Attaching Ribs & Spikes

I attached the ribs using the black duct tape. I spaced them about 8" apart.

For the spikes I cut small lengths of the irrigation tube, drilled a small hole, inserted the tube at an angle, and added more duct tape.

On the back of the head I had the pipe turn up, then back again. After cutting a hole into the spine this provided a good connection for spine to head.
