Holy crap did you see how much one of those things costs????
$93 plus shipping! That's insanely overpriced. And the smallest they go is 2", and that is too much.
I bought a block of wood at the hardware store yesterday for $2.97. Now all it takes is to dig up a few bolts and apply elbow grease. Thanks for reminding me about this YZ. It has given me something productive to do. I'll keep you updated on my progress.
I think the photo of the fellow in the boat is funny! He's obviously (judging by the name of his vessel) a self-aware man. Nothing wrong with that. Just.... don't lean back any further.
