After building the model myself, I have found tab and slot construction
rather tricky for students. I do not cut slots, I bend the tabs
and glue them to the marks for the slots. Where small tabs are to
go through slots in a larger tab, I cut off the small tabs and glue the
large one.
On the secondary mirror support, it is necessary leave white tabs on
the ends of the black arms. These bend down and glue to the
outside of the insert tube, with the black showing.
In
place of dowel, I find skewers from the supermarket work well.
