Ok! Now that everything’s dry fitted, and we have a basic setup put on the rig and start making the fine adjustments. I found it easier to have a mirror near by to make sure it’s sitting on the shoulder correctly and things look and feel correct.



Now, for my design, I want to add some shoulder padding, so before I glue anything in place, I want to cut some pipe insulation, creating the 90° angles. Then, hot glue and tape it to hold the form until the glue is secure. And that’s the optional shoulder padding.



Once everything is setup the way you like it, just mark all of your PVC connections, (I like to use 2 lines to assure perfect alignment) and glue it together!



And be sure to number the pieces also!

Trust me, it’s very easy to lose track of what pieces go where and PVC glue cures quickly! You can see in one of the photos, where I forgot to mark my PVC and I glued it together and set it up for the wrong shoulder. So I had to make another one.
