Doesn't seem to have worked, but I was able to right click and copy the URLs from the photo ghosts in this post and then paste into a new window and get the image. This is just PVC pipe, chosen to fit my top tube as close as possible. Band saw the top of a Tee fitting off and line it with old inner tubes, hose clamp it back together around the top tube. I reduced from 1.5" around the top tube to 1" for the rest. 1.5" tube was bulky for the whole thing. Length of pipe, Tee, short pipes, Tees, short pipes, elbows, short pipes. That should create a "square" of pipes on top of a pipe that fits into the modified Tee on the top tube of the bike.
I have the water bottle cages on there as this rig will prevent you from reaching the typical location.
The pad is a "neck pillow" wrapped with the self clinging stretchy tape that is sold alongside Ace Bandages. Depending on the height one makes it, it wouldn't support one's full weight leaning on it. I use it mostly to get my torso down, shoulders down, elbows bent. I don't lean on it heavily. It's almost more of a reminder to have proper posture and get the upper body weight off the wrists.
I used to use a strap, from the top Tee to the seat tube/seat stays to add support strength, but that really gets in the way of straddling the bike when stopped.
As I said before, this is what I use, and anyone as stupid as me to use it assumes their own risks. If it breaks and causes one to face plant, that's their own set of problems.
Oh, one last thing, it makes your chest hot on a warm day...
