Please take a look and see if you can help me figure out how to make this thing. The diagram is eschpecially illuminating.
THE
DIE-CAST DROP-FORGED PLASTIC
TRICHOTOMETRIC
INDICATOR-SUPPORT
Inquiries concerning the mounting of
the Trichotometric Indicator
Support indicate that some difficulty
is being experienced with the
brackets which attach the support. As
an aid toward fabricating the
support brackets, the accompanying
illustration is provided to show
the type of material as well as the
dimensional data needed. It will
be noted that in attaching the bracket
to the support a special ambi-
melical hexnut is used. The
application of this nut is unique in that
any attempt to remove it in the
conventional manner only tightens it.
Because of this design, the nut must
be fully screwed on before it can
be screwed off.

How about welding 3 screws on a back-plate?
ReplyDeleteAlternatively you could drill 3 holes in a back-plate and secure the bolts with a nut.
It's one of those.
ReplyDeleteSince the piece with three threaded ends can't exist, there's no way you can actually do anything with it.
It only seems to have three ends, until you look at the other end.
I admit this is fancier than when I've seen it before, since the bracket is also an illusion.
I'm not sure if the point of this post is to see what people don't see, or see who notices the truth first. Hence I'm not waiting.

OK, so the bracket and the nuts are Moibus strups and the attachment is Escheresque....
