Sanding edges on a 12” disc sander only leave you with 6” of sanding surface before you move into dangerous territorium passing over the right side of the spinning disk going upwards.

Anyone who has ever tried this know what I am talking about.

So I decided I wanted to make an edgesander, with a couple of addons.

The sander is built from 24mm Plywood with high pressure laminate on both sides, and some 18mm mdf with the same surface.

Main structures are from plywood and table and dustcover from mdf (I ran out of ply)

Motor is 3/4 hp, and is underpowered. It will be replaced with a 1.5 hp.

Instead of putting the table at a skew, I decided to try to make it oscillating

The oscillation is provided by a windshield wiper motor.

The belt is 82” x 6”.

All the pulleys are made from 20mm plywood on the lathe.
The belt tension comes from a compression spring, which is compressed with the lever on the top to release belt tenion to replace it.

Drums are made from ABS pipe with plywood plugs in the ends.

Table is adjustable to use different parts of the sanding belt.

I made the shaft on the drive side of the sander long enough to add a 1 1/2” sanding drum at the top, and the dust cover suits as a table for it.
The main drive drum is 110mm and serves as a drumsander for larger inside curves.

The table for this drum is also adjustable in height.

I built a hinged free rolling drum to be able to track the belt, but adjusting the position on the motor for the oscillation up or down serves as tracking adjustment enough. (this make it tilt more or less front to back, adjusting the belt position on the drum)

You can see a build video of it on my Youtube Channel

I am very happy with it and hope I will get a lot of good use from it.

Thought I had seen this before, it was your video a month or so ago. Great work. Good to know about the motor. I’d like to build one and have several motors from 1/3 hp to 2 hp, guess I’ll use the bigger motor.

That is really impressive! You are a mechanical genius! I assume the windshield wiper motor for oscillation is 12v; how do you power it?

Great Build! I gotta learn to make one of those. Can’t afford a commercial one. Good Job. Thanks for posting.

That’s an amazing creation, fantastic work. Never seen an edge sander made from wood before, and it’s even oscillating. The turned pulleys are a neat idea, I’ll have to try that someday.

What a fantastic build. Excellent planning and engineering skills applied to this project.

Such machines are very valuable for the reason you mention in your post. They are of course also very expensive to buy commercially.

I am sure if looked after it will last for years and provide valuable service to your shop.

Is it all your own design or did you come across a plan?

Either way, a well executed project, top marks.
