I like this plane for its feel in my hand. I don't love it because occasionally it gives a metallic ping and I find the lever cap has come loose. The cap does not have a secure stop. I push it down and forward with one hand while rotating the lever cap wheel. There is no apparent detent to keep the cap in place until the wheel locks it down, and no way of knowing the screw anchor is in place. Eventually the cap locks (most times) or the wheel spins and spins. What am I doing wrong?
