South Bend 9A Where do these parts go?

[Aaron David]

When I was rebuilding my 9B, I ran myself in circles trying to figure out the headstock to bed mounts, and where I put them. Came to realize that the '47 model was the one year to not use these, and the ones I found to "replace" the missing ones not only wouldn't do anything, but were just wasted money. Of course, the manuals I found online did not let me in on this.

All of which to say, be careful when rebuilding these lathes. They were made for a long time, and there are many small variations due to production needs and former owners.

In my case, with SB9, at least some of the bits went whoops - and made it to the floor, and then they somehow bounce sideways!. I spent a while down there, trying to figure what stuff might have dropped, and what was there from previous more casual drops. In the end, I had a monster tidy up. It did result in a few odd nuts and washers left over. I like to have it that the entire count of stuff that comes off, goes back, or is replaced, with zero left over. That does not always happen!

I think the small one sits atop the motor mount.

Not sure what you mean David. On the motor?? The horizontal drive unit??
Edit: Never mind, think I found them!

On my 10K there was a plate similar to the smaller one. The short flange slipped behind the base of the motor and the long part sat on top of the motor. Honestly didn’t know what purpose it served but it was 100% stock.

OMG!
I think Piper & David nailed it! Went back through my pics, and my very 1st pic when I brought in the lathe shows them. I've attached this pic, then an enlarged section of that pic, and finally a few pics later after, clearly showing where the motor shield had been.
Thank you so much guys for helping me figure this out!

Yup! Keep the chips out of the motor winding. I think the one under the spindle is to just help direct them to a tray so you don't have to fish them out from under the foot. My lathe had a replacement motor on it that didn't require the shield. The guy I bought it from had tossed the old 3 phase motor. I would have taken it and put a VFD on it, but oh, well...
Really good work on the restoration. Nothing against the modern machines, but do one has to wonder if they will be restore-able when they are 75 to 100 years old.
I have a really soft spot for old iron.

Thanks for posting back with the answer and some photos.
I have been following this thread, but had never seen those two chip shields before.
Maybe I should make some for my SB9.....

The parts do not go to a bench top 9A.

Here are a couple pics showing the two items in their final location.
The smaller piece under the headstock is held in position by spring tension. The small 90 degree bend is captured by the headstock clamp, and the notches on the sides hold it with spring tension against the web of the bed. This keeps chips from getting all the way down into the foot of the bed.
Thanks to all for the help!
