Gday peeps, am on the scrounge for as close to a whole sheet of 16mm plywood as I can get but will accept pieces bigger than 75cm x 75cm. Im building a massive speaker box. Im located in Townsville so if you have or know of some scrap 16 - 19 mm (pref 16 - 17) in a shed some where then drop me a line and I'll be happy to liberate it for you. Cheers.
