    13" South Bend lathe Quick Change Tumbler Lever Question

    Ted reconfirmed confirmed the 2.166" C/L distance, his measurement was 2.167" The local machinist I had do the work for me was also able to come up with a 5-degree angle between the plunger C/L & the 1/2 hole for the tumbler gear shaft. The machinist made a jig to locate the arm for boring it...

    13" Lathe Large V-Belt Pulley Size

    It's probably a good thing I pulled the base out & put it up on the stand to work on it. The pulleys & belts I used are size "B" which should give me a little extra grip! With the larger width "B" pulleys I also ran into a slight clearance problem since the pulley's & belts were originally...

    South Bend Serial# Card Info.

    Having worked in various machine shops throughout the years, I've probably been part of the madness.:rolleyes5: I have seen & done some unusual modifications to keep machines up & running. The closest visual match I've came up with on my motor, is this one I seen on e-bay that came from a 16"...

    South Bend Serial# Card Info.

    Thanks for the info. all I had come up with so far was that the 2HP -1HP two-speed motors originally only came with the 14-1/2 & up lathes. Thanks again! That motor controls pdf. also answered another question I had regarding the two-speed motor controllers. I've seen a couple pictures of...

    South Bend Serial# Card Info.

    I figured that was the case! The drum switch that was on it was a Cutter Hammer 9441H18A & it was wired to a size 00 Square D reversing starter & just to the low-speed windings. The motor & drive pulleys had been changed, I assume to offset the lower motor speed? Doug

    13" Lathe Large V-Belt Pulley Size

    Here's an update to my lathe pulley issues! I had to put this project on hold for most of the summer because of lower back problems. After about 8-weeks of physical-therapy, I finally realize what I can & can't do any longer. I had the bed, base, legs, & chip-tray already in place where I...

    South Bend Serial# Card Info.

    That confirms my original suspicion that the motor was replaced. I figured the motor may have been a replacement, since it's larger than what would have originally been offered with the 13" lathes. The motor that came with the lathe is a 3-phase two-speed dual-winding motor. There was no ID...

    South Bend Serial# Card Info.

    Yeah, I realize that now! I already knew the approximant date, so it's not really too much information for the $25. The unit code numbers (if there's a way to cross-reference them) may help if there happens to be several parts used on other size lathes? Doug

    South Bend Serial# Card Info.

    I just ordered a serial# card from Grizzly for a 13" turret lathe that I'm in the process of rebuilding. I was hoping to get a little more information/history on the original shop that bought it. Unfortunately, all the serial card shows is that it was sold to "Brown 64-6" and no city or state...

    13" South Bend lathe Quick Change Tumbler Lever Question

    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! Ted sending you an email. Doug

    13" South Bend lathe Quick Change Tumbler Lever Question

    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...

    13" South Bend lathe Quick Change Tumbler Lever Question

    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...

    13" South Bend lathe Quick Change Tumbler Lever Question

    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...

    13" Lathe Large V-Belt Pulley Size

    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...

    13" Lathe Large V-Belt Pulley Size

    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...

    Looking for 2 Speed Motor for 13" SB

    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. https://www.hollandindustrial.com/wp-content/uploads/sites/197/2015/12/Identify-Unmarked-Leads-6-and-9-Lead-Motors.pdf I generally don't have that much of a...

    13" Lathe Large V-Belt Pulley Size

    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" Doug

    13" Lathe Large V-Belt Pulley Size

    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...

    Looking for 2 Speed Motor for 13" SB

    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...

    Looking for 2 Speed Motor for 13" SB

    South Bend also used a Furnas JED4 drum switch for the dual winding 3PH. motors. I've been trying to find one, but they're hard to find. Doug
