Frame Of Hydraulic Press Made Out Of Old Bullzdozer Parts
Eric Webster, Lansdowne, Ontario: "I made the frame of this hydraulic press out of old bulldozer parts. It runs off tractor hydraulics and has a ębed' made out of a 6-in. wide, 3/4-in thick steel plate. The 6-in. dia. hydraulic cylinder is off an overhead loader and has a 3-ft. stroke so it can develop a tremendous amount of pressure, applying up to 45 tons when used with a newer tractor equipped with a 3,000-lb. pump. Using the tractor's variable flow hydraulics I can slow the press down so much that I can barely see it move. Because of the slow speed it works great for straightening out objects. It can easily bend a 3/4-in. thick piece of metal at a right angle. We have different attachments to fit the shaft. One time we used this press to take a 90 degree bend out of a 4-ft. long hydraulic cylinder shaft.
  "I made this tire band saw out of two spare car tires. An electric motor belt-drives a pair of pulleys that turn a shaft that rotates the bottom tire. The saw blade runs from one tire to the other. My only expense was for the blade and the guide.
  "My homemade 48-in. belt sander is operated by a 1 hp electric motor. I use it to make furniture. The belt is 6 in. wide. A pair of screws at each end of the unit are used to adjust the belt and keep it running true."
