Cleaning the sanding disc?

[ehbowen]

When I acquired my new-to-me 1980 Shopsmith the 12" sanding disc had a piece of adhesive-backed sandpaper which had apparently been there since...1980. The sandpaper came off easily enough, but there's a lot of lumpy and hard-to-remove adhesive still stuck to the steel sanding disc. What's the best way to clean it off? Acetone? Alcohol? Scraping? Or bite the bullet and buy a new disc?

Solvent such as acetone does help -- but particularly if everything gets good and warm out in the sun.

I'm often reminded how many chemical actions really do better with heat... just like they taught in school, but easy to forget!

Lacquer thinner works also but it is extremely flammable. As Chris said warming it is also recommended. You get good hot sun in Houston. My sister in law lives there.

You probably need solvent to get all the gunk off but you could mount the disk and use a scouring pad or something like that while it runs to get the heaviest material off.

Leave the disc out in the afternoon sun for a couple hours and then (with it still hot) clean the surface with acetone. Be liberal with the acetone. Be prepared to "scrap" some of the deposit off with a plastic putty knife.

Y'all missed the most significant point. He can reuse his!


WHOOPS! That was a different recent thread. (freezer then pull disk off and adhesive stays with the adhesive disc leaving the metal disc clean)
