Cutting/Sanding Stacked Lips

I recently tried stacking 5 pieces of lexan .060 inch. I used "SCOTCH BRAND" Double sided tape to secure them. I did not have much success. There was too much variance. I first cut the bills close on a bandsaw and then proceeded to finish on a belt and drum sander. The bills shifted during sanding. My question is... SCOTCH makes 2 different double sided tapes. A temporary version and a permanent version. What brand are you using and which type? The SCOTCH temporary did not work well for me.

I use a double backed tape for working with plastic signs. I have had very good results with it. Please don't ask where I got it. I don't remember. I have had it almost 20 years and believe it or not it is still good. I am now on my last roll. I would suggest using the permanent type that is available as opposed to the temporary. I would think that it would hold better.

drop the tape get som 3M spray adhesive and use that! Spray both sides to be stuck together, let it get tacky stick together, put in vice for 5 minutes, stick your pattern on top cut out sand then soak in denatured alcohol for 5 minutes to loosen the bond and seperate them

have you tried this with leavinghe protective film on? I would think that as you pull the lips apart the film would pull off and you wouldn't need to soak them. This works for me with double stick cloth carpet tape.

I'd say, Yup, no need to soak as long as the protective coating is there. I've stacked 4 layers using spray adhesive, and had very little problem prying them apart after shaping.
I do need to clamp them together to let the adhesive cure for a bit though......did have some slip if I didn't do that.

soaking the lip usually leaves the protective film intact. When I use lexan i leave the film intact until I install the lip in the bait. This leaves the surface of the lexan virtually unblemished if I have to put any final sanding or tooling to the lip

I already have some on hand. Just never thought of using it. Thanks for the tip. Will give it a try. Thanks again.
