Dont the SIP long studs just screw in once the original studs have been removed ?

Daggers might be making a brand new hub. I have done this before.

Would that not be a case of re-inventing the wheel ? ;-)

They would have done, had the previous occupiers of the holes not been force fitted and e-metaled in.

I have sought out a tap now. As 'Knowledge' says 10mm x 1mm pitch. £20 freaking quid. ( i may consider renting it out) :lol:

If I can't find my tap, I might be taping you up (gettit?) to borrow it, as I will need to tap mine in a few days time.

Storkfoot, don't forget your coat on the way out. :roll:
