Hi, Does anyone in the Sheffield / Rotherham / Chesterfield area have an M18 x 1.5 tap I could borrow?

I just welded the lambda bosses into my headers, and the thread in one has distorted. Not looking to take it away, I can just bring the headers run a tap down them, and buy you a beer.....

Cheers.

Pete.

I would have thought Martin Keenan should be able to help if nobody else local, but I have a tap in Thornhill you can borrow if you want a run up the M1 (currently in my drawer at work but will be home as of tomorrow afternoon)

...or make your own thread cleaner out of an old spark plug? Snap the porcelain off and cut a couple of grooves down the length of the thread with a hacksaw. Just don't use to much force and snap it off in the hole!!

Thanks guys, I found a cheapie on ebay for a fiver, which I hope will do the job before it fails....
