I have seen Ken’s stainless HW design guns and have always fancied building myself a stainless steel HW80 style rifle with some improvements.

The 80 is a nice starting point as most improvements have been tried and the good known mods can be designed in at the start, the trigger unit can be probably the only borrowed bit from a production gun with the rest including the stock and checkering being an interesting engineering exercise for the winter evenings?

Has anyone ever done something like this other than this chap in the states?
