The Binding Router Jig is the best system available for routing binding and purfling trenches in guitars and other instruments. The jig holds the instrument so the sides are perfectly vertical and in line with the router bit. This guarantees perfectly square, perfectly even binding rebates every time. The benefits are more consistent bindings and less work levelling up the bindings after installation. - Smooth, precise & consistent - Precision machined & cast - Solid aluminium & steel construction - Includes instructions for assembly & use Details Steady aluminum router support post with carriage Sliding support brackets (4), adjustable for body shapes and heights Every part in the first main photo is included!
