I've had this no. 18 for a while and never have been able to get the lever cap to fasten securely. I've seen a little info online that the lever cap on mine, which is the early style, isn't all that great so didn't think I'd have any luck sorting it out. I took a closer look at it and it seems you have to have the lateral adjuster screwed onto the lever cap screw at just the right height. That at least made mine work a lot better. Does anyone have experience with this plane and can tell me if I'm on the right track in getting it to work properly? It still isn't great but at least it will close and seem somewhat secure at this point after getting the lateral adjuster in a better position.
