Life is a continual learning experience and I have wasted far more money  :P

I spoke to engineering co suggested in Wallington and they can diamond hone for about £30, but it means getting it to and from them.

I have bought an adjustable reamer from UK so will see how that goes.

You will still have to visit a machine shop as, the seat angle needs to match the new guide  ;)

Luckily I have a Neway carbide valve seat cutter that I bought 40 years ago  :D
