Back to the drawing board I think!
Lots of work getting a setup spot on - lots of work getting a setup functional more to the point here!.... I wish I was going for spot on at the moment!
On this subject - the rings for my 8" dont have mounting gear on top, ie just a smooth belt of metal (Aluminium I believe).
Should I try and attach something to these, or just get some rings with a mounting bracket integral?
