25 CoreBench - Bench Dog Lockable

An economical, customizable alternative and part of a continuously evolving ecosystem, with interchangeable adapters and dedicated accessories.

Bench Dog Lockable

An accessory fixed to the bench using a press and release system.
It can serve as a reference or a simple stop for jigs and workpieces.

Operation
The bench dog inserts directly into a 20mm hole or into the Standard Block , turn the knob and you're done!
The system uses an M6 screw with a hex head closed at one end by a knob with a cover and at the other by a self-locking nut. 
The screw passes through the threaded insert hot-pressed into the tapered slider, which moves up and down, causing the side plates to expand.
The side plates, held by 3 O-rings of 18x2.4mm, lock the bench dog, centering it in the hole. 

	Bench Dog Height	M6 Screw Length
	20mm	60mm
	30mm	70mm
	40mm	80mm

2. Insert the tapered slider
3. Insert the side plates, holding them momentarily with your hand

The best results were obtained with PA6-CF or ABS, but for light-duty work, even PLA was acceptable.
