Thanks Chippy. To be clear, what I meant was not that experience are necessarily stuck in their ways, but that some can be, and because I'm new that's not a possibility.
No, I don't don't use the ruler trick either, although I have once or twice in the last year or so.
I would have expected someone such as yourself to have a couple of different methods, depending on on workshop or site work.
Cheers

profiling the grinder's wheel to a radius helps to control the process. the profile means that only part of the wheel is in contact with the blade, reducing the amount of steel in contact with the blade and hence the risk of overheating. Derek has written here or on his site about it.

Well I did what FenceFurniture did and got me some diamond paste and had a go on some chisels then on my new Veritas router plane blades straight out of the box.
All I can say is that FenceFurniture is the new god of diamond sharpening. I ordered 8000 and 14000 paste and had a go tonight on MDF. I was impressed, the chisels are BAFB (beyond all FXXXing belief) scary sharp and I got a mirror shine. I then had a go at the Veritas router plane blades. After working on the backs with waterstones starting at 400 then moving through 1000 then up to 4000, I went for the 8000 diamond paste. Well did I get a nice surprise so on with the 14000 paste. I'm hooked for life and so easy with little mess. If I can find out what to replace my 400 to 4000 waterstones with diamond plates or paste I'll be a happy man.
Sorry, I know this will upset someone with a different method but this is the way I'm going.

G'day SB, I'm really chuffed that you got a benefit out of all this. Seeing the first one come up to mirror is a revelation (of ease) isn't it? More than anything it's the lack of mess and the quick setup/down that has me hooked.
Gemcuts have the paste in
100
280
325
600
1200
1800
3000
8000
14000
50000
100000
and they're all the same price.
I will get a 600 I think, to go after the 600 DMT plate (I suspect they are not identical).

That's interesting. I was re-reading your post again. One of the problems of profiling a grinding wheel is that immediately after having adapted it to the specific purpose you need it back for the original standard use.
Of course the answer is to have a wheel that is just interchanged as required. Then I remembered I have about thirty such wheels. I bought them from a sawmill that was closing down. They had used them on the gullets for their bandsaws so the edges are a full round (make that 180 deg).
I also remembered why I hadn't used them. They have a larger diameter hole than my bench grinders and some of the wheels are too large a diameter.
However I might have to borrow Brett's thinking cap, if he hasn't worn it out, and come up with a solution. Oh, and the wheels are probably a little on the coarse side so I would have to stop any grinding in good time. I aim for about 1mm to go normally.

Did you ever watch a child's cartoon programme called Banana Man? Banana man, a superhero, had a mentor in the form of a crow, who typically sat on his shoulder and offered advice. The crow would offer advice and Banana Man would respond with an exaggerated "Ooh Yeees!"
That makes you the crow.

to expand on my earlier commentfrom FineWoodworking
... The key to the grinding technique is a slight curve across the edge of the wheel (see illustration below), as opposed to the flat edge most people think is right. You'll need a wheel dresser to create that curve, and to reshape it when the center wears down.

I have a question for the experts, does diamond paste vary in quality from different suppliers?
