have been in contact by phone. very helpful guy there called simon.
im sending through that diagram. he thinks we'd be looking @ £80 pound for each bell(which would be a one of payment, and 200 per side for discs. good thing is the bell is a one off buy and when it comes to replacing you only need the outer disc.
they can do drilled or grooved(personnaly i dont want grooved)
and even better news they will do group discount. with 5 people he said the bell could drop to around 60-65 quid.
prospecrts look good.
anyone got any other schematic diagrams or other important dimensions for the discs incase the above diagram isnt good enough.
