I have an older Craftsman belt/disc combo sander, 9” disc/6” belt. Have never changed the disc, LOL, but it needs it now! The platen (or whatever you call it) is really grody, needs to be cleaned. What’s the best thing to use to get the old gunk off? Also, is there any chance of converting it to hook-and-loop? Might be a silly question….

Can you get 9” hook and loop? If so, that is a good way to go instead of all the adhesive. We have one in Arizona and I scrape the disk with a wood scraper and then wash it clean with lacquer thinner ( my favorite) and then apply a new disk. If you don’t get it cleaned well a new disk will and has gone flying off like a projectile!

When I used to use mine I had taken the disc off and either used a wire brush on it while it was turned on or I used sand paper when it was turned on.

Much faster when the sander is on.

About 8 months ago I glued 6 pine boards together to make a 15” x 2 1/2” thick board and then put a 8” face plate in the middle of it and turned it nice and round on the out side and flat on the inside.

I then put 3 coats of Shellac on it to seal it up and bought several grits of 15” disc paper from Grizzly. I mount it on my lathe when I need to use one. I think this way is so much better because it will not burn the wood because you can turn the lathe as fast as you want.

Jim has a pretty good method for a really old one. But I would hesitate on the velcro. Too fast. Now that I change mine out pretty regular, I use a HF heat gun to soften up the paper glue, and just peel it off. Wait a minute or two to let it cool and put on the new one.

Hello forest, there is a 12” disc system produced by Shopsmith, it is a Velcro product. I didn’t believe it would work, but, when I had one of the Shopsmiths I tried it and it held fine. I tried to find the info on it for you, but so far I haven’t located it. Maybe you are a better detective than I and can find out about it, you could adapt it for the 9inch I’m sure. Have fun, make some dust.

Hey Forest girl – -
I found using a heat gun really helped get the adhesive off (mostly with the disc) such that I could “blot” a lot of the glue off – - kind of like using a wad of bubblegum to dab up the remnants of teh errant popped bubble.

Then like others – lacquer thinner.

one thing I would beware of is that if you use much pressure on your disc – it generates a lot of heat, and the hook and loop will melt.

Can have the same happen when people try to do some “shaping” with a random orbit hand sander, then find the H&L doesn’t hold anymore. If you need the 9 inch disc to be really flat, like to touch up miters on picture frames, the H&L might round the corners a bit.

Thanks all for the helpful ideas! I did find the parts necessary to convert to H&L at 2sand.com . I didn’t find the hook part for the platen, and emailed them last night. There was an answer in my Inbox when I woke up this morning! I appreciate the cautionary notes, as I had not thought of overheating or rounding. I’m not prone to pushing hard with a sander or stock on a stationary sander, so I think I’m OK there. Will keep the “rounding” possibility in mind, but doubt I’d use it for miters and such. Will let you know how it goes after conversion (next month). Thanks again!
