Help with sharpening

[dahlia1]

Hi,
 I have the Axminster sharpening jig, when sharpening I
Colour the bevel, when sharpening a bowl
Gouge and also a spindle gouge I seem
To miss a small area on the wings
I have attached a picture, my question is does it
Matter, if yes how should I ammended
My grind to cover those areas

Which jig and what machine, grinder, pro sharp etc? It is usually the set up of the jig which affects the bevel angle and wing shape

I have the Axminster woodturner sharpening
System(£120). Used with a record rsbg6 grinder
This has a 20mm grit stone and a 40mm white
Stone. I have been using the 20mm stone
Would I gather better results using the wider white stone

[Lazurus]

I use a Creusen grinder with 40mm wheels and find it great combined with the Sorby jig - yours is similar to the wolverine type, the instructions on line look very comprehensive so follow the to the tee initially and yes try the 40mm wheel its just a case of fettling until you get it set up to suit you.

YES use the 40mm White stone it is quite good, NEVER use the 20mm grit stone unless you have nothing better.

The picture is not sharp enough to be 100% certain, but having ink left on those wing tops means that you have probably over rotated them at some point creating a second bevel, which is very easy to do with the course grit of a standard grinding wheel.

Basically that wing is your main cutting edge, if you can see it, it isn't sharp! Switch to the white stone, take note of the start stop position of the handle swing and work your edge back until it is completely clean and see how it cuts! Then try to repeat that on every sharpening.
