So here it is all finished, about 8 hours work including grinding and sharpening the blade.
I've ordered some proper countersunk brass bolts to replace my home made efforts, but apart from that it turned out very well.
It is 6" long x 2" wide and 2" high with a 1 1/2" blade, bedded at 55 degrees.
I polished up the lever cap and screw head but I think a brushed finish may have been better.
The wood grain looks nice, especially with no glue line for the sides.
