The rust had even extended onto the engine bay skirt where the tray joins.
Not a real hard repair for alot of people handy with a MIG & basic power tools, some usually take the opertunity to replace it with a flat panel & smooth the rest of the engine bay. I like the factory look of LH engine bays with all the lumps, creases & flat black paint, so my mission with this car was to make the repair as original & undetectable as possible. To start off the mission, the rusted tray had to go. I cut around the edge with an air hacksaw & cut off wheel taking care to avoid the spot welded flanges, then chiseled away what was left of the factory spot welds.
This car had been in a minor hit to the L/H/F corner at some stage in it's life & although the chassis rail had been pulled straight, there was still evidence of damage to it. It's a little hard to see in the photo, but it was there & needed to be addressed.
With some help from my mrs, i planished out the minor dents & kinks in the rail. A quick sand & hi-fill & it will be undetectable.
Next step was to fabricate a repair section for the engine bay skirt.
Repair section almost finished.
Clamped in place, i scribed a witness mark around the repair section, then cut the rusted area away.
Tacked in place. Once fully welded, i could get easy access to both sides to finish off the welds nice & smooth.
Next step was to clean up the areas the new tray needed to be welded to, apply some weld thru primer & treat any surface rust.
Then it was time to power up the invertor spot welder. With the new tray clamped in place, this was the easiest part of the repair, spot welding it to the car.
So far, so good.
A quick coat of etch primer & flat black & the repair is finished. Eventually i'll respray the whole engine bay, but for now i'm pretty happy with how this repair turned out. Next repair is another common area for Toranas to rust, the lower beaver panel under the rear bumper.

I've been advised that you can hire them, i don't who you could ask though. I don't think it has to be a three phase invertor like i used either, i'm fairly certain because you're welding 1mm thick panels together, a single phase spot welder should do the trick. Try Hare & Forbes, i think they're close to you around Parramatta/Northmead & they could probably advise you better in this area than what i can. The key to using them is both sides of the panels you want to weld have to be super clean. Any traces of rust, paint etc & they will arc & burn holes. Clean both sides of both panels & apply a weld thru primer to the surfaces that will join to each other, leave the contact areas for the spot welder tips bare steel. You can single side spot weld these panels, the key here is to place the earth lead on the secondary panel, ie chassis rail, & spot the first panel, ie battery tray. If you earth the welder on the same panel you're spotting, it'll arc & burn a hole. Also, use vice clamps close to where you're welding, both surfaces have to "butt up" close or you'll burn holes. Hope this helps.
Cheers Matt

What's the best weld through primer to use?

Replacement engine is back from Hercules Competition Engines after Ned Sassine gave it his magic touch. Ned is one of the most down to earth honest blokes i have ever met, his knowledge & expertise was second to none. I highly recommend anyone planning a performance engine build consider talking to Ned.

I've also been amusing myself with prepping & painting odds & ends in between working on the car itself, weather permitting.
I'm not after a top ten show car finish, just want it neat & presentable so i'm happy with my work so far.

I don't know how you find the time to do all this work, I'm struggling just to drive my cars.
Cheers Mick.

hey mate excellent work. be a sweet ride with the v8 in. what did you use to prep the under side.........
Thanks mate, i used a heavy duty truck degreaser & scotchbrite, jacked it up as high as i could & hosed it off to get rid of the bulk of the grime followed by a citric based degreaser & cloth rags to finish off, then P320 to "key" it for primer/paint.

Found some more rust to repair, probably next weekend if it doesn't rain.
The rain held back today so i was able to repair some minor rust that was coming up behind where the bonnet hinges bolt to. Thankfully it wasn't too bad & after doing the initial exploratory cuts found i didn't need to unpick the reinforcing plates.
