Somone was asking about a stand. I built a repair stand at the weekend for about $20. Its 30mm box tube with a cheap 'G' clamp for holding the top tube. I cut a 5" peice of scaffold tube lengthways then hammered it into a larger circumference (about 4 hits with a 2lb lump hammer), welded one of the peices to the clamp (the bottom but this would normally be the top as its inverted) lined that with a firm foam and used the other half of tubing lined with foam on the top of the tube. THis way it hold it as firmly as you like without doing any damage or costing you any real money. Granted it dosent adjust but the last time I I looked I hadnt grown much since I was 18
If you get down to a home depot or some place, get them to cut it for you so everything is square it will take you about 30 mins to weld up (or the guy at the gas station for the price of a beer 1 can of spray paint laying around the garage and its done!
