinion shaft than is actually used (see picture on original post), that only leaves about .50" of smooth linear surface around the shaft. These grooves would wear a brass bushing prematurely. Therefore I left the steel sleeve in place and machined it to a wall thickness of approximately .060" and the flange to .050" then polished both. The brass bushing also has a wall thickness of approximately the same, and the flange thickness as well. This way, we did away with the need for a steel shim washer, and give a continous smooth surface to run against the brass.

Also, the stem originally used on the fixture (faux gear case) was removed and the fixture held in a 4-jaw chuck. The reason for this is, apparently, the case covers were not originally held to any strict tolerance when machined. Each cover placed on the fixture was different as far as the bore being centered. In a 4-jaw, each cover can be indicated and the bore centered.

Here are some pictures of two that I did for a forum member. They are finished other than a quick honing to running clearance (and of course a quick bath in the parts washer).

I want to thank Ray for getting my steering cover fixed. Much much nicer then before. The wheel turns nice and no slop.
Thanks for the time taken to do this.

Thanks fellas for the opportunity to help you out. I enjoy being a small part of your success keeping these cars on the road and a pleasure to drive.

Hopefully John will be as pleased with his door latch as soon as I get that finished!

Thanks again
Ray
