Pls don't reply with answers for other fence models---this one is smaller and works differently than the others.
Q1 RE Nut onto the threaded rod at the rear of the fence:
In moving between houses, the nut came off the back of the fence and is lost. The assembly drawing does not state the specs of this nut.
Q1A: Is the nut a locking nylon nut?
Q1B: Or is it a standard non-locking type nut (perhaps with lock washer?? -- although a lock washer is not shown on the fence's explosion/assembly drawing?)
Q1C: How far should the nut be threaded onto the rear part of the rod? The further it gets threaded on, the less rod and thread are available at the front of the fence to accept the knob/shaft assembly.
Q2 RE Assembly and tightening and loosening of threaded rod
In assembling the knob/shaft to the front of the threaded rod, the knob turns 1-2 times before the shaft makes contact with the lever/clamp mechanism and starts to tighten the clamp toward the casting. (I presume I should be doing this with the fence removed from the saw's table.)
The knob never seems to go completely onto the threaded rod.
Q2A: What keeps the knob/shaft assembly locked onto the threaded rod? I considered using some Lok-Tite but feared never being able to get the knob off, if needed, in the future.
Q2B: When loosening the clamp's grip (turning counter-clockwise, the knob and threaded rod work as one unit for a while. But at some undetermined point, the knob turns but the threaded rod doesn't and the knob falls off the front of the fence.
Q2C: What's the proper sequence to assemble the knob/shaft assembly onto the front of the threaded rod so that they work together properly and as designed?
Q2D: Should I be doing something with the spring/washer assemblies during the assembly process? Although I've never taken these out from their original locations in the fence, I wonder if they need to be manually compressed thereby adding some slack into other parts of the entire assembly.
By the way, I am neither talking about 'how to align the fence to the miter slot' nor 'how to use the 2 setscrews at the front of the fence's casting to align the fence with the table slot' or 'adjusting the hex head screws at the bottom of that casting'. This is strictly a parts assembly question for the model 500 table saw's fence.
Thx to all that take the time to reply.
