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).

ALL THE STUFFS

Drill Press - http://amzn.to/21pGQSL

Right Angle Drill Adapter - http://amzn.to/1SIdIAt

Screwdriver Bit (6 pack) - http://amzn.to/1Y2M4Sr

1/2" Set Screw (8 pack) - http://amzn.to/23iEJQ0

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.

<p>Hi, I've added your project to <em style="">&quot;</em><em style="">The Ultimate Collection of DIY Workshop Tools</em><em style="">&quot; </em>Collection</p><p>Here is the link If you are interested:</p><p><a href="https://www.instructables.com/id/The-Ultimate-Collection-of-DIY-Workshop-Tools/">https://www.instructables.com/id/The-Ultimate-Colle...</a></p>
Awesome post, I'm a big fan of your works. I've been a subscriber on YouTube for a while and decided to search you on here and here you are! I just finished building my own and, aside from it being assembled from complete garbage, scrap wood. It was put together as fast as I possibly could do it and it is extremely &quot;ghetto&quot;. surprisingly, it works fantastic so far! I need a disc sander for a project and funds are very tight right now so, this was the perfect post/project for me today. thank you so much and I hope to collaborate with you in the very near future. I'm slowly but surely building a shop and studio so, I can produce my very own woodworking channel on YouTube and wherever else I can acquire an audience to turn profit to care for my family and myself. keep it up bro, hope this finds you and your loved ones, healthy and wealthy! best wishes!<br><br>-Bill<br><br>c/o &quot;incredabill woodworks&quot;
<p>Cool idea ;)</p>
<p>May I ask how you removed everything from the thumbnail, And made a red background instead? Is that some kind of Photoshop trick?</p>
<p>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 &quot;Selection&quot; and just hit &quot;copy&quot; and then paste it onto a new back ground of your choice. </p><p> 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 </p>
<p>Do you mean the thumbnail of the video, or the thumbnail of the instructables post?</p><p>Removing the background of the video is brute-force erasing it in photoshop.</p><p>To get the text out the instructables thumbnail... I probably need to create an instructable for that. Let me know!</p>
<p>Both...</p><p>Oh...</p>
<p>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. </p>
<p>For big jobs I had modified a lathe using a bowl turning plate. But I have limited space and it's a pain to set up. I made a smaller version of your idea. I already had everything I needed in the junk pile. I did add a bearing at the base of the sander since my 90 deg adapter was kinda' crappy. It is an old harbor freight one out of production. This works well enough for the light work, mostly r/c hobby applications. Thanks for the idea. I wonder if I could make a small belt sander.......</p>
<p>Interesting idea, I can see where a salvaged gearbox from a defunct angle grinder would also find a new home too.</p>
Awesome idea! I know I have one somewhere buried in the shop. Let the search begin.
<p>:D You know it! Thanks!!</p>
<p>Looks like you did a great job. Saved a ton of money too.</p>
Lube*
Hmm. I'll try this, but I'll modify the angle adapter with a line point.
This great idea !!!
<p>Awesome way of thinking, great instuctable :)</p>
<p>Nice idea you have there. INnovation is the key to new items. </p>
<p>Well said!</p>
This is awesome! Thinking outside the box. Beautiful.
<p>I never did like boxes :P</p>
Great idea! I'm a fan of your work.
<p>Thank you!!</p>
<p>Thank you Thank you, just what I need. You are a very clever Man. Cheers Pete</p>
<p>Thanks Pete, glad you can use it!</p>
<p>Very ingenious! I wonder how well the lazy Suzan bearings will hold up. It looks like you've selected a pretty robust lazy Suzan.</p>
<p>I also wonder how long it will last, but for now it's going strong :)</p><p>I've heard the right angle adapter could also fail from over-torquing.</p>
