sharpening jig for wet stone grinder
Hi
I have just brought my first lathe ( sealey sm900 ) and i'm now looking into ways to sharpen my turning tools. From reading through the various posts on here about jigs, they all seem to be about standard bench grinders. Has any one got some made for wet stone grinders, self made or commercial. this link is one i'm thinking of buying but most of the cheaper wet stones are of this design http://www.worldofpower.co.uk/acatal..._Grinders.html One other question, when turning logs should you remove the bark first or turn it off TIA Mark |

My jig should work easily for the wet or dry wheel on that grinder. See my web page for how to make it. If the bark on a log is loose, remove it before turning, otherwise it is up to you. Loose bark will fly off the lathe and may hit you while turning. A face shield is a good plan regardless. -- God bless and safe turning Darrell Feltmate Truro, NS Canada www.aroundthewoods.com |

[My jig should work easily for the wet or dry wheel on that grinder.]
Are the angles still the same, as the jig looks good to work with a wet stone grinder. What would the best grit size for the wet wheel if it was optional? Although i have absembled my lathe and quickly spun a piece of soft wood between centers. This is a birthday present from all the family and they have hidden the hss tools until the 25th.

The angles in question for any sharpening jig, whether my home made version or one of the commercial types, are really the angles on the gouge or other tool. All require some experimentation. For example, for a typical bowl gouge with a 45* bevel, you would make a 45* holder, that is the dowel projects at 45*. This does not determine the grind angle. That is determined by the distance the tip protrudes from the holder and the distance that the pivot is from the wheel. Basically you play. Start with the tip protruding about 2" and the pivot back about 7". With the grinder OFF, check the angle that the tool makes with the wheel. Adjust until you get the angle you desire, turn the grinder on and give it a try. When you get the settings you like for tool X, write them down or make stop blocks or whatever. I like an 80 grit wheel. With jigs, 100 is fine. Anything else is hard to feel when sharpening. On my grinder I have an 80 grit aluminum oxide for sharpening and a 36 grit for shaping. Hope it helps. -- God bless and safe turning Darrell Feltmate Truro, NS Canada www.aroundthewoods.com |
