Sorry but as I reassemble my 1937 I'll have a lot of questions. So right now the question is about the worm. What direction should it be installed in? Mine has a key that keys it to the Lead Screw. The key is machined in the worm a bit less than 1/2 the length of the worm. Leaving me to wonder should the key be towards the Headstock or Tailstock when assembled? The worm bushings have detents in them to locate the bushings with the set screws. when the bushings and worm are installed the worm has a lot of end play inside the bushings. I assume this is by design, but thought I'd ask. Should there be shims inside the bushings to take up this slack? I didn't measure but the worm slides for and aft probably 1/4 inch or more. Also how tight of a fit should the worm have to the bushings? Mine are showing some wear, but they are steel as is the worm, no oillight bushing to replace. So I'll again assume that a bit of slop in the worm is acceptable. I checked the cost of the worm. Ouch! I could bite the bullet on the bushings if they need to be "tight." But this looseness appears to be designed into the machine. Oh one more. On the compound and crossfeed dials, under the thumbscrew is supposed to be a "slug." I have 1 and need to replace 1. The 1 that I have looks to be a piece of solid copper maybe brass. I'm thinking copper wire or round stock. That sound right? Or is the "slug" something special so that it don't damage the shaft?
