Well after work I stopped by our local steel and Ali merchant (not the one we use at work) and got 3 x 1.5m lengths of 25mm x 25mm 10g Ali then went to B&Q and got an 8 x 4 sheet of 18mm MDF which they cut down into manageable lengths. Liberated a couple of 1.2m lengths of 3/4" medium red band pipe from work today (we haven't used it for 7 years) so this weekend unless I get collared to do DIY I'll be marking out and cutting out bits for the cheap crappy router I'm doing ;)
