[SergentEng] Made your own coupler boxes?

Dale Buxton
 

Tim,
I use one of two solutions. One, is to use the bottom half of a Kadee 714 coupler box. This half has the Kadee pivot pin with the screw hole in it. It is the same(ish) general diameter as the Sergent pivot hole. The other is to use a very short length of 3/32 brass tube as the pivot. I put a 2-56 washer on top of this and use a 1.4mm Phillips head screw to hold the whole shabang together. Either solution might require that you slightly ream the Sargent's pivot hole.

Apologies if this comes through twice, I sent the
original message some 13 odd hours ago and Yahoo still
hasn't delivered it. Why am I not
surprised!

A question for
all of you who have made your own coupler boxes to put
Sergents in; what have you used
for the
pivot? I am about to make new coupler boxes to replace the
incredibly lame ones on a model.

I have 
designed all the parts I need to make and that just leaves
me with the 
pivot. All I can think of is
some 1/8"
Plastruct tube though I wonder 
how well it would wear.

Thanks to those that replied. It looks like I'll be going the brass tube path; 1/8" tube has an ID that's almost
the right size for an M3 screw so I might be able to tap the tube and not the floor of the model should I wish to.
