On most lunch box type planers, the in feed and out feed tables are made of sheet metal and they flex when weight is applied. If either table flexes you get some amount of snipe. I eliminated snipe on my Delta Lunch Box planer when I mounted the planer in a table with a 18 inch in feed table and 30 inch out feed table in addition to the folding tables that came on the planer. Both are exactly level with the base table of the planer. For longer boards I add additional support on the in feed and out feed.
