ill give acetone a try, but mineral spirits, goof off and 3m adhesive remover didnt really make a difference. i was assuming that both sides would be like the bottom side (the latest pictures) like on a traditional 3 piece slate table where both faces are smooth. If thats the case and I am just scraping the grooves off, would it be best to do the acetone route, and use the origional top side, or just use the bottom side? I ask because i already scraped almost a quarter of the table and I do not want it to affect play. The bottom side seems to be in relatively good condition, aside from the glue on the edges. Ill return the super 77 and use fastbond 10.I have used acetone and zip strip before to clean a slate and both have worked. as far as flipping over slate, there are usually groves ground into the playing surface of the slate to help keep the cloth in place. if you have them you will now it and that is your top. You have to use that side.to get the best results. i myself would stop scraping if i where you. if you can't get it off with acetone and scotch brites then you are doing it wrong. It shouldn't take scraping to get it off unless you re being impatient.
As far as super 77 don't use it. I have 5 tables i have to go repair because i used super 77. Apparently they changed the formula and every table i have done with it since, the felt has come loose. I guess they sell the original formula under super 77 classic now but I'm not going to chance it. i will just go get fastbond 10 (scotch weld 10). A friend of mine who also does tables is having the same problems.
Thank you
