recently i was asked to figure out a way to mount
under table hinges and stops
for a series of square tables to round folded wings (4 each)

.
when the wings were folded up
they had to lay flat to the underside flush
with the table top
(no room for crumbs or crud to gather)
so had to be inset to both
here is the generic jig i came up with
with the top and wings upside down
and a business card in between them
for spacing i cut out the hinge profile (twice)
and registered the jig to the corners of the top
with stops to hold the wings in place
(under the jig side showing
corner stops with curved ends for the round wings
to register too)

.
i always use a 1/2”x1/2” long patterning bit
as the offsets for the bushings are to much trouble to get right
and make a direct profile cutout
(start in the field so as not to gouge the edges of the jig)
for depth of cut lay the hinge and jig
with the hinge under the router base
and drop the router to the surface of the top
and lock that depth then remove the hinge
and route

.
then another jig for the knuckle too
this one to each side separated
so i can just come in from the side


.
now for the metal ‘holder-open-stops’
(i didn’t design these
the parts were given to me)
it is a series of 3 parts
and 4 routs
this is the ‘master’ jig for that
it has stops under for the top and the wings
the innovation is the ‘cut out’ to accept 4 different profile inserts
all registered to the center line
and all for different width , depth , and length routs
this is the actual metal bar
that holds the wing up
it is deeper and has a finger hole
and corresponding finger slot deeper still



.
here is the flush metal plate to hold the ‘slider’
screwed to the table top
and a 1/32” ‘rub plate’ clued to the wing
it is 1/8”wider than the ‘slider’

.
the whole point of this blog
is to show how 1 master jig
can be used with inserts to
make many different routs
that can be re-used and adapted to the same jig
instead of making all dedicated masters
for all the different routs
here are some of the inserts


.
and here is the one with an insert in it
that made the slider rout
and the finger rout too

.
well this has been a ‘woodworki-leaks’
i was asked to keep this a secret
as it is ‘proprietary’ to some secret project
(there are no pictures still available
of the actual finished tables
these pictures were taken
with a spy camera
and smuggled out)
but as i was given no instructions on how to do this work
and nobody even looked at how i did it
or asked how the jig worked
i feel that i designed it myself

now i have to go and catch my plane
to sweden (i hope to get a ‘message’)
before i get extradited
back to the states
to stand trial for divulging
this information

merry christmas !

I, for one, am glad you leaked it.
And I hope the hackers don’t take down your server.

Nice pictorial. You do such clever work.

Very clean work and nicely done.
Have a Very Merry Christmas!

p.s. do you have any snow there? I was hoping for some here. Guess we’ll have to drive into the mountains Christmas morning to play in the snow!

Very neat David! Great planning and execution, as always.
And, here I thought all the great woodworkers were in Santa Rosa! :-)

Lumberjocks leaking, well David now I have heard everything. It looks like a good solid solution and nicely done with the jigs. I have to agree with you that guide collars are fussy. I tried to use a guide collar on the project I just finished today and after a 3 failed tries I went and bought a pattern bit which did the job. I appreciate your comment on this, as now I know I’m not the only one who has had an issue with guide collars. Thank you and a very Merry Christmas to you too.
