I have just fabricated a selection of sheet benders from 600mm to 2000mm width as a means to use up some of the excess material in the workshop (never scrap...tight git) as a result I am now in a position to cut and fold ali side panels quickly and accurately if any one prefers to buy them than risk knackering their own ali, or if you are in the Worcester area you are welcome to use the benders on your own material. I dont know what the cost will be yet as I have not priced the sheet, I got mine gratis but I can't go into that! will post details on my site asap http://locostbuild.tripod.com
