Introduction: Dremel Belt Sander Attachment
I made a small sander attachment to be used with my dremel rotary tools.
Sander can be mounted to my diy dremel lathe, or it can be used without it.
Its light weighted and easy to take outside, i like to work outside in the summer, so good mobility is a bonus.
With cordless dremel it really is very mobile.
Step 1: Frame
Structure is very simple
I used 3mm steel plate as a material, it can be made from l-profile bar too, for example.
I just like to re-use scrap... that 3mm plate was only what i found.
I used wheels and bearings from the skateboard, some nuts and bolts.
This one was very cheap, because those nuts and bolts we're the only things i needed to buy.
Step 2: Tightening.. Mounting..
For mounting the dremel and tightening the belt i made a simple part from the polycarbonate.
I took the thread part from the dremel shaping platform attachment, you can take it nearly any dremel attachment if you have one spare.
Video in the last step shows the process.
Step 3: Guide.. Assembly
To keep the belt straight i made a simple tilting mechanism from the steelplate and bolts.
In the steelplate is M8 thread in the middle and M6 threads in the sides, bolt that works as an axle for the upper wheel is placed in the middle of the plate. Plate and side bolts are in the same line with the belt. Tightening or loosening smaller bolts tilts the upper wheel, what guides the belt from side or another. With simple adjusting you can get the belt go straight.
As a drive wheel i mounted the dremel drum sander to the rotaty tool, tightened it to barrel shape. It works very well in that task.
I was suprised how powerfull it is, it was supposed to be for making small things, jewelry etc.. but i have used it with biger tasks too, with no problems.

We have a be nice policy.
