Last blog I mentioned I was making a disk sander re-purposed from a dental grinder.
It has been a real battle and I am almost there. Made new plywood disk and mandrel for better balance and to connect to this 1” motor shaft. Base made and she was up and running when the kids came home from school.
Enough talk, here are some pics
This is the dental model grinder used to make smooth and even bases and edges on stone tooth models
Taking it apart….a little brute force and a metal saw used on the outer cowling
Making a ply base and aluminum table recycled from a desk I think
Here is the base dry fit assembled with tape and a pic of the ply disk cut out on my band saw with a circle cutter jig. I changed the rear disk/mandrel from 5” to a 2” diameter as the big one vibrated way too much.
Trying to figure out how this will line up to the disk
Assembles something like this
I have painted the base black and attached a 120 grit paper with sticky backing to the disk. It runs pretty smooth, but I will bolt it down to a portable cart I have. I better make a cowling guard as my son is scared of this thing and I grazed my hand on the outer edge of the disk on try #1. Like to have a RHS guard and a table insert to use a miter gauge. I also want to make two other ply disks so I can quick change grits.
More pics when I get it all together. Darn I still didn’t take a scroll saw pic..next time
