I am going to cut a bicycle frame in two.
The frame has a spar main section of a taller-vertically rectangle with
half-rounds on the top and bottom; this is place for the cut. I'll make
a matching inner sleeve for both alignment and tightening.
There is a vertically-coplanar tube joining this spar at an angle of
about 20 degrees. I will run a rod though this tube and it will cross the
joint into the sleeve holding a captive nut.
Does the angle of the cut matter - 90 to the spar, 90 to the rod, half-
I have a bit of latitude with lateral placement of the cut, so I could
arrange for the rod to cross the joint other than centred. The weight
would tend to open the bottom of the joint first, would a lower crossing
