Hi Azazello. Thanks for your 2 cents worth. I have looked and i can get one for 100 to 150£. How easy is it to do? I can practice on some bits , yes. The weld is under the carpet so does not HAVE to be perfectly beautiful. But I would be happier if it looks competent. I am dextrous. I can see welding from the top is possible. I think welding from below may be very difficult - don't have a lift or a pit. Can I stand in the car as I weld it, is there any possibility of getting a shock, because there is an earth clamp on the car. If you can give me some pointers I may get the confidence to give it ago.
