Hi John And Carolyn,

Yes, I received my double wall, hubs only, w/stainless zip ties. All is well!

I have spray painted all the hubs and inner hubs with Krylon, to help with UV protection. It takes 9 cans. I have cut all of my struts from schedule 80 grey PVC, and drilled them. That took a total of four days, and determination, working alone.

That's my hand drill, drill-press. I built a little jig out of cedar and learned to eyeball when the first hole was centered, while drilling the other end.

I have an oak tree to fell before I build the 23.9', (had to calculate for the flange on the ends of the PVC conduit to get two pieces out of each ten footer. It took 83, 10' pieces), double wall greenhouse. The tree also shades our garden in the afternoon and I have put it off, because it's a nice healthy oak and the birds use it a lot. I'll plant some dwarf trees to replace it...sorta. It's been raining a lot here, so I've had a good excuse for not dropping it.

I've been wanting to build a Bucky dome since high school so I'm motivated!

Know of anyone making a dome shaped covering?

You know, you can cover one of these with plastic, add some rebar wire mesh, spray with foam and then concrete, wait til it sets, then take down your dome and do it again? Use it like a form!

I plan to add a little heated fan, blowing between the walls of the double wall dome. Hopefully, I can extend our growing season with this. I'm thinking of burying some pex tubing under the ground, as well, for in floor heat.

I'll send more pictures when I get them. I'm a big fan of ZipTie Domes! I'm a promoter, Dudes! I'm telling everyone about your clever product!
