It makes sense that a clean well maintained base edge should increase the performance. There are tools out there for base edging, and there are videos about it, so there should be an advantage of doing so or people will not even bother, even though they say base edging should not be performed too often, once a year would be sufficient.
I was going to get an edge tuner that can do both the side edge and the base edge. All the tuners that I could see at the shops on the entire street were for side edge only, I believe those were models from this year too. Although I am sure if I keep on searching then Iíll find one for both, I find it strange that only side edge tuners can be found at where the customers have easy access to.
As for the side edge tuner, the ones that I saw were all with preset angles; logically a reason would be for the convenience for the average (or experienced) customers who want to sharpen their own board / ski edges without to worry that the angle might be inconsistent. If that is the case, Iím surprised that I could find no edge tuners for both edges. Thatís not very convenient if Iíll need a separate file for the base edge. From the manufacturing perspective, it would seem that it is a matter of creating another slot for the file to fit into for base edging while making the mould. So does that suggest that sharpening only the side edges would be sufficient for leisure riding? Perhaps the base edge of the skis/boards nowadays donít really need to be sharpened?
Iíve seen videos of how people use a flat file with duck tape looped to create an angle for base edging, which is definitely not preferred for an average customer like myself. Iíd not want to screw up the edge angle.
I actually talked to a guy at a ski shop and was told that base edging is not necessary. He doesnít even do it himself. I also read comments like that online. Again, I do think there should be some boost of performance by doing the base edge. So the question is, is base edging really THAT important? Can it be omitted without affecting the level of leisure riding? Of course for the folks who need the push the speed to the limit would definitely do it.
No, it's not very convenient to need a separate tool to maintain your side edge and base edge tune. It's also not convenient cars are affected by aerodynamics drag, either, but it can't be helped. Base edge tuners are designed differently because there is a larger surface you can lock into and the base edge angle is critical to really determining the feel underfoot. The side edge angle is just chosen to compliment the base edge angle so that the correct corner angle is achieved.
Base edge tuning is pretty imprecise even with experience and a quality tool. The best are the guide sets (FINAL CUT BASE BEVEL GUIDE-1 DEGREE
). The next are shim plate sets or adjustable single purpose tools (PRO SHARP BASE BEVEL GUIDE
or BEAST PRO SIDE GUIDE - 1 DEG
). None of those tools really matter though because you are referencing your base edge angle from your base. What if your base isn't true? Do you have a true bar to tell? What if it's edge high? How do you deal with TBT, Omatic BS tech and all these other things that cause your base reference be erroneous?
Luckily, none of that really matters because we're snowboarders, not alpine racers. Unless you are running gates for time, the type of precision (within 0.25 degree +/- 25%) that skiiers set up their edges with is not needed.
Short answer is have the shop do a tune of it and just maintain it deburred with a diamond stone and hard gummy stone. By the time the edge needs a tune again, your base will probably need a stonegrind which will reset the edge.
