JIG ASSEMBLY, MOUNTING, & USING THE CLAMPS

Chapter 1Super Jig-12-18-24 User Guide

1-19 The Jig Clamps Use a piece of flat, even-thickness wood

to familiarize yourself with the jig cam clamps.

You will operate

the cam-action speed clamps every time you use the jig, so get

used to the feel of the clamps first. Do not force the cam-action

speed-clamp. It has great leverage, and excessive force may damage

the workpiece or the jig.

1-20 A smooth, firm action is enough to engage the clamp.

Rule of thumb: If you can't throw the lever by pressing the end

of it firmly with your thumb, reduce the tension. Firm thumb

pressure is about right. A few minutes of trial and error will help

you feel the right clamp tension.

1-21 For all but the wider workpieces, you need only operate the

clamp on the workpiece end of the jig to release the board



. For

narrower boards, the clamp at the free end



should be just tight

enough to bow the clamp bar about

⁄16"[2mm]



1-22 When engaged, the front clamp levers should normally point

down and the rear levers should point away from the operator



or up to 90˚ either side



as required to obtain the optimum

clamping pressure.

1-23 To gain height for a more comfortable working position

or for routing longer boards, mount the jig to a box that can be

bolted securely to a bench.
