There is also Hamlins of Bridgewater that would be a bit closer for you. I have not used them myself but have heard they are good. The chap I would have recommended, Gary Bowden of Patchway Bristol, has retired so I also need to look for a new company when I next need a job done.

Thanks for that, funnily enough Gary Bowden did the previous work on my engine but as you say he has retired now.
There is another guy Steve Riley of PISTONBROKE down in Bristol who I've heard is very good but I will consider Hamlins too .
Thank you all for your help and advice. I think I will search around for another crank that's had less regrinds than mine.
Failing that I will use my own for one last time. I understand what you both mean about taking the minimum off the main journal and bore the bush to suit.
One final point - I know someone that has had dealings in building up material on industrial pump shafts.
I need to find out more but I think there is a process of spraying on metal so it can be ground back to the original size.
Has anyone had experience of this? How strong is the material?
Maybe I could get my crank journals built up and go back to standard size!!
Any comments on this would be appreciated.
