If the torque on the Diamonds is 15 lbs, what should it be on a Gabriels carom?

I believe the Cobra says 12ft/lbs.

Not sure if he has factory info or its his gut feeling.

I asked Verhoeven the same question and they couldn't answer it. Or wouldn't for some strange reason.

Because no table manufacturers have ever recommended a rail bolt torque. The torque is specifically determined by the rail bolt anchor system, not the torque specification of the bolt used! Using T-nuts for anchors like Olhausen installs in their rails won't hold up to a higher torque specification compared to a GC3 or newer, or a Diamond for example. All billiards tables that use the threaded inserts, or the floating nut plate need to be set at 15ftlbs torque.

Ya, years ago I was setting up torque control power tools at a tractor assembly plant and one of the parts was a rubber clamp sandwiched between 2 metal plates, the bolts were something like an M8. The torque spec was for a M8 Grade 10.9 from some bolt chart. Not only could I not reach their torque spec. with my tools, when I got there using a digital torque wrench, the rubber was completely flattened/extruded. Ugly looking assembly.

Suggested to the ME to revisit the spec and get back to me.
