The 1/2" PVC is not strong enough for climbing. The megahubs are strong enough, but for insurance and liability purposes, we aren’t going to advertise ...

There’s a certain logic to this, but if you’re building a dome of 8’ radius or greater, you’re going to get to a point where you have to lift up the base to...

The research I’ve seen suggests the optimum temperature range of PVC pipe is 0 degrees F to 140F. Above 140 F, you start to see deformation based on softeni...

By the straight math, the angles don’t work. However, depending on the size of the 1V dome you’re building, you might get away with it because of the inhere...

The 1 ½” goes around the hub like a sleeve, and the 1” goes inside the hub arm. They’re dual purpose.  The hubs are designed for Schedule 40 specifications.

The domes are scalable. We have some standard sizes listed with every configuration, but within reason, you can make the domes any diameter you want. The he...

We use pan head bolts, because they’re tapered and they fit right into the molded holes in the hubs.

The mathematical angles actually vary according to the frequency and according to whether it is a 4, 5, or 6-star hub.  The tops of the hubs are flat, but ...

The hubs were designed to be used with Schedule 40 PVC pipe, but we know that lots of people have used different materials for struts.  The important consid...

For the Mega Domes, we are aware of many people using poly-carbonate panels, screwed right into the struts and/or hubs.  Glass would be a little tricky, unl...
