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

One other question, when turning logs should you remove the bark first
or turn it off

TIA

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.

[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. Boy times going
sowly

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.

Just noticed your post, but that seems a lot to pay for that grinder:
Axm,inster do it for a lot less, as do Wickes


I agree after a lot of looking around i found the axminster the best
price and also the only one at that price with the white alli wheel on
the high speed grind wheel. Should be recieving it on monday
