Drill Press Disc Sander





Introduction: Drill Press Disc Sander

About: Hi I'm Kriss! I’m a 20-something that likes to build tools, jigs, and other random contraptions with wood.

Transform a drill press into a disc sander with a few simple attachments.

Step 1: Prototype

Threw this together with scraps of wood and a few clamps. Proof of concept... check!

Step 2: Design

The disc sander is drafted in Fusion 360. This way I can refine the shape while quickly visualizing different designs.

Step 3: Ripping, Sanding, Cross-cutting

Everything is made from a sheet of 3/4" baltic birch plywood.

Step 4: Assemble the Base

3 pieces of material form the base. They're held together with drywall screws.

Tip: A workbench makes a fantastic 90 degree clamp!

Step 5: Make the Sanding Pad

Cut a 9" circle out of some more 3/4" plywood to support the sanding pad.

Step 6: How the Sanding Pad Will Spin

Drill press -> right angle adapter -> 2" screwdriver bit -> 1/2" set screw -> sandpaper (and a lazy Susan bearing holds the sanding disc in place).

Sandpaper (10 pack) - http://amzn.to/1SFO82g

Lazy Susan Bearing (the 9" inch one) - http://bit.ly/1SIdMQz

Step 7: Assemble It

Connect one side of the lazy Susan to the base, and the other side to the sanding pad.

Step 8: Stick Sandpaper

9" adhesive backed pad of 80 grit paper.

Step 9: Attach the Sanding Platform

The finishing touch is to screw on the sanding platform. A few more drywall screws.

Step 10: Lubricate the Bearing

I used silicone spray here, but apparently that's not good for bearings. If you do this, use machine oil.

Step 11: Attach to the Drill Press

I tilt the drill press table 90 degrees, and secure the disc sander with a clamp from the side.

Step 12: It's Sanding!

This project worked much better than I expected.

HIGH FIVE for reading!

May I ask how you removed everything from the thumbnail, And made a red background instead? Is that some kind of Photoshop trick?

its easy to remove the back ground in Photoshop ...if you have it. Id use the pen tool, I find its much easier to follow the shape of the item your trying to get off the back ground and more forgiving than the eraser tool...and you can actively zoom in and out while using the pen tool and not mess anything up so if you zoom way in you can really follow intricate shapes and patterns then zoom out and turn it into a "Selection" and just hit "copy" and then paste it onto a new back ground of your choice.

If you dont have Photoshop try downloading the gimp..its probably the closest thing to Photoshop you'll find and its free! and it does most of what Photoshop can do so if you know how to do anything in Photoshop you'll be able to figure it out in the gimp. lol

Do you mean the thumbnail of the video, or the thumbnail of the instructables post?

Removing the background of the video is brute-force erasing it in photoshop.

To get the text out the instructables thumbnail... I probably need to create an instructable for that. Let me know!

I like it. One different approach might be to have the disk able to spin, and have a small wheel chucked into the drill turning against the disk with friction. Saves having to find a right angle gearbox that can take all the tourque.

Interesting idea, I can see where a salvaged gearbox from a defunct angle grinder would also find a new home too.

Awesome idea! I know I have one somewhere buried in the shop. Let the search begin.

Looks like you did a great job. Saved a ton of money too.

Hmm. I'll try this, but I'll modify the angle adapter with a line point.

This great idea !!!

Awesome way of thinking, great instuctable :)
