Adapting spare parts tip
Had an idea today, but someone may have done this before. Just re-blued an old BSA but lost a locking screw. After hunting around found a replacement (think it could be 7BA), but the head diameter was 1mm too small 3.8 instead of 4.8mm and the head was also far too thick. Thought what shall I do, I know, squash it flat.Drilled a 2.5mm hole in a piece of flat bar so thread is protected, put it in a vice and squashed the head to 4.8mm diam and it also ended up the right thickness. Some of you experts may have noticed the screw was missing on my earlier thread.
