Soft snow hides a multitude of ills. I learned that again recently when gleefully skimming along on a few inches of Colorado powder, only to suddenly hit icy, scraped off patches, (thank you, boarder hordes!), and finding not only could I not keep an edge in, I could barely stay upright (and occasionally didn't). So of course I came here and started perusing the "how to ski ice" threads. Lotta wisdom for the taking, which I'm working to digest and put into practice. First and foremost the skier needs to improve, nonetheless, I'll take all the help I can get, so getting sharper edges would be a good thing.
I have a Razor 3-in-1 and some other basic tuning tools, but no bench or vice, and currently live in a place where I can't really set up a full blown home tuning shop inside anyway, and outside is not really an option. Snow is starting to fall on a regular basis, and soon sharp edges will be less of an issue anyway, so was thinking about how I might make do and avoid going to a shop and paying for a tune.
It occurred to me that if I spread some newspapers in the tiny kitchen and worked on my knees on a ski standing upright I could hold it firmly with one hand and use the Razor going top to bottom to apply some pretty consistent pressure. I was actually surprised at how well it seemed to work - much, much better than holding the ski in my lap or putting it across a couple of chairs. Pretty stable, actually. Crayon in some Hertel Hot Sauce all temp wax and buff it in/down with a scotch brite and that's my quick and dirty tune.
Any other heretics out there? ;-)
