I have a Delta 12 1/2” Lunchbox planer and am doing some thicknessing on some 1 inch poplar to 3/4 inch for a small table. I saw in some magazine a “sled” or similar device, to hold work passing under the cutters and the in and out feed rollers, to prevent the levering up of the work and thus cutting the front and back of the piece. Anyone got some actual description of a sled of this type, and your experieince using it to prevent snipe. Thanks, Tudor Hall

Tudor – check this out http://lumberjocks.com/jocks/Koonan/blog/4733

Also, if you do a search on the sight under “planer sled” you’ll come up with several other entries.

Another option is to cut 2 strips from another board about 6” longer than the workpiece – attach them to each side of the work piece and pass through the planer. The extra length of the side pieces will help compensate for the rollers picking up and pushing down the workpiece and should take care of the snipe.

hope this helps. I’m sure others will chime in.

i use planner sleds all the time. mine are made out of 3/4 solid core plywood with plastic laminate on both sides[flea market find]. your sled needs to be at lest as wide as the wood you what to plan and a little longer. attach a strip of wood to one end [infeed end] so it stichs up about 3/16”. lay the board you want to plan on you sled up against the end strip and plan it.
sleds work good for planning thin stock with a light cut on each pass. sleds seem to minimize snip.
also if you chase your good wood with a peice of scrap of the same thichness it cut down on snip.

You could also make an extended table. Take a piece of 3/4” melamine about 3 feet long by the width of your planer. Center it up in your planer and add 2 cleats to the underside of the melamine. One on the infeed side and one on the outfeed side. This will keep it in place. The longer table may help support the piece better to eliminate snipe. If you are planing long boards you will need to secure it better.

Hope this helps.
