I made a new drive belt for my 9" Southbend Lathe using 1.0 " wide rein material usually used for making reins for horse and wagon reins. I used E6000 for gluing the ends together, and I hand sanded the ends with a reversed angle. It works great. Good video.

Truth be told, the original glued leather belt lasted 50 years. Very rarely would it slip. Hard to beat the old ways! Thank you for your kind words.

Very cool. Did I miss what kind of glue you used? I have a 1968 SB 10L and want to do the same thing. Questions. 1. Why didn’t you use a wider belt? 2. I’m considering modifying my lathe to a 4.25 HP, 130 VDC variable speed treadmill motor with forward, reverse, electric brake, and electronic lead screw. I’m worried about what belts and pulleys to use on the drive and upper wheels. If you have suggestions I’d appreciate it. Thanks, Paul

Hi Paul, there is an amazon affiliate link in the description for the 3M scotch weld glue I used. 1. This is a very common belt size (cheap) and it has more than enough grip to transfer all of the torque this lathe has to throw at it. 2. If i went that route I would try to retain as much of the original components as possible and modify the treadmill motor to accept a similar stepped pulley. Its hard to suggest something without seeing specifically what you're working worth. I would be happy to respond to a video or a photo if you'd like. On my machine the VFD with the factory 3 phase motor provides more than enough speed control and greatly expanded the range of usable speeds. An electronic leadscrew would be fantastic, I look forward to seeing what you come up with. I considered driving the leadscrew with a stepper motor reading an encoder on the spindle myself, but this lathe has significant sentimental value to me so I opted to keep it in the condition my grandfather gave it to me in.

just wondering if running the belt on the smooth side down would give better grip on the pulleys.....I see most serpentine belt up grades fun with the grooves down???? by the way, that is a Scarf Joint, not a lap joint....sorry, but my old wooden boat woodworking brain kicks in sometimes.....

I appreciate the correction! The smooth side of the belt is very slick and hard- the ribbed side has significantly more grip.

May I ask how long you cut your belt? I bought a lace belt off ebay 1x62.5" but it's too long and worryingly thin. I've maxed out the adjustment, used belt conditioner, and it's still slipping. I have a job to do for a buddy that requires a lot of cutting and it's taking FOREVER! I was considering buying a 1.25x61" but I'd like to see what works for other people before I waist another $50+.

I don't recall the actual length- my suggestion is to buy a belt that is too long and to cut it to length as I did in the video. I can take a measurement for you, but theres a lot of variation in belt length from model to model. This is a 1965 South Bend 10L. I suggest setting the adjustment to the shortest possible adjustment, and then engage the drive lever to move the pulleys apart. Use a garment measuring tape or string at the middle of the pulleys to get a total belt length. If you are using laced belts, you don't need any additional length. If you are using a glued / lap belt, then add a few inches of length to account for the overlap. Lace it /glue it up and mount it, a little slack is preferred at this point. Then adjust the tensioner as necessary to take up the small amount of slop in the belt.

@RocanMotor I called Squirrel Daddy, the company I got the belt from, and they sold me a strip of lace for $10. I have the lacing tool, so I'm going to shorten it. I have to make 2 4" belts for the 18" American, so it'll all work out. I'll just order more than I need from McMaster Carr. I don't prefer the 1" I got because it's so thin. 0.061"

Great video. It's been 5+ months, so is it still holding up after all this time? How often do you run the machine? I have a Logan that I'd like to do the same. Thanks for sharing.
@RocanMotor
Жыл бұрын
It's still holding up fantastic! Normally this would be running nearly daily, but as the shop is still getting set up run time is probably somewhere around 40-50hrs so far. However, I've used this exact method twice before and the belts lasted years without any issue- I stopped working on those machines before the belts quit. It will be obvious if the belt didnt adhere correctly and if it is going to delaminate it will happen early on. Belt tension should be lower than when a leather belt is used simply because the tractive force is so much greater than with a leather belt.

have you ever thought about just cutting a 3 to four in section off then mating the two edges together by laying and glueing the 4 inch section to the top of it? i tried the grind and sand which method but it seemed to allow the thinnest part of the shaved down belt to break over time. if one lays a whole section on top of the two mated ends you’ll have even more material at the joint
@RocanMotor
Жыл бұрын
That's a great suggestion and not something I've experimented with! My only concern would be the belt being overly stiff doubled up at the joint. Perhaps a thinner belt could be used on top, or the ribs of a belt ground off. This method has held up thus far, but only time will long term.

I prefer the synthetic leather belts that can be removed and replaced by simply pulling a pin. In order to remove a rubber belt you have to remove the spindle and undermount dont you? oh I see you're splicing it. Still that's quite a problem should you need to remove the belt.... which isn't often but.
@RocanMotor

I prefer endless belts despite the challenge of replacing them. Pinned belts can sometimes wear the pulley and both pinned or laced belts will sometimes show up in the finish of the work, particularly in softer metals I've found. Definitely lots of benefits to a removable belt though! Thank you for tuning in!

This is a 1965 heavy 10 with an L-00 spindle and taper attachment that was originally delivered to a high school machine shop in New York. I received it in completely unused condition, in the original cosmolene, as it was a spare that was locked away for its entire life. My grandfather was a custodian in the school and tucked it awat when they got rid of the machine program. A shame, but that's how I received almost all of my machines.
