I wouldn't say these are
secrets by any means. Just things any self respecting skier should know.
Does a regular clothes dryer work? and what temp? what wax?
Sure, it works. Does it work well? Not really. IMO you're better getting a waxing iron with a temp control. They're fairly cheap ($30-50) and will last forever.
Iron temperature depends on what kind of wax you're using. You could get picky and wax according the exact temperature, but lets be real, we're not racers here. You could also just do an all-temp, but you'll hate your life on a cold pow day or a warm spring day.
I recommend getting a cold for frigid/pow days (0-15F), a warm for spring days(40-50F) and an all-temp for everything else. Most waxes are color-coded now, so it shouldn't be too hard figuring out which is which.
whats the best way to apply wax? and do you scrape?
I wax every 5 days on snow or so. Don't let your bases get white, that means they're oxidized and won't accept any wax.
As for technique, I keep it pretty simple. One ski at a time to allow cooling between applications. First, make sure your skis are room-temp before waxing. Next, wipe down the bases with a damp cloth to get rid of any dirt, then dry them completely. Run the iron down the ski to warm them up and pull the old wax out a bit. Do a quick scrape to get the old stuff out, and wipe them down again. Hold your wax to your iron and drip a good line all the way down the ski, then spread the wax across the base being careful not to hold the iron in one spot for too long. After you get good coverage (edge to edge, tip to tail, not too thick), set that ski aside to cool and work on the next one. Once they're both waxed, go back to ski #1 and give it a good scrape with a plastic wax scraper, keeping it flat against your bases.
You can call it good here, or go one more step and buff/brush to really even things out.
These guys are awesome for the job:
Check Youtube if you have any other questions, there's a bunch of stuff on there.
paste wax....yes or no?
Im assuming you mean a fluoro or rub on? Doesn't hurt to have. Just give your bases a quick coat and buff to help if you're getting sticky on the hill.
whats up with ptex? can you fix your own bases?
do the plastic hand held edge sharpeners really work? should i sharpen my skis?
Its nice to have a edge sharpener on hand to keep things maintained, however, Id go to a shop if you want to fuck with beveling at all. For park skiing you'll want to detune you're edges underfoot to prevent catching on rails. I just go over the edges lightly with a file, then de-burr with a gummy stone. If you live somewhere icy, you'll probably want to keep your skis fairly sharp everywhere else.
