I cleaned up this plane to use and the depth adjustment knob is very tough to turn, it just seems like it would be smoother? I’m curious if there is something I can check that could be binding? Thank you.

Try cleaning the threads and the knob a bit more to loosen it up. If the threads are clean and the knob moves freely when the blade isn’t locked, I’d try loosening the screw on top of the blade, as that will make the blade harder to move. be careful not to loosen it too much, or it’ll start moving on its own while you’re planing. You need to find a balance.

Is the lever cap on too tight, did you clean the screw and inside of the turning nut, oil it? You should be able to turn it with a finger with relative ease.

I’ve got a MF smoother that does this and I’ve tried every adjustment and nothing worked. It turns great without anything on the frog. Put the blade, chipbreaker and cap on there – total crapville. Drives me nuts, probably an excuse to find another smoother. Not probably, definitely. Or maybe I can learn something from your problem.

And get another smoother.

if it turns freely when the blade is off, and the caps not to tight, I’ve seen the wrong iron with a cap with to small of an opening pinch it enough that its turns hard.

Take it apart. If its fee turning apart, then its probably one of the above. If it turn hard when its apart, the it may be cross threaded, or somebody replaced the screw with a pair of pliers.

One more thing to check after checking what everyone else has said is to look for any burrs on the face of the frog “the part the blade rests on and has the screw sticking up and do the same for the blade. If that fails send up a picture of the frog an blade.

And..if the blade has been ground way back, it can be bottoming out on the frog where the chip breaker screw comes through the back.

thanks everyone. I guess the screw holding down the lever cap was just way too tight. it is much better now. thanks again.
