Very helpful stuff, I'll be in touch about valve springs soon no doubt! Any chance of some pictures of the modified pressure regulator?

No after modification you don't see the difference.

Main thing to know is that you have to make the spring stiffer so lets your engineering skills do the work... ;-)
I used a small allen key "headless" bolt M8x10 (don't know how they are called in English, it's all treated a little point at one side and the internal hexagon on the other, used in mechanics/agriculture) and in the lathe made the point look like the drilled out part. (only a few millimeters shorter since that is also the "ball stopper")

I think I understand, I'll have a poke at my spare head and see how it goes.
