Online Extra multi-function vise Handscrew Mount As a stand-alone project, the swivel vise from Woodsmith No. 219 is an incredibly useful shop accessory. But you can give the vise even more versatility by building a couple additional clamping fixtures. The first fixture (shown at right) is a mount for a standard 10" handscrew. QUICK CONSTRUCTION. Start by cutting the base and two brackets to size. To match the look of the vise, I chamfered the edges a. FRONT of these parts, as shown in the drawings at right. There VIEW are a couple of options when it comes to marking the Hand- !/2 45° holes in the base for the pipe flange. You can use the pipe screw 1 flange from the machinist’s vise mount and move it each Bracket time you switch between fixtures. Or, the option I chose was to purchase an extra flange and leave it attached to 1!/2 the base. This makes it easy to switch between clamping fixtures by unscrewing the flange from the hitch ball. 1 Base DRILL HOLES & ASSEMBLE. With the flange location marked, drill the holes in the base. You’ll then drill the counterbores for the T-nuts and tap them in place with a hammer. Next, I attached the b. brackets to the base with some screws and held one leg of the handscrew between the brackets 10" handscrew &/8 to mark and drill the through holes for T-nut the bolts (detail ‘a’).

B Online Extra Bar Clamp Mount Having built two mounts for my swivel vise (one for a machin- ist’s vise and one for a handscrew), I still felt the need to add one more fixture. That third fixture is the bar clamp mount you see at right. This mount holds two bar clamps in a couple of cradles and adds even more functionality to my swivel vise. FAMILIAR CONSTRUCTION. You’ll notice right away that the base for the bar clamp mount is very similar to the base for the hand- screw mount, just a little longer. This is a good place to start. Cut the base to size and chamfer the edges. You’ll also lay out the holes to mount the pipe flange as before. Now, drill these through holes and the counterbores for the T-nuts (detail ‘a’). b. Tap the T-nuts in place with a hammer. !/8 1!/4 CRADLE BLOCKS. The cradle blocks are next. They hold the bar clamps in an upright posi- 3 tion. Glue up a couple of pieces of ⁄4"-thick stock, plane them to final thickness, and then B cut them to size. I used a dado blade in my table saw to cut the slots for the bar clamps. TOP VIEW Most bar clamps have a similar design, but be sure to have the clamps that you’ll be using A on hand in order to size the slots. Now, chamfer the edges of the blocks (drawing at right 4!/8 and detail ‘a’) and attach them to the base with glue.
