The Connexion Hinge is a two-piece takedown system created by Robertson Stykbow.The Connexion is an option

offered on their bows but it is also sold separately for us novice bowyers to install in our own bows! Installation is simple,

quick and requires minimal tools.


The system is only applicable with straight or slightly deflexed riser shapes.

First,do your blank glue-up

and rough-out as usual keeping the centerline marked.Mark the desired location of the center of the hinge 2"

below the shelf.Use the hinge as a template to mark where the "female" portion will be relieved into the handle.
Image

Use a 3/4" sanding drum to make a 3/8" deep trough for the hinge-be sure the trough is 90degrees to the bow handle.
Image

Now use 2 sided tape (with the centerline marked) Image

place the hinge into positionImage

Be sure you have 1/32" to 1/16" for rotational clearance.


Carefully pre-drill 5/32" holes with the hinge in placeImage

On a glass bow (as pictured) remove the hinge

and drill JUST the glass with a 3/16" bit to avoid plintering the glass. You will be able to hear and "feel" when the bit

clears the glass Image

Next attach the hinge with the supertitanium screws supplied. I like to use MT-13 epoxy

in the holes and on the glass surface at this time Image

Clean excess MT-13 with laquer thinner! Image


NOW CUT YOUR BOW IN HALF! Use any means at your disposal as long as the cut is perpendicular-obviously

use caution to avoid the metal hinge! I use a chop sawImage

Next install butt plates.I use 2 pieces of .050 glass

which corresponds to the thickness of the material lost to the saw blade.Use plastic wrap to protect the hinge and

trough from the epoxy.Epoxy the plates in postion with the bow strung to apply pressure during curing.Image

At this point I like to apply "faux" grip overlays to the hinge ends Image

Finish shape the bow Image

A rubber roll on shur-grip covers the hinge cosmetically or you can make a "faux" leather lace-up grip with velcro Image


VIOLA! Note the grip overlays-a nice touch Image

nowadays I use a phenolic piece with the center cut out and glue on "over" the hinge before cutting the bow in 1/2 .(sorry no pic)
It helps with the "feel" of the grip and makes the hinge less palpable-I used to use moldable epoxy (like on TJ's bow).Image

I also use heel overlays now it helps with the overall appearance.

Think I might have to try that!

Just a quick note - Robertson Stykbow is in MONTANA, not Michigan. Common mistake - MT looks like MI sometimes.

Great tips, might try that on a BBO. Question, is it a hindge or can you pull them apart in two pieces?

When the hinge is opened to 90 degrees it comes apart into two pieces
