Inspection of hexagons over weekend (they were stored for couple of years at friend's place, they are now in Ballarat, in the room next to future observatory).

The glue I used for joining struts ("liquid nails") is rubbish.. couple of struts felled off, so yesterday I applied screws to hold them back together on all 14 hexagons.

At the end this will not be a serious problem, as my intention was always to final assemble the whole structure together by means of screws and perforated steel tape (still searching for 20mm wide, 0.5~0.75mm variety... ).

And still waiting for ring to be welded together...

Hi Bojan

I'm building a truncated trapezium, using ply panels and perforated strap joints/screwed, as well as epoxy infill. I intend to use Pryda Speed Brace which is 25mm x 0.8mm in either 6 or 15 metre rolls. (SB082/6, Also known as hoop iron in this size). Pryda has a good catalogue available online.

Regards, Rod
