Here we go with yet another bicycle repair stand. Most of the ideas here have been done before, and posted on the web. For example, using a weight bench as the stand base has been done. As you would expect, a weight bench makes a good, stable base.
I have just a couple ideas to add; here they are: 1) I used vice-grips for the bike frame clamps; 2) I made a front wheel guide to keep the front wheel in line. That's pretty much it. The pictures tell the story.
