Fit the holder to the router first. Before fit-
ting a variable bush to a holder, fit one of
the small nylon thread-inserts to the hole
in the side of the thread. Leave the insert
on its “tree” and push into the hole. Then
snap off the “tree”. Once threaded into a
holder, the insert will become trapped and
should not fall out when removed. However,
wrap some scotch tape around the bush to
prevent this. The four inserts and two spares
will last a long time.

When you have the best joint fit, mark the
bush and holder with permanent ink for
future reference. Use the same cutter next
time.
