Routing a perfect insert rebate.

Can anyone offer advice to the best way to make a perfect inside cut from
and outside template? Specifically, how to make a perfect hole to recieve a
router table insert.

All I can think of is using a small guide bushing to make a secondary
template with a bigger hole than the insert (or I guess I could just use a
trimmer/template follower), and then a bigger bushing to make the final hole
exactly the right size for the original insert.

I guess this would work OK but it sounds elaborate. Is there a better way?

Regards

I recently made mine table top with a circular insert. To make the
table top hole, I make a template with 1/4 plywood that fit the insert
and use the template and pattern bit to route the hole on the table
top. The thin plywood allow you to test and adjust the fit by hand
sanding.

He needs to cut the hole for the insert, not make another insert.

I'm lurking because I need to do the same, moving my drill press sanding
drum table to a new, bigger DP.

You've got the right idea. Rout a female from the male, small collar to bit
distance. Use female with greater collar to bit distance to make the
opening.

Measure the inside diameter of the hole in your router table. Then use
a circle-cutting jig for the router to cut a hole of the size you
want.

If you have a template guide for your router base, the circle jig is
easy to make -- or you can buy one.

Set the router bit depth by placing the table insert across two of the
pieces of timber. Then place your router on top of the insert (which
is on top of the timber) and set the bit depth to just touch the table
top. This will set the router depth to be exactly the thickness of
insert plus the templates and the resulting routing to be exactly the
depth of the insert.

Your all missing something, When you use the insert to make the female hole
at some point towards the end of the cut the peice falls out creating an
imperfect hole, the entire concept is correct if he has drawer full of
bearing, collars and feelers etc.etc.
Quite an elaborate undertaking for a little insert.

Put your router table insert on your router table in the position you want it
to be.
Using double sided tape fix 4 pieces of timber, MDF, etc (wide enough to
support the router - about 4") tightly around the insert. The length of the
timber should be the length of your insert plus about 4", thickness depends on
length of the router bit you are going to use.
Butt the end of one piece against the side of the other piece.
Remove the router insert.
You have now created an inside template.
Using a 1/2" straight bit with a top bearing the same size as the bit, rout
out the hole to the depth of the insert.
Change to a larger bearing or use a template guide bush or jigsaw/sabre saw to
remove the rest of the waste material.
Perfect fit.

How about stacking the old insert and the new insert and running a straight
bit with a roller?

I would use a template bit (i.e bearing on top) to make a template with
a hole bigger than the insert, then use a bushing to offset a straight
bit by the width of the template bit to create the desired hole.

Depending on the size you are looking doe try a hole saw and then a spindle
sander

What if you used the template you have and make another "inside" template
from it. Then using the new template use a straight trim bit with an
oversize bearing. eg if you use a 1/4" bit to cut the new template the new
template is going to be 1/2" to big. Use a 1/4" trim bit with a 1/2" guide
bearing to make the final. Does this make any sense?
