ike Posted February 22, 2014 Report Share Posted February 22, 2014 I have never cut Plexiglas and was wondering what blade to use and speed. This is 1/8 thick Plexiglas with paper on both sides? Quote Link to comment Share on other sites More sharing options...
Ron Johnson Posted February 22, 2014 Report Share Posted February 22, 2014 Good morning William What blade and speed to use all depends on the project your cutting. Normally I use a # 5 Olsen or smaller depending on the project. A medium speed should work fine. Quote Link to comment Share on other sites More sharing options...
oldhudson Posted February 22, 2014 Report Share Posted February 22, 2014 I've cut plexiglass with a table saw and Fein multitool but never a scroll saw. I anxious to hear what others have experienced with this. Quote Link to comment Share on other sites More sharing options...
bandaideman Posted February 23, 2014 Report Share Posted February 23, 2014 When I have cut plexiglass which has been a little while. I found where it was recommended to use duck tape on the top and bottom over the paper and put the pattern on that then cut. It did seem to go well. With the duck tape I could speed up a lot. I had cut very slow speed or it would melt back together. Not sure if this makes since but that is what I do. Quote Link to comment Share on other sites More sharing options...
LarryEA Posted February 23, 2014 Report Share Posted February 23, 2014 A #3 and cut at a fast speed. Leave the paper on and add the pattern. Not necessarly in that order. Larry Quote Link to comment Share on other sites More sharing options...
spirithorse Posted February 23, 2014 Report Share Posted February 23, 2014 Hi, Ike, This is the best info I could find on cutting plexiglass. http://www.thewoodbox.com/data/scrollsaw/scplexglassinfo.htm Good luck and God Bless!Let us see your project when you are finished and let us now what worked best and what did not work for you.

amazingkevin Posted February 23, 2014 Report Share Posted February 23, 2014 (edited) Wide toothed blades helped me a lot with 3/8" lexan The space between the teeth helps remove the cut plastic better instead of melting fine back together.

Multifasited Posted February 25, 2014 Report Share Posted February 25, 2014 (edited) I like candle wax ,and shelf paper.coursest blade the thickness warrants.with steady advancing feed ,staying in one spot bad idea!

Overfifty Posted March 2, 2014 Report Share Posted March 2, 2014 Good morning William. I, too, use a DW788 (a recent acquisition). I purchased a piece of 3/32 " Plexiglas and after experimenting with a number of different blades, and speeds I reverted to my Dremel. I found that the shavings from the Plexiglas clung together and wouldn't dissipate like wood shavings despite having a superb aftermarket blower. I was constantly having to stop and clear the shavings from around the blade. Cheers, Barry. Quote Link to comment Share on other sites More sharing options...
amazingkevin Posted March 2, 2014 Report Share Posted March 2, 2014 A band saw makes very fast cutting as it cleans out all it cuts fast so nothing melts back in together Quote Link to comment Share on other sites More sharing options...
Dan Posted March 2, 2014 Report Share Posted March 2, 2014 Whatever blade you choose, practice first. If the blade speed is too fast the Plexiglass may melt together during the cut. I found that covering the top and bottom with packing tape helps cool the blade tremendously. You can leave the paper on the Plexiglass and after cutting remove the pattern, tape and paper very easily. Quote Link to comment Share on other sites More sharing options...
heppnerguy Posted March 3, 2014 Report Share Posted March 3, 2014 I tried cutting some plexiglass and that was when I too became a welder instead. I should borrow someones welder and try welding two pieces of plexiglass together with it and maybe I will find that I can cut the plexiglass that way.. just kidding, I have some plexiglass hanging around, only because i remember making little hearts in woodshop in grade school,out of them but do not remember how we cut them. so I am interested in seeing the outcome here Dick heppnerguy Quote Link to comment Share on other sites More sharing options...
ubgoofy2003 Posted March 7, 2014 Report Share Posted March 7, 2014 I have never cut Plexiglas and was wondering what blade to use and speed. This is 1/8 thick Plexiglas with paper on both sides? With plex that has paper on both sides, I use the blade that I like best. I can cut fairly fast (normal) & have not had the plex fuse together behind the blade. I even cut two 1/4 inch pieces stacked, but, a little slower, naturally. I have had good luck with all of my cuttings of Acrylic, but, it has to have paper or tape on both sides to do as I do. I even use spiral blades on it also, no problems. Good Luck amazingkevin 1 Quote Link to comment Share on other sites More sharing options...
