Mount Vise To A Secure Workbench

1.

Place vise on the workbench to identify location of mounting holes.

2.

For added strength to the workbench prior to installing and securing vise, place an

18” x 18” x 2” piece of wood (18” x 18” x ¼” metal plate) to the underneath side of the workbench.

3.

Mark and drill holes through the workbench and wood / metal plate using the swivel base as the template for the mounting holes. Prior to drilling, make sure area is free & clear of any hazards.

4.

Install proper length & diameter bolts into the swivel base of the vise. Yost recommends at the minimum the following configuration:

Install proper length & diameter bolts along with flat washer through the swivel base of the vise. The bolt should be long enough to protrude at least 1” beyond, the underside of the workbench and wood / metal plate. On the underside of the workbench and wood / metal plate, place a flat washer, lock washer and locking nut to the bolt. Securely tighten vise to the workbench. Periodically, recheck and re-tighten the nuts.

Vise Operation

Make sure vise selection (size and type) is appropriate for use and application. Larger vises are readily available through Yost Vises. Never force or use cheater bars, pipe extensions on the screw handle of the vise as this places excessive pressure on the vise components and they may fail resulting in severe bodily injury.

Step 1: Make sure vise is securely mounted to the workbench.

Step 2: Make sure the swivel base lockdowns are secure.

Step 3: Open the vise by turning the vise handle counterclockwise. Do not open beyond the vises rated capacity (jaw opening).

Step 4: Place item between the serrated jaws of the vise.

Step 5: Close the vise by turning the vise handle clockwise until the item is snug between the serrated jaws.

Step 6: Continue to tighten the screw handle until you can no longer move (twist) the clamped item. Do not over tighten as this may damage item and / or the vise.

Step 7: When finished working on the item, slowly turn screw handle counterclockwise to release the item.

Swivel Base Operation

The vise is generally operated perpendicular to the workbench, enabling work to be performed from either side of the vise. In some cases, the vise may need to be rotated to allow better and safer access to the item. In order to change the position of the vise, please follow the steps below:

Step 1: After item is securely mounted in the vise, slowly loosen each lockdown located on both sides of the vise. Care should be taken not to over-loosen or remove the lockdowns as this may cause the vise to tip over and cause great bodily injury.

Loosen (turn counterclockwise) each lock down about ¼ of a turn until the vise is able to swivel from the base.

Step 2: Swivel the vise to allow better and safer access to the item.

Step 3: Tighten (turn clockwise) each lockdown so that the vise is securely clamped to the base.
