Hi,
I'm trying to set up an adjustable (height) platform for a table saw. My thought had been to do something similar to the router lift mechanism from shopnotes issue #121. Essentially using a threaded rod that runs through a coupling nut and raises/lowers whatever when the rod is turned.
The problem that I ran into is that I ordered 4 3/4"-10 threaded rods (one for each corner of the platform) and coupling nuts but I can only screw the coupling nuts on half-way. That makes sense since the idea behind a "coupling nut" is to extend rods by coupling them.
In the shopnotes issue #121 router lift the rod (in their case a 3/4"-16) is able to run all the way through the coupling nut. For those familiar with the router lift (Steve Ramsey also built one and has a video on youtube about the build) the coupling nut is epoxied into the pieced that holds the router. The router can then be raised/lowered as the rod is turned.
So my question is: Is there a "special" coupling nut that would allow me to run the rod all the way through? I don't want to order 4 more and run into the same problem.
Thanks,
Rob
