And remember, only light pressure when running off the tail see above. See Ski Base Flattener for a thorough discussion on flattening bases. They are caused by the manufacturer not letting it cool and age before grinding it, or by shipping it in very hot cargo carriers. Regardless of the reason, the concave sections need to be removed for it to work right. They may look great when new, don't be fooled. Oh, and when you go to the shop to buy, take your true bar and inspect a ruler will do if not too flexible.
Buy the one with the flattest base and save yourself a lot of trouble. The File Base Flattener is the only hand tool up for the job. It is powerful you can easily put 50 to 60 pounds of pressure on the tool and uses a very sharp double cut file designed to simultaneously cut plastic and edge metal. It is the "heavy machinery" of hand tools. When factories grind skis and boards, they chase speed and efficiency. Unfortunately, that also translates into work hardened edges and plastic caused by too much speed and pressure with the stone, and it can become a real challenge getting the tune on a new ski or board right.
Hardened steel edges are hardened on the surface only, about. But, until it is removed, files, carbides, or steel will not cut it. It is best removed with our 4 inch green stone with tape wrapped on one end for bevel.
Whenever you have concave bases you generally also have hardened edge sections. If you observe that the File Base Flattener isn't working, that is, isn't flattening the base, you have hardened edges. You can tell when the edges just seem to get slick and shiny but aren't getting cut with the file teeth, because they can't.
Sometimes it is a good idea to mark the concave edge sections with a felt tip marker so you can concentrate on those areas and watch your progress. An optional 6" coarse structure stone is available. This is my second Ski Visions planer. My first one had a narrow blade for the old straight skis. I am an experienced shop tech with over 20 years in the industry. I bought the tool as an alternative to having a shop grind my many pairs of skis. I watched the video from the company to get the recommended procedures and grabbed some boards to work on.
It does take some effort and a lot of passes to get a ski flat the first time around with the tool. I used the medium stone supplied and tried to stop often to brush away the base material that the tool cuts. I switched the stone for the steel cutting bar occasionally to cut the "hairs" left and give me fresh material to work with. After about 45 minutes I had a flat ski and reasonable structure showing.
I'm a bit concerned with the lack of a true pattern in the base, but time will tell. I've put storage wax on the skis to see how well it soaks in.
I'm heading to Timberline in a few weeks so I'll wax for the summer slush and update once I've skied on this par. Valuable tool that allows a high level of tuning on a home bench. Highly recommend watching the videos available on the Tognar website with instructions on how to properly use this tool.
I have been using it on my skis most of this season, typically after about every five to seven days on the snow. However, once the ski is flat and structure has been made on the bases, only minor touch up is needed.
I think I prefer it to even having access to a base grinder, with a skilled tech. It's easy to use and control and, used as shown in the instruction vids, you don't risk over doing it. Love the way my bases take and hold wax with the additional structure the tool has allowed me to put on my bases.
Works as advertised. Does a really nice job of structuring the base for a nice glide. I knew my bases were not flat but didn't realize what a difference it would make in the way they ski.
Very happy with this product. Strong claim? But true. We don't include instructions with the tools; the instructions are in this website. The instructions are updated several times each year as we get questions from customers and realize that the instructions can be improved. We ask our customers to review the instructions periodically for changes and to refresh their recollection, there is a great deal of information in these instructions, much of it is easily forgotten.

I have been ski tuning over 40 years and have been making SkiVisions tools for over 25 years. If you are using a SkiVisions tool, I probably made it. I started SkiVisions because I was very dissatisfied with the ski tuning tools then available. They were crude, cumbersome, imprecise and ineffective on the then new sintered base skis. I wanted tools that were quick and efficient to use and produced precise results, so I had to make them myself.
