Hello everyone. This is my first post after lurking for a very long time!
I’m planning my first welding project for ten years or so and could do with some advice. I’m planning a chassis jig for my MGB’s restoration. The driver’s side front rail needs replacing as do the sills, castle rails and crossmember. The rear spring mounts are also pretty shot. Older restoration attempts look fairly dodgy and botched. Basically, even doing it in stages, there's going to be a lot of the underside being replaced and I want to make sure everything ends up level, sqaure and in the right place – hence the jig.
I’ve read the useful stuff on the web-site and will mirror the Renault 4 / Datsun jig covered, but want to take the advice given and use box section from the off.
My MIG welder is a Clarke 150 Turbo. Its ten years old and needs some TLC to get it back to top condition (liners, new wire etc.).
I assume box section is the best material use but what size and thickness? The jig will measure 3.8m by 1m and will be supported as required to keep it level. I don’t want it to be so heavy that its impossible to move. 50mm square with 4mm thickness seems readily available locally, but are the box dimensions too small? What thickness could my welder reasonably cope with?
Any thoughts gratefully received.
