More of the underbelly

This round was mostly an effort to clean off the grime and then treat any rust with POR-15.  Not to complicated or time-consuming.

First, I ground down some of my old booger welds from previous patch work.

And then I went after the rest of the belly with a wire cup on the grinder.

This area had an issue that I hadn't noticed before.  There was a bit of burn-through where I'd welded the rectangular tubing  down in place of a rotted hat channel.  So I ground it smooth for a patch piece.

The patch piece was just some flat stock bent in a vice.  Then, like I've done before, I burned it in a bit and then hammered it to fit the contours of the area.

If I do say so myself, my booger welds are improving.  I'm getting better at drawing little circles with the torch tip and moving the puddle at a consistent pace to keep the "bacon sizzle" sound going.

Ground smooth.

Another small patch in the passenger's floor.  On the right in this pic you can see the underside of the passenger step.

Shiny.

POR-15 time.  Note that some areas are already starting to blacken.  A good sign since I can't get all the rust given the tools and the patience with which I am saddled.

Lots of surface rust in need of conversion.  This is part of the firewall and where the fender mounts.  There's a crack along one of the seams that'll need my attention next week.

Just about done.  I won't get all the rust off the belly or from the hat channels, but I'll get enough to keep the rig from being structurally compromised, which is all that really matters.

This is the underside of the transmission tunnel.  It's knackered in some spots, but I'm not sure what modifications it will need until I get it back over and on the chassis.  So the rust treatment is just for now.
