I never claimed to be a cheap date 

Seriously though, the overhead is huge for a CNC mill, Software and yearly maintenance, tooling etc. Well north of 40K so far and I am thinking about upgrading to an enclosed mill. The story of a repair costing more than a gun is worth is not unique to this project. Surely you see similar situations regularly in the UK. I currently have over 40 hours in this project, though much of that was learning the new software. I think you could have a workable new hammer in need of fit and finish in about 12 hours with some practice.
