I have been using these roller guides by Husqvarna for 3 years they are well worth using all the time the method of holding the file is not governed by pushing the file it will go through the process without being pushed you just let the file run natural against the tooth
@@2nostromo You can count on 4 strokes on each tooth. At least 2 strokes to get the filing going and then one or two more to get underneath that chrome plating. Actually you should not use a file handle like in this video but a round handle, and then rotate the file, as he did in the video, but keep rotating it, round and around.
