Yea by the looks of that part of frame doesn't seem like much there to work with beyond taking that section out.

It looks like he is replacing that part of the frame. And he is doing it off the body which is great.

I am going to cut a couple holes on top of frame to remove the debris…then blow it out with air before rinsing interior of frame with rust treatment..the worst area at the left rear will be replaced completely,,which will be a bit tedious but i work cheap.

If you had one of those 2000W laser remove rust and junk from metal, the clean up time would be minimal for everything and the metal would look like new. Even those wood barnacles would be vaporized.

One of our Yanmar tractor owners bought a machine as a retirement income. Takes less than a few hours to do an entire vehicle.
A few jobs and the equipment is paid for. Here is his website. The laser even does antique furniture stripping without any chemicals or sanding, leaving behind the most wood possible.

It is super amazing how a laser can clean in the tightest and multi surfaces area where only chemicals were used prior.
Classic vehicle restoration is now a huge leg up.

When you remove the hidden rust, how much steel is left? I think you would be betytert off in the long run to build a new frame. The original is relatively straight without a lot of curves.

Nice project Jazz looking forward to your progress.

This is what we run into at work all the time. Not on vehicles but frame works for installations. By the time you blast it and beat scale off how much of the original metal is there?

With laser, more of the metal is retained. It's only doing micron surface etching. And the etching is so fine, when you run your fingers over it, it's baby skin smooth.

I've done angle grinder wire discs, wire-wheels on drills, wire brushes, and there is always a chunk area of metal removed in a deep area.

It a laser finds a soft spot area of metal, then you know no other method other than replace and patch weld.

Cut out steel till it’s all correct thickness. One pinhole is a 16” X 2” hole now. I’ll also remove some of bottom plate to reinforce any patches on side rail of frame
Bottom plate is riveted on. Picked up a little piece of scrap to start patching

I don’t have a mandrel bender or a jig for frame building. Repair is easier and will be stronger than original.
