DIY: Prepare And Repair  Ski Bottoms. Here’s What It Takes.

Way back when I used to drive to ski resorts, I used to slide a toolbox into the back of the car with everything needed to tune a pair of skis, fix a gouge in the P-Tex and wax the bottoms. The biggest and most important item was my Toko hot waxer.

Between ski trips, each pair of skis received a coat of paraffin dripped onto the bottom, spread, scraped off and buffed. This was done three times and made the P-Tex rock hard as well as providing a base for any additional wax for the conditions or none at all. The treatment also made the bottoms much more scratch resistant.

As a back-up, or to allow someone called children to do their own skis, I had a simple travel iron. Another vital item was a 12-foot extension cord.

Also in the box was a brick of paraffin used in canning. Back before the turn of the century, each box had four, ¼ pound slabs.

In the box there were a collection of P-Tex “sticks” of varying colors to drip them into gouges. They sat in the same tray in the toolbox with a scraper and butane cigarette lighters I’d use to melt the P-Tex sticks and a soldering iron used to help clean out some of the gouges.

Several flat files were in the bottom for sharpening the bottom part of the ski’s edges. To take burrs off and to sharpen the edges to a perfect right angle, over the years, I’d acquired several different “planes” or edge sharping tools. Then once I was finished with the filing I had small whetstones to take off any microscopic burrs.

Most shops have belt sanders to grind off the bottoms and that just grates on my nerves. For one thing, the sander takes way too much bottom off. And two, the sander leaves burrs that need to be carefully filed off. Too much pressure during a careless pass down the belt sander could ruin a ski.

When finished, the edges could slice paper, which if you ski or race in New England a lot, is very helpful.

Every night after dinner, the family’s skis were waxed. My kids started helping around age eight and by the time they were teenagers, they could wax their own skis (!) And, yes, they could feel the difference between a tuned ski and one that wasn’t. The ritual also gave me a chance to check my family’s skis and bindings.

Also in the box was a box of helicoils which can be inserted in holes to enable a screw to be tightened. Having started skiing way back when metal plates were not built into the ski, they were handy to have around.

Ski tuning, or even de-tuning is an art as well as a science. Today, I can’t tell you how often a shop has given me a pair of high-performance rental skis that was desperately in need of a tune-up.
