Hi.
I bought some second hand Agir Brokk twinning bands for my MDE manifolded Faber twin 12s. They are the correct (B) size for them but just won't seem to tighten up correctly.
The bottom bands tighten up fine but the top ones leave a slight gap between band and cylinder.
I have swapped the bands around and get the same result on the top

Am I doing something wrong or are my cylinders conical!?
Cheers,
Darren
