South Bend 9A restoration happening w/pics!!

Finished everything up today save for waiting for for/rev gears to come. If there is anymore gear noise it will be the 80 tooth gear. It looks ok but won't know for sure until my parts come and I can test it.

I just discovered when I put my taper attachment on that I believe it's missing parts. What do you think???? No screw or nut! I don't know anything about taper attachments and would like to know what parts I'm missing? I searched the web and can't find a good diagram of the taper attachment.

It's easy to machine a washer with a spider, you can make them out of wood in a pinch

Easy build spider for small lathe

This is how to build a lathe chuck spider for the beginner with a small import lathe. A spider is used to position thin work out near the end of the jaws so you can face it. I used my Harbor Freight 7x10 to show how. First to give credit. I saw something like this on a post by Mklotz elsewhere...

Machining the thickness of a washer is no trivial task. You will probably be better off creating your own out of bar stock and parting it to the desired width.

Damn good reason to buy a surface grinder...or a pack of shims
 
My for/rev gear assembly arrived today and it "really" quietened the noise down to an acceptable level. I've made a bid for an 80 tooth gear and that will help as well. Also ordered a traverse rack gear as mine is slap wore out and will remove the washers I had put in between the rack and the lathe bed. AND to find out that the taper cross-slide doesn't have the taper assembly screw, which makes the taper assembly useless, puts more salt in my wallet wound! Average cost of a cross-slide screw, for taper attachment, is around $250 and I don't think I'm going there. This has become the million dollar lathe that's only worth around $1800 on a good day. "BUT IT'S ALL MINE!" LoL (Investment $2200 and still counting!)

I got a new cross slide screw (telescoping type) from ebay for ~$70. There are some over on PM that make them.
 
It's not that difficult to single point your own LH 7/16-10 acme screw and attach it to an existing gear and shaft.

I think at this time I don't really need the use of the taper assembly. It would be nice to have it working but I can put it off for another day. I aligned the tailstock to the headstock and had to add about .005" shim between tailstock base and upper.

Maybe for an experienced machinist but not so much for me.
 
As a test I put some 40w oil on the gears and it really made it much quieter. Been looking for a 20T gear for the stud gear on the for/rev tumbler and can't find one. My go to source, eBad, doesn't list any. Still waiting for my offer reply from the seller on a 80T gear.

Update: 8pm Bought an 80T idler gear and be here in a couple of days. Did a couple of test cuts and performed well. Haven't used a mic on the cuts yet to check out consistane on one end vs. other end.
