How do you remove the adhesive from T sanding bars? I've tried acetone but it's hard going. A single edge razor blade works but it's also hard going.
Any ideas?
Thanks,

Soak it in paint thinner, then scrape with putty knife. Razor blade is not good: it makes burrs and uneven surface for re-use.
To remove the left over glue, can use laquer thinner.

I presume you're buying the pre-cut, self sticking backed sandpaper as they can be a chore to remove.

If this is the case, save yourself some money and aggravation and buy the sandpaper at your local hardware store and cut to fit the T-bar. Lightly (operative word here) spray some 3M-77 spray on the back side, let dry for a couple of minutes, then apply to the T-bar.

When it's time to remove the sandpaper, it should peel off leaving only a slight glue residue that can be easily taken off with acetone and a scrub pad. Should any paper backing remain on the T-bar, acetone and a putty knife will be your friends.

I have tried acetone, lacquer thinner, paint thinner and rubber cement thinner and nothing works.

I use a heat gun to heat the sandpaper and it comes right off with very little adhesive left on the sanding bar. Alcohol works to remove the left over.

Try Goo-Gone It works

Roger the Goo-Gone! Works great for removing adhesives including that from masking tape. Regards.

I started using a water soluble glue for my T bars. Just use water on the sandpaper to loosen, finish cleanup with good old dish soap. The glue does take some time to dry though.

I use carpet tape from hardware store and it is pretty easy to peel off.

Good tips guys. I'll give em a try. I was using the self sticking backed sandpaper. I think they made that stuff so you would have to buy new T bars.
Thanks for the advice.

Clamp the bar in a vise and use a heat gun and spatula. It will take it right off. Then use lacquer thinner to remove the adhesive. Acetone evaporates too fast but can be used as a final wipe.

I agree with Ed Stefan as far as sandpaper goes. Adhesive backed sandpaper is never good quality. Buy good sandpaper, cut it slightly over size, apply a light coat of spray glue on both the paper and the block and butt the pieces together to cover the entire block. Use an old blade to trim it.

My Feedback: (11)

I have to disagree here. I bought some of this sand paper (yellow in color), 150 grit and man, that stuff never wears out or seems to get clogged. I thought I was paying a lot for a small roll of the stuff ($6), but I just built and sanded a 1/6th T28 and only changed the sandpaper on my T-bar once. Of course I bought some 400 grit at the store to do the final sand.

I don't know what brand name you bought, but I find the "SandBlaster" (I think by 3M) is more expensive but definitely worth the extra money. This stuff lasts a lot longer than any other sandpaper I've purchased.

I don't know if this comes as self-adhesive backed, or not, but the regular backing is very good.

Ed: I fully agree with your comments on Sandblaster. Thas't what I am using now--get mine at Ace Hardware. Regards.

Thanks again. I'll try that Sandblaster paper when I return to the states (and decent flying fields).
