There are probably quite a few of these floating around. I got the idea from one of these sites years ago and finally decided to make one this week. It's 1-1/4" PVC. I wish I had done 1" PVC with a 2" arrow tube but I had a bunch of this stuff lying around. It works pretty well. The paint is kinda iffy. It scratches easily. The pipe insulation made a huge difference with how the bow sits. It kept falling over until I put the insulation on.
