here is a Tube cutting trick I saw in a 1974 copy of Sport Aviation. Just thought I would pass it along.

EAA member Ralph King of Silver Springs, Florida,
who is building a FOO-Fighter, passed on this clever
gadget for marking tube angles for cutting. Those who
have tried to cut and fit tubing know that it is otherwise a
trial and error exercise at best.
The item in simple terms, is a length of elastic which
is sewn over a backing material length-wise every 1/8".
Wires or small welding rod is inserted between each sewn
strip. After all the wires are inserted into the elastic,
it is wrapped around a piece of the tubing to be fitted.
Use a rubber band to hold the marking device together.
The next step is to push this item up so that the individual
wires contact the structure to be fitted. After all
the wires are pushed into contact, slide the whole marking
gadget back. Draw a pencil line around the contour formed
by the wire tips. Use a silver pencil so that the line can
be seen.
Cut and file the end down to the line. The fit will
please you.
