Not being an ice skater I had no idea they sharpened ice skates so I took a look at you tube. There are several basic overviews,
I watched the one with guy on a cruise ship(!) and it was very informative.
I understand "will" and this is a site where will and way meet. But it does take some basic hand tools, and like a welder, grinders and knowledge to use them. And please I hope you don't get offended because I have asked this of guys.
I think I could make something close with a 4" angle grinder on a fabricated pedestal and it would have to have the wheel dresser built into it as that's really crucuial
To the whole process. The skate mount could be made out of heavy angle iron slotted for adjusters so you can center the skate to the grinder stone, with another angle
Bolted to the angle to clamp the skate blade to. I think a good piece of Formica would be a sturdy enough top and with felt on the bottom of the skate mount would slide just fine while grinding. There are several points that need to be done precisely like the grinder mount probably needs an adjustment to make sure it's parallel with the table. The other tricky thing is grinder stones as they don't mention how fine of stones the Blademaster uses. Typical 4" grinders use like 40 grit I believe.
