Ok, can someone please confirm to me that I have been a total prat..
If I hold the 1pc crank, with its NON driveside arm towards me, (facing down), the bearing race screws on counterclockwise. Therefore, it screws off clockwise.
From this, I deduced that the nut holding on the chainring, given that it cannot (from the look of it) come off the crank over the slightly fatter shoulder of the drive side, must logically come off on the non drive side. For it to to do so, I assumed the thread must mean it too must screw ON the same way as the non drive side, and therefore unscrew clockwise.
So after 20 mins banking it with a hammer and screwdriver, I managed to move the chainring nut about 5mm, and that took me 20 mins.
So have I actually just tightened it to buggery, and failed to see something terribly elementary, and should the drive side nit holding the chainring actually remove itself counterclockwise, defeating my logic?
Or should I just piss off down the bike shop and hand it over to some nice people who arn't idiots?

pretty sure the nut holding on the chainring is a right hand thread dude, like a regular nut...
it's only the non-drive side bearing cone nut and locknut which are a left hand thread.

So, to use northern terminology you think I've been a right fookin twat, and simply spent 20 mins tightening up all already bloody tight nut?
/scream
I just assumed I'd not been putting enough effort into the hammer!
BrianP:
i think so bud, sorry. but if it makes you feel any better, i broke a spanner trying to remove the non drive side pedal on my first bmx before realising it was a left hand thread...
