If you mean making the lip...a shrinker would do it. First one I did I just cut and welded up...shrinker would be neater.
I made one of those forks
I did it by a combination of tucking/shrinking and cutting/welding - as I still haven't mastered tucking/shrinking.
Thanks for the advice. Today was just a quick prod about to see what was there. Just to the left it’s had a hideous patch stuck on top of the sill. I’ll cut that out aswell. I have a feeling I’m going to find a lot of filler.There are three layers at that point. All three will require repair.
- The outer layer is part of the rear wing, finishing in the vertical join line under the rear of the door. The crease or join line appears to have been filled with body filler in your photograph.
- The next layer is part of the outer sill. It is slightly recessed and passes under the rear wing
- The final innermost layer is the vertical closer of the inner wing and a stiffener triangle thing.
You will need to cut the outer wing well above the level you have cleaned and probably to just below the line of the stone chip to get back to sound metal and gain access to the other two layers. Then drill out the spot welds along the wheel arch, inside the door aperture, along the vertical join line under all the filler and finally the bottom flange to peel it away.
A repair panel for that part of outer wing is readily available. If you plan to patch rather than replace the sill you will need to fabricate a repair panel, but as it is not visible that's not too difficult a hammer form compound curve job.
The vertical part of the inner wing is pretty much a simple single curve repair patch from memory, but with a curved flange at the bottom. Again not too difficult to bash out a repair.
Any of the UK MX-5 forums will have extensive guides to the process.
Previous post here as well.
If you get totally stuck we have some photos somewhere of doing this on an NA and NB - which seemed exactly the same BiW to us.
When you have done fill the sill with cavity wax from inside the hood stowage area.

Now I’ve looked at it a bit closer I see what you mean by the outer is wing covering the outer sill. I see the spot welds underneath the wing but surely I shouldn’t be able to just peel the bottom of it up? Should it not be welded to the vertical lip?There are three layers at that point.
