OLD LATHE
RussellT:
Well, looking at the enlarged logo the teeth on the outside make it nothing like a Mercedes logo.
However Google finds a couple of reference to Sociedade Technica Bremensis Ltda with an address in Rio. One of them is about elimination of German resources for war suggesting it's a German company so I'd guess it was imported from Germany.
This link https://teses.usp.br/teses/disponiveis/16/16134/tde-01092016-154117/pt-br.php is quite specific about it being a Brazilian/German company.

Celsoari after all the things we have seen you make I'm sure that bashing up a sheet metal gear cover would be no problem. If you want some help with a threading chart let us know what pitch the leadscrew is and what tooth counts you have on the gears that are with it. The rest will be easy to work out.

Thank you Mr. Pete. The lead screw has 8 teeth per inch, and the spindle gear has 26 teeth.
I found a restorer who makes the plate threading chart (as in the example of the attached photo), I just need a photo or drawing to model.
if anyone has can send.
(sorry my english is not very good, we speak portuguese here in Brazil)

You're doing fine with your English Celso.
If it's a 8tpi screw it's less likely to be of German origin.
What tooth counts do all your other gears have?

Ah, now you're talking. You can do metric threads with the 127 tooth gear.
One more question. There is a gear behind the one marked in green. Should be 26 teeth. Can you confirm this?
