Thanks for the good wishes guys. I am a car mechanic to trade (for 20 years) before moving to trains 7 years ago so thought I'd seen the last of wee shitey studs that break easily.
I had an evil thought earlier when I saw the option of drilling new stud holes, & thankfully someone else has tried it with success, so I'm defo going to try that after I buy a new set of quality drill bits (Screwfix, here I come).
I'm in no rush due to weather & old age so it will be a bit of time before you see any good pics. I will, though, keep you all updated with any progress that I make & any further cuts & lacerations I make to my fingers & hands.
Great site guys, keep in touch.
