Chuckle, sounds like my 13" craftsman planer. I hauled it to NY a couple years ago and attacked a barn full of dirty (It had been sawed for several years & spent some of that time out in the weather) cherry Rusty wanted to use for Wainscoating in the basement family room of the new house they had built. One set of fairly sharp blades did several ton of that over about a 4 day period, but I did stick Rusty with the cost of a set, about $59 IIRC. Now they are always out of stock, so while the planer is a well built planer, its the last tool like that I will ever buy from snears & takeitback. I built a sharpening jig to hold those over a flat faced rouge stone that runs wet at about 400 rpm, sweet. You can't believe what that can do for a dull hand plane blade! -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
