The tracker bar cardboard honeycomb can be very tricky to construct if your
fingers are not as flexible as they once were. I describe my method
The drilled tracker bar is marked out and positioned face down on a thick
layer of BlueTack as shown in photo .

Wooden dowels are then cut to be long enough to push through the holes and
into the BlueTack (Tesco bamboo skewers did the business for me).
The dowels should be long enough to enable them to be pulled out before the
glue on the honeycomb has dried. The dowels provide support for the cardboard
sections as they are glued into place. They also enable all cardboard
sections to be dry assembled to check for correct length and height.

Warning: The bamboo skewers will swell when the wet glue gets
on them, so remove the dowels as you progress along the tracker bar.
