I want to build a dead weight pulling sled and am looking for some plans or a couple of good photos of a sled to get me started. Dimensions and materials used to build a sled and how you operate one of your pulls would also be appreciated. I have seen some sleds on the forum, but wanted a little more detail. If someone is interested in selling a sled, let me know, perhaps we could come to terms. (Penna, Va, Md, West Va, Ohio area prefered) Thanks for any input.
