Thanks guys. Still catching up. Got out the trusty yellow paper and started making templates to fill in the hole in the firewall. There are two pieces. One inner that runs across from the a pillar to the bonnet hinge.
This was pretty easy. Just had to cut around the tabs I left for the bolts.
Next the outer skin. A few tricky bends will be needed here. There is a little bit at the top where the plenum meets the grill. Going to have to do this as two parts.
Yellow paper and blue tape is much easier to deal with than metal and welding. Worth spending the time making things up.
So inner panel first
Only needs a small radius bend on each end. Final trim and fit was a combo of tin snips and power file.
Had to weld from inside to keep the face where the two pieces are sandwiched together on the firewall side clean and lump free. Welding looking up. Now there’s a fun job. Welding jacket and fireproof blanket over my legs kept me toasty warm
Outer skin. Quite a few little subtle bends and radius’s to get to to all line up with what remains of the firewall.
Paper template saved the day and my sanity. Little top bit sitting in place. That took the longest- this one was a second attempt. Here’s the two parts welded together.
Holes drilled for plug welds. Screwed it in place to pull the two pieces together and started welding.
And run out of gas.
C size bottles just shouldn’t be available to tight arses like me. Had to go the cheapest option.
Anyway ended today with a trip to the hardware for more gas and managed to get the first round of welding in. Woot!
Bit of weld/ grind on the weekend and think I can tick this off.
Now back to the sill where the subframe meets. This looks like it has had a rust repair in the past. Missing some metal. Missing even more once I gave it a cut and grind.

Now time to bend some metal. I have a new bracket for the RHS already so used this as a guide. Its 1.5mm thick. Bit of hammering with a piece of hardwood.

Lots of little tweaks later I have this.

Drilled a couple holes to plug weld the new piece to the thick plate inside the existing bracket. The rest is butt welded. Also welded up the existing patch to the inner sill. Think my welding is getting better, only a few spots where I missed

Gave it a grind over the area where the chassis joins on to the inner sill.
Bit of time travel. Did this before the sill but forgot to post.
So when I cut out the floor realised that the chassis was rotten where it joins the sill. Welded a bit of square rod to hold everything in place and to use as a reference point. Took loads of measurements.

Weapon of choice.

So used my sheet metal bender to fold some 90 degrees. 1.5mm requires a bit of force.

Hardwood and big hammer does the job.

Final fold. Lucky for me the sheet bender is made up of 50mm angle. Inner size of the piece - 50mm. Makes life easier.

Decided on a bit of bling for the drain hole. Got out my 36mmand 27mm sockets. Wound up the vice whilst tapping on the end of it.

Looks the part

Here's the final piece. With drain hole. Ready to weld in next week.
Great Job Scott,
Love seeing your approach to the metal work with what appear to be some basic shop tools but plenty of thought & preparation. Thanks mate.
regards
Stephen

Nice work. Ripper vice.
That vice has some history. My grandfather made it when he was training to be a fitter and turner back in Glasgow. He must have been happy enough with it to ship it when he moved to Australia. It rotates 360 degrees on the table and 180 at the jaws. He did a good job - it has stood up to a fair bit of abuse.
So the chicken/egg moment. Can't test fit the piece unless I cut it to fit. If I cut it too short I'm going to have A/. fill it with weld or B/. make another piece to fill the gap. Much measuring later I got this.

Bit of a gap on the left side so I went with plan C/. and re-bent the 90 degree tab on the left so it is a couple mm smaller. Still had plenty of meat to drill the holes for the plug welds so all good. At this point the battery in the phone died so no pics of welding it in.
Here's one of the job done, once I ran over everything with the powerfile and wire brushed a bit of the inner sill, looking for rust.
Got a pair of front floor repair panels. They look like someone put a sheet of metal over an existing floor pan and hit it repeatedly with a hammer. All the edges are soft and the channels don't go as deep as the original.
So out with the tools for a bit of reshaping.

Before I can fit it - need to straighten out this a bit.

So jacked under it and hit it with a mallet. Not much weight left with the doors off so in the end I sat in the car and bounced it as I hit it with a hammer.

New floor screwed down over old floor and cut with a 1mm cut off wheel, and a dremel in the tight places.
