Hello List John M Ross said: "install them like a French butt spring" This is the common way of installing Butt Springs in the UK. It's known as "sewing" them in - and it's VERY fast. Another method in use here is to use the very same springs but they are kept in place by a small dowell or some "action string" - there being a hole drilled right through the butt spring slot from one side of the Butt (Block) to the other just for that purpose. I prefer sewing them in though. Regards from Sunny Sussex-on-Sea Michael (G)
