Getting the correct angle

[Celt40]

This might be a strange question to ask? It is something that gives me trouble every time i go to sharpen my tools.

What is the best way to set the required angle on a jig platform table???? You will think this a silly question, but i find when using angles my brain will not grasp this simple task!!!!
If i need to sharpen say a roughing out gouge and i needed to find an angle of 45 how will i find this?.[:I][)]

Dermot, this sketch show how to set and angle. This one shows 7deg but just change it for the angle you want. If you have a line coming from the centre of the wheel extending outwards, you simply set the angle to this line as it goes past the edge of the wheel. The drawing shows that you can have the line anywhere. If you want 45deg, then you would want the line quite high on the wheel.

Thanks skiprat I felt realy stupid asking this question, but with angles involved my brain shuts down.

Iam having a real battle with my bowl gouge, getting the correct angle. I think that my problem is that i have turned back the wings too much. This has given me a pointed tip, instead of a finger nail look. I have lost the angle that i had ( and a lot of steel ) i will need to get it back to about angle of 55???????[)]

I have a wolverine jig so i don't know how i have went so far of course. These jigs are ment to be idiot proof, quess i must be idiot +.

I use a black marker and color in the grind area of the tool. Then, when I think I have the rest set correctly I place the tool against the wheel and spin the wheel a little by hand. If it is set correctly it will show a silver line the length of the grind. If it doesn't show all the way from top to bottom I readjust the rest until it does.

Hope that makes sense.

They are not idiot proof, there is just a learning curve like everything else we do. As you've found, the wings grind down faster than the nose, so next time you grind, focus most of your time on the nose area. Hit the wings first, get them in shape, then avoid going back to them unless necessary to smooth out the curve. The majority of the time will be spent on the nose due to the slower pace of grinding that area. Have you checked out the videos of the system at the Oneway site? You may find them helpful.

You'll get there, just takes practice. Perhaps you'll want to pick up a cheap gouge to practice with if your main tools are pricey ones.

Hope this helps!
