Colin, yours has become one of my favorite channels. While I enjoy quality tools, I appreciate that not every tool in your videos is from one of the high end companies like Woodpecker. I have Starrett in my collection but I also have General, Harbor Freight and everything in between. This sander build is a great video.
Love your videos Colin. Great build! Just a quick tip, when gluing onto your disc, just spray the disc then apply the full sheet, then trim the excess. This way you won’t have issues with aligning the sandpaper to the disc after it’s cut. Less messy and easier when working to align surfaces! Can’t wait for next video.
I had the same thought. I typically use 3M 77 spray adhesive which is marketed as permanent on my sanding sticks and disc sander. To change sandpaper I warm it up with a heat gun and remove any excess adhesive residue with mineral spirits (takes a few minutes but much better than alcohol/lacquer thinner/acetone).
Almost identical to the one I made about 25 years ago except your sander is fancier with the pivoting table. I didn't have a hub so I just used an aluminum pulley wheel about 3" in diameter and screwed it to the plywood plate. I still use my disc sander but after seeing your version I think it is time to make a couple of improvements to mine.
Colin you are my new go to person for information, you seem to know what you are talking about ,I have been watching you for sometime and i am always falling back to your web site you are the man you explain everything so well and clear
Cool idea, Colin. I have an old furnace fan given to me for free, but I don't know how to power it, and did not have a need. Now I want to convert it into a disk sander. Great idea!
@@IsaKocoglu Got them off the inlaws. They live on property with tank water, and mentioned that they had to replace the pumps again. (The seals or pressure switches fail) They had 4 and we got one to work again by mixing and matching parts, so 3 came home with me. \o/
*MikMech* After commenting above, I looked for some off Gumtree. Too expensive where I am from (south east Melbourne). I hope you put them to good use MikMech 😉👍🏼
The motor you are using is from a Ridgid drain cleaner. you might want to give the outside a good wipe with a rag with bleach on it. They often get human waste on them.
Colin, I am forever appreciative of your videos! I followed your instructions on making a disk sander and all came out very well! Your channel is fantastic and one of my favorites! Many thanks and keep the videos coming!
This just popped up on my feed, this is my next project. Going to see father in law to fix his shed who also happens to have a washing machine motor. Say no more, great video
very cool sander! i now know what to do with that old motor out in the garage... this will be a great build on some cold winter day... thanks for paying this forward! cheers from providence ri
Just have read the article, also liked it as much as watching your videos sir. Thank you very much for being that positive and understandable, i can lift up my english too ))
Very interesting video. Thanks for sharing. Some weeks ago I made a quick setup with a hand held power drill horizontally mounted and completed with a hoop and loop disc to which I could add sandpaper. I did a short test run but was not completely satisfied. From your video I learned two things: my drill has enough power (about 550 W, which is more than 1/3 HP). My sanding disc is only 5 (or 6) inches in diameter, so that's OK. I found out that I made the construction to low: in my case the wood touches the sanding disc under the center point line and that should be above. So that is two problems solves. Remain two other things which I can change but I could not find information on that in the video, nor in the article. What RPM is necessary for making it work all right? (or, what RPM is the motor you use in the video?) And what grit sandpaper is necessary to use?
a simple way to make a disc sander, although a bit more expensive is to buy a shopsmith disc sander disc, it will mount to a motor with a 5/8 shaft or one with an adaptor sleeve
Horsepower ratings on motors turned into something of a con job after a point making these appliance motors seem underpowered to read it's rating but surprising upon using them. Don't forget to keep those "peak" HP motors topped off with authentic snakeoil... Another awesome job, Colin, I have some motors like this I need to put back into a useful state.
😷🤔🤔🤔😷 tried this today with similar 1/3 hp motor. Results were not too good. I used your table saw method for cutting my circle and used that center hole to mount the circle to the motor. It shook so violently that I was afraid the workbench was going to fly away. Any advice on balancing it safely.
Good video Colin. I'd like to make one of these. Where did you find the flange to go over your motor shaft? Is there a site online that you purchased from?
There's more to it than just scaling up. You have to take into account the linear speed of the surface. The larger the diameter, the faster the disc is moving over the workpiece *AT THE SAME RPM*. For example, the edge of a 6" dia disc at 1760 RPM = 46 feet/second. I you have the same RPM at 9", it's 69 feet/sec. Looking at my 9" sandpaper, the max RPM is 2200, which is 86 feet/sec. That means if we scaled up to 12", that's equivalent to about 1600 rpm. At 24" that's around 800 rpm.
Good build Collin. Several have asked in the comments, but I don't see an answer. What is a good motor RPM for an 8 to 10 inch sander? I've saved several old motors, from various sources with various specifications.
i just built a sander, but used a pulley instead of this hub. Darn it. I was wondering, how did you center the hub on the disc. Also I'm going to use MDF for the disc. I have wobble in the one I built. Any suggestions on truing the disc? Chazz
I was wondering if you know how many rpm's your new disk sander is running at? Why I ask is it sounded a little fast. Do you think you could put a speed switch in the power cord? That should keep the amps and still drop the revs. Great idea 👍👍 thank you
Thanks Colin! I was wondering how to quick put together a sander. I have 2 motors I could use, bought off of Craigslist. One's only ¼hp, the other is ½hp, but 3450 rpm. Do you think that would be too fast? It's double shaft, so I might mount a belt sander on one end.
Great video, Colin. I have started building one of these but am concerned that it will be hard to remove the sanding disk from the wood backing plate when it's time to change sanding media. I was thinking of covering the disk with plastic laminate (Formica-like material). It that a good idea or would that just be adding a more potential problems?
leider verstehe ich kein Wort,spreche nur deutsch! Wie heissen diese >> Chicago Die Casting 2123 Die Cast Hub, auf Deutsch? Habe auch noch so einen Motor,nur fehlt mir die passende Scheibe,für die Holzplatte. Gruß Jürgen
Will you adopt me? Im 32 years young potty trained and somewhat house broke haha. I just Love. Love your Videos!! and you have the Nicest personality! I truly wish i was your Neighbor or Close Friend. Take Care and THANK YOU so much! For all your Wonderful Videos. 👍👍👍
Good video great idea. I have a 1750 Rpm motor I am going to build something very similar. Couple of questions, what RPM is the motor? Are you concerned about sanding dust getting into the motor with extended use? I noticed that the center of the sanding disk is below the top of your table I guess that is intentional because the center of the disk is turning much slower than the edges so it would provide very little sanding
You can just blow the motor out with compressed air every week or two. Its mainly just keeping the switch plate inside clear. Dry dust wont cause an earthing issues but damp sawdust can
I have 1750 rpm 1/2 hp motor. Started making mine today . I also have one that is 3400 rpm but I thought that would be to fast for sanding . We will how it turns out
What rpm is the motor you’re using? Also, is there any concerns with how high up on the disc the work rest sits? I notice yours is a little above centre, would it matter if it was below centre to give more sanding area? Thanks for the video, Colin. I think many of us have a motor or two sitting around in the garage or basement and this is a great use for one. PS. That double shaft motor looks like it would be perfect for a buffer or grinder.
I’ve thought about that as I have a few of them laying around. I’ve not done it because I think vacuum motors have a high speed with so little torque they wouldn’t be appropriate unless you wanted it to remove very little material. If you try it, let me know how it goes. Also, note that vacuum motors depend on the air movement to cool themselves so be sure whatever you design includes it’s own motor cooling. Good luck!
Can you please clarify the name of the hardware that mounts on the shaft? Hob, hop, hub? If I can clarify I can search -or if you have a link to an example? Thanks for great video.
Thanks guys, using all your suggestions has me on at least a somewhat successful search path - has led me to "motor shaft flange connector" - but I'm still searching for large ones, lots of tiny ones showing up. Appreciate the help. :)
It's a motor from a roto router plumbing snake they have fwd and reverse on them and they always have a foot switch like that so you can operate it by yourself if needed
Thanks Colin, watching this reminded me that I have a couple of extra motors in my yard barn, but no disc sander other than a plate that will go on my table saw like a blade. I just have to put a piece of sand paper on it. But this has inspired me to make one of these and have a disc sander that is ready to be used without having to remove my table saw blade. Thanks for being willing to show others how some things can be built in one's shop.
Spray adhesive is mostly just very tacky and will keep the sandpaper in place but also allow you to peel it off and replace it later when it wears out or gets torn. PVA will bond more strongly since it will soak into the paper and the wood and make the paper really difficult to remove.
@@halsonger1317 I'm thinking that perhaps a coat of shellac or finish on the wood disc would keep the PVA from sticking so firmly onto/into the wood disc.. Also a heat gun makes removing PVA disc much easier.
You have to watch this video closely to see all of them, but there's a real whack of nice little tips in here. A good video, and a nice sander as well. I'm going to keep an eye out for used motors now...

Did the same thing with my old pool pump motor. Been using it for about 12 yrs. My pump hp rating was 3/4 hp. This pump was a 110v pump. Great vid
Thanks for watching!

Thanks for watching!
Great idea. I don't need anything big. So think the 6" hook & loop will work great.
The beauty of this is that you can make multiple sized disks with any grit paper that you may need
Glad to see someone doing jobs like this, I`m close to 80 & have done things similar bur don`t know how you guys put it here for information THANKS

I have always wanted to make one. I have an old variable treadmill motor. Now I have a video I can trust on how to do this.
Hope it helps! Thanks for watching!
I'm going yard sailing TODAY!!! Thanks for the video and idea, that looks AWESOME!
A single wrap of aluminum ducting tape makes a great shim for the shaft fitting.
How did you balance the wheel? It looked perfectly balanced the first time you started it up.
The motor you are using is from a Ridgid drain cleaner. you might want to give the outside a good wipe with a rag with bleach on it. They often get human waste on them.
Well I know what I am going to build with the old motor I have. Thanks Colin.

@@johnjohnstone254 Yes, but how do you get it perfectly ballanced when attaching it?
There’s a set screw on the hub.

Which one is better to get, a bench top disc sander or an oscillating sander?
Wondering if he should have included a step to ensure the part rest was square to the sanding disk. Thoughts?
Are you going to make a grinder/ polisher with the other motor ?
👍 good job,sir how do we remove the paper

Just wondering what glue you’re using. When it comes to changing the sandpaper dose it come away easily?
I think this question deserves an answer...

There's more to it than just scaling up. You have to take into account the linear speed of the surface. The larger the diameter, the faster the disc is moving over the workpiece *AT THE SAME RPM*.

Jason Brooks Sander Disc Plate
The correct term is hub. It sounded like he said hob; his accent. A hob is a tool bit used to make gears, and a hop is a grain used to make beer.
@akbychoice, I was replying to Jason sorry if this came out as rude to you; that was not my intention
Frank Herring nope not at all. I just posted what I could find and one was through sears parts direct
Thanks guys, using all your suggestions has me on at least a somewhat successful search path - has led me to "motor shaft flange connector" - but I'm still searching for large ones, lots of tiny ones showing up.
Appreciate the help. :)
Why would a furnace fan motor have a foot switch? I really doubt that was a furnace fan motor.
J Will I was thinking it might be from an industrial sewing machine.
It's a motor from a roto router plumbing snake they have fwd and reverse on them and they always have a foot switch like that so you can operate it by yourself if needed
where did you order the flange from
What rpm is your motor? I have a 3/4hp 1750rpm motor I've been wanting to make into a disc sander but not sure if the rpm is fast enough.
Juan Jacobo after some googleing I found that most 12 inch disc Sanders are 1720 to 1740 rpms.... Seems you have a motor that will work....
That should work fine. Thanks for watching!

Interesting little build, thanks Colin. That aerosol type adhesive is rather expensive - is there any reason that you couldn't just try PVA?
Spray adhesive is mostly just very tacky and will keep the sandpaper in place but also allow you to peel it off and replace it later when it wears out or gets torn. PVA will bond more strongly since it will soak into the paper and the wood and make the paper really difficult to remove.
@@halsonger1317 I'm thinking that perhaps a coat of shellac or finish on the wood disc would keep the PVA from sticking so firmly onto/into the wood disc.. Also a heat gun makes removing PVA disc much easier.
As noted, I used the spray adhesive because of the easy removal, PVA will probably be too strong of a bond. Try a look tack glue.
