Turn Your TABLE SAW Into a DISC SANDER! (and Make It More Accurate...All For $40!)
Disc sanders are helpful for shaping wood and other materials...but it can be a nuisance buying one and finding shop room for it. This short video from The Honest Carpenter will show you a conversion blade that will not only turn your table saw into a disc sander...it will also help you calibrate your saw more easily and keep it accurate!
Just keep in mind that table saws spin consistently at about 4,000 rpms, whereas standard disc sanders can be adjusted for speed. So, table saws with sanding discs attached tend to remove material very quickly!
Thank you!

Love this style of video, quick, to the point, but useful
👍😁
One of the few advantages of being really old is that you can sometimes remember that an old idea has resurfaced. Craftsman (Sears) on the order of 50 years ago sold a purpose built sanding disc for table saws that used a sanding disc (glued on) both sides. One side was flat and the other side had a slight taper from inside to perimeter which, with some careful adjustment, allowed it to be used as a jointer. It actually served me quite well in this capacity in allowing me to glue up solid oak panels. That was a long time ago and I really can't say I've been an avid woodworker all those intervening years, so I can't say that there are no downsides to the system. I just know that I was impressed enough to purchase another one off eBay a couple years ago. I still use the flat side from time to time as anyone would use a disc sander.
What a cool tool accessory. I had no idea they existed.
SO glad I saw this!
I got one of these disks a few years ago as a Christmas gift. My experience with it is that I never did find a sweet spot for sanding without burning my pieces that I worked so hard to get ready for sanding 🤦🏻🤣 I was really glad that I was working outside that particular day - the smoke was rolling pretty good!
But it really is a sweet calibration tool. Buy it just for that, and give it a try for sanding … maybe you’ll have better results than I did!!
I never thought of that! This is really helpful. Thanks for sharing this review and technique.
That's a really cool hack, thanks for this!
Very good recommendation!
Merry Christmas to you & yours.
Valuable conversion advice, great job!
Very clever, thanks for sharing
I was thinking about same thing last week, good to know someone already has come out with one.
Cool idea. Thanks Ethan! 😊😊😊❤❤❤
I like it! For occasional use in a home workshop it’s perfect.
Thank you. Very useful video!
Kinda cool - thanks, Ethan! Merry Christmas to you and yours.😊
That is a great way to sand, never thought a table saw could make a less expensive and easier way to sand! Thanks Ethan for some more good information.🦾👍
Thanks for this tip!
I've seen a guy on RUclips use that sanding disc setup. He putting the paper on the other side of the blade. And then used the fence, and ran the board between the sanding disc and fence, which looked basically like he joined that edge of the board.. Which cleaned off the burn marks and such from the board. So with that said, what are you thoughts??! I was hoping you'd go into the up side, and down side of doing this, in the video. As the like tips you give on other videos, are generally useful. Anyhow thanks for another great video. Take it easy.
now that's something I could use
This video is very good. If you use the Kunlun tooth saw blade we developed, you can achieve higher results. The Kunlun tooth can make the upper and lower sides without chipping, bursting, or cracking.
Very useful. Thanks
This is awesomeness. This kind of post reminds me why i spend time on RUclips
This feature would definitely save me some time on Sanding. A lot of the items I have to smooth. I've been doing all my sanding by hand. 👷🏿♂️
🙋♂️THANKS ETHAN 🤗… for sharing an inexpensive suggestion to help us new ones👍💚💚💚
! Love the content!! Merry Christmas and Happy New Year!
Thank you, Timothy! Merry Christmas! 🙂
Cool. Thanks.
Great option that I didn’t know existed. Thank you for making the video. Cheers 👍😎🇦🇺
Great tip ethan for occasional use.
Merry Christmas to one of the top channels!
Thank you, Slaphappy! Merry Christmas! 🎄🎁
Great idea and video. I had an old disc sander my Uncle made. I throw it because it was dangerous! I feel it would be safer because you have the table saw top. I don't do wood working as my job, just a hobby for me. This would save space and money.
So the discs are adhesive backed. Can they be removed and put back on at a later time? Say I changed grit to 180 then went back later to a more aggressive grit. Per usual a video well worth watching.
🙋♂️THANKS ETHAN 🤗 A GREAT INEXPENSIVE SUGGESTION ❤ IT 💚💚💚
this is an awesome idea. particularly, where you have limited space and budget.
Thank you for your videos. Merry Christmas ti you & your family. Good luck & stay safe in 2024. 🌲🎅
This sanding disk is 10 inch and uses the full capability of the saw. Larger disk meand better table and fence alignment. And disks last longer since there is more area. Freud-Diablo 10" Calibration & Sanding Disk with 5/8" Arbor
These have been out for a long time, haven't used mine in decades it kind of a hassle to put on and take off unless you have enough work. The most useful function I found is dialing in flat miter fits, really shines for that with miter gauge, you can take minuscule amounts off.
Will this in any way damage/affect the motor of the table saw? Wondering if it would work with my new sawstop compact TS.
The same sanding disc works well on a compound miter saw
I wonder if the adhesive on the disc could begin to soften due to heat built up while sanding large areas. 🤔
can you put two different grits one to each side for more efficient sanding?
Before I purchased my Grizzly table saw, I watched a RUclips video that Grizzly put out on their table saw’s & accessories they offer. One was a sanding accessory like you are showing here. My Grizzly job site table saw can be dialed down with slower RPM’s. Been thinking about purchasing this. Your video is good timing for me. Thx!
Being able to dial down blade speed makes this about perfect, Stephen!
Ethan, nice run- through. One of my favorite features on a Shopsmith multipurpose machine is the 12” disc and variable speed, which allow me to run the disc as low as 700rpm, if the job calls for it. 4000 is crazy-fast, so if someone is going to use this they need to be prepared to move the stock quickly, and don’t forget to use a crepe rubber abrasive cleaning stick to keep the abrasive free of build-up. Failing to do this will surely set off the shocks smoke alarm. Scott
You could get a potentiometer that plugs into the 120 plug to slow it down
Ahhh yeaaah... the Shopsmith. Respect.
3:07 it adds to a message when presenter has a black eye ;)
thanks for the video.
wow. never heard of such a thing. and, if i hadn't heard it from you, i'd be dubious of its safety. thanks
Much safer than a saw blade, regardless.
I've got a pin dial but don't have the mitre guide attachment, any chance you have a link to that or a name for the dial holder I can search? Thanks
Does the disc remain accurate for calibration after a bunch of sanding use?
nice
Thanks for sharing this, I had not seen these before. I still don't think it's very practical. You can't get very close to the sander to use it (the table is in the way) and the setup/teardown before being able to use it or to use your tablesaw again makes it a lot less desireable.
You should look at Mike Farrington's product with the tapered disk. It turns the table saw into a sort of Saw-Planer-Jointer-Finish sander.
Im a newbee to this craft but that looks kinda? good if you're in a pinch and looks like You gotta ne super careful with the pressure otherwise the table saw could be ruined. I would only use this as last resort but that just only my thoughts
l live in the UK across the pond l have a Dewalt DW7485 table saw it take a 8 1/4 saw blade 30mm bore can l get a calibration & sanding disc
I purchased the exact same CMT disc last year. and use it on a Radial Arm Saw and a DeWalt compound sliding miter saw....
I work with steel and aluminum.......a great piece of gear for the metal shop .....oh yeah....the wood shop too.....
is there a risk of damaging the saw by applying torque in a way it wasn't really designed for?
As others have mentioned, you have to be careful how much you side-load the spindle. Unlike disk sanders, table saws are not designed for side load on the spindle.
Thanks. 🥶🖤🔔👍🏻💓
I have an old small Craftsman table saw that I was going to throw away. Perhaps I should try this instead.
You're Amazon link is to the 8" version.
Question #3 - will using it as a sanding disk ruin this as a calibration tool (e.g., pressure on the disk from sanding make it no longer completely flat)?
That was the first question that came to my mind,
If you are deforming a solid steel plate, you are using way too &%$ force!
Ithought about doing the same thing using a worn-out diamond wetsaw blade
This sanding disk is 10inch which better uses the capability of the saw. Plus a large disk would allow better table and fence alignments. Freud-Diablo 10" Calibration & Sanding Disk with 5/8" Arbor. A larger sanding disk will last longer since it has more area to use.
I have this saw too. Any tips to make it quieter
Leave it off.
When ever i buy table saw i will try it 😅
Using a wornout stone disk with the same arbour can also be used. Unless you don't have one.
Is there a reason why you cant put different grits on either side?
No, you can face it any way you like, Andrew! I was just leaving the fence on
Didn't @MikeFarrington already invent one of these? I wonder if that design got sold to CMT?
He didn't "invent" it; the idea has been around for decades. And his plate is different in that it has a slight taper and is designed to have stock ran past it, between the disc and the fence. Because the disc isn't perfectly flat, it allows the sanding to take place more at a "contact point" so you don't get the kick-up as the work piece is pushed past the arbor
Wow. Won't this be handy! I have a spindle sander for concave (inside) curves, but it's a lot less sure for convex curves. You could even stick two different grits on each side of the disk for coarse and not so coarse sanding. Thanks.

When all's said and done, there's a lot more said than done.
Uhoh. It's the finger waggle of truth!
👍👍👍
kind of a dumb question here - but if there is only 1 metal disc and its not hook and loop, how do you change out the pads (without ruining them?)
Actually, you can't - you just use up one disk.These are pretty much for rough sanding to shape, with using a hand sander to finish off the work. I kept mine at a 120 grit and with the fast speed of the table saw, does the job nicely. Get a abrasive cleaning block to prolong the life of the sandpaper.
Adhesive-backed pads are used in other sanding applications, this is probably the same.
Maybe I'm blind, but I don't see the product links.
I created "the worlds most dangerous sander" by sticking sanding discs to an old blade...full speed. It was fairly unforgiving- you really needed to sneak up on it with 100% focus. This product is clearly a better idea
All other things aside what is the meaning of RPMS?
Revolutions per minute, Harry. Essentially a measurement of how fast the disc is spinning.
Oh, you mean RPM. Happy Christmas and a very Prosperous New Year to you and your family.@@TheHonestCarpenter
Umm. No. Especially with Harbour Freight just down the street.
If pushed too hard the thrust bearings will fail...but for a small, DIY shop, perfect solution.
It sands so fast I think my board might disappear if I push too hard 😂
Why would you push that hard when power sanding? Any board that has internal stress will push harder on the blade than anything done sanding.
Just a little math on the speed of that disc at 4,000 rpm...the periphery is traveling
at 88 feet per second, or 10,466 feet per minute, or 1.982 miles per minute or
119 miles per hour......so....if you were using a 10 inch blade and it decided to
grab a piece at send it your way.......watch out.....
88 feet per second is 60 miles per hour NOT 119
You should stay away from power tools.
I don't think i would want to put my saw through that type of force on the side and take the chance of braking my new table saw
Cutting nearly any chunk of wood will put more side load on a blade than any sanding effort should ever apply.
Mike Farrington (a fellow YT'er) has much better versions of this for sale. He's been using it for years.

I don’t see any kind of issue with this adaptation for the table saw, as you said “apply gentle pressure”. There are more situations that the arbor and bearings would be more stress cutting wood due to the shearing forces that are freed from wood grain even if you have your riving knife.
First
Sorry I think I was number 1! Great name to you
Hmm… i think the ball-bearings of the saw are not really built for this kind/direction of force🫣…and the Edge isn‘t totally perpendicular as well, because the disk/motor mount bends when you apply force …
@@Grauenwolf yea, that‘s true. Never work with too much force applied…
Being myself a joiner, i was thaugt that perpendicular force to the blade is not allowed because of tooth tearout (yea, i know this isn’t the case here) and the stability (within the blade) is not given/tested/guaranteed. And if so there are special blades for panelsaws with extra thickness (up to 15mm) to groove (i don‘t know how to name it…the blades are called “Kehlblatt“ and you get a upsidedown U). If you use blades like these you get advised to shove the panels diagonally over the blade to reduce stress within the blade and mounts.
But yes, you should never apply force… this is when the most accidents happen, better let the blade/sand paper to it‘s work. We have to keep in mind that tere are always unexperienced ones without the knowledge, who will apply way too much force.
My biggest concern is the free spinning sanding disk because of the missing housing and the risk that someone will ruin the precision (if it really given in such small tablesaws🙈😄).
Greetings from Germany
Too often on RUclips, people think any spinning tool can be hacked into another spinning tool. Damaging the tool is a minor issue. Freak accidents is more tragic
Portable tablesaws tend to have much too high rpm as well. If that sandpaper flies off it can cause severe injury.
It's much safer if used on a belt driven tablesaw motor.
I've been in the industry for decades, both in custom shops and general contracting and I've witnessed horrific injuries due to safety not being priority.
I wonder how the shopsMith was made to be used the same way?
@@ChristIsLord229 shopsmith has a speed changer (belt driven) that can change the rpm as low as 500rpm and as high as 3,600rpm.
This might work slightly but is largely useless. The speed of the saw is way too fast for decent sanding without burning. You need to be very clever to get any decent finish. Also, do not use it very often as lightweight saw spindles like this are not built for side pressure on the bearings. A good way to shorten the sawshaft life.
As someone this is concerned about safely using products the risks to this modification seem too high to me to consider. It just seems like it would be way too easy for someone to get hurt if they are not highly experienced and paying real close attention to what they are doing. I would hate to see that happen.
Imo not a good idea. Table saw spinning much faster then needed for sanding.
I keep my cord disconnected and in sight as well, however your next 3 cut shots do not have it in sight. I keep it in sight until the plate is secured back in place.
I have no words for this....other than stupid. tools are designed for a specific use and purpose...this IS NOT it's use. seriously...a table saw as a disc sander??? what's next, a grinder as a chainsaw? all it takes is for someone to put too much pressure and something goes wrong. will you feel any guilt in knowing you injured someone because of your video? unreal...just...unreal. if you need a disc sander...BUY ONE they are cheap enough...that's what they are designed for and only for...not to be used as a lathe.
Sorry not going to happen for me! You are going to stick a piece of sandpaper on a disk that is rotating at 4,000 rpms. You better be NO WHERE near the sandpaper disc if it tears/fails and starts flying off. Or wads up and gets stuck between the disc and the tabletop. Little hard to believe you would support this.
Question #2 - will the sanding disks come off cleanly (and relatively easily)?
Question #1 - will this work with a Sawstop?
Why wouldn't it?
