Revisiting a grinder question

rprevett

>'Newbie' asked some sharpening/grinder questions yesterday, and one of them struck home. Unfortunately, that one did not get addressed, so I'll re-ask it:

'I bougth one of those diamond impregnated block on a stick things. It knocked the eccentricty out of the wheel alright, but left some pretty deep tracks in the wheels. Problem or not?'

Seems to be a problem for me. My gouge wants to fall into those tracks as I roll the tool in my jig (wolverine).

Do we use the dressing tool to grind those tracks away. How, without forming new ones?

TIA,

rick

>Rick: You are supposed to move the dresser from side to side as you press it against the wheel.

>Even though the block head is wider that your wheel, do Not hold the block in 1 place. Move it carefully side-to-side, using your finger against the outer edge of the tool rest as a jig and gentle pressure, across the face of the wheel like you're "sanding" the surface. Your stone will come out smooth, even and square.

>Mark,

I'm having a real problem moving it side to side AND keeping to square. The instant I move it, it wants to pivot on the edge of the wheel....

>Sounds like you are a) trying to do this freehand, b) pressing hard, c) both.

Set your tool rest, a flat plate style, such that you can hold the "block" and handle on the rest and then just slide the "T" side-to-side on the rest with the diamond surface just barely touching the wheel.

If you're allowing the diamond surface to round the edge of the wheel, you must be pushing much too hard. Just a light touch to keep the diamond chips in contact with the wheel is all you need.

If you're not using a tool rest that is steady, very close to the spinning wheel, and supportive of the dresser, you'll not be able to control the cut.

Hope this helps

>If you have a patten or flat plate for your grinder you should be able to dress with the plate very near the wheel and just slide it across the wheel in a smooth stroke. If you are like me and have taken that off for a jig and no longer know where the thing is, then just rest the dressing stick on the shrowd of the wheel and just litely touch up the wheel as needed. You can also make some kind of stand on which you can slide the stick across the wheel in an even manner as well. I usually take one pass from both sides of the wheel to try and keep it even.
