    I believe it was Ed who talked me into purchasing this system about five years ago. The cost was substantial... but to me, it was well worth it. Learning how to use a disc well (for me anyway) represented significant evolutionary advancement in my processes. Unlike Ed, however, I much prefer the flat discs. I find that my 1-deg disc primarily gets used as a template for cutting sandpaper discs.

    I've heard that same thing from a few others....liking the flat discs better. I do admit that there are some applications where I prefer the flat discs, but those 1 degree discs really shine when it comes to longer blades.

    I'm assuming the 1* bevel is very helpful for gyutos and other long kitchen knives?

When I say a love/hate relationship, the challenge for me has been that I can't get my abrasive paper to last very long. I use a rubber belt cleaner, which helps.

    I suppose I've never gotten 100% proficient with mine but I honestly don't know exactly what to do with it. I have used it primarily to flatten scales after re-sawing and to remove mill scale / scratches in my blanks before heat treat. I go through periods where I use it quite a bit and then I get unhappy with it and it just sits for a few months. I'd really like to get more out of it.
    are you variable speed? for me, lower speed means longer disc life and easier handling. I usually run my disc grinder at 375 to 550 rpm. the Nielsen system sounds good, don't know why he doesn't post prices. I use 6" and 8" lapidary polishing heads. the Rock Shop in South Dakota has a similar system http://www.therockshed.com/equipment20.html

    Hey Scott- yes I do run a VFD, and typically at pretty low speed as you mentioned.

    When I first saw the Nielson system I thought it was pretty cool, but once I got pricing I knew it would not be in my future. In searching for an alternative system of switching grits, I found 3M's feathering disc adhesive that makes multiple discs unnecessary as you can just switch out the paper anytime you like using just one disk. Here is a video showing a switch.

    Awhile back Rod offered a group buy with a big DISCount (see what I did there?). I was considering asking him if he would be willing to do another. I have a KMG disc with 1 and I love it, although it takes a learning curve. I spritz the disc with windex and I have one of Ken Coats liners on it. I'm kind of stuck between getting the Neilsen set-up, or just getting another dedicated flat disc. I would be about the same price.

    About the same price? I paid $89 for my Beaumont Metal Works disc and was quoted $370 shipped for a Nielson hub and one disc. Not quite the same in my wallet.

    And $240 for a VFD and another $210 for the motor comes to a grand total of $539, so yes the Nielsen would be cheaper, but I wouldn't have two dedicated machines, which may be nice.
