I really can't understand what's going on in this thread at all. Peace
The bottom bracket shell is the part of your frame the bottom bracket screws into
old steel frames often have stripped damaged threads on the inside of the shell which can be recut. In my case the thread on the drive side is worn out so the thread can't be recut as the opening in the shell is too big for the bottom bracket.
The options are for a the opening to be shrunk by adding in metal somehow and then new threads cut in the new metal - best option but pricey - or to have a threadless bottom bracket like the one linked. This is a less secure option but quicker and cheaper and it may work.
