I purchased a FK/SKS sidewall planer form Spyderjon.http://forums.epicski.com/attachment...d=122116502 0
I have 4 different sidewall planers, and this one by far, without question is the best sidewall planer/ski tool i have used. I could not find one here in the States and Jon was nivce enough to sell me one. I would highly recommend you contact him and buy one of these. Atomic skis are partiuclarly difficult to cut back (since they are predominately a CAP configuration and the Aerospeed threads are ingrained in the sidewall)and this one wokrs the best.
I also back file with a 7 degree bevel guide (www.artechski.com
sells a 7 degree or you may be able to get to 7 with your SVST and shims depending on which bevel angle you bought) and a short Panzer file before setting edge bevel.
If you are using a 3 degree side edge you really must cut back the sidewall quite a bit to get to a true 3.
also you didn't mention using any gummi stones.
I also recommend and I always tape my bases when doing any sidewall work, an absolute must if you are going to file, but als protects the base from the repetition of the side edge beveler plate rubbing against your bare base. I prefer the wider Holmenkol tape, since you only need one strip adjacent to the edge you are working on to protect the base. this will a keep any stray filings from gouging the base should one get under the bevel guide plate. i also use a paint brush and sweep the ski base and edge between each pass to be sure there is no edge filings or sidewall material laying around on the ski or on your tools.
