Thread: Dressing Grinding Wheels - Diamond point or T-dresser?

I haven't used the T dresser but I imagine it would be a case of hold it against wheel and it does the full width of wheel in one go, it may give you a flatter wheel face when compared to a single point dresser, a single point can also give you a flat face but a steady hand is needed if dressing freehand or some sort of jig is needed to traverse the face of the wheel to get a flat face if the hand is not so steady, a single point can be used to shape your wheel if so desired.

To use, just approach the wheel face with care and a softly softly touch, no need to be heavy handed, don't let is dig in as it will remove a lot of wheel quickly especially if it has a soft bond, a couple of passes across the wheel face should be all you need to remove any blunt grit.

The wheel type can be effective but slower than a diamond tipped dresser and need a little more force when using, mine has legs that I can hook over the work rest to get some leverage, adjustment of the rest is needed before and after dressing tho if you use the legs, what I usually do is use it with the legs up

Thanks for the reply Pete. The T-dressers are only about $7 on eBay, so I'll get one of those and see how it goes.
I'll also buy a point type, then I can try both. They're only $25 at Carbatec. I read somewhere that a T type is good for cleaning/dressing a wheel, but that the single diamond point type is better for truing. Dunno if that's true or not.

Your mention of a jig for the single point types was part of the reason I posted. I couldn't imagine doing a very good job freehand, personally.
I'll buy a Carbatec grinding jig/tool rest. It has a mitre slot running across it, so it won't be too hard to set up a specialised dressing jig. I'm guessing a setup with a micro-adjuster would be best, from what I've seen on YouTube.

I'll give the wheel type a miss initially, and see how the others go.

Given my choice I'd buy a CBN wheel anyway. Hopefully sometime not too far in the future.
