I gave some serious thought to using that method, but found it was hard (for me) to keep a consistent 30 degree angle. Of course, there's the
Work Sharp Tool, but it sounds like you have a lot of blades to sharpen... probably more than would make sense on that little unit.
What I've used instead for many years is a bench grinder and a jig to hold the blade I want to sharpen. For the jig, I cut a piece of 6x6 down to about 16" long, and cut a shelf most of the way down on one side (from end to end) to rest the blade. Then cut the base to the proper angle and height to achieve the desired grind. Clamp the blade in the jig with a C clamp, and slide it back and forth across the grinding wheel. I have two jigs with different heights and angles that I use for different blades. I wish I had the ability to post a video (I don't, being a Neanderthal), but if you can imagine the correct position and angle of the blade where it should meet the grinding wheel, I bet you can come up with something that works.
Sorry I can't do a better job of describing the jig. Let me know if you want more info, and I can try to take a picture (no guarantee on the results).
I really wanted a high end professional sharpening system, but for next to nothing in out of pocket expense, some experimenting and using scrap lumber, a couple of hours of effort yielded terrific results.
