I serioulsy doubt the OP's skis have an accurate 1 degree base bevel.. A true 1 degree sksi beautifully, no slop. Most people over base bevel thier skis. Period!
I have a brand new pair of Atomic D2 Race Gs that came from the factory with a perfect 1/3. (I also have many of my skis tuned to a .7/3 and some .7/4.
The Atomic skied right out of the box gorgeoulsy! Maybe the best tune I have ever skied!~
A gummi stone should not be used to remove the hanging burr. Gummi's are too soft and if used in that manner can overlap the edge point and actually dull the edge.
You need an arkansas stone for to remove the hanging burr and you defiently do not need a bevel guide to remove the hanging burr. It is that simple! You can't ruin your base edge angle with a NON-CUTTING stone unless you accidentally roll it up and over the edge, which is pretty damn hard to do, unless you are really uncoordinated and probably should avoid skiing all together in that case!
Neither should you ever use any sort of cutting stone (diamond or otherwise on your base edge once the initial base bevel is set to the desired degree. All maintenance is done on the side edge.
A gummis most usefull as the absolute final step used at a 45 degree angle to the edge point WITH ABSOLUTELY NO PRESSURE. this will leave an ultra smooth sharp particle free edge point.
Contrary to the above posters, if you don't remove the hanging burr after side edge work, your skis will be damn near unskiable.
If anyone here enjoys skiing a pair of skis with a hanging burr, I really have to question their understanding of how a ski should perform, or their ski ability itself!
