There are three different methods you can use to maintain the SkiVisions inserts:
1. Coarse emery (silicon carbide) paper, in 60 to 100 grit or so. Emery paper is good for maintaining all the stones EXCEPT the green stones.
From the Toko Snowboard Tech Manual found here:
The base edge on a snowboard should have a bevel of a half to one degree. A little base bevel makes the board easy to ride and transitioning from toe edge to heel edge without being “grabby”. Base bevel of more than one degree makes the board feel “slippery” and turns have to be skidded because the edge is not close enough to the snow to hook up.
Out of curiosity and a recent discussion with a customer prompted me to perform an unscientific experiment to provide a ‘meter’ for tweaking edge geometry. I think many are over thinking how much is really involved with removing 1° of edge material. It is in fact, fast and easy because little material removal is involved. Hopefully, this will help people to get less concerned about obsessing over angles and experiment on your own.
Sharp and smoothly polished edges, with correct edge geometry (aka properly ‘tuned’) are critical to maximize the carving capability and overall performance of your expensive board(s). What tools and techniques do you employ?
A straight forward, low tech method for measuring base bevels is to use feeler gauges or other objects of known thicknesses (0.5mm, 0.7mm, 1.0mm, etc).
The direct ratio between typical bevel angles, is the metric height (mm) of the angle, at the accepted distance and easy to remember distance of 60 mm/6cm from the edge (actually 57.3mm).
How flat (or not) are my bases? What are my base bevel angles? How straight are my scrapers, edge guides & tools?….are among the typical bits of information needed to perform and gauge quality of work and determine what work is required.
Like any tool we carry, there is a range of quality levels available to meet budget, personal goals and acceptable tolerances. From basic straight metal bars to precise, finely milled, high quality case hardened steel, the DIY tuner can achieve the desired and necessary level of precision using the fundamental tool known as a true bar.
A common question is ‘What are the side and base bevel angles I should tune my boards for proper edge geometry?’ Like many similar subjective questions, one way to find out is to experiment to find out what works best for you.
