I sold my previously made 40cm disc sander for 200$ and made new 30cm for only 30$, including old dish washing maschine motor and velcro sanding discs 2×80 and 1×100 grid. All other is from scraps. Angle gauge is from my bandsaw (I use it also on the router). Possibility to lean working plate up to 45 degree.
The cheapest 30cm disc sander on market here is 300$.
16mm chipboard plate is fixed with four 6mm screws and nuts to 75mm aluminium disc which was a part of the motor shaft (probably used as rubber belt driver). 1/6 HP, 1400 RPM – pretty enough – you can’t stop it with hands or piece of wood against disc sander.

Nice! Very clever… You have to love how useful old washing machine motors are for shop projects.

Nice Ivan!

I’ve been wanting a disc sander for some time. I have an inherited 6” which is basically useless for what I need.

It appears your backing plate is MDF? How has it held up over time?

Looks good Ivan, but has a washing maschine motor enough power?

Ivan, well done. I would like to see a blog or short photo summary on the build. Looks good and I have an old motor left over from a drill press, would be nice to make a dedicated sander like this instead of always sanding on the lathe. How did you mount the plate to the motor? it would also be easier to collect the dust with a disk sander like you have made! thanks for sharing!

I’d also like to know how the disc plate holds up and what you used. A disc sander has been on my to-build list for quite a while.

This is a nice sander. You made it really cheap and it looks very functional.

Excellent work, makes me want to get out and make one instead of buying a new one.
