Scuff up the damaged area with sandpaper or a wire brush, then wipe away any debris with a cloth and some base cleaner. If the gouge is deep into the wood core, apply a very thin coating of epoxy to the damaged area, being careful not to build up too much around the edges. Keep the board base up and let cure. Core Shots. A core shot is when the core of the ski is exposed to the elements (water, moisture, snow etc.. ) instead of being protected. Now that the ski is clean you are going to need base weld or sometimes called metal bond. Ptex is a texture mapping system developed by Walt Disney Animation Studios for production-quality rendering: Ptex applies a separate texture to each face of a subdivision or polygon mesh. The Ptex file format can efficiently store hundreds of thousands of texture images in a single file. Core Shots and Deep Gouges A good marine-grade waterproof epoxy, or a reinforced epoxy product like JB Weld should be used to patch the core first – you may need to cut and remove even more of the base before you can do this work. A core shot describes the degradation of strength in a section of climbing rope. A loaded rope rubbing over a single sharp crystal can quickly slice through the protective sheath and pluck away the critical core strands.
Sintered p-tex is made by packing ultra high molecular weight polyethylene powder into a cake that is heated and compressed (sintered) to form a log or billet (see diagram below). A lathe or mill is then used to shave (scive) off a thin layer to the desired thickness.
On a base weld, they remove the base around it and cut out a shape, and just put a new piece of base material in it, and make it flush with the rest of the ski. It won't crack, do you definitely just got a ptex drip in that. 8 years ago.
P-tex is the abbreviated name for Polyethylene. For snowboards and skis the form used is UHMWPE or Ultra-high-molecular-weight polyethylene. It's the same material used to make bullet proof jackets as well as hip and knee replacements.
Cut a piece of replacement edge a bit longer than the gap, and use a file to trim it to a snug fit. Put a thin coating of epoxy between the edge and core, and then place the edge in line. Fill the holes with epoxy, and tighten down the edge with a handful of fine finishing screws, being careful not to strip them out.
How often should I get a tune-up? Ski 'N See shop technician, Ryan Mazzella, suggests that you tune your skis after every 15-20 days of riding. However, this varies for each skier. If you tend to beat your skis up more than the average rider, you may need to bring them in for a tune-up more often.
Do scratches affect the performace of the board? scratches will affect your boards performance. big scratches will need to be filled with p-tex, which is plastic (either sticks or granular) which is melted into the deep scratches.
