I made one of those chance discoveries that helped me in an unexpected way today. I make cutting boards for gifts and I use my planer to flatten the first glued up panel. For quite a while I have used a tip I saw on the wood whisperer where he uses hot glue to secure a panel to a flat board. The tip has always worked well for me with good results except for the expected snipe. I’m too cheap to buy long enough boards to just cut away the snipe so I have just lived with it. I’m pretty good at reducing it by applying the correct pressure on the infeed and outfeed. Today, I only had a really long piece of mdf shelving material to use as a sled. It’s five feet long. I didn’t want to cut it because I want to use it later so I glued the panel to the middle of it. It’s much more unwieldy to run it through the planer but I found that it nearly eliminates the snipe. I’m sure it’s due to the amount of weight hanging off both ends of the panel helping it not lift so much. If you can handle using the longer boards as a sled, this trick works pretty well. I will keep using it.

You can also double side tape skinny strips on the sides that are longer than the board and the snipe will be on the sacrificial strips.

I adjusted the in feed and out feed tables with a straight edge so they were dead on even with the tables and have had no trouble with snipe since.

I have used the skinny strip technique. Can’t do it for the cutting boards though because I like them as wide as the planer can handle.

With my old Delta Planer that had a significant snipe problem I found that feeding a piece of narrow scrap, the same thickness as my good board, and then starting the good board into the planer before the narrow piece finished being planed kept the snipe on the narrow board. I did the same when the trailing end of the good board was about to enter the planer. I would put another narrow board of the same thickness into the planer before the good board finished. The good board would be snipe free, and the two narrow boards would have the snipe. Planers with two or three posts have the most problems with snipe. It is caused by the ability of the cutter head to rock slightly as the feed rollers ride up onto and down off of the board being planed. The cutter head tilts slightly, causing the cutter to dig deeper into the ends of the board.

I replaced my Delta planer with a DeWalt 735 which has four posts and a locking design that prevents this type of cutter head movement, and the snipe on my boards is now almost non-existent. Where the snipe line would be there is sometimes a faint line, but a few swipes of 150 grit paper will completely eliminate this line.

I gave the Delta to my son-in-law, along with the training in how to minimize snipe when using it.
