Is there any reason you don't have a 'proper' spot welder given the amount of plug welds I've seen in your build threads...  Are they expensive? I was given* one by my father in law.

They are generally expensive and you would need to load of arms to make it capable of doing the factory welds in places.

I just don't like them to be completely honest with you.

 

When i worked at vauxhall, we had no choice, we had to use a spot welder to replicate all factory welds but now i have a choice, i opt for plug welding. i trust it more.

Plus, as Jordie said, the arms would only reach certain areas so i would still need to plug weld alot of it anyway

Today has been bitter sweet really.

 

On one hand, progress has been steady but on the other, a problem has been found with the other end of the heelboard so now both ends are going to need replacing.

Unfortunately, the rot was hidden under sealer on the outside and behind random skins of metal (which i believe to be parts of the old inner sill) on the inside.

 

This has set things back quite a bit as i have had to spend a big chunk of the day fabricating heel board ends and carefully cutting out the old ones but with it being such a safety critical area, i couldn't just leave it so it had to be done.

 

But before that, I began cutting out the other arch tub.

 

I cleaned back the sealer and marked out the spot welds before cutting it out. Ill do it in pictures as it is the same process as the other side which i  have already been through earlier in the thread.

Next I removed the fillet piece that goes between the heelboard and boot floor

 

IhBkI4P.jpg

 

And here is the problem heelboard end

 

XjqtDhx.jpg

 

As you can see, there is a hole towards the bottom which was first thought to be flaky mud on the surface but with a scrape and a tap with a ball pein, it collapsed inwards. 

The crusty area beside the subframe mount bolt holes is paper thin and has gone through in places so it had to go.

 

Here it is cut out

 

TJb7mbC.jpg

 

i have left the captive nut plate in place as it is still welded to the inner sill which will allow it to hold its position while i replace the outer skin. Obviously, the subframe will be trial fitted before being fully welded

 

And here is a close up of what has been going on inside the sill section. Lots of layers of crusty metal were found as well as remnants of old sill which hadn't been cleared out prior to fitting the sill last time they were done.

So i got cracking with a replacement heelboard end.

It starts in the usual way of tracing out the shape onto 1.2mm steel

 

VaPnl1X.jpg

 

Then cutting out and bending the edges over to create the ends.

 

GlpexDY.jpg

 

The O/S one has a new captive nut assembly as the old one was beyond saving and the N/S one is the outer skin only and is shorter as less will be needed on that side.

 

The N/S one will be going in first so i trial fitted it prior to drilling for plug welding

And then clamping back into place on the car.

 

XTyD3tX.jpg

 

x2uZToi.jpg

 

You can see in the first of the last two photos that i have not cleared out the sill cavity prior to clamping on the new heelboard end. There is no need as the inner and outer sills are coming off anyway.

 

The next job was to tack weld the piece into place. It was important to only tack in minimal places to allow for any adjustment of the panel when the subframe is offered up

 

T8dyVnY.jpg

 

It will most likely be fine as it is but i really would like to try in the frame to check alignment before committing to welding it up fully.

 

The captive nut set has movement but it is springy movement so although it moves from side to side, it always self returns to it's natural position which is where i have left it.

Tomorrow morning will see frame being offered up to check heelboard alignment and to mark out the rear mount holes.

 

Thanks for reading

 

Ben

Cheers Jordie.

I don't know why that is. I can see them fine.

 

Can anyone else not see them?

 

Cheers

They take a while to load, especially on a mobile device - maybe the file size is big and the browser is resizing them to fit the screen?

 

Edit - just opened one up and they are pretty huge at full size!

I had that problem, but only due to the quality of my internet here in Denmark. If you see a small square on the left of the thread with a serial number type thing, then right click on it and click show picture and they will show. You will have to do them individually tho.

I started the day by stripping out the old subframe to loose some of the weight from it to enable me to easily lift it into position to check the heelboard position before welding.

 

The using a block of wood and a transmission jack, i raised it up under the car

 

G51Ybli.jpg

 

And good news! The trunnions lined up perfectly with all mounting points so no need for any adjustment :-)

 

e5WEk2A.jpg

 

Whilst the subframe was on, i took the opportunity to mark the rear trunnion positions so i can drill new mounting holes in the new section of boot floor.

Then i took the subframe away and welded up the new heelboard end

 

3Ykopzm.jpg

 

And then ground it all up

 

CCT9IBA.jpg

 

With that done, i drilled the holes for the rear trunnions and then lifted the frame back in to enable me to position the arch tub to boot floor stiffeners.

 

With it all bolted up, things were looking good

 

i18KkCP.jpg

 

So i welded in the O/S stiffener. This is a new one as the old one was not worth repairing

The other side will be done once the inner arch is fitted.

 

A random shot of the new frame

and the new radius arms which are going to be painted due to surface rust.

Next up was to prepare and weld in the new arch tub.

Same process as the other side so again, ill show you in pictures

The back end is nearing completion now so after the valance has been fitted, i will get on with the sills
