Just how small is a baby lathe?

[Phillip Kelley]

Well, pretty small. Thanks again for all of the input! Attached are two pictures of this little nightmare. I was not really aware that the v-belts were sized by mm so; I guess I need a 4M43.
Can anyone else help with a source?

Now that is cool. I guess a baby lathe is just what they say it is.

Phil, I have used beltsforanything.com with good results in the past. Give them a call. Good service,reasonable,and close to you. They are in Lafayette,LA. Hope this helps.

That doesn't look like a v-belt to me, it looks like a timing belt. Are there grooves or teeth on the pulleys that the knobs on the belt fit into. Further supporting this is I cannot find a single mention of a 4mm wide v-belt anywhere. However, a T2.5 timing belt is 4mm or 0.157" wide and I can find it ready made in 420mm lengths. I can't find one that is 430mm. Is there enough adjustment in the lathe to allow you to use a belt that is about 1/2" shorter. There should be some adjustment to tension the belt.

If you don't find an exact replacement, I would go to either a sewing machine repair shop or a vacuum cleaner repair shop. One might have a belt that would stretch to fit.

Google up Grizzly and call the parts Dept. One of my lathes looks just like it only a different brand.
Hope this helps

I saw one that was powered by a Dremel and thought it was small, yours takes some beating, very nice.

No grooves on the pulleys (sheaves) never have learned the difference, I haven't disassembled it yet, but there doesn't seem to be any tension adjustment. Where can I find this T2.5 belt x 420mm?
Thanks for the input!!!:biggrin::musical-note:

Walmart!

Thanks for the idea, I went to Wal Mart yesterday thinking I might find
one of those rubber, round drive belts that I could stretch around the pulleys....too short & it might put too much tension on the bearings..??

The ol' feller that I bought it from "met a stranger & took him in". After doing some searching I discovered that the model is discontinued and sold for LESS than I paid him for it! I was feeling pretty bad about it until I read the title verse for Chapter 2 of The Duck Commander Book! From the
NIV: "Bear with each other and forgive one another if any of you have a grievance against someone. Forgive as the Lord forgave you". Colossians 3: 12 & 13

I use small belts like the one pictured. Try Powering Progress Gates Rubber Co. is one of the largest belt mfg. in the world.. Search their site for 3M500 (this is the belt I use most of the time in my design work, 3mm X 500mm) that will get you to the small belt listings. The ridges on the top of the belt in your picture, look like the ones on all the belts I use.

Hope This helps.

The timing belts I found before won't work.

Using his information I found some better belts. I have been entirely unable to find a 4mm wide belt in anything other than a timing configuration, unless you want to custom order it. However, I did find some 3mm and 5mm wide v-belts in 425mm and 437mm lengths. They are Gates polyflex belts and the part numbers are 3M425, 3M437, 5M425 and 5M437.

This supplier is the only one I could find that didn't have a minimum order quantity or price. Shipping is more than the belt, but is still cheaper overall than anyone else I found. Just type one of the part numbers into the search field at the top of the page and hit enter:
https://www.americanmademro.com/shop/pc/viewcategories.asp

According to Gates website the angle of both belts is 60deg. I am betting that your 4mm belt was the same angle. If that is the case the only difference I see is that the 3mm wide belt will ride lower in the sheeves and the 5mm belt will ride higer in the sheeves. If that is correct if you use a 3mm belt use one that is slightly shorter ie 425mm and if you use a 5mm belt use one that is slightly longer ie 437mm. If I was going to order one I would order the 5M437 to see if it works and then go from there. However, since shipping is the most expensive part of the cost I would probably order a couple different ones at the same time.

I have never used belts like this so I could be wrong in my assumptions, I have just been researching these online. If I am wrong somebody please correct me.

Hope this helps.

I got my Griz Metal lathe belt from here. Looks a lot like yours. Just see if they have your size.

This is getting better than I hoped the results would be! Thanks for the research! Maybe I can pay it forward sometime...
