Question about modifying multi point diamond dressing tool

I am not a regular reader of this group, but have alway been impressed with the sophistication of the members and have a question that I am
posting here.
I am wondering if anyone has had experience creating or modifying multi point diamond dressing tools. Either a source for diamonds and a technique for affixing them to the dresser tip, or maybe suggestions for cutting off a section of a pre existing dressing stick and affixing it to a different dressing stick.
In case it is of interest, my application is that I want to replace the large and inconsistent diamond bits on my Silvey Pro Sharp square chainsaw grinder dressing tools with diamonds more along the line of a Norton CDP 3128-HD dressing stick.
In spite of the $2000 price tag of the Silvey Pro Sharp, the diamonds that come with their dressing sticks are really awful looking- mostly about 3- 4 large bits that create grooves on the wheels. The dressers are mounted to the grinder for precision, so I can't simply use a hand dresser as I would on a normal shop grinder. In other words, I need to come up with a way to upgrade the Silvey dresser tips.
As a woodturner I am into VERY sharp tools (including chainsaw chains) , which require the right wheels and wheel dressing.
Thanks for any suggestions. Bill

Sounds like you need a radius dressing tool to hold a single point diamond dresser. Check Ebay for radius dressing tools, and, if you can, find a place that sharpens ice skates and see if they will let you look at the arrangement of their dresser, as they use a radius for hollow grinding skate blades.

Probably my post was not very clear. I definitely want to replace the diamonds on the grinders dressers with multi diamonds as that gives a more consistent wheel surface. The issue is the size and quality and number of the diamond bits that Silvey puts on the dressers. I know from years of experience that if I can go to a finer and more even pattern it will give me a much better cutter edge when I sharpen.The way a grinding stone is dressed affects how sharp tools end up even more than a step in grit size (say 80 to 100).
This particular grinder utilizes a roughly 90 degree sharp edge it forms into the grinding wheel. It has two multi tip dressers that are held by little swing arms that fairly precisely form and dress each of the wheel "bevels" that meet in the wheel's sharp edge which fits into the inside corner of the square grind chisel chain.
So I really do want multi diamonds and as true and flat the end of the dresseras possible to be the most effective as it rotates and swings through its arc while dressing. In the simpified solution, I would somehow simply "grind" away the old diamonds and reaffix new ones. But I don't know how the diamonds are attached, and always assumed it was some something like an electroplating process.
The new diamonds don't need to be as consistent as graded diamond sharpening stones (DMT etc), but if you could see the old diamonds as compared to my everydayhand held dressing stick for my 8inch Baldors($5 at Boeing Surplus) you could easily see why I am motivated to replace the old diamonds.

It seems to me that you are looking to try to improve an idea that was not so good in the first place.
Multiple diamond dressers work great for cleaning up a shitty bench stone. All the accurate grinding setups I have seen have been using a single diamond, accurately traversed across the stone, with some setups using crush forming to get the shape required.
FWIW they are usually mounted in splelter, which amounts to being low grade shite metal that melts at a fairly low temperature. In theory at least, you should be able to place the dresser face down on an iron block, heat up the end enough to allow the diamonds to settle in the molten spelter, then allow it to cool.
My guess is that about 6 seconds of use will get you right back where you started from, which is with one or more diamonds grooving your stone, which pretty much covers why would not bother.
Have you actually discussed your desires with the maker of the sharpener?

I am assuming you are grinding square nose chain on the Silvey. You might be able to salvage a segment or two of diamond from a spent or damaged pavement saw. I had all manner of dressers for my saw chain grinders and find I dress both square and radius freehand with a brick. It's amazing what 20 years of practice will allow:)
