@Richard.Dane - just trying to clarify this one line in your guide:
“Tighten to the point of resistance then tighten about 1/8th of a turn further until you fear that the spanner will begin to deform.”
Are you saying that one should tighten until one fears the spanned will begin to reform - but no more than 1/8th of a turn max from the point of resistance?
Or continue tightening, 1/8th of a turn at a time until it’s super duper tight and one runs the risk of deforming the spanner?
Any spanner - or just the one provided ?
Also point of resistance - is that while one is finger tightening it?
Or is the point of resistance while one is using the spanner - so quite tight already - and then some more - the last 1/8th of an inch…
Thanks!
