In what is the first real consumable purchase for the project, other than the plans themselves, I continued to get quotes on 1 and 3mm HIPS plastic. The best that I found, and ultimately bought, was from Australian Sheet Traders in Canningvale (ph 9-456-1004, talk to Wendy). I ended up getting the 3mm 2400mm x 1200mm for $66.70 and the 1mm for $22.20, which made it about 20% cheaper than the other mob I first enquired of. I also bought a 500mL can of Acri-Bond (which was recommended for Hips on Hips bonds) and a metal needle bottle applicator for a total of $28.00. They threw in a couple of pipettes to transfer the adhesive from the can to the bottle.
I went to Bunnings and bought an Olfa Auto load PL-1 cutter for $31.90 and a 4mm router bit for $26.10.
With that lot, I am now ready to go with the initial stage of adhering the plans to the plastic, rough cutting them off then using the Router table I have made to cut the curves correctly. Hopefully the next post will be of me actually getting going
