Some router bits may be to long to use with the extension, requiring spacing the router.
1. Determine the thickness of spacer
you may require generally from 3/8" to 3/4"
2. Prepair a plywood or particle board blank
slightly larger than the base of the router
3. Use the original subbase or paper
template available on this website onto
the blank and mark outside, inside
the mounting hole locations and lift
access hole if applicable.
4. Cut center hole using jig saw or scroll saw.
Drill all mounting holes.
Trimming outer edge to match the routers
base is personal preference but not necessary.
5. Using longer bolts, place spacer between
router and insert plate or router table top
and secure with bolts.
6. A plywood or particle board subtop may
also be used
