Thanks for the replies guys.

cncJim, yeah I did watch the video but that seems quite hard foam like njhussey v28 foam.

I really need the laser to do things like this http://www.lasertouch.com.au/Foam/fi...mage_0_544.jpg as this is the primary purpose of the machine which I think a saw wouldn't be able to do?

GEOFFREY, if a laser isn't powerful enough I could do 2 55mm and glue them together but I thought there would be lasers strong enough?

Cheers!
