Thanks for the postings. Just to be clear I now have a couple of options of parting blade - the original 5/32" blade and the smaller 3/32" blade...
...but until I read your posts I hadn't put two-and-two together and realized that by grinding the cutting edge in the way I had I'd made the cut narrower than the bottom of the blade - doooh!
I will see what the damage is with a micrometer when I get chance.
My feeling is that the square shoulders of the notch are actually pretty sharp in practice and will result in a neutral rake angle cut good for a thou or two? After all I was able to part well past the hollow behind the cutting edge last night when parting 40mm stock without any noticeable binding problems but I guess time will tell.
