Oh sure, blame poor old me
Make the tool, it is not a bowl gouge, but like Jeff says, what have you got to lose?
Making a bowl gouge, heck I've already done that!
My steel was not hard enough, and it did not work out so well, but I figure I could make a good bowl gouge or two, if I can find a cheap source of M2 HSS.
This is my idea, steal it if you will
I have a SCMS, it slides out more than enough to cut a flute on a gouge. On my saw, I can set the depth of cut, so the blade will just cut through the table top, or cut deeper etc.
OK get an abrasive blade that fits your SCMS, and then make a jig that holds the piece of HSS you want to make a gouge from. Everything would have to be clamped down really tight, and you would take fairly light cuts, but I figure it is totally doable.
You would have to shift the jig left and right a bit to get a wide enough flute in a thicker piece of HSS, but I also do not think this would be a big problem.
There, the solution
Now you REALLY can blame me
