Typiska förslag tycks vara att använda bänksågar med fintandade blad för (raka) skär i polykarbonat. Om det inte var för begränsningen av bänkverktyg skulle det förmodligen vara vägen att gå. Till exempel:
Polycarbonate sheeting can be cut with a basic pair of hand shears if the thickness of the sheet is less than 0.125 inches (1/8 of an inch). Thicker sheet material will have to be cut by means of a mechanical saw. Straight cuts can be performed by using a circular saw. Curved cuts are made using either a vertical band saw or a hand-held jigsaw. In all cases for mechanical cutting of the plastic sheet, a fine-toothed blade must be used or else severe break out will occur to the plastic's cut edges. (Source.)
I need to cut a sheet of Lexan. [Neither] scoring it [nor] using a jigsaw [seems] to yield a good result and a clean edge (even after sanding). ...
[It cuts] well with a band saw or table saw using a high speed with small teeth. A jigsaw might tend to crack acrylic, but will be fine for polycarbonate.
"We just used a table saw with an aluminum cutting blade on it. One had to use extreme care when cutting. Go REALLY slow..." (Source.)
Men vissa bärbara verktyg är föreslagna av olika personer:
I use a regular knife, just score the plexiglass, use a straightedge when you score it. Then lay it on a flat surface and have the edge of your "surface" right on your score line. Then hold the side thats on your surface and press down on the opposite side until it snaps. (Source.)
(Det verkar även vara specialiserat " scoring knives "för denna typ av användning.)
One of the best ways possible seems counterintuitive, but is very accurate and easy to clean , and much less likely to chip, but get ready to sweat--the coping saw. Tiny teeth, unbelievably large amount of personal energy expended, beautiful and accurate cuts. (Source.)
Polycarbonate panels can be cut with power tools, but when using these any error you make can be exaggerated quickly ruining the sheet. We would recommend that you use a fine tooth pad saw such as the one below that is 14ppi and designed for plastics. (Source.)
hacksaw [or] light cuts [with bench tools]. (Source.)
Polycarbonate is cut and drilled with standard woodworking tools. Use a blade with 10 to 12 teeth per inch, such as a fine-toothed plywood cutting blade. (Source.)
[Polycarbonate] can be cut with common band and circular saws as well as with hand or power hack saws. Special blades are rarely required. Blade speeds and cutting rates are not so critical as with other thermoplastics because of the high heat resistance of polycarbonate. Special attention to blades and cutting rates is needed when sawing is the final or only machining operation, or when very thick sections are involved. [(I.e. over 1" thick.)] (Source.)
[Use either] a fine-toothed handsaw or jigsaw. ... Place the sheet on a stable surface and clamp down. Polycarbonate sheets can be relatively fragile so we recommend to use a timber block to cushion the impact of the clamp. ... Begin cutting. Polycarbonate is a material that is very easy to cut so you won't need to worry about splintering or cracking- just let the blade do all the work. (Source.)
Vad de flesta av dessa rekommendationer tycks ha gemensamt är användningen av något finjusterade skärverktyg, som kan användas för mycket hårda träkompositer som hård plywood eller MDF.
Jag antar att det förmodligen är vägen att gå. Tack för alla andra förslag.
(Bra prep, som att markera en bra linje och klämma på stycket, borde utan att säga. Likaså med hjälp av ögonskydd etc.)
