I’ve been trying to get rid of the snipe from my Grizzly 12 1/2” planer. When David visited last year, we adjusted on the inlets and outlets and everything else. Then later there was some discussion on LJ’s about adding sticks on the sides of the boards to be planed.
I had an abundance of 1/4” thick pine stickers for stacking my lumber. I tried these on several boards but continued to get snipe. Well to day I figured out my problem I think. I cut new stickers from pine, but I cut them 5/16 thick.
If I hold the light just right, I can see a very minimal snipe that is easily removed with a ROS.
I made this to just fit through the planer at a full 12 1/2” wide with the stickers. As you can see, the snipe is virtually nonexistent. All the snipe is at the end of the sticks. I also found that I had to make the sticks extend at least 4 inches beyond the ends of the board. 2-2 1/2” still left very noticeable snipe.
I tried this on several pieces that I planed down to 3/8” thickness for a box to house my dado stack set. It worked every time.
Try this on your planer and let us know how it works for you
