By doing the prep work yourself, and the painting afterwards, your proberly cutting your bill in half. Invest £20 in an angle grinder, get yourself a mask and thick welding gloves and get cracking. quote]
Also remember that if by accident the grinder jams it could throw itself into your 'T' shirt cutting through that and then slicing in to your stomach, this would result in a visit to the local emargency room where they will give you 4 stitches, some pain killers as its quite painful for a couple of days, oh, and a course of 3 tetanus injections.
I cannot remember where I found out about this but heh I also heard tetanus injections can really effect your memory!
