Ok, I always wanted one and after seeing what's online here with the step by steps and how too's and working with friends who have some, I desided to make one. I'm posting here and request input, please.
I got the backpack and PVC, I still need an ajustable lap seat belt for the backpack. This is the easy part. I'm looking at around 10 foot tall. Pics below.

My main plan is to make it lightweight. I found a lightweight skull at an online halloween store (pic below). I,m doing eyebrows out of dryer lint clay to make it look more evil. I'll paint or stain it.

I found some thin hard plastic to form the shoulders and chest and then I'll cover it with 1" foam. I used zip ties.

Somebody PMed me asking if that’s me in the picture with the skull above, No it’s not me. Go to this web site.

I had some issues with the skull. It’s hollow and filled with tiny Styrofoam beads. So when I drilled the bottom of the skull to insert the ¾” PVC, all the beads came out. I drilled small holes all over the top of the ¾ PVC that goes into the skull and filled the skull with spray foam from home depot, solid as a rock and very light weight.
The PVC for the frame is 1” and the ¾” PVC from the skull fits through the 1” T. I'm done with the eyebrows and painting. Working on the red LED eyes and mouth.
I clamped a small round piece of wood on the ¾ as a stop.

I love the eyebrow area modifications. It does make it look much more menacing!

Looking Scary! Can't wait to see the finished work!

Got it together. Had to shorten the upper arms and covered the chest with thin black fabric to tone down the white plastic and foam. Had to make a stand for it with some wood I had laying around. It stands a little under 10 feet.
