How do you eat an Elephant? Same as
when restoring a rusty TR3. One bite at a time! This is a rusty
section of the left firewall bulkhead, with the indentation for foot
clearance near the headlight dimmer switch. This is not a simple panel
to make and new replacements are not available, so we'll repair just the
rusty part and move on.
The process to make a part like this is
always the same, and it takes a bit of time to do it correctly. After
removing the weak and damaged metal, a pattern needs to be made before ever
picking up the snips. If the pattern fits, then the replacement part
has a better chance of fitting too!
Starting to come together now. We start
with the most intricate shape and work out from there, saving with the
simpler (flatter) sections until last. We always make the outer
perimeter slightly oversized, and trim to fit the opening once it has been
test fit (multiple times) on the car.
Here is the new repair panel, tacked into
position and ready for final welding. People always assume that by
doing Triumphs exclusively, we should be able to provide accurate cost
estimates for routine jobs like replacing floor pans. But as you can
see from all of the repairs that have been made to adjoining panels, it's
never as simple as 'just' replacing the floors, and the cost to do so
will vary greatly from car to car. We just have to fix all of it, one
bite at a time!

Minor frame rust can often be repaired if it
hasn't weakened the structure. This is the area where the handbrake
handle attaches to a TR3A frame, and sandblasting has opened up a few weak
areas that could use some attention.
Digging deeper into the frame and cutting
away the weak looking spots revealed the extent of the damage, and the crud
that sandblasting was not able to remove. All of this remaining crud
would act like a sponge, and hold water against the already weakened metal,
accelerating the rust process in the future. Good thing we got it
cleaned away now!
Here's a peek at what was hiding inside.
We now have a opportunity to clean all of this up, and coat it with a good
rust encapsulating paint to stop additional deterioration.
Frames were originally constructed from heavy
gauge sheetmetal that was bent and formed for additional strength. As
long as weak areas are replaced with the correct gauge (thickness) metal,
and fully welded to solid metal surrounding the repair, the repair will be
every bit as strong as the original frame was when new.
