Bringing this old post of mine back up, still trying to find the correct C/L distance of the two holes!
If anyone happens to currently have a 13" double tumbler gearbox disassembled, it would be great to know the correct C/L distance!

I knew that they're not metal to metal in assembly, but I was trying to get a rough idea of the center-to-center dimension. In the casting's current elongated condition there's a lot of play on the tumbler shaft. Getting it back close to the original dimensions should help in the engagement of...
Never really working with gears that much, all that gear terminology basically just confuses me!
Trying to follow your example given, I'm coming up with 12 for the Diametral pitch, which I don't think is correct? From other remarks about the change gears on a 13" South Bend I believe they are...
I'm currently working on rebuilding a 13" South Bend turret lathe & I've came across a possible issue with the tumbler levers. The castings are worn/elongated where the tumbler shaft runs through the casting.
I'm wondering if there may be an old print/drawing of these castings?
Knowing the...
The other possible problem I can see with a larger pulley, is that it would interfere with removing the pulley assembly with-out removing the V-pulley first.
Yeah I saw that thread, But I don't plan to move the whole lathe downstairs! I'm only moving the manageable parts into the basement to...
That would be hard to do right now since I have the lathe all disassembled. :)
I moved most of the manageable parts inside & down into the basement where I can work on cleaning & refurbishing them during the winter. I'm currently going through the parts & figuring out which ones are worn down...
I was a little confused with my motor at first because of the 6 wires & no motor label/plate.
This article helped me figure it out.

I generally don't have that much of a...
Here's a PDF from Vintage Machinery http://www.vintagemachinery.org/pubs/1617/20852.pdf
It shows the 16" / 13" / 10" / & a conversion kit for the 9"

I recently picked up a 13" SB Turret lathe that has the 3-step cone pulley set-up.
The previous owner changed the v-belts & pulleys to apparently make run it faster than normal?
I want to try to get it back to as close to the original speeds as possible.
According to several manuals I've...
Yeah, I seen one on e-bay listed for something like a grand?
It's kind of like the 509 series Allen Bradley mag starters that list for over $600 new! You can usually find them used for under $50!
I haven't tried to use a VFD on my 2-speed motor, but it sounds kind of difficult anyways. Just...
That terminal pattern looks a lot like the old Delta motors, did it have a couple of those terminal jumper links?
(First pic)
The links are used to switch the Delta motors from 120V to 220V. Pic of a Delta motor plate.
(Second pic)
Chances are the upper right terminal is not used, usually...
I think that may have been somewhat standard with the turret lathes, I also got the dual tool post cross slide base with it.
I hadn't thought about the spokes touching the compound rest when working up close!
That's probably another standard feature of the turret lathes?
I also got the...
Bringing this old post back up, since I recently picked up a 13" South Bend turret lathe & this post/linked videos have helped me figure a few things out:)
In post #46 texasgunsmith stated!
I'm currently at that stage on my disassembly & I was trying to figure that one out!
I lifted the base...
