I don't know what Steve's look like but there are pictures of one in my uploads that I build and it only needs to cost a few dollars for the knobs and bolts. The bolts are just hardware store carriage bolts in 1/4" size (or whatever fits the knobs you get). I don't remember which page in my uploads, at least 4 or 5 back, maybe more. To the right of the pictures in the uploads is the thread link to where they were posted.
