These instructions are a complete step by step guide that will show you how to build a 9″ drill powered disc sander, and it should only cost you about $20 in materials.

This project is designed to by an EASY build. You can probably get most of it done in a couple of sessions. The most time consuming part will be waiting for epoxy and polyurethane to dry!

About the plans:

  • Formatted for normal sized (8.5″ x 11″) printer paper, so you can print them at home.
  • Includes Metric Version
  • Includes French Version (thanks to Jean-Jacques, a French patron!)
  • They include:
    • A complete shopping list for the materials you need.
    • A complete list of parts you need to cut with all the dimensions necessary (with images).
    • Step by step instructions that accompany and compliment the build video.

About the Disc Sander:

  • Dimensions: 17″ long x 10″ wide x 10″ tall.
  • Disc Diameter: 9″
  • Uses a corded drill to turn the disc (not included).
    • Do NOT use a cordless drill, as it may not be able to handle the load!

  • Table Saw
  • Miter Saw (Recommended, but not necessary if you have a table saw sled or another way to make good cross cuts)
  • 23 Gauge Pin Nailer (Recommended, but not strictly necessary)
  • Router (or some other way to make perfect circles).
  • Drill
  • Drill Press (Recommended, but you could get by with a regular drill)
    • 5/64″ or 1/16″ bit
    • 22mm or 7/8″ Spade or Forstner Bit
    • 1/4″
    • 5/8″ Bit
    • 5/16″ Bit
    • 5/16-18 Thread Tapping Bit
  • Sander/Sandpaper
  • Flat File

    Just finished this build and am delighted with the results. A great addition to a poor mans workshop. Love how Tommy goes about his business, he gives you the chance to follow along with what he is doing. He is also very responsive to any questions you may have. 5 stars.

    Mike – Thank you for the wonderful review! Check out Mike’s build in the customer gallery! – Tommy

    Holy smokes, these are the most detailed, thorough plans I’ve ever purchased from someone. Not only does Tommy give you step-by-step instructions, he explains WHY you’re doing what you’re doing as well.

    Can’t wait to get everything together and make this!

    Great plans!! Don’t use cheap bearings (Learned this the hard way)
    Tommy is extremely detailed is his plans and has very reasonable prices.

    Hi Tommy,

    This build is the real deal. I am a woodworking novice, and this thing was the perfect project to start a second life for an old, but merely used drill I’ve had lying around for quite some time. Your plans are super accurate, it’s a pleasure working along these. I’m looking forward to attacking the next project soon. And btw: with 120- paper applied, this sander kicks b****! Keep it up! Greetings from Munich, Germany

      Matthias, thank you for sharing about your experience! I’m so glad you enjoyed the project!

    This project was super. I just had difficulty finding a good epoxy.

    • Tommy Rich

      Thank you for taking the time to write a review! It sounds like you’ve finished the project now, but for the future, I recommend JB Weld Original, that takes 24 hours to fully cure. It has a long working time (several hours) and it cures VERY hard and durable. I hope this helps! Thanks again!

    Wow! I am hoping even a beginner like me can make this project. The plans and cut list and materials are the best details I have seen in any woodworking make up. I am stoked to get going on this project. I will probably have Tommy’s video going in slow motion while I try to put this together. Very professional grade. Thanks.

    Nice Video
    After watching the video I bought the drawings. I have only had one small problem but easy solved. It has been a fun build and good result (not as good as Yours).
    I can only recommend to try it out.

    • Tommy Rich

      Thanks for the review, Tom!

    Well documented and detailed plans. I found actual SAE dimension bearings instead of skate bearings (which all seem to be metric), which made for a much better fit for my 7/8″ hole and 5/16″ axle. Straightforward build and excellent results.

    Very well written and easy to follow.

  10. Stefan Geissbühler (verified owner)

    The plans are easy to follow with clear step-by-step instructions. The only (very small) hiccup was on page 30 with part J being marked as part I, but that’s small potatoes. The drill alignment and mounting (for my corded drill) took some figuring out, but once it was done I was ready to go. I love this tool! It is now one of my favorite tools in my shop and I find all sorts of great uses for it. I wonder if I could peel potatoes and carrots with it?? Thanks Tommy!

    • Tommy Rich

      Stefan, thank you for that awesome review! I have fixed the error so that future customers will not encounter it – thank you very much for pointing it out! I’m glad to hear it’s one of you favorite tools; it is one of my favorites as well. While I don’t recommend peeling vegetables with it, if you decide to do so, make sure you video record it 😉 Anyway, thanks again!
