If the BSA has dovetailed lumps welding the hook is not a good option. Welding across a solder or braze joint will bring no joy!
Huh? There are literally thousands of dovetail lumped guns that have been rejointed by welding the hook. I've never seen an example that had the lumps come loose either. I've also seen chopper lump barrels that have had their hooks welded. Or...are you talking about barrels put together like a model 21? The BSA design is actually a combo of both. 99% of Damascus barrels are dovetail lump construction.
Maybe just too over generalized of a term and it caught my attention.
