Not safe unless you can cut the teeth off of it so it is round. You can buy a flat disc specifically designed for that purpose here.

Note that the table saw is probably going to run much faster than dedicated disc sanders typically do so it will be more likely to burn.

Ya, that motor is going to way too high in the RPM range for what you’ll want. May want to look at a speed control option for it to slow ut down.

I haven’t seen one in a while, but they do sell a flat disk for a table saw that you can attach sandpaper to. Using and old blade seems to me to be just asking for a trip to the ER.

I’d resist the saw blade option. If you do decide to make a disc sander you are going to need to use a variable speed controller or pulley combo to slow that baby down. Literally hundreds of DIY disc sanders on youtube. In fact, so many that I can’t even find the one I made to link to.

Found it. But there are much easier ones to make.

With very little materials, a 1725 RPM motor, and a little time on your part you could make a disc sander. I found a motor this last summer and mounted a flange to the shaft then added a disc to it. The table I made on it doesn’t tilt but I have other tools that will take care of that. It is cheap, easy and even has dust collection. My cost for the 3/4 HP motor was $10. The rest was stuff I had. Several DIY videos on YouTube.

I have one of those discs^ that I’ll send you if you want it. Just PM me your address. I got it a long time ago and used for aligning my arbor with the miter slot. Never actually put sandpaper on it. But, it’s only been used once and is just taking up space. It’s yours for the price of shipping. As others suggested, you might want to see about slowing the motor down though. If it’s a belt drive, just a pulley change might be all that’s needed.

Thanks to all who commented here and you have confirmed my suspicions that it is not a good idea so I will find another way. I’d rather be safe than sorry. And many thanks HokieKen for the offer of the disc ( didn’t know about them before so learned something) but I shan’t be needing it now as I will try something else. I live in Thailand and the shipping plus the huge tax I would have to pay made it a bit of a non starter for me anyway but thanks all the same.

Not a good idea, way too many RPMs for sanding.

I understand the RPM’s are too high,
so how do they get away with making a disc specifically for your table saw?

I know the pros and cons, but I guess it works for some things. Takes a light touch.

Kinda like belt sanders.

In the hands of someone with experience, it’ll work great and cut down the time it takes to do an operation.

In the hands of a novice, it’ll have you building new parts or modifying your project before you know it.
