It is.
My Golf's tensioner started sqeaking a bit at 180-something K, no history available, may well have been the original for all I know.
"Shall I change it?" thought I, "Nah, I'll wait 'til the stem seals get a bit worse and do it then."  :)

by the way there was another thing i wanted to discuss

i know this should be easy but i just couldnt do it  :-[ ....... and thats sharpening drill bits. i took a couple of drill bits that the teacher said needed sharpening and the angle should be 59o. sounds easy. nope! it just seemed that the 59o angle was too flat and ended up worse than before.

if im being retarded tell me and ill just keep practising  :-[

anyone else have this issue?

You can either sharpen a drill ..... or you can't. I know some fitters that have socks older than you  ;) & still can't sharpen one.

I can!  ;) ;)

You need to have a go at sharpening a drill of 3/4" and bigger so you can see what you're doing. I've just been Googling but can't find what I want. A morse taper type drill has a centre in the end that helps you keep each side of the drill equal. You can sharpen a drill that only cuts on one side, and the gauge/guide helps.

to give us something to do me and a couple of others are going to be making a gauge for our key rings cos we're so far ahead. its basically just an angled piece of metal (at 59o). this what you mean? or the drill bit itself?  :y

That's what I found on the net. The gauge I meant has a point that you sit the end of the drill on so that you can scribe each side of the drill on to check each side is the same ....... far too difficult to describe, far easier to show you in the metal.  :y :y

There was a guide in a cupboard at work. I asked a few of the lads what it was, nobody knew - even the old barstewards like myself. I'll try to remember to photo it in use. (not back in work till Tuesday though  ;) - assuming Warren B hasn't closed it by then  ???)
