solid gouge = skewchigouge ?
Bob,
A while back there was a discussion here or on WC about taking some 3/8" round bar and grinding down the end by leaning it against the grinder, removing about 3/8 of the stock on the end. Orient the ground part as up, put it in your Wolverine, and put a spindle gouge grind on the remaining portion. Doug Thompson sent me a piece of his steel that he had ground this way and I put it in a handle with a collet. You can get a smooth cut with this tool like you wouldn't believe. In many ways it behaves like a skew, but cutting downhill on a spindle you get a surface that is burnished and smooth. This is one of my "go to" tools.
There was a tool called "skewchigouge" I think that is similar to this. It may still exist. But this is what I think of when someone says solid gouge. I checked and it is made by Crown Tools and was developed by a Brit named Alan Beecham.
I'll try to take a picture of this tool.
