Pedalboard parts (in Britain)

[Jode]

I'm currently getting myself together to build a pedalboard, but I'm having trouble tracking down a couple of parts... so if anyone in Britain, or better still, Glasgow, knows where I can get the following:

- a hinged handle to screw onto the underside at the back, which is sloped.
- metal corners for reinforcement.

I realise this is a bit hopeful, as these things tend to be found in wee hardware shops, but this place always surprises me pleasantly
