I tuned 4 pairs of skis: One really old one (beginner ski), 2 that were fairly new, and the last was brand new.
I went to a couple tuning clinics to see how it was done.
For most of the skis, I basically polished the side edges, hot scraped and then waxed at 260F with TOKO universal wax, then I scraped/brushed (with copper then horse hair brush) the next day. I didn't touch the base edge. All the equipment I used was brand new.
Here were my observations and questions I hope someone can help me with:
1) How much pressure should I be exerting on the plexi scraper? Most of the time, I used one hand and I was probably exerting about 20 to 30 lbs of force. A couple times, near the end of scraping a ski, I'd notice very, very small circular scratches where my scraper initially made contact. But...basically I kept scraping until I couldn't get any wax shavings off at all and I would scrape at least 10 times over the same surface. I was using TOKO universal wax (the white cheap one) and I think that's a fairly hard wax. Should I be exerting more force if I use harder waxes?
2) The old beginner ski had concave? tails (lower on the middle). I noticed this because when I was scraping, the middle still had a thing layer of wax. Does this matter at all? (This is about 6 to 8 inches from the end of the tail).
3) How many passes can I run the hot waxing iron over the base, assuming I kept the iron moving fairly quickly? Almost the entire ski length would still have a layer of liquid wax after several passes. Nothing burned, bubbled, or smoked.
4) What temperature should I use for TOKO universal wax? I don't have the documentation for it...
5) I made a few light scratches on my waxing iron while waxing skis. It tended to happen mostly with the old beginner skis. Does it matter?
6) What grits of diamond stones should I have?
7) On the brand new ski, the base structure was slightly less visible after waxing/scraping/brushing. Is this normal? All the skis took on a much darker/blacker color after waxing, even the new ski. Most of the little scratches that I had on the older skis were still visible after waxing/scraping/brushing. I'm guessing this is normal too?
8) All the skis had the proper 2 degree side edge (I tested by polishing after marking with a permanent marker) except that some of the skis had tips or tails had side edges that were less than that. I know that most places detune the tips/tails but this was happening about 4 to 6 inches away from the end of the tip/tail.
9) How much better/worse is a shop waxing my ski (with the spinning wax roller - not sure what to call it) VS me hand waxing my ski?
10) How many passes should I be doing with the copper and horse hair brush?
Thanks if you made it this far.
