Easy Fix

Go to Ray's Outdoors (theres one in Geelong), buy a set of replacement poles for a dome tent, 9.5mm diameter, I think around $10.00. Go to a stainless supplier (Geelong Stainless) and buy a bit of tube that you can get said poles to fit into. Squash one end in a vice after fitting a glass tube part way in, drill a hole for the pivot, cut tube to length, wack another bit of stainless on the other end, 3/16" x 3/4" metal threads epoxy them in for pins (make sure they go into the glass tube) and your done. Have done myself and for about $25-30, you've got enough gear to make 2 sets (cause the replacement tent poles come in packs of 4)
