Saw these rollers from some type of offset printing press at the scrap yard and of course, I couldn't see them go to waste. Got about ten cylinders, the largest were 12" diameter, 1/2" wall thickness and about 56" long, with geared shafts welded on the end. The printing roller looks like it was chromed.
I have a few ideas for them, a roller for my Bobcat, a tow behind aerator, lawn roller, etc.. Probably not enough to use all of them yet. If you're in the Long Island area you're welcome to some of them if you have a wacky project in mind.
