First tune on 2014 Blizzard Bonafides

post #1 of 5
Thread Starter 

I'm wanting to do a basic edge tune on some Bonafides for the first time and am wondering what angle these are factory set at. I read 1/3 somewhere--is that one-third of one degree? If I'm not wanting to change the edge angle can I use a diamond stone and sharpen these at 0 degrees, or is 1 degree (both bottom and side) closer to the factory setting? Also, from what I've read, a diamond stone is enough for a good sharpening so long as the edges are in good shape? 

 

If I do want to change the edge angle and don't have a planer (I think that's the tool), can I just go at it with my edge guide at 2 degrees on the side and 1 degree on the base? Obviously I've got some things to learn. Thanks!

That's right.  The base angle is 1 degree and the side angle is three degrees.

What you need is a fixed 3 degree (also called 87 degree) side edge file guide, some files and a set of stones.  For now I would just sharpen the side edge at 3 degrees. 

 

Coarse file only if needed (due to edge damage or changing bevel - you're not changing it I don't think), fine file use sparingly, progressively finer stones to polish. There are plenty of threads on this in the tuning section.  You should read them.  :)

Thank you!

Work the base edges only to remove protruding burrs.  Leave any nicks there.  Leave any other base edge work to the shop when you get the bottoms stone ground.  You do not want to remove metal and end up with the base edges lower than the base material.

 

Work the side edges as little as possible to remove burrs.  The amount of steel remaining in the edges is one measure of the remaining life of the ski.  I leave small nicks in place and just remove the upstanding burrs.  Keeping them sharp takes little steel away.  Get the guide as Ghost said.  Get medium and fine diamond files.  Use a light touch or you'll lose the diamonds.  Darken the edge with a felt tip pen (Sharpie, etc.) File from tip to tail, medium file first, then fine, removing just enough steel to remove the ink and get the sharp edge that will scrape off some thumbnail.  Maybe also get a fine stone and finish with a few strokes of that.
