Easy enough to cut a small square in the outer cill back to sound metal, insert a small repair piece and tack /braize in place and then fill and paint. £100.00 should cover it.
of course if the rot is extensive and structural thats a different matter.
Nice job Morris........I especially like the Tescos cornflake packet template! I reckon you must have cut your teeth on MG's

Thanks, Peanut, not MG's but Morris Minors. I have restored two now.
I would not tack/braze the repair piece in place as the sills are part of the car structure, so fully seam welded is the way forward. The idea is to re-build the cars strucure to as close as original, restore the strength to the car and make it look original but at less cost than full sill replacement. So if a full sill is not needed then high quality local repairs - just the rust cut, make new pieces up and butt weld these in. I cut those holes back to clean metal, the paint was intact inside the sill where I had cut the hole. I also cleaned off any rust from the inside of the sill. The rest of the sills were in good condition. (apart from a patch of "surface" rust at the front- more on this in another post).
I agree though, definitely go to a good classic car restorer not a local garage that does MOT patches. (Unless their work is high quality).
Incidentally, the templates were made from a Tesco fruit and fibre packet, although I now prefer Sainsburys now as it gives a more accurate repair section[

Yes, the repair should cost hundreds and not thousands and unless the sills are rusted out all along then a local repair is perfectly acceptable, as Barry Hart was quoted in an above post. We can save the lower value cars too!
