I converted an old engine stand into this lift that can be used for a variety of things. Right now it has a shaft with a bearing and angle crosspiece to accept frames. This setup allows me to access the frame 360'. I used a rodless pneumatic cylinder controlled by a regulator and two dump ball valves, one to control the input flow and the other to control the exhaust. Very handy.lift.JPGlift1.JPGliftshaft.JPG
