I wax twice a week, once before the Wed night race, and again before the weekend. But if I run an iron over the ski after one day of skiing, there's clearly no wax left, no matter what temp wax I used. I've done this (carefully) just to check. So I guess if I really care I should wax before every day of skiing. I'm not going to do that, sorry, way too much work.
Sharpening ... well, I'm getting more used to doing the side bevel, but I'm still afraid to touch the base bevel. I sharpen the sides of the skis before every race. I am learning from verbal descriptions here and in books. It's so much harder to learn this way, but I'm eventually going to know what I'm doing. For instance, I've learned that the file that came with my file guide works best if I put it in the file guide not straight but at an angle. And that the file itself cuts best one way, and not the other (I still can't figure this out just by looking .... there's nothing in the instructions about this, and there are no markings on the file either. I have to keep switching it to see which way it works best, using feel to determine it.)
I have been shy about pressing with the file, but shyness does not lead to sharp edges. After sharpening it carefully last week, I was skidding all over the place out on the hard icy snow. I took the skis to the shop at the base lodge and had them do the side bevels on the machine, and then boy were they sharp to my touch, and boy did they grab the snow nicely. Now I know my gentle touch on the file was way too gentle. Next time I'll press much harder with the file until the edges feel as sharp as the kid in the shop made it feel. I honestly don't know which of us will use up more metal, me pressing harder than I've been doing, or him using the machine. Probably him. I won't have to go back to him again because now I know how much sharper the edges can be.
It's a long process for me to learn this without a friend standing beside me to teach me how. But it can be done, little by little. I think it's kinda like when I re-plumbed a bathroom, rebuilt the shower, rebuilt the floor, rebuilt the wall and door frame because the new shower was too big to get in without tearing a big hole in there. Had to stand around in a plumbing store and shoot the bull and ask questions and read books to figure out how to do the plumbing, but it got done and the leaks eventually disappeared, and the shower worked! Miracles happen, with remodeling bathrooms and skiing too.
When I'm doing this stuff this way, sort of alone and in the dark except for written instructions, I often wonder how many other women are going through the same thing, and how they feel about it. Anybody else going through this?
