I did it like this:



Following the advice in this recent thread:

http://forum.triumphdolomite.com/viewto ... 1619a8502f

Like you, I did not want to disturb the top seam, where all was solid. I cut the club reinforcer along the top - there is a crease where it would fit into the top seam - so that it fitted up behind what was left of the old reinforcer and against the inside of the top of the sill.

Hope this helps.

Yes. the lower edge of the reinforcer is turned at right angles, inwards. That sits on top of the inner sill repair panel (this is really just the bottom of the original inner sill, the bit that sits parallel to the road surface) and the inner sill repair panel itself has a right angle turn downwards at its outside edge. The outer sill fixes to this downturn along its bottom edge.

I just welded along the seam that you can see in my pic, and then ground that weld back with a flapdisc so that it was flush and did not impede the outer sill fixing.

Is that what you were asking?

This is what most people do! When I did the sills on the Carledo, I actually found the diaphragm panels intact, must be a record! I used a length of 1"x1" L section steel to make a joining panel the full length so I had 3 thicknesses of steel at the bottom sill joint to the soffit.
But it is technically possible, if you are lucky and clever, to drill the sill along the line where the diaphragm meets it, fit the sill and then plug weld through to the bottom of the diaphragm, mimicking the original design. Plug welds here would be acceptable to MOT standard since the original join was spot welded. Take your pick! only one choice per customer!

My door posts are in good shape. Just one small hole in the O/S D post, where the sill meets the wheel arch, fixed with a small patch.

I have also had to replace both chassis legs (gearbox sides). Also a new O/S front floorpan which had rusted though. I could have got away without replacing the N/S floorpan but it was a lot easier just to cut it out with the chassis leg and the club repair panels slot in nicely without too much fettling, so I am replacing that one too.

For the jacking points I saw that someone on here had welded short (approx. 1cm?) lengths of box section pipe to the under sill to provide a location point. Seems like a good arrangement which I may well copy.

I think my chassis legs by gearbox,also need attention there bend and buckled,ive spot welded the lower section of the middle sill,mig welder went wrong so couldnt finish next job to takle is jacking points,starting with a middle jacking point

That should take any amount of stick dished out by Thicktwit fitters!

Thats what im going to do,found some 3 x 3 box section in work shop,i know its a bit of over kill but its free
