Poster: A snowHead
|
I’m getting in to tuning my skis and now have a good set of basic tools and a fairly good understanding (courtesy of Spyderjon) on what I should be doing
Some questions:
1. I am still unsure of how to take off the burr (correctly) after sharpening the side edge, I have 2 moonflex diamond stones 400 and 600, 220 grain gummi and an alu oxide stone, I also have the appropriate side edge beveller - factory angles are already set at 89° and I am happy to stay with this for the time being.
I understand the burr created from using the diamond stones will hang over the base edge, I have seen/read various methods and stones described to remove this hanging burr but they are all free hand and I am concerned about either changing the base edge angle and/or blunting the skis by running a stone/gummi stone over the edge that I have just sharpened.
To me the most logical method is to use my base edge file guide with the appropriate stone to remove the burr, this would keep the correct angle (89°) but I have not seen one video, article or forum post describing this method so I assume there is a reason for that!
2. What stone should I be using to take off the burr?, I have read/watched advice that suggests using just about every stone available to remove the burr – ceramic/diamond/Arkansas/gummi/alu oxide
I am off skiing in July so have a few weeks to get it sorted, many thanks for any advice
Regards
Jason

@Fish_Head, the burr is created when you file the edge (rather than diamond stone) as far as I understand it.
I normally just run a hand held gummy stone gently along the base edge held flat against the base.
So file (if needed) to sharpen, smooth and polish with diamonds and remove burr with gummy.
I would use the alu stone for damage repair when you hit stones and you get case hardened dings.

Use your 600grit Moonflex to remove the hanging burr. Yes, you can use it in your 1 degree base edge angle guide but it's dead easy to remove the hanging burr by hand. Leave the ski positioned in the vice as though you were working on the side edge angle (ie ski on its side with the base away from you) and place the diamond file on the base edge angle with about a third of the diamond protruding above the side edge. Use the diamond 'dry' & hold it flat on the base and then tilt it a 'whisker' so that it's flat on the base edge. Now push it slowly down the length of the ski (not back'n'forth as that action is not as stable) whilst apply light to medium pressure on to the base edge. You'll feel a slight resistance from the hanging burr as you go. Check that the hanging burr has been fully removed & if there's still some burr present then repeat the process.
Then hold your gummi stone at 45% to the edge and run that very lightly down the edge.
I'm posting this off my phone but I'll post some pics tomorrow.

A hanging burr can be raised/cut with either a metal file, a diamond file or usually a combination of both. It's just that a diamond usually removes less material (depending on the grade).

@Fish_Head, I think while you were replying to @Sledger @Spyderjon has answered your question above...

That's exactly what happened
Thanks for the info Jon, I thought better to post on here so others can benefit from any advice
I'm assuming if the side edge just needs a touch up then the 600 diamond stone will do the job

After doing the side edges I flip the ski to be base up then use the base guide and diamond to deburr rather than by hand. Seems to be more logical to retain the edge angle by using a base guide as 99% of the time the next step is to put some wax on.
I can't think of any downside to using a base guide if you are going to wax after a sharpen.

I always put a bit of tape on the 600 and do a pass down the base edge before doing the side edge. Doesn't this normally take off the burrs? Basically Method 2 above. I don't do the 45 degree gummi after. What is the consequence of missing that out?

And love to help out and answer questions and of course, read each other's snow reports.

Erm, but there won't be a burr on the base edge before you do the side edge (maybe some damage you clean up with a pass of the alu oxide stone, but not a burr). You start off with a burr on the side edge caused by skiing, then you file/diamond file the side edge to remove the burr and sharpen it, which creates a burr on the base edge which you then remove with the diamond file which potentially creates a very small burr on the side edge which you finally remove with a very light pass of the gummi at 45degrees.
Correct me if I'm wrong...

Yeah, sorry I was talking about a burr from dinging a rock not a burr left from doing the side edge. Mentioned here
Is me not removing the hanging burr after edging the reason I ski so sh-it?

You know it makes sense.
|
Is this really worth worrying about if you are not racing? I would think one run down a boiler plate piste will sort your burr out.

@Themasterpiece, It isn't even something I worry about when I am racing.

I just do a final pass with one of spyderjons 1500 diamond files in a base guide Call me pedantic when it comes to tuning.

1500 diamond file? Wouldn't it be cheaper using Brasso on a bit of card
