Base welding tools and supplies
Hi TaosMath, I can't speak for Tognar's materials, but I assume the ptex string is similar to our welding rod and the ribbon is similar to the welding ribbon that comes in our Pro Fix Base Repair Kit. The welding our base bonder sticks are also similar. The string, ribbon and sticks are basically different shapes of the same material. The string is designed for smearing machines, the sticks for welding guns and the ribbon for hand welding with soldering iron. I like the rod/string as it is small diameter and coils into a round tin, where I also keep metal grip and a small panzer file. Others may prefer the ribbon or sticks. In any case, welding thin layers (1/32"-1/16") versus deep pools of material, will last longer. Let each layer cool and contract before applying the next layer.
The metal grip should be thought of as 'primer' as in painting to be an intermediate material between metal or core materials and the final base material.
My favorite used to be a small piece of surform planer, but find repeated light strokes with the small panzer file, followed by flat filing and/or sanding, quick and effective. This is typically followed by some structuring which can hide slight, inconsequential imperfections.
Coming from a carpentry background and familiar with modifying a variety of other materials, I see ski and snowboard bases as similar to working with wood in terms of sanding, chiseling, rasping/filing, planing scraping & cutting and have used a variety of tools with good success.
If you are tentative about welding and cutting materials. Practice on a gouged piece of wood or plywood. Softwoods like pine are more sensitive than ski bases and harder woods like maple, oak or birch would be more similar.
Here is a quick photo of base supply materials & tool ideas and options.:
Clockwise from upper left: fiber pad, ptex candle, welding wire and metal grip, welding ribbon, bonder stick, Pro Fix iron, metal scraper & sand paper (sanding block not shown), surform section, curved surform tool, 4" and short panzers, coarse/bastard file, small planer, japanese curved scraper, chisel.
A future experiment will be with an orbital sander. I figure if I can sand out fine finishing on wood for doors and cabinetry, ski bases will be relatively easy regarding smoothing out repairs.
