A belt sander thickness sanding attachment for my Makita 3×24 belt sander that attaches in a minute with two bolts into original threaded holes on the side of the sander.
I made this after seeing the post MAFE had done on his big sanding drum which I am unable to locate here in Canada so this is my alternative using my belt sander .
The attachment and cradle is made from Baltic birch plywood and is easily clamped to the bench or clamped in the vise making for easy set up.
To set up the sanding operation I simply slide the sliding part of the attachment down onto the board to be sanded and lock up the sliding part with the two knobs and remove the board by pulling it out toward the rear of the sander.
To start the sanding operation I start the sander and push the board into the rear of the sander and all the way through and pull it out the front .I may have to repeat this to get the desired finish and size .
I attached a safety guard positioned on the front of the cradle to keep my hand away from the belt when pulling the board out of the sander .
Here is some pictures that show and explain the details and the sanding process better then words .
All the attachment parts .

A strip of hickory one inch wide fed through the sander and the measurements on three points along its length are within one thousands ,not bad .
This attachment allows me to sand up to 5 3/4” wide by running the board one way and then reversing the board and run the other half since the attachment is open one one side .
A 1/2” thick board being sanded and a 2” board is no problem . I can switch belts very easy from one grit to another and this will make sanding a lot more precise and quicker .
