I needed an edge sander but in my tiny shop I have no room for a large floor model. In ShopNotes #72 there is a drill press powered edge sander that uses 4×36 inch belts. I had some Baltic Birch plywood left over from another project. I bought the bearings from Amazon. The plans call for flanged bearing but at $14 for the lowest priced ones I decided to use flangeless bearings. I got 10 bearings for $26, 3 belts for $10, and miscellaneous fasteners.
The rollers I rough cut on my bandsaw and after gluing I trued up using the router jig in the plans. Instead of gluing the shaft to the rollers I drilled a hole in the side of the rollers and tapped a hole in the shaft. I used a ¼ inch bolt to secure the roller to the shaft. So far it seems to be working.
All of the knobs I made but some are going to be replaced with nicer looking knobs once I get time.
Since the dimensions are lacking for some of the parts I had no idea how far from the apron to the drive shaft it was, so I decided I would just make it as per the plans. As it turns out I had to make a riser for it due to the table on my drill press prevented it from reaching the chuck. The riser is 10×26x5 inches high. I made a cutout that matches the base of the sander so it sits more centered.
In the picture of the riser, I drilled the pilot holes for the screws through both pieces and then drilled a 5/16 inch hole in the base for a screw driver to reach through to drive the screws in. You can also see the shape I made the top part which matches the base of the sander.
The table moves up and down easy and is square to the platen. The Platen is a piece of stainless steel I had. I plan to put a graphite platen pad on to reduce wear on the platen.
It works very well. Though it looks bulky it does not weigh that much. I used screws to connect it to the riser so it can be removed and used as per the plans.
The plans call for a miter fence slot but I have not decided if I am going to cut that. Right now I am going to use it without.
Lining it up with the drill press chuck is not difficult and I have found it really does not need to be clamped to the table but I do it anyway.
Over all it was easy to build and I have only found two edge sanders using 4×36 belts sold. One by Busybee tools and the other from ShopFox. They look identical. The busybee model is $250 and the ShopFox is $350. I do not regret building it and expect to use it a lot.
If anyone has questions about building one I will try to help.
