21 Turbo The Scrapyard Quadra

Then I decided to attack the bulkhead for some cleanup. The bit that holds the rack and coils was kinda awkward so I took it out, going to get that blasted.

Seamed around the top of the turrets after a clean too

Then flipped it over and went for it with the knotted wheels - the black staining you can see here is from the fire in the engine bay in the late 90's, which led it to the scrap yard I bought it from in '98.

Much better

State of me! What a mess.

Last day on the 21, I carried on the cleanup back under the car.

This brace across the transmission tunnel looked like it might be hiding some nasty so off it came

Cleaned up, treated

Welded back in

This is tough, dirty work... I was flipping between three different grinders, using one while the other 2 were outside cooling off.

The knotted wheels, while good for this task, the absolutely viscious. They shed the metal threads and the shoot off like tiny, stabby little missiles. Where to they go? EVERYWHERE....

Including in my arm! Ow. This is through the sleeve of my hoodie! I even had one whack me on the lip so hard it made me yelp lol. Obv I am wearing gloves and glasses, and I donned a mask for the dusty parts. I can still taste R21 seam sealer now haha!

Good progress overall over the xmas hols I think, especially with all the other car stuff I got done (and even something on the house!)
 
amazing work Dave. Real good progress. 1 point, As you know, I am not a pro, but I would personally rethink the seam sealer over where you have brazed. It just seems like an unnecessary water trap to me. But, like I said, that is just a novices observation that could be wrong. :)

No idea mate. I know no better than you lol
 
Isn’t the brazed joint basically old school seam sealer, effectively you’ve just seam sealer’d the seam sealer? Belt and braces approach.
doubt it would act as a water trap, pretty sure it’s a bonded screen so once the screen adhesive is laid I doubt it would make much difference to water flow in the area anyway?

p.s
I probably know even less

That was my impression of brazing. But you are probably correct regards to the water flow after the screen is in.
As you were :)
 
The brazing is a sealed joint, seam sealer isn't needed. But I'd always prime before any seam sealing. Most rust is caused from seams that are sealed at factory before any paint is put on the shell (other than the e coat). I always fill seams with as much rust primer I can then seam seal then I'll add any paint/stonechip etc as per it was originally.
 
Back on it again. Decided to takle this massive chunk of reinforcement across the back, it's a super awkward shape and I couldn't get behind it to clean and treat....so I hacked it off haha. It can go for a proper shot blast it's heavily rusted, but quite thick so it shouldnt need any repairs other than welding back on.

Glad I removed it, it needs a good work over under there.

Got stuck in to it, lost another chunk of skin to the knotted wheel!

Decided to stop cleaning up when my arms were ready to fall off and I was fed up of tasting rust lol, I was low on BH Hydrate 80 but hoped i'd got enough to coat what I had gone over...

This took longer than I thought, working the Bilt in with the brush properly.

After/Before - quite a difference.

x20210117_172620_RS.webp

I ran out of time to let it dry and prime it, i'm going to brush on the primer underneath, as 1)it'll be thicker, 2)I can get into the tight spots better and 3)I'll be gravitexing over it anyway so finish doesn't matter. I may try and do that one evening so it dries before my next weekend sesh.
