You should be able to get both the TOKO and Swix tuning guides as free downloads, for example here
; get both the alpine and the nordic (read all of it, reading's free) as the nordic covers a lot more snow/waxing detail. The printed booklets are worth it for the illustrations (e.g. the wax penetration one in the Toko manual) that are not available in the freebies. swix does an online video at www.swixschool.no
, however, it is not very suitable for fringe conditions such as prevail for the Mid-Atlantic as you kind of have to mix and match techniques from the recreational and the racing pull-down video.
The basic task is not that difficult, the devil is in the details, and the details can be condition specific. Probably the best thing you can do is to keep a notebook of -EXACTLY- what you did to your skis so that you can figure out problems when they occur. This is actually more important when you start sharpening edges, you'd be amazed at how quickly we forget sharpen/don't sharpen/just run a gummi stone down 'em decisions so that we wind up with skis that were last sharpened, oh, October '05.
