G’day. My comments on cutting perspex/plastiglass were based
on experience of 20 years ago, when I ruined some expensive
sheets of 1/4" clear perspex using the score-snap method, and on
specialist advice, bought a circular saw designed and made for
the job (it cuts rigid PVC sheet perfectly too)
Having been taken to task over those comments I made
previously, I have just been to my workshop where I have some
spare 1/8 perspex sheet. Using a tile cutter (which has a sharp
tungsten carbide point like a pencil) I scored a piece heavily
three times , then snapped it perfectly over the edge of my
bench! Annoying, eh? Why it was disastrous for me 20 years ago
I really don’t know: I’ve never had any problems in cutting up
to 1/2" glass, even, and have done a lot of cutting 1/4" and
1/8" glass. But there it is; I gave you all a bum steer and am
suitably ashamed. Mea culpa!! And that hair shirt is damned
itchy. Red-faced, johnb.
