I always finish my skis with blending in the tips and tails by hand. Both the side edge and the base edge bevel (if the shop doesn't do it.) I like my skis sharp tip to tail.
That was one of the details I discussed with Alain at Taos before dropping them off for a full tune. I have only done base grinds with him previous. He assured me that is the same way he does his skis. He was ex French National team and teched for Tamara McKinney. Hell of a salesman too.
Beast makes a
7° side wall guide. It is pretty crappy. The finish on that piece was atrocious out of the package. Took me about 15 minute of tweaking before I can let it near my skis. The guide is very small too. difficult to get a good grip on it. Threw it in the tuning package for my son when he moved to CA.
For my own use. I put a
3° SVST shim on a
SVST 3° side edge file guide. That setup gives me 6°. Close enough. When I need more, I'll roll the guide over a bit more and I am good.
An
100 mm Panzer file should be good.
A work around for the 6°/7° guide is to put a tongue depressor under the panzer file on a 3° guide. That will get you there.
The panzer/guide combo is really nice and necessary when beveling the titanal plates at the tip and tail. It's great for cleaning up the ragged top sheet edges also.
