I have a fine old pair of Kästle SG skis
. I've not been able to use them much the last several years
(had to feed the kids instead of skiing), so they are not worn out. I've had them tuned at several places. No one quite matched the factory finish, but that could be all in my head. Nevertheless, I remember the edges being sharp when new, and when they were tuned. You could slice bacon with them.
They haven't been tuned for a couple of years (I mostly demoed bump skis last year), but I noticed that a tune up could be about due, so I thought about bringing them into my local shop, or buying the equipment and doing it myself. While in the shop I asked what tools they had to sharpen edges. They showed me what they used, and it seemed to me that the tolerances I could achieve with these tools were not what I wanted. I also asked what bevel to put on my skis. The shop person said that I wouldn't notice the difference in base bevels anyway. I thought I should take a close look at the tune up I had them do on my yardsale bargains.
I am not impressed with the tune they did on these skis
. Not only did they not fill in a slight gouge, the edges are sharp enough under foot, but they are only sharp for the middle 80 cm; they are dull for the first 75 to 80 centimeters and dull for the last 35 cm
:. I'm thinking maybe that's why these skis pivoted so nicely and did not exhibit the bite I expected from racing slalom skis. My Kästles which have gone three years without a tune and are begining to show slight signs of rust are sharper than thes freshly tuned skis
: . I will not trust these people to tune up my Kästles.
As I said above, I have had skis tuned before, and they did more than sharpen the middle quarter of the ski. So, I guess I have to do it myself or travel long distance, and hope that the same people who tuned it two or three years ago is still there
:. The last person to tune my Kästles came out to ask me if I wanted the factory base and side bevels, or if I wanted to change to a more popular choice. He knew what they were, having raced a pair some years previous. I can't remember what the base and side angles were, but I do remember that the SG HAD a base bevel (maybe only 0.5 degrees?), unlike the SL and SG of the day which was flat.
Ok. Tell me what I need to buy.
P.S. Note to shop owners: Doing a rotten tune on a cheap pair of skis will not make a customer buy new skis from your shop.
