with small knobs that are hard to turn, here's something to consider. My Jet JJP-12's jointer infeed table locking knob was hard to operate. I tried chasing the threads but it really didn't help. The silly things are only about 1 3/4" diameter which didn't help. I was rummaging in a junk box and found a wheel I'd bought from Grizzly years ago and never used. Hmmmm, I took the PITA knob off and checked the threads 8 m.m. 1.25 pitch. As luck would have it, I have a metric tap & die set. Drilled the wheel out to the correct size and tapped it. MUCH better! Next time I'm at Grizzly or placing an order, I may get another wheel to match. Or, McMaster has something that would probably match.
I move the infeed table fairly frequently when changing between face jointing and edge jointing.The only time I move the outfeed table is when I change the knives which doesn't happen often so the second wheel would be more for appearance than function. Something to consider if you have machines with hard to operate locking knobs, or your grip isn't what it once was. The larger wheel made a huge difference in ease of operation, takes a few minutes and cheap if you have the appropriate tools.
