Helicoil for sure!!!
I stripped a brae mount in my t-rex, and i was gutted, so i asked about and helicoils where the obvious choice.
It is VERY easy to do! all you need:
Cordless/corded drill
Tap holder
And the helicoil kit(providing this comes with the 5.2mm drill bit and the tap.
The drill the mount out with the 5.2mm drill bit, put the tap into the tap holder, thread the mount, then get the heliciol driver and spin the helicoil down the newly placed thread, Then get the tang remover, put it on the tang, and hit the end as hard as possible, turn the frame upside down so all drill shavings and the tang fall out. and thats it (N)
Easy Peasy, my helicoil kit cost just under 15 quid and came with the 10 helicoil insters, the helicoil driver and the tang remover, but the 5.2mm drill bits where only 10p (N)
Any more questions pm me or add me to msn if your really needing more info.
