A picture is worth a thousand words.
This is my set up. A SVST 3° side edge guide with a 3° shim on top (total 6°). The ski base is away from me. I am right handed and I am using a pulling motion. Left to right (top to bottom in the photo.
All my skis are pretty well prepped. So nothing much in terms of sidewall comes off with a swipe or two. What I usually look for is the silver spiral shaped swarf from the cutting. It indicated the panzar file has reached the bottom titanal layer on top of the side edge. On close examination of the ski, I can see the bottom titanl layer getting shinier.
This is what the swarf from the titanal should look like.

When the guide and file setup gets to the tip/tail, just make sure the guide stay in contact of the ski base to maintain the proper cutting angle.
