Belt sander

Since I started making knives I wanted a belt sander. The nice 2x72 models that everyone seems to use are too big for my shop, expensive, and hard to obtain where I live.
So I made my own :smiley:

It is very compact and works with 1.5x38 belts. It has belt tensioning and tracking, adjustable speed with a vfd, a little work table with adjustable angle and exchangeable arms so I could also mount a contact wheel.

It works better than I expected, except for some minor vibrations from the drive wheel. I’ll replace that with a better part in the future.
It speeds up my work by so much, just cutting and filing this knife blank would have taken me ~2 days before, now it took me about an hour :slight_smile:

That’s great! I’ve got a cheap HF belt sander and have always wanted to build one so I can chuck that cheap sucker in the trash. :slight_smile:

That is awesome.

This thing is a beaut! Nice work

Very nice work! In the highest compliment this can be it looks nicer than some of the tools Mathias Wandel has made.

That is really nice… :slight_smile:

Wow, thank you very much for that compliment!
To be fair I could never build a machine like Mathias Wandel without a CNC :sweat_smile:
But I definitely thought of him when I built it :slight_smile:

Great job, I love how compact it is. What did you use for pulleys?

The large drive wheel is cut from multiple layers of plywood, then i mounted it on the motor and turned it so it would be as round as possible. This didn’t work as well for the smaller wheels, so I 3d printed them with PETG filament, since this should hold up better to high temperatures. So far they hold up pretty well :slight_smile:
