Have you tried the couple of guys who run adverts in ME, not used them but they offer one off part sto completing engines. There was also one in the classifieds not long ago.

Ideally find someone local as these sorts of things really need fitting to the rest of the engine and certainly their mating part rather than just making to drawing.

Hi Derek,

I can recommend John Dunn Engineering, he advertises in the Model Engineer magazine.

Best regards,

Steve.

> Oh yeah I agree mate, and I know it's alot of effort to set the machines up. But £180 to machine me a brass bushing and £280 to add a slot to a gear!

I'd translate that as = "I really don't want to do this job"

You'll find some companies don't want to take 'fiddling little jobs', possibly if in the past such a job has 'bitten' them when the customers expectations don't match their approach – unhappy for both parties. Hopefully some of the suggestions above will find someone who actually wants to do it, and make sure you specify tolerances etc. for any fits – or at least the parts it has to mate to, a bore and key to an exact British Standard are no good to you if it slops on your shaft, or won't go on!

Hi Derek .There is a company near Tintagel that does CNC work ,good enough for F1 racing. I have asked him if he could help ."Only if there is a CAD print and drawing " Email at htp://www.longshores.co.uk The best I can do and hope this helps Maurice.

Why does it have to be cnc?

Can't anyone local to Derek help out with something like this?

Exactly Lofty cnc is the wrong way to go being too expensive for small batch (100) and one offs, they just cant compete. Can be 8 times dearer.

Post some sizes up bet theres plenty on here that could undertake.
