I posted here a while back when my glass bed failed. One of the suggestions was to replace with Garolite or G10. My sheet finally arrived and i set about cutting it down to size.

…

Within 4cm, my basically unused jigsaw blade was worn flat, and by the end of the first cut (20cm), there is basically no more teeth.

For the second side, I tried using a multitool cutter, and within a few millimeters it was visibly blunt (plastic and metal tools). Finished it off with a standard wood hand saw, which seemed to go better.

So warning to anyone considering garolite, dont use power tools, it will fuck them up.
