DIY Belt Grinder

In this project, we made a small belt grinder (belt sander). For that, we used an old 1.5 hp electric motor (we recommend a 2 HP motor or higher), a 70x5 cm belt sander, some off-the-shelf bearings, and a few metal pieces.
We used Autodesk Inventor to create the 3D model and the drawings. You can modify the design to suit your needs.
We share the PDF drawings and Inventor files here and hope they will be useful for you and your workshop.

How do I get the plans please

[@TheTransformerChannel]

Hi Steven, you would be able to download them from the links in description. Please let me know if you have any issues. More than happy to help 😊

[@antoinedeoliveirarosas1594]

I wanted to thank this gentleman for putting up a free PDF, I respect that and thank you. A fan from France

[@martintiney1770]

ive been looking for a simple tension / tracing design for ages ,with a little modification this will be perfect thank you

[@martystratton5818]

Great millwork! Especially for not using a mill! Great job on repurposing a motor.

[@fredcheung1940]

That's a great project. Your use of heavy steel plate in its construction will add to its accuracy, rigidity, and longevity.

[@HpDonChhangte]

Love it..❤ Kinda simple, without much meterials. I'm gonna copy exactly as you did. Thank you for sharing.

[@luiscarlossuarezmarquez264]

Brilliant work and thanks for sharing your schematics in the video.

Great project!! Thank you for sharing. I think I might try to build one too!!

Awesome, we would love to see your results 👍

[@specdel]

Beautifully compact machine - could be stored under the bench when not in use, big plus for a small workshop. Well done, from a new subscriber.

[@TheTransformerChannel]

Awesome, thank you and welcome to my channel

[@user-jc1zp7ub6c]

I made a similar grinder out of 6 and 20mm plywood using only a desktop CNC machine, screws and glue. There is only one polished stainless steel plate in the entire machine. The machine has been working great for 2 years now.

[@claytonsimplot9554]

You did great work with what you have. I believe a Bridgeport would be all you need. Any special attachments I think you would have no problems making. Headstock and tailstock for o.d. grinding ,a magnetic table for surface grinding and an indexer for squares ,spirals or flutes. I think you could do it. I would try it but I don't have any room or machines,

WoW. I created one, along these lines a few years ago. 2 x 42 inch one. Used a skateboard wheel ( with bearings ) as the top tracking. I put a slight convex curve in the face ( as it turned on a fast drill - with file ) to keep belt centred. As well, did the same for the 5.5 inch 2 pieces of 1 inch plywood, glued / screwed together, for the motor drive. Same convex curve, too. I used a 2 inch half-moon, round wood rasp, for the tracking on the skateboard wheel, on a welded - on shaft. VERY GOOD grip, to adjust it. Motor - 1 hp 3450 rpm. So, using the 2 inch tracking wheel, the belt probly goes over 5500 rpm. TAKES OFF metal really fast, using 80 grit belt. Anyway.....good luck, all. (salvaged magnets, from microwaves to catch the filings, on the bottom) THE world, is full of creative / inventive persons. BE / WORK / PLAY ENJOY LIFE SAFELY - wear a toque over your ears, ear protection, eye protection, steel toed boots, maybe a leather smock, when welding / grinding in shop. I've burnt enuff holes in clothes........so have you. Take care, Mr Xformer.......thanks, for the on-going education, for those whose MINDS are open, to NEW IDEAS.

[@LexterLS400]

This vid is really great, i do miss some details that keep me wondering how to copy that ? The main wheel ... what is its exact size and the French dude said: A bigger wheel will cost you torque. Did you change the size of the first wheel ? And what size was the second wheel and what size did you adapt it to ? How do you know that your machine runs at 1500 rpm ? What is the size of those bearings you use for the guide roller ? How many kilos does your machine weight ? How would someone adjust the speed to prevent the belt will melt ? Or that is stops because it is not strong enough ? What program is used to makje the design blueprint ? How many lanquages do you speak ? I am still fighting the main base plate i am trying to make the perfect metal mall to cut future plates with the plasma cutter.

[@reaper060670]

Mr Transformer.. U have got some brilliant metalwork skills my brother.. WOW. I was going to buy one of those Motors on VEVOR for 170 euros but u found one and made it good again. Was the motor working or did u need to fix it to run again?? What i built is magnificent to be honest with u. I salute u Sir. That's a great piece u built there. Cedit to ya man.. I just found ur channel so I sub'd and shared, liked all that good stuff..

[@jorgesantos4646]

Show de projeto, o único ponto que achei que poderia ser melhorado seria alongar mais o eixo para afastar a cinta do motor porque ficou parecendo que limita um pouco os movimentos ao trabalhar.

[@jacobyunderhill3999]

Hmm. Not crazy about the music. Also, your "wheels" should have a crown rather than being flat, as it will improve tracking. Other than that, cool build. And very nice to share your plans!
