How can you cut 1" acrylic?

[bmilam]

Ok , this may be a silly question, but how can you cut a large sheet of 1" thick acrylic?

[scrager]

same way you cut a 1/2" thick piece. table saw or router. it's just going to take longer and be tougher on your saw blade.

if you have a waterjet, you could probably cut it with that too.

Damn.... I left my waterjet at home today

what kind of saw blade do you need. i know the wood ones are about 64 teeth to a blade but is the more teeth the better for acrylic? thank you for the information.

[jrandreassen]

The more teeth the better....
At least that's what I heard.
I use a 130 (I think), it's a trim blade.

You really need a plastic blade at thickness over 1/2" if you want any accuracy to the cut. The alternative might be step cutting it but, thats risky as well. Depends how much you have to cut and what the application is to determine if it's worth forking out the $250 for the blade. Nothing beats using the right tool for the job though.

When I have to do thicker stuff, I rough cut it with the saw, then I polish it with the router.

I have always had good results with a 80 T carbide blade. If you dont spend a little on the blade, you are going to spend a lot more if you screw up the acrylic and with it being 1 inch, that isnt cheap.

thanks for all the help guys. i was just wondering because i have been to the plastic shop alot and got a lot of acrylic from them and kind of overestimate and underestimate and had to buy more. i only use 1/4 or 5/8 max. thickness so now i have a bunch lying aroung and thinking of building another sump. just trying to use what i have so i dont need to buy anymore. too bad the shop won't cut it for me. they said if it leave their hand. they don't want to be liable. but thanks for all the help.
