Poster: A snowHead

all the guides and videos only ever talk about prepping base edges on new skis, what about bashed up skiss that have hit a few rocks.
I am never quite sure what to do with the base edge when tuning. I have heard once set dont touch it unless you are grinding the whole base but what are you meant to do with rock hits and bad scrapes on the bottom edge?
should you file em out completely and have a slight dip in the base edge or just leave them?

You can only ever increase the base edge angle unless you get the bases re-ground. That's the reason for not touching them otherwise. I just take any burrs off the base edge with a stone and leave it until the base needs a grind. I do all the sharpening on the side edges only.

dont want to change the angles but when i have a very rough/deep gouge in the base when i do the sides only i end up with almost a serrated edge and that doesnt seem right to me...

I know what you mean, but there's not much you can do about it unless you are prepared to increase the base angle locally around the gouge. That's not something I've ever attempted as I usually end up with too many gouges, so the base angle would be all over the place. When the edges get really bad I just go for a base grind and start again with a freshly ground base edge. Usually every 4 or 5 weeks use, depending on conditions.

uktrailmonster, i ended up doing that as well but am still curious what the "recommended" procedure is. do you suffer a rough edge or have a variable base edge

I would imagine the most important things are sharpness and edge angle. So I don't worry about gouges in the base edge until there are enough of them to seriously affect the overall sharpness.

skimottaret, You won't change the base angle by base filing, you would just move the bevel point further in. The bases on all of my skis are at 0.5, I have never noticed any change in the appearance of the bases after filing but they don't feel really sharp if I just do the sides.

Well you can always increase the base bevel angle by filing, but you can't reduce it without grinding the entire base down.

Or you can keep it the same when you file.

If you do too much work on the base edge (assuming you can keep at the same angle) then you'll lower the edge relative to the ski base or start cutting in to the base material.
skimottaret, what uktrailmonster says, so yes, you end up with a marked base edge until you grind it. Occasional polishing with a mod/fine diamond stone ain't gonna cause a problem.
If you have your skis ground I'd recommend initially setting a shallow base edge angle (say a 0.5 or a 0.7 instead of a 1). The benefit is that you can tune it if required to a 1 to take out damage etc with no detrement to recreational performance etc. A racer wouldn't necessarily be happy with this as the ski wouldn't engage as quickly but it's fine for most. As race skis tend to be mostly used on decent rock free pistes their base edges stay in a lot better nick for a lot longer.
I'd did a tuning clinic at the Stoke dryslope today & I tuned a pair of very blunt Equipe's whose base edges were pretty batterered but still achieved very sharp edges. I did a couple of passes with an alu-oxide stone to deburr the base edges & then all the rest of the work was on the side edges followed by a hard gummi down the base edge to remove the hanging burr.

rjs, spyderjon, do you do the base before the sides on skis that havent just had a base grind?
|
|
|
|
|
You know it makes sense.
|
skimottaret, I do on my older skis that I use for course inspection. My race skis are fairly new and still feel sharp enough just using a diamond file on the sides.
I am going to drop off the older ones for a service on Friday, I will see how they feel after this.

rjs, thanks... Jons tuning guide says to do base first but a DVD i have said the opposite. i have been doing bases first, sides and then a deburr which seems to make sense but wasnt too sure.

skimottaret, My theory is that if you do the base first then any hanging burrs that you miss will be pointing downwards and will work for you.

I do the bases first and only if
1, I'm asked to do them.
2, It's skis I've not done before.
3, It looks like they need it.
Other than that I dont do them or I just use a couple of stones rather then all five.
It depends on how they look, I think over working the base will take life out of the ski's.

I tend to leave the base alone too, just taking out any big dings with an Alu Oxide stone.

skimottaret, base edge first but like uktrailmonster I tend to leave them other than take off any raised damage with an alu-ox.

Could any of you highly knowledgable types tell me how/where I can learn to sharpen my edges. I missed spyderjon's tuning talk at the EOSB & don't know where to go to get started on learning a little hands on maintenance. Any instructional vids off youtube or articles off the web would be very much appreciated.
