Spindle Roughing Gouge Grind Shape

[Doug Freeman]

Honing a hollow grind - hone for a small microbevel, thats it.

Skew honing - 600gr on each side till I see a small microbevel, then strop the burr, usually strop both sides some

SRG - I do use them “as a skew”. I have a ceramic hone for the flute to turn the burr, then a quick 600gr hone for a continuous microbevel.

Gouges - hone the ID with ceramic hone if taken to the bench grinder to turn the large burr, then sharpen on wet wheel smoothed to 1000gr, no honing after.

Scraper - sharpen on 80gr stone wheel. May use as is. For a finer cut, stronger burr, or to refresh edge, turn burr down with carbide burnisher, hone 600gr, turn new burr with burnisher. After a few hones the microbevel grows, back to grinder.

The terms 'hone' and 'strop' are used interchangeably. To me, they are two different things. To me, honing is using a very fine diamond card, or very fine grinding wheel to refresh an edge. Stropping is a compound on leather or canvas, and the purpose of it is to remove the grinding burr. Honing creates a burr, and I have used stones up to 15000 grit, and even with a very light touch, you still need to strop that burr off. I keep my SRGs at 40 degrees. I like the way they cut at that angle. For roughing out a big log, like over 6 inches, trimming down some big spots might help you some. Check out some of the You Tube videos where they turn down 20+ inch diameter logs into large vase shapes. They are using a scraper. Some times I want peeling cuts (basically cutting on a tangent to the spindle), some times I use just the wing of the SRG, some times I whittle down the end of the log section with the SRG at a 45 degree angle, kind of like hand sharpening a pencil. Some times I like the standard SRG, some times I like the old bodger's tool the continental style SRG. I am one who has to experiment a lot..... I never strop the SRG. I always strop my skew chisels. I never strop my bowl gouges. Most of the time I sharpen them on 180 grit CBN wheels, some times 600 grit. That keener edge comes in handy with punky type woods that tear out no matter what you do. Scrapers, 180 grit wheel as well, and about a 70 degree bevel. I do keep a number of shear scrapers, sharpened on 180 grit wheels, and I will burnish the burr down and up a couple of times before going back to the grinder. With the M42 and V10, a carbide scraper works a lot better than the standard burnishing tools used for card scrapers.
