14-1 Bit and Guidebush selection Only the e7-Bush and
5
⁄16" bit that came with Superjig
are required for all Superjig
box joints. Note: Spiral upcut router bits
will cut cleaner than
straight flute. Where metric size bits are available an 8mm straight
or spiral bit may be substituted for the
5
⁄16". Always start test
routing with the e7-Bush set on “5”, the adjustment mid-range.
