Making a DIY 2x72' Belt Grinder from Treadmill Parts

In this video a 2 x 72 belt grinder is made from treadmill parts. This type of belt grinder is very popular with knife makers because it can remove large amounts of metal very quickly. However, it can be very useful for many other metal and woodworking projects.

I have watched approximately 20 builds of belt grinders, the detail and plans provided are great! Best video I have come across to date

at about 11 minutes in I realized your primary skill is in electronics. You really did a good job on the custom controls box. It's clearly not your first time. The metal fab part was good but not your strong suit. lol Great job! It looks great! I love this video because I'm weak in the electronics side and strong in the fab side. I enjoyed seeing how you did your controls box.

Very nice job, looks great, and it's yours to use, and save time building more stuff! Thanks for sharing.

Fail early and often. Failure is an excellent teacher. Cool build. Thanks for documenting and sharing.

liked the vid.enjoyed the music. thanks. it takes a lot of different folks to make the world work.

[SuperGrover]

Very very nice work, and I like that you pointed out the issues, I had similar problems when I built mine. The music on the other hand, watching first thing in the morning with a hangover, holy crap! :D

I like your design on the belt adjustment wheel. As well as the compression spring being integrated is cleaner and more compact.

[Tinkering]

Pretty smart stretching out the spring!

FYI: Serpentine belt idler pulleys, (Dodge/Plymouth are best because they have a flange), and a belt tensioner are great for making 1 x 72" or 1 x 42" belt sanders. Because of the flanges on the pulleys, you don't need an alignment mechanism. The idlers have sealed ball bearings.

You can use a smooth drive pulley from serpentines as a drive pulley on the motor. Use someone that non-slip adhesive tape for traction.

Thanks for sharing your difficulties! Being honest is much more important than building a perfect Belt Grinder! ;)

[dariostino]

Nice build, and good on you for pointing out the glitches!!

[whatme]

[defendthebelt]

[mattbowie]

Very well done. Great video an wonderful craftsmanship

[heru-deshet]

This is one of the sweetest builds I've seen, brother. The satisfaction value is priceless.

[joefriday]

Excellent build. I was going to comment on maybe using different music, but then after seeing you, I decided using anything but metal would be inappropriate. Thanks for sharing and I was impressed by the cleanliness of your drill press table!

[bicivelo]

Awesome video. Thanks for sharing your experience and ways to improve on it. Great build!
