Hi all, i just put new blades in my craftsman 12 inch planer that i just got not too long ago. I don’t have a manual for this machine.The boards kinda jump when they come out and it grooves the last 2 1/2 inches of the board.How do i adjust this out of it.There are holes in the base to stick a screwdriver and adjust the metal rollers and i can’t turn them, anyone with this machine know how to do this?

Thanks for the help

I’m not familiar with your machine but I believe that the problem you are referring to is called SNIPE. One surefire contributor to snipe is an outfeed table that is out of adjustment. To check this, you could open your machine to the maximum (unplugged of course) and use a level or other straight edge to verify that the lower rollers in the machine (or the slide deck if no rollers) and the infeed and outfeed tables are sharing the same line and do not sag under the weight of the outcoming board. There’s a better than even chance that a small adjustment here could eliminate your problem.

Yup, that’s snipe. It is caused by a few things, but generally can be fixed with outfeed support of the board. a little sag when it comes off the front roller causes the end of the board to blip up into the cutter. Also, if your blades are a little taller than the original set, the events that cause snipe are even more magnified. Check the height of the blades with a good caliper. You may have to adjust the gibbs that hold the blade to compensate. I’d try the outfeed support first though.

You could also push another sacrificial scrap through on a sled behing the board you are plaining. It is a work around but helps me when in a hurry…

Thanks, i did have to adjust the gibbs when i first installed the new blades but i do think the out feed is out of adjustment, which is causing the problem..
