What Router Do I use?
Can I use my router with Leigh jigs and attachments? Most likely. We recommend a minimum of 1.5 HP (9-10 amps). A plunge router is also recommended for Isoloc templates and is a must for the M2 but is not required for the D4 and F1.
Why does Leigh use guidebushes instead of bearings? Conventional guides are much more versatile than shank mounted bearings. Bearings severely limit the range of board thicknesses, joint sizes and pin and tail spacing on joinery jigs.
Do I need to use Leigh’s guidebushes? The router industry isn't standardized, so you may need to use Leigh's template guidebush and mounting adaptor system (GBS) to match your router to Leigh Jigs and Attachments. Note: The Leigh 711TP and 716TP are universal style template guidebushes with nuts. Many routers accept these guides directly or come with an adaptor made to fit them.
Note: Some template guide bushings have very short barrels and are not recommended for the D1600 and D4R dovetail jigs. The barrel length on Leigh template guide bushings is .265” (just over ¼”). Shorter barrels or barrels that are recessed in the router base may cause the router bit to come in contact with the finger bar.
GBS Guidebush System (colored pink). The GBS is required for the D4
Dovetail Jig and the M2 Multiple Mortise & Tenon Attachment. Use the instructions
below and the chart on the facing page to select the right component(s) for your router. Note:
The GBS does not work on the F1 Finger or Isoloc Joint Templates.
VGS Variable Guidebush System (colored green). The VGS is included with
the F1 Finger Joint Template and the I1 Isoloc Joint Templates, but you may need an
adaptor for your router (see below). Note: The VGS does not work on the D4 or the M2.
