Paint stripper, elbow grease and more tinworm terrorism

Had an hour or so in the garage and decided to expose some of the factory panel junctions ready for removal and replacement with new metal.

I used some chemical paint stripper, a scraper and a steel brush along with a large jar of good old fashioned elbow grease.

It's much easier than a bastard-wheel on a grinder, gets into all the tight spots and lets you see exactly where to remove spot-welds & seam welds etc. ready for fitting new panels.

Why do later bugs have so much sodding seam sealer in all the nooks and crannies? it's not like it ever actually worked - just gave hungry tinworms a nice cosy place to set up home.
There's a small tinworm town right there look!

Hopefully the seam sealer I'll be using works better then the old stuff....
Anyway, with the spot and seam welds visible it'll be a piece of piss to accurately remove the heater channels and bulkheads.
Sweet.

Rust never sleeps, starting work on Tom's Baja

STOP! Baja Time.
It's been nearly four years since we first set about building Tom a Baja.
The car we used was very good for its age but did need a few repairs at the time.
There were also some areas I just couldn't be arsed to do, like the floorpan and bulkhead etc....
The car was not going to be road legal so we just went offroading.
That was then.

This is now.
I'm not getting any younger so now it's time to do it right, road legal.

Matt & John came for the ceremony and we unbolted Tom's Baja from it's floorpan.
I say "we" but Matt and Tom did all the hard work while John and me offered sage instruction and smoked fags.
Well, we have done it all before and thought we'd let the youngsters learn the way of the skinned knuckle.

The floorpan was even ropier than expected, good job it's not needed.

Just as we thought, the entire bottom of the 'shell needs repairing.
Both heater channels, whilst very solid are shot at the ends so will be replaced.
Front and rear bulkhead areas have the appearance of swiss cheese so they'll get a dose of the same treatment.
It's a fact that no two bugs rot out the same, near perfect heater channels except for real bad rot on the front and rear ends - spooky!


On the up-side, the bottoms of the door-posts and b-pillars appear perfect where they join the heater channels.
Both rear quarters are solid as well so there's a good few jobs saved.
The few repairs I did when we first built it are still sound and won't need doing either.
Good times!

As we've done all of this before on Matt's Baja I won't go into too much detail but I will hopefully have a few new tricks up my sleeve.
Lessons learned from the first "resto" should help speed progress too.

First job - brace the bodyshell
I decided not to brace the door openings in an X fashion like we did on Matt's car - with hindsight it was great for stopping the door opening going out of shape but no use for keeping the width of the car right.
This time round I have built a frame inside the car that braces both side to side (transverse) and front to back.
I intend to use the transverse braces as reference members for heater channel replacement - I'll put a long piece of box section or similar under the channels and measure up to the bracing to get the height and alignment just right.

I don't like tack-welding to a perfectly good panel only to hack it off later (and have to refinish the area) so I used the seatbelt anchor points at the b-pillar.

No such nifty tricks at the front, though I did consider using the door-hinge fixings but decided against it as the fixings can move up and down for door adjustment - bad for a brace/reference member.

Hopefully the bracing will allow me enough room to replace the heater channels comfortably.......fingers crossed.
Soon be breaking out my old mate Mr.Bosch and removing some metal!

Finished welding Matt's Baja

It's done!
We tidied up all the little jobs and the welding is now complete - YAY!!

The bottom corners of the windscreen surround needed work, so we robbed a section from the old roof I saved - the rear side window aperture is just the same profile so we used a bit of that.
Man-John's idea and a very good one at that.

Very tricky to cut this bit out and not damage anything else

Managed to make a decent enough job all the same, just a little bit of weld "filler" to dress back.
Matt's having a go with my favourite fettling tool, die grinder & tungsten carbide burr - cuts through weld like cheese.

A quick lick with the flap-wheel and we're done

I'm quite chuffed with this repair

Did the other side as well, not so pretty but the donor section wasn't so good.
That's my excuse and I'm sticking with it.

We had to let in another large piece of gutter, we used every inch of useful gutter from the donor......very tedious.

We also did the other side of the bonnet line, more butt-welding :)

Sprayed with galv' paint, sweet.

I'm glad that's done, there hasn't been any part of the bodyshell left untouched.
We've replaced or repaired the bottom few inches of the entire car and plenty more besides.
I've enjoyed it though, I've learned some valuable new tricks for the next one.

Next job is to get Tom's Baja body removed from the ropey floorpan it's sitting on, we'll use Tom's 'pan to move Matt's bodyshell back to his gaff.
Matt's going to slap on some filler, some primer and a nice top-coat......looking forward to having a test-drive.

A few weeks rest and we'll start on Tom's Baja, I'm sure there will be plenty to do.
When Tom's is done it's going onto the Semi 'pan.........

Confused?
