I've got an older No. 45 combination plane, not sure of the type, but it doesn't have the fence adjustment for squaring the fence to the plane. My question or problem is the Cutter Bolt that secures the cutter against the body of the plane becomes stuck when I tighten it. To loosen it, I have to tap its wing nut with a mallet, after loosening the wing nut. I've cleaned the bolt and the tapered hole it fits in and have tried a small amount of light oil. Still becomes stuck, even if I only snug the nut.
Any suggestions or recommendations to keep it from getting stuck. Overall I'm quite happy with the plane and use it whenever I can, its fun to use.
