Baladonia Vice Woodworking Removeable Action Bench each vice has two solid steel guide bars which are 23mm diameter with another deep-cut thread screw bar to ensure high clamping pressure is maintained without any slippage. They have fully ductile cast iron jaws that are tapered to allow clamping of slightly out of square stock. Both jaws have holes pre-cast so you can attach your own wooden sub-faces to prevent timber being clamped from marking or you can make jigs and fix them easily to hold odd-shape material. The quick action release mechanism is all steel and cast-iron construction for long life and superior clamping strength. The handles are made of solid 17mm solid steel bar so they will never bend over the lifetime of the vice. A height-adjustable peg is built into the face of the vice so you can use it in conjunction with bench dogs to clamp work pieces above the bench top.
