welding steel base or just getting aluminium extrusion

[cropwell]

was ordering the steel from metals4u.co.uk cut to size, i forgot to ask that question as well so thanks for that boyan, I do not have access to a welding table and i do want to try and keep the cost down so what would you recommend welding the frame on? i was thinking of doing a cheap wooden frame and make sure its level and use a sheet of mdf on top for flatness

Reefy, have you tried Nottingham Steel at Colwick, they will cut to size and they are probably cheaper !
Weld UK at Pinxton have got some heavy duty clamps at £60. I called in in person for one and asked how much they could do two for cash and it was a good discount !
