Sanding Jig for long slender parts

While I do have a versatile, nicely built Sander/Grinder (photo 4), sanding the longer edges of some parts remains a bit of a challenge at times. So, I decided to try a low-tech approach by making a simple holder for the same 1” x 42” sanding belts that I use on the Sander/Grinder.
I simply cut a piece of MDF shelving (with laminate on both sides) to about 20½” x 5”, with one end cut at 90° across, and the opposite end cut at approximately 80° (photo 2). These dimensions allow me to slide one of the sanding belts onto the board so that it tightens as I move it towards the rear (longer) edge. As the belt eventually becomes worn, it’s a simple matter of moving it forwards to loosen it, re-position it to a fresh length, and re-tighten it as before. Changing belts for different grits is just as easy.
Since this was a quick build, I did not add a 90° fence to ensure square edges, but a pair of clamps and a guide block should take care of that if needed. The laminated MDF maintains a suitably flat surface for this purpose, and I usually clamp it to the top of my tablesaw (photo 1) to maintain stability during use.
Happy sanding.

Thanks for the comments guys.
I should add that this jig is also great for putting a specific angle on the edge of a board, or for rounding over an edge uniformly along its length.

Good sanding setup and will get things flat for you could use a piece of corresponding wedge shaped dowel to tighten the belt .
I have a larger version of this and use belts from a thickness sander and love it it for flattening all kinds of things .

John. Really good idea. Sanding is always a challenge and any outside of the Box thinking is always welcome. Thank you for sharing the idea.

Thanks to all for the additional comments.
I’ll add 2 other points that I should have included earlier . . .
1. Since the back side of the jig has the belt exposed, it will tend to keep the jig from sliding as you use it, but I make sure NOT to use it on a surface that I don’t want any marks on.
2. Once you feel that the working area of the belt needs refreshing, you can simply flip the jig over instead of loosening and re-tightening the belt.
Have a great day.
