I will be building a 10" wide surface sander mostly from pieces and materials in my shop. I have checked several different machines and down loaded the owner manuals to get some ideas. It will be open ended so you can sand 20" wide by turning the part around and running it through again.
I have a 3/4hp 1725 rpm motor that will be direct coupled to the drum. This power unit will be raised and lowered by a hand crank and using linear bearings.
I am making this as I go long so no drawings or sketches.
First the drum assembly
I have a piece of 3" 40 schedule steel pipe that I will use for the drum and two round steel disks. The disks were something I picked up out of the trash many years back and thought I can use them for something someday. The shaft is 30mm because I have the shaft and some bearings to fit. What I have in the shop will determine how it ends up. I will need to buy some materials and parts but I like to use what I have.
I bored the disks to fit the shaft and added a set screw in each. I turned down the outside of the disks to just fit inside the drum and welded them in place.
Next to the lathe to true up the outside of the drum.
Drum completed and inside painted.
The bearing retainers were turned from some mystery steel chunks out of the scrap bin.
Here they are painted with the bearings fitted and the holes drilled and tapped.
And on the drum.
That's all for now.
Thanks for looking
