Been using a lathemounted disc sander for a couple of years now, but as I have started to use the lathe more and more for other stuff I figured that I had to make a dedicated sander.
The lathe sander worked well but the one thing I was missing the most was dust extraction and the hassle of changing the grit from “shaping-sanding” to fine sanding.
From that came the idea of a double disc sander, and due to size and configuration of workshop I had to make it side by side.
Another thing that had to be custom made was the sanding table. I wanted it to be able to tilt, but it also had to stow away, when not in use, because otherwise I would end up with brused ribs every time I had to pass the location of the sander.
My bench where it sits is 40cm deep, and this is also the depth of my sander with the table folded up, so it is out of the way.
It has 2×12” discs with 60 and 120 grit sandpaper spinning @ 1350rpm, tilting table and a dust collection port.
Frame is made from 24mm plastic laminated birch plywood , with some 9mm birch ply and oak hardwood where needed.
The motor is a 550w salvaged 3 phase motor running on single phase and a cap.
Drive shafts are 25mm with pillowblock bearings. (salvaged)
Pulleys are turned from 20mm birch plywood on a wood lathe.
V-belts are O-type for sewing machines of ebay.
Sanding discs are from 20mm plastic laminated mdf and is mounted to 40mm thick oak “faceplates”
The sandpaper is velcro backed for easy removal.
Here is an atached youtube video of it in use showing the stow away table (did not have any stills)
