Hello all,
I have a question about lever cap screws and their proper tightness. I have a Lie Neilson no.4 and I cant get the blade to adjust properly. It moves a little, and I mean a little but the adjuster knob locks up tight. How tight should the lever cap screw be? After I sharpened the blade I put everything back together and maybe I tightened the screw down to tight. I need a good source of information on how to properly set up the plane after taking it apart.
Any help?

The rule of thumb (pun intended) I’ve heard is that the cap lever should be stiff, but you shouldn’t have to hurt your thumb snapping it. Too tight and it will make adjustments difficult. Too loose and the blade can shift or chatter. I’d play with tension and see if it helps your issue. On a new LN, you shouldn’t have any issues. If you think it’s a plane problem, give them a call.

Also, don’t tighten the screw after you’ve snapped the cap; adjust the screw then snap it. Much easier to tell how tight it is.

How tight should the lever cap screw be? Not that tight. Tight enough that the blade doesn’t move on it’s own, but loose enough that you can adjust it with the depth adjuster and lateral if the plane has one.

Lie Nielsen has some very good youtube videos and in many of them they’ll even suggest a certain number of turns of the screw, say a quarter turn to give the tension you need.

Have your say...
