Have had a couple of machineing jobs this week so only got back on the welder this afternoon, i have 2 of these to send to colchester there towing dollys so tractors can pull artic lorry trailers. Went to the scrap yard and amputated the donor parts, cut the rear off an old 40ft trailer, turntable plate came off a volvo, brake cylinders will be sent and overhauled, and hydralic brake valves also added so we have a duel brake system. once the dolly is built it will go to the shot blasters then paint shop. First job is to shape out the drawbar with the plasma, 8" UC is used on a 3/4 wall, I take no chances with the strength you could have 20 ton being hauled at 50Kph. The hook end is heated and clouted to give it a nice strong V. The hook is shaped into the UC so i can weld it on all sides. 3 passes should do it, cross plates are next in line, but i am haveing the weekend off for a change so will post some more pics up next week.
