scrolling plastic

Posted 08-29-2011 at 11:46 PM by kkvision

I have only been scrolling for a couple of months, and finding it very worthwhile for me. I am having a problem with cutting acrylic plastic. I have been using crown #3 & #5 blades. 2- 1/8 th inch 4"x4" glued together, my first try worked great but the next two, the cuts only melted the plastic and fused behind the blade. Any suggestions.

    Yes post in the main forum as most people do not even visit these blog postings. Also scroll slower with your feed rate and stack your acrylic in between some cardboard. That should help with the melting and fusing together.

    I've cut quite a bit of plastic. It sounds counter intuitive to put plastic over plastic but . . . . try taping over you plastic with packing tape. This has helped me tremendously. I also have some very fine files to help clean the edges as the plastic I cut seems to frizzle the edges. -------Randy

    Bizarrely enough, I've been scrolling for 17 years, and literally cut my first piece of 2mm acrylic just three days ago, and it did exactly as you describe (this was good optically clear stuff for a photo frame) - surprised the heck out of me to be honest! When I experimented it seemed to do it any any cut speed, and also when I used tape along the cut line. I had a peer through a magnifying glass while it was being cut, and the blade actually appears to liquify around the blade. Very odd, but the welded join behind the cut was much weaker than the surrounding acrylic, so was easy to snap to shape.
    My advice? Stick to wood!
    Have fun.
