70mm or 100mm diamond stones

post #1 of 19
Thread Starter 

I'm looking to get some edge beveling tools and would like to buy some diamond stones.  I know the conventional wisdom is the 100mm diamond stones are better.  But it seems that the stones only touch at the ends (due to the curve of the ski edge).  If the stone only touches on the edge, doesn't it make sense to go with the shorter 70mm stones?

 

Thanks,

The idea of an edge bevel is that it is straight not curved. When you use the diamond files, you can use (over time) multiple areas along their face. With the bigger files, you have more options as to what part of the face to use. They are also easier to use than the little ones unless you have a file guide built to hold only the small files-stones.

What I find is important is the width, as vsirin says guides are all different.  I can fit some of my stones into some of my guides and some are two wide.  In particular with base edge guides.  Different brands are different widths too.

   In addition to what vsirin and skimango said, when using diamond stones on your side edge, clamp it in your file guide at an angle--as in not parallel to the side edge. I think you may have been alluding to the fact that, due to the curved nature of a ski with deeper sidecut, only the ends of the diamond stone touch?

     

   Vsirin, can you find a picture of how a diamond stone should look when in a side edge guide? I'm having trouble with S L O W internet...thanks wink.gif

Sorry for not being more clear.  I was talking about side edge beveling.  The "curve" I referred to was the curve of the ski itself (as zentune realized).  A picture of a side edge guide with a stone would be great.  The pictures I've seen show the stone just tilted slightly (almost parallel to the ski) when tuning the side.

100mm. As Zenny said your stone should be placed at an angle on your side edge beveler. this photo is with a smaller stone and you can see how awkward the short stone is. You want your stone as stable as possible on the tool and a 100 mm stone provides a lot nmore stability, since there is a lot more room for a spring clamp and as vsirin pointed out you can move the strone around to different angles and spots so as not to always use the smae path on the diamnds.

 

Also, if you ever want to diamond stone your base edge the short version does not work well (is at all im the SVST tool.

 This shows the large diamond file for side edge filing, which as A-man, stated can be attached with much more stability to the guide than the smaller file. With this type of set up, you can access over 1/2 of the area of the diamond file face over time while retaining a stable connection which gives the 100 size pretty good useful life.

Although, 2 spring clips is overkill and awkward. Makes it much more difficult to hold the side bevel tool. I feel you only need one spring clip and then your thumb directly over the diamond file and edge

Yes, I just use one clamp also. But I took the first picture that Google offered that illustrated the idea.

I know, I was not suggesting you use 2 clamps, just trying to help the OP out!

   I prefer to use the race place's  "side of beast pro side beveler" (kind of a lame name rolleyes.gif) as I have smallish hands that are usually worn out from moving furniture 5 days a weeknonono2.gif...it has interchangeable "plates" of varying degree available--from 1* to 5*,  if I recall--holds files and diamond stones securely. I give it a 4.77 out of a possible 5 wink.gif (cause of the nameROTF.gif)!!

Well if my no moving parts SVST side edge file guide ever wears out, I will have to try the Beast Pro Side Beveler as I have quite small hands. In fact, I can often wear children's L gloves.

   Those svst guides have a half life of a trillion years smile.gif...give or take!

Thanks!

 

This is really helpful.  Next question(s) - which guide (SVST aluminum perhaps)? and which stones (is the plastic on the moonflex a problem?

post #15 of 19
it is the opinion of many, many techs that the moonstones are superior...the plastic is no problem whatsoever...ive been using moonflex exclusively for years, and am one of the techs who would recommend them! smile.gif
swix makes nice diamond stones as well...

vsirin can help you with the svst guides, as i have been using the side of beast for years as well...

Final question - what grit(s) to get???

post #17 of 19
Thread Starter 

I see the swix pro stone have a aluminum backing which might make them last longer, has anyone had problems with the plastic backing?

 

And grit(s) to get starting out? 200,400? 100, 400? 100, 200, 400?

 

Thanks,

With the diamond stones, I have not had any experience with the backs wearing at all. They don't really move against anything or take much unsupported pressure so I don't think it is an issue. The diamond part is what wears out long before the backs show that they've even been used. I also use the Moonflex. I also  have one of the SVST diamond files which has much more tightly packed "grit" than the moonflex and I have not been as happy with it. I think that the spacing on the moonflex faces gives the debris some space to move away from the active cutting that improves overall performance.

 

On the file guide, the SVST is metal, it does not flex, it is accurate and easy to use. The Beast Pro Edge also looks nice and is also metal, stable and accurate. Both have plates that can be added so that you file various side edge angles. I don't imagine you could go wrong with either one.

 

In terms of grit, I think of the 100 and 200 as coarse, the 400 as medium and the 600 and up as fine.  I have all 4 of these as well as one that I think is 1000, A coarse, a medium and a fine should be a good set for most needs. If you were just picking 2, I'd probably go with 200 and 400 if you have a metal file and 100 and 400 if you don't,

good advice.  I would also recommned the 200 and 400, or if only one the 200 (that is waht I use for daily touch up and training).  Holmenkol used to do the aluminum backed ones as well.  Reason was you could buy a replacement diamond strip to stick on it.  They were nowhere near as good as teh moonflex though so save yourself some wasted cash and go straight to moonflex 100mm.  The SVST guides are excellent and totally bombproof.  I would not bother with the additional plates, just get the 93 version, it is all you will need (I also have a 94 but very rarely used and only for bullet proof slalom courses).
