All plug welds punch and was about ready to start welding this on
IMG_7123.JPG
Then I remembered there was one more loose end to tie up. Had to repair the lower corner of the suspension flange with some heavy gauge.
IMG_7124.JPG
All set. The end of the new flange has to have something to hang onto. Also cleaned and remove the remains of the old "K" brace on this back corner.
IMG_7125.JPG
I can finally begin welding this on.
IMG_7127.JPG
Plug welded and finished out the joint along the bulkhead.
IMG_7141.JPG
Sticking with my plan I'm going to leave everything ahead of the bulkhead wall loose until I get the front beam squared. That set screw at the front will have to do until then.
IMG_7142.JPG
Joint seam along the bulkhead finished out smooth. Onto stitching up the joint along the new lower flange. That next; Going to be a long one.
Thanks for looking.
Justin

IMG_7167.JPG
This forward corner of the cockpit weld finished and completed. Gas weld detail at the leading edge of the bulkhead flange replicated along the way. This small portion ready to accept a new floor pan. Small area but it was a win that day. Moving rearward to continue the rest of this flange repair.
IMG_7185.JPG
The rest of this run welded up and dressed. Lap joint details replicated carrying over the lines.
IMG_7186.JPG
Same treatment for the backside.
IMG_7187.JPG
I'll close and add the new gusset floor once the front beam issue is addressed.
IMG_7188.JPG
Another mock up with the new closing panel just to see.
IMG_7189.JPG
Next section runs the entire length all the way back under the heater tube elbow and embossment detail. However, the new replacement section isn't that long which is just as well as there is a lot of work ahead to repair in and around the elbow.
IMG_7190.JPG
I'm going to the make the break under this outer lap joint. A perfect place to quit as it will be concealed and supported under this lap panel.
IMG_7191.JPG
New section overshoots this eventual joint by only a couple of inches so its almost the perfect answer.
IMG_7192.JPG
Original flange(X) is the same width as the standard issue back here so all I need to do trim away the excess.
IMG_7193.JPG
Like before cutting just at an inch above the flange line. This portion is actually still good all the way down the flange itself but its got to be weld repaired somewhere so I might as well keep the repair uniform.

IMG_7194.JPG
Saved as much of the original vertical wall as I could.
IMG_7195.JPG
Section removed after carefully cutting around and breaking loose from the bulkheads. Prepping new section to fit next.
IMG_7196.JPG
New section cut to basic length for a flush fit.
IMG_7197.JPG
Now positioned for needed flange height.
IMG_7198.JPG
Ready to etch my final cut line in and trim.
IMG_7199.JPG
Cut to final width and clamped into position with a good tight joint. Begin tack welds.
IMG_7200.JPG
Securely tacked
IMG_7201.JPG
The end shape trimmed to continue that Delta-V relief shape.
IMG_7206.JPG
Quick paper template as now is a good Time to fill that hole.
IMG_7208.JPG
Lap patch all welded and dressed.

IMG_7210.JPG
Its subtle curve and flange shape made for a smooth transition between the two flange widths.
IMG_7211.JPG
Inside view of this repair.
IMG_7212.JPG
This area about ready to accept a new floor pan. I'll finish stitching up the rest of that run a little later on...
IMG_7214.JPG
as I'm going to switch gears and get back to finishing out this corner repair I started with.
IMG_7215.JPG
more on this next...

thanks for looking.

Thanks once again Antione.

New door well tray/floor installed.
IMG_7223.JPG
Just about ready to tack this in. I wanted to as much of that secondary wall as I could but as it stands now its in my to get a clean shot at the most inner part of the weld joint so no choice but to cut a little higher or lower in this case.
IMG_7224.JPG
Wall trimmed back just enough and began stitching it in.
IMG_7225.JPG
Nice getting more structure back in there.
IMG_7226.JPG
Begin template for the new inner splash pan/closing wall.
IMG_7228.JPG
Flange of the new pan will eventually join onto it. Ideally I would have had the weld joint run through the middle of this flange to both conceal and support it but the rust went just a little higher on this one.
IMG_7227.JPG
Eventual wall patch should butt up nice and tight against the new pan.

Secondary closing wall repair patch.
IMG_7242.JPG
Able to use the remnant section left over from the front bulkhead wall flange repair from earlier.
IMG_7243.JPG
Folded and trimmed to basic shape.
IMG_7259.JPG
Final trimming and shape all but there.
IMG_7260.JPG
Final trimming on that butt joint eventually dialed in with plug weld holes punched. Ready to weld. Very tricky patch as the flanges come in at specific angles and the wall itself has a slight lean to it making dialing in all the lines for a clean fitment all the more difficult.

Secondary closing wall patch continued:
IMG_7261.JPG
Would have been impossible to repair this area cleanly with the hinge boss in the way.
IMG_7263.JPG
Getting ready to weld that inner vertical flange section from the outside. Loosened the rest of it up to ensure a tight fit. A lot of planning ahead had to be done as its almost impossible to dress any weld slop down in that deep corner.
IMG_7268.JPG
New secondary wall pretty much set and dressed. Had a really hard time reaching down into that corner but going to leave well enough alone for now.
IMG_7279.JPG
Onto the new end cap. A little tougher to work with 18 gauge but now that I have it on hand I want to try and make most all "chassis" related components from this instead of 20 gauge.
IMG_7280.JPG
Cut to basic and slightly oversize shape.
IMG_7283.JPG
Rough mock up with the new longitudinal section to trim back a little closer. That new simonsen piece is made of 20 gauge which I'm not really thrilled about being such an integral component of the "frame" but we have the triangulation of the roof so it should live.
IMG_7284.JPG
I will however reinforce it where I can.
IMG_7285.JPG
Begin rolling in that curved leading flange detail.
IMG_7286.JPG
Final trim and shape along with all the plug weld holes added. Ready to mount for the final time.
IMG_7287.JPG
Carries on the flange line from the OG section.

Splash pan repair continued:
IMG_7288.JPG
Inner wall and overlap details carried on here as well.
IMG_7290.JPG
One more test with the long just to make sure before I started welding.
IMG_7289.JPG
I'll add in more plug weld holes before I join these together for the final time.
IMG_7291.JPG
Begin Plugging and stitching it on.
IMG_7298.JPG
Fully welded and dressed
IMG_7299.JPG
Relieved to have the heavy lifting completed in the confines of this corner.
IMG_7300.JPG
Marking for the eventual spot weld details and the final splash pan patch overlay after the longitudinal cavity is fully welded and all closed up.
IMG_7303.JPG
Gone as far as I can up here for now.
IMG_7293.JPG
Onto the back half next. Should be fun.
Thanks for looking.

Began planning the repair in and around the heater conduit.
IMG_7301.JPG
While this rear closing wall is in mostly solid shape it is in my way.
IMG_7302.JPG
I hate to disturb it but its going to have to come out to get a clear shot at the end of the tube.
IMG_7310.JPG
Cutting just enough of the rear closing wall free for now.
IMG_7311.JPG
Hated to do it but things got immediately accessible. I'll get the rest of it out later.
IMG_7312.JPG
Begin peeling this onion by carefully removing each layer of steel or at least what is left for info and templating purposes.
IMG_7313.JPG
Bottom outer embossed layer which is directly welded to the end of tube cut free first exposing the second layer.
IMG_7314.JPG
Carefully removed the remains of this second layer. Again for copying purposes.
IMG_7315.JPG
What is left is the remains of the inner most flange/wall run that welds to the end of the inner exit tube section. To the right of it are heavy gauge angle flanges off the torsion housing that were beefy enough to have just survived. I think, I'll know more once I start cleaning this area up.
IMG_7316.JPG
Inside view that inner most wall and as you can see the rot runs deep.
IMG_7317.JPG
To get a clear shot all of that will require the elbow of this conduit to be removed. No surprise of course.

IMG_7318.JPG
Taking it right at the factory weld joint.
IMG_7321.JPG
Tube section free.
IMG_7322.JPG
exposing more of what lies beneath :shock:
IMG_7323.JPG
This is really cutting deep and though I've got the roof and a sub-frame Jig in there I still got a little spooked so I added that tubular bridge strut there just to make sure it did begin sagging. A lot of leverage running through here with the weight of the body hanging off each end.
IMG_7324.JPG
Sort of hard to make heads or tails of these crispy little guys but since I watched it come apart I think I can still reverse engineer it.
IMG_7319.JPG
So gratefully just to have those rough examples because as you can see that information no longer exist on the left side.
IMG_7320.JPG
It turns out the side I'm on is the "cherry" side. A perfect example here of being at a total loss without an original reference.
A couple more layers to go and would be touching bottom on this repair. That next...

Thanks for stopping by.
Justin
