Hi guys,
The spanner I was sent has slowly wore away and now it just spins round the shaft rather than grip into the indent.
I'm not 100% sure where to purchase another one from.. when I search for ER11 spanner etc. I just get links to the larger spanner for the actual nut. I'm looking for the other one, to stop the spindle spinning as I try and tighten the nut.
Any ideas? I've tried a 13mm spanner here but it's too small.. and my 14mm is too loose.


Many thanks for any help!
