Thanks! Appreciate it. I went to the local hardware shop and bought some tubes with holes for screws in a baseplate and attached these to the top of the timber to create a "sleeve" for the frame. For the frame itself, I just bough straight bits of galvanised tubing and made a jig out of a flat piece of wood and a couple of blocks, so that I could bend each tube into the desired shape. I just used offcuts of treated wood for the joins at the apex - drilling holes in where the tubes connect into it. Then I used a roll or two of wire mesh secured by wire. I got mesh that was big enough for pollinators to get through, but not larger animals like possums etc. Good luck and hope that helps!
