Thanks for sharing the idea to make new belts! I hope it is a durable solution... the SL type Unimat uses a different motor, also completely closed. Indeed pressed air is good to prevent problems.
Thank you, from the Great Pacific NorthWET, Oregon Division. I do not ~own~ a Unimat, but I do follow most every "small lathe channel" that I can find. Your Very controlled voice reminds me of my days in Avionics Radio Repair, and I deeply appreciated your comment on your qualifications to do motor repair. I have left behind ANY & Every utube channel that I see doing Unsafe Work, AND leave comments on WHY! Hopefully NEW machinists, will be thinking on that. at 73 years of age, I have dropped from 19" Diameter Swings with Seven foot long beds, to my Proxxon M150 that can do 4" long! I use the Proxxon M-70 milling machine, and design my own cutting tools from 7 1/4" carbide tipped (new) saw blades: 24 carbide tools, for approximately $12.00 U.S.D. I have not started a Utube channel, but imagine milling "a bar" length as needed, and either a left hand, or right hand Carbide to cut with! Yours, From up above the equator, Philip, AKA, the madsighntist.
Thanks Philip. I really appreciate you taking the time to comment. I'm in the early learning stage as far as making videos is concerned. Truth is, I hate seeing myself on screen and am not keen on hearing my own voice either. Putting words on the screen seemed the only solution but then I found there was too much I wanted to say here. BTW - I'll be 72 this year so we're around the same age. Wishing you all the best for the new year. PS. You're well ahead of me in being able to design and build your own carbide-tipped cutting tools! That would certainly ne worth seeing.
Hi there. It is a normal right-hand thread. (Turn the pulley anticlockwise to loosen it while one of your chuck adjusting pins is through the main spindle and holding it to stop that from turning.) I just loosened mine to double check because I haven't had it off for a while (and my memory is terrible). Mine was tight but I managed to undo it simply with a firm handgrip on the pulley sheaves. You may need to use a rag on your sheaves to stop them cutting into your skin if yours is tighter than mine was. Good luck - Tom
Just discovered this... If that scooter motor doesn't work out, that plastic plate appears to be a great candidate for a 3d printed replacement part. Just need to get a good dimensional diagram.
It's worked out well. I'm still using my Unimat 3 regularly and all the time I have it powered by the scooter motor (so I'm now just holding my original Unimat 3 motor as a spare). 😊
That headstock pulley should easily unscrew off the headstock spindle. Just use one hand on that pulley and one of the two little steel rods you use to adjust the jaws on the 3-jaw chuck to hold the spindle from moving.
Thanks. I'm often disappointed with TH-cam video quality and I've never been sure how many countries are affected by it. I wasn't even aware I could alter it at my end until now. 😊
Thank you. Unfortunately you won't find many new videos appearing. I'm still enthusiastically working on projects but it takes me a tremendous amount of time to do a video and other things are much more pressing at the moment. 😊

They're certainly far more durable than the original rubber belts. 😊

Thanks for taking the time to make this informative video!
I'm glad you found it useful. It makes doing it feel worthwhile. 😊
Trying to loosen the pulley and wondering if it is threaded right or left?

Clear and complete. Thanks.
Thanks for all the drive belt tips! How does one replace the power drive belt? Ir wont go over the headstock pulley

Thank you!
FYI: I found I had to increase my video quality to 720p in order to read the information on screen. Hope this helps others watching.

Just found your channel and Subscribed. Very nice lathe
