I'm in the middle of rebuilding my bench and need a bit of advice.
I have an 8 ft bench that's a torsion design with all 2x6 construction and a 1.5" plywood top - it's solid as a rock.
I've been using Inline Fab's Quick Change mounting system and it's a perfect solution for those of us with a single bench.
However, I have added a 2nd Dillon 650, which I don't plan to take on/off like my turret and single stage presses.
My goal is to have a separate/dedicated 650s for both small and large primer calibers.
I want to incorporate flexibility into my bench mounting - essentially, I want to move the 650s to the end of the bench when I'm not using them, but without taking them completely off to be stored elsewhere.
I've looked around quite a bit and it seems that other reloaders either utilize a T Track system or threaded T nuts to fasten presses to the bench in various places.
My idea is to utilize the Inline Fab mounts, but simply move them where I want them with a track system or permanent T nut locations (countersunk into the bench top).
Some of the T Track systems I've seen on YouTube seem to have quite a bit of movement at the bottom of a press stroke, especially when sizing larger brass. I do not want to introduce any movement to my current system.
For those of you who use a track system, do you sacrifice any of the natural rigidity in your bench?
The other solution is using the threaded T nuts that are sunk into the bench top. However, some say it's possible for them to loosen over time. That would present a new set of problems if accurate.
Does anyone have any experience with using threaded nuts?
These are the models that have been suggested to me:

Finally, is there another method that I haven't mentioned? I have considered drilling all the way through the bench and using a bolt/nut solution, but don't really want to drill through the 7 inches of plywood/2x6s on the front two mounting holes on the IF mount.
Here's a fairly recent pic of my bench (obviously prior to the second XL650 addition)
