Yes, the eight points where the hoops meet are screwed in place using a 1 inch screw. Irish recommended that for added support. When I switch to the black plastic tubing I'll end use a larger screw, perhaps a 1 1/4 so that I know it makes it thru 3 of the 4 pipe walls.
Another change I'll make with the next models...
There is room to move where the tubes go into the PVC crosses. I'm going to buildup the last inch of each piece with perhaps electrical tape before I wrap the rope on. I'm not set on electrical tape but I will use something so that the rope is a snugger fit into the PVC.
I've got some other small adjustments to make the the structure to make me happier...Let's call this the customizing stage.
