Can anyone give me any info on this?!?

One of the levers, a sort of shifter fork I'm not a fan of the design. It's just metal on metal. I'm thinking their should be some kind of brass or bronze bushing or something

Assuming both surfaces are steel, bearing bronze (not aluminium bronze) would theoretically provide a better coefficient of friction than steel on steel or brass on steel.

That said, if there's any grease or oil in the mix (which I guess would be likely in a gear box) plus any contaminants (and every gearbox in the kind of conditions we're likely to have, has those), the coefficient of friction can drop quite drastically in all cases.

Using that 'fork' style of part to shift a set of gears along a shaft is a fairly common one. If the shifting is smooth, and you can't see any obvious signs of wear, I'd not worry overly and just enjoy your new lathe.

I tried to post the manual here but it says the file is to large.

@kpschafer

The original file you emailed me was 13.4MB PDF.
I was able to produce a decent looking version that was only 7.1MB, but I could not upload it to this thread; still told it was too large.

I went and checked the "downloads" section since I remember fighting to get a previous manual small enough.
There I had once commented that I could upload 50MB!

I was able to put the original 13.4MB file here:

Thanks,

Well, I've had some time now to sort through all of the tooling and try both chucks out. This is really turning out to be a great machine. Doesn't leak a drop of oil, tight carriage and cross slide, and material that would have made my little 9x19 lathe have a come apart, this machine isn't even phased.
I'm still learning and the carriage control wheel being on the right side of the apron instead of the left is taking some getting used to.
I just recently discovered this machine has a power cross slide also. Figuring that out made my day.
I have all but given up on finding any info on this machine. I have discovered that every single part is individually stamped with the number 36 though. Not sure what the significance is.
I'm going to change the gear oil in the headstock tomorrow and I'll post some pictures of the internals.

I made a chip trey today that slides in and out from the front. Should help keep my shop floors a little bit cleaner, I hope. Just need to get it painted now.

I also took the top off of the headstock today. Not sure who it was now but someone had mentioned wanting to see inside the headstock. I took a picture of the shifter fork I had mentioned when I first got this machine. Appears to just be a cast shifter fork that straddles a gear. Surprised there isn't a Bronze bushing or something. In the last picture I've got my finger and thumb on the area where the cast shifter fork goes, straddling that gear. Seems to work well enough though.
I also noticed that every part on this lathe is stamped #36. Except the headstock. Everything inside the gearbox was stamped #26. Kinda strange.

What weight oil do you all recommend running in the headstock??
