This is a question about using a jointer. I've had my Ridgid 6" jointer for about 5 years. Early on I only used it for edge jointing since I bought s4s lumber and never had a problem. In the last couple of years I've been purchasing rough cut lumber from lumber yards. My problem is face jointing. I've checked the machine set up many times. The infeed and outfeed tables are coplanar, the blades are still fairly sharp and top dead center is still at the height of the outfeed table. This morning's work demonstrates my problem. I was trying to face plane a piece of 4/4 18" long Bloodwood. It was very rough but pretty flat with no appreciable cup or twist, so I took several passes on the jointer. It was set to take off 1/32". I used the push block that came with the jointer on the front of the board and a Gripper with a drop down hook on the back of the board. After the 3rd pass i'd only planned about 3/4 of the board and the front of the board was thinner than the back, giving the edge a triangular profile. (See attached photos) Since the machine seems to be set up right, but the end result is wrong, that tells me that I'm broken. My guess is that I'm not applying the proper pressure at the right places as I feed the board across the cutter head. That, or, there is a problem with the machine but I don't know what it is. This is driving me nuts, not to mention the cost of the wood that I've ruined trying to work it out on my own. Has anyone else had this problem and learned how to correct it? As always, any suggestions are greatly appreciated.
