well was watching a video on wood turning and noticed this guy roughing gouge had swept back wings, like a bowl gouge for example.
just wondering if this is a common thing or a specialty thing??
or has anyone done this?

Mat, have you got a link to this vid.
I relieve the corners off my SRG, but the profile for 95% is straight line.
im trying to find it again but it looked like a roughing gouge with an Ellsworth grind
I think two of our members of the wood turning group has something similar to what you have described. I should have asked to borrow it when I had the chance as the ones that I have are all square to the turning. The wings for mine are very slightly rounded to prevent catches at least that's the theory.
It depends on what you use 'em for.
I have a smallish 1" RG that I use primarily for roughing blanks into cylinders. I leave that square across to reduce the number of trips to the grinder... I simply roll it to present a "fresh" edge until the whole edge needs a touch up.
I also have a larger (40mm OD?) one that I grind with swept back wings. Almost a large fingernailed detail gouge profile, but I wouldn't call it an ellsworth. :no: This is because I use it to rough curved, concave sweeps into some forms and the... lack(?) ...of wings means I can safely achieve a tighter curve. Increased versatility there means more trips to the grinder though. :shrug:

If you Google a Utube by Todd Hartzell doing a demo for WGNC ,you will see a demo of a roughing gouge sharpened like this.About 16 minutes in.
I don't know how to do the link, but maybe someone else can do it.

Here are some examples, Kelton 19mm Bowl Gouge, P & N 22mm Supa Gouge and P & N 32mm SRG.
The Kelton and Supa Gouges are used for roughing bowl "blanks", usually pieces of log split in half and edges knocked off with a chainsaw.
Ted, is this the one?

Its a "continental roughing gouge" with a typical grind. Popular in Europe & turners like Eli Avisera market their own versions. Hartzell's has a deeper flute than most.
Yes Pat .Thats the one.
Ted
yes it was something like that but a normal U shaped roughing gouge
Hmm. I'm not going to watch an hour of video to find the bit with the roughing gouge.
Anyway. Roughing with a bowel gouge works pretty well. Works on softer woods better. and maybe smaller dimensions. But you sort of have the handle leading. :think: pretty hard to explain. ..... to get the whole of the wing working. I guess it will require another video to explain.
Hmm. Found it. At the 16 ish minute mark. Roughing gouge with swept back wings. I'm not sure he was using it the best way. ....
I do mostly bowls, with a few weed pots and tool handles. I don't as yet have a roughing gouge. I use a 5/8 inch bowl gouge with a slightly swept back grind or a heavy 5/8 inch scraper for roughing spindles.
About half of my spindle blanks are quartered logs. The above seems to knock off the corners quickly enough.
