I’m now down to the last short strokes to getting my jointer restoration over the finish line. I have one remaining issue to resolve though and that pertains to the cutter head guard. I’ve attached a couple of photos to help illustrate the problem. The parts photo shows the hardware on the left side that came with the new jointer retro kit I purchased from an EBay seller. The assembly on the right side of the photo is the existing guard, mounting post and knob. The other photo shows the exploded parts diagram for the new cutter head hardware.
The issue is that the existing knob won’t attach to the threads on the new mounting bolt shown on the left. The existing mounting bolt or post has vertical, knurled threads. The threads inside the knob show lots of wear. The existing cutter head assembly works fine but since the new hardware came with the retro kit I would like to use it if possible. It seems to me I could stick with the old adage, “if it ain’t broke don’t fix it”, or get a new knob that is compatible with the new hardware if that is even possible, or upgrade using the Shopsmith feather guard retro kit. Has anyone else faced this issue before? Any suggestions? Thanks.
