Hi there, I have few eps foam block left ( since my friends gave up the boardbuilding diy project), these blocks are 1’ x 6’ x 8", its intended to glue between a plywood stringer. Now I just want to glue it up with epoxy resin and turn two blocks into a 2’ x 6’ x 8" which capable to make some mini shortboards or skimboard. I dont have any experience in hotwire cutting a epoxy glued block. Does it hard to cut? Thanks Crabie

(strongest strings are violin strings) Good luck. Peter Rijk.

(strongest strings are > violin strings) Peter, I’ve been meaning to ask you this a long time. What kind of setup do you use for hotwire cutting? Powersource, etc. Do you use the thickest or the thinnest string? Does it matter? Best regards, Håvard
I think I did not give a detail description…Actually, I just want to use the eps block to build stringerless mini short board cos my electric planer ran out of order. Can do it w/o a power planer. Therefore, I want to glue two pieces eps. Harvard, I m using a transformer, I dont have in hand, may be to reply you tomorrow, > Peter, I’ve been meaning to ask you this a long time.

Use a thick string the smaller ones break when heated and you don’t want that to happen halfway. I tryed to draw the simple frame I use for cutting, its in the board section look at diagram. Thats about it I think. Peter Rijk.
I m using the ac transformer, it’s a 3 amp with few choice output from 9v, 12v, 15v, and 18v. I diy two hot wire bowl, one is 18 inches and the other is 28 inches. While I using the 18" bowl, the 9v output doesnt provide enough heat, then I turn to 12v, its pretty smoothy but still too slow. By increasing to 18v, the string getting overheated and turned into orange color, then the string is easily broken. My experience is 12v is the maxmium for a 18 inches bowl. Now I use the 28 inches bowl to cut a 24" width eps block, 9v output is under power, 12v is slowly cut, 18v in someways is overheated. I did make a power switch to adjust the heat but not success. In addition, I buy the string in hardware store, there’re three different size. The thickness one is something like a flat razor, I bought a few yards but did not try. The medium one I m using is quite ok but hard to tell you the size, cos the guy who sold me the string did not know it too. The finest one it did not work at all, I dont know why. I saw a handy bowl ( just a few inches height ) operates with 2 pcs of 3A battery, the string is really really thin, its much thinner than the one I m using. If you try a thicker string, theoritically u can use a higher output. Try to adjust the power output or you 'll melt the foam.
