Finishing up the floorpan

This week I'm finally finishing up the structural floorpan work.

First thing to do was to weld up the holes used for the Cleco pins. As these holes were also to be used as plug welds to hold the pan halves in place they were first drilled out to increase their diameter.

This handy tool is a copper sheet with magnets in each corner. It's used to place behind open holes when welding. The idea is that the sheet gives the molten welding material something to lay against and, being copper, the weld does not stick to it.

With the pan the right way up and the mig out I took the opportunity to weld up the holes in the framehorns, left when I removed the heater control conduits.

Plug welding the holes using the copper sheet in place underneath.

The pan was then flipped over to finish the welds on the underside nicely.

Here you can see a hole in the chassis spine that I'd not  yetwelded up. Visible through the hole is the copper sheet prior to welding.

Welds underneath completed.

Last bit of welding was the rear of the pan halves to the torsion tube housing.

All welding completed, welds cleaned up and primed.
