Some progress on the left door of my TR7. I've plugged a few holes in the edge with weld, thanks to advice from Bump and some old copper pipe from my father-in-law: Some of the holes are too large to be plugged, so I've had to start patching. Here's some pics: I messed up the left edge, so I cut another patch. This was slightly too short, so I clamped a piece of scrap steel behing the gap and filled it with weld, before grinding off the scrap: Here's the other side after dressing with my angle grinder. I'm pleased with my first attempt at welding in anger. Some things I've noticed. Should I be able to push the wire in slightly at the tip? I've noticed some soot kicking about. Is this from the old metal? I definitely need more light in my shed. My helmet seems to cause a shadow wherever I stick it.
