  • Page 2 ATTENTION! Read and understand these instructions COMPLETELY AND THOROUGHLY before starting the installation or cutting into your bench. We highly recommend that you NOT begin installation unless you have ALL vise hardware in your possession. Unpacking your vise: Some parts are heavy. Be careful as you unpack and handle them. Also be aware that although we make every effort to ease all edges, being cast and machined parts you may encounter a sharp egde or burr.
  • Page 3: About These Instructions

    19th century and earlier. Unlike American examples, which use a T- shaped casting and sliding wooden handle, we patterned our vise after extant French examples. The classic look and function pairs excellently with the Benchcrafted Crisscross and maintains our ideal of effortless workholding.
  • Page 4 on a glue line.) The chop can be as narrow as 5”, but you’ll get better holding if you make it around 8” wide at the top. You can cut any design you like onto the sides of the chop--tombstone shape, coves and curves-whatever.
  • Page 5 Tip: when drilling deep holes use a sharp, high quality bit and back the bit out frequently (every 1/2” or so) to clear chips. Drill clear through the leg and chop to make installation easier should you need to tap the pins out from the opposite side.
  • Page 6 3. Check for Toe-in The Crisscross is manufactured with a small amount of toe-in. This ensures that the very top of the chop contacts the front of your bench first. Normally you can acheive this by planing your inside chop face to a taper. But since this feature is built into the Crisscross, you can keep your chop faces parallel.
  • Page 7 Here's a critical step: You need to position the vise’s nut and fasten it to the bench leg so its in line with the movement of the Crisscross. Here's how you do it: Remount the Crisscross and with the flange/screw assembly attached to the chop and passing through the leg, thread the nut onto the screw until it gets close to the back of the leg.
  • Page 8 Next, place a bracket in the mortise and press it tight to the upper end of the mortise (where it butts into end grain) and while holding it tight, use a transfer punch or awl to mark for the two mounting screws. Try to bias the location slightly towards the upper end of the mortise, so as you install the screws the bracket will be drawn tight to the end of the mortise.
  • Page 9 the other arm. With the pivot pin in place, set the chop/ leg upright and test the action of the Crisscross (you might want to clamp the leg to a bench to steady it.) The chop should now “float” in and out quite easily as the Crisscross supports the weight of the chop.
  • Page 10 The Crisscross mortise in the leg requires some different joinery between the leg and front rail in typical Roubo-style workbenches. In the Benchcrafted Split Top Roubo, the typical placement of the mortise and tenon of the front rail, and the bolt and barrel nut falls within the Crisscross mortise. To solve this issue, a thicker front rail (and tenon) is made to allow the bolt and barrel nut to be installed behind the Crisscross mortise.

    handle slides down to the hub when you release it, the mushroom nuts may eventually loosen from this action. Applying some Locktite to the mushroom nut threads will prevent them from loosening. The screw travels 1/2” per revolution. This is twice as fast as typical metal vise screws. Subsequently, you don’t need to crank down on the handle as much as you’d expect to hold your work securely.
