right

got a waterblock that had a badly tapped hole, its got some slight damage to it in places (looks worn down) and i need to get a barb into it (don't care if it never come out again)

the one that was in there was stuck half way so i removed it with a vice, anyone here willing to have a go at fixing it for me?

i'll pay postage both ways of course and happy to send a fiver along with it for fixing it

sorry for bad pictures, my sony's flat and dunno how to use my mum's canon properly :p
 
What is the waterblock for and what is it made out of (aluminium I suppose).
Do you know what thread it is?
 
Does it have to be the same size, or is it possible to make it a bigger thread size and use a correspondingly bigger bolt (or whatever you thread into there)

Retaping a hole out to the same size can be problematic, sometimes you just can't do it, sometimes you can but the thread depth is shallow, etc with thin metal sometimes you can apply pressure to 'flatten' it a little to close the hole a bit to counteract that, but I don't think anything like that would be possible on your block

EDIT: I don't think I could do it for you, I don't know what size it is, but it looks quite big ... 10mm ? and I don't think we have any taps that big + as VIRRI says there are different threads, etc so its not just the diameter, its the series of threads it belongs to as well

i know how to do it, and am pretty good at it (did it solidly for a week on a job one summer) but i dont have any kit to do it!

if you give us the dimensions i'm sure we'll be able to advise you on how to do it, if anyone has the kit from here i'm sure they'll be able to do it easily.

the change in size might affect the waterflow though.
 
depends how much pressure the thread has to take? there is a process called heli coiling which puts a new thread in and most decent motor cycle shops should be able to do but it isnt quite as strong as a normal thread
