The bride bought me a 15HH for Christmas and I've had an intermittent problem with wood getting stuck. I finally had enough and decided to investigate. I waited till it happened, shut down the machine and clamped the wood to the lower bed to see exactly where it hung.
So there are two non-driven rollers in the lower bed just below the two drive rollers on the top. I have the lower rollers set fairly low, just a few thousandths above the bed. The bed is very nicely machined cast iron and the edge of the iron just after the first lower roller is razor sharp. The leading edge of the wood stopped right where the casting began again after the infeed roller.
I simply took a file and broke that sharp edge. I made a chamfer of maybe 1/64" and that seems to have solved the problem.
Comments? I can't see how I caused any problems. I know keeping the snipe away is a game of making those rollers as low as you can while still letting them help the wood move smoothly through the machine. So I really don't want to raise the rollers. It seems to be working ok now. I have no visible snipe and I can't feel anything. I'm thinking of getting back in there with a Foredom and making that chamfer a little bigger just to be thorough. I'm also thinking of doing the same thing to the out-feed roller.
I was getting kind of frustrated with the machine but it's pretty sweet now.
I love my wife. I don't drink, smoke, gamble or fool around. But I likes my tools. She willingly indulges my one vice (vise?).
