The detail is whether the bridge handle is supporting your cue stick or your bridge hand. You could put your stick on the bridge and then form a normal rail bridge over the stick. Then the stick would be supported by the bridge. If you formed a bridge on the mechanical bridge, the mechanical bridge would be supporting your hand which would be supporting your cue.
I prefer the "let them just play" policy for this.
I get that detail. The OP phrased the post with an either/or so I tried to cover both scenarios:
QUOTE FROM OP:
“From there, the player could either rest his cue on the bridge stick for a reach shot or rest his bridge hand on the bridge stick for an elevated shot.”
MY BCA INTERPRETATION:
My take is that BCA would forbid any manner of which the bridge hand is being elevated through equipment of any kind (1-3-1-e). Without the bridge hand, BCA has no explicitly written rules requiring you to use the bridge head vs. handle. As I said, without the support of a bridge hand I don’t see why you’d want to try to just free slide the cue stick on the rest handle.
MY WPA INTERPRETATION:
My take is WPA would forbid it as an unintentional use of the equipment but it takes a little digging to arrive at that conclusion. It’s not addressed in the main rule book but the equipment specifications document seems to specify intended use of the mechanical bridge:
QUOTE FROM WPA:
https://wpapool.com/equipment-specifications/#Mechanical-Bridge
“18. MECHANICAL BRIDGE
The mechanical bridge, also called rake, crutch or rest, is an accessory of the billiard sports table and consists of a stick with a bridge head mounted at its end to support the shaft of the cue stick replacing the hand bridge during shots difficult to reach. The stick or handle of the mechanical bridge is very similar in shape to the cue stick. The bridge
head has notches or grooves, usually at various heights, in which the cue shaft can rest. The contour of the bridge head should be smooth in order not to mar the cue shaft or rip the threads of the table-cloth when being used.”
MY WPA INTERPRETATION CONTINUED...
It seems clearly stated the intent of the equipment is to replace (not supplement) the hand bridge. Now whether the shaft must rest in the grooves of the bridge head is not clear. It seems to say the cue can rest in the grooves which reads to me like “can, but not necessarily”.
PARTING COMMENTS:
Overall I like your “just let them play” mentality. But if I was in the World Pool Masters and played a tree-top safety, I might expect the rule enforced if it is going to read that way.
