I can confirm that Starthaus does the rounded sidewall since I bought a pair of skis off someone that had them tuned there. Sidewall was polished too. Just one little prob when you do this - you erase the markings on the sidewall like the boot midsole mark. Shop I had the bindings tested at took awhile to find the remnant.
litterbug, you probably have it set for the blade to be too deep. (Down into the sidewall) That means turning the brass screws in. The screw further away as you pull it towards you, (works better pulling), should be slightly more out, up that is, so that back is lower. But really, screw both screws in till it won't cut at all. That's zero. Then go 1/2 turns from there. You can also try having the front a little lower than the back. If the overall depth is right it shouldn't matter all that much. You should be getting a long curl of plastic from a straight sidewall ski. If you have one of those Frankenskis god knows what you'll get.
Also, the in/out can be set. If there's metal in the ski you'll shave a little of the metal too. Cuts like buttah. Once you get it, it'll be your favorite thing to do if it's a straight sidewall ski.
Honestly, i've had it for years and have wanted to get a better one but it works fine so I put it off. Should've bought that one a few years ago that now some places charge near $200 for. It was half that. It's not the svst one.
Cap skis can smell real bad as you try to cut away. Skips are common. The tool sort of scrapes instead of cuts a shaving. They often have a clear film that melts a bit as you pull the cutter. I'll use the 7deg with pansar file from
Race Place for that often.
The Germans seem to think that everyone grows up with these things.
