I haven't found a shop dolly that can handle my yamaha very well, so I decided to buld my own. It is made from 1 1/4 steel pipe, and 1 1/4 angle iron. The wheels are rated at 2500lbs each, and supported with 3/16 steel. The handle is 1" steel. I plan on carpeting the lift pad to protect the bottom of the sleds, and painting the whole thing, but it's only about 25 degrees in my garage, so the paint won't cure too well. It works very well, with no flex in the frame at all, unlike the dollies that srtaddle the snowmobile.
