MSC Industrial Supply Co.
This is a story about two tensioners, one fabricated with machine tools and the second fabricated in a garage with a minimum of tools. In fact, the only power tool you will need is a drill motor, yet the finished products will be almost identical.
Your first response to fabricating something may be, “I don’t have the necessary tools; I don’t have any way to get the materials I will need.” If you have a door number so the UPS man can find you, you have everything you need. The materials list at the end of this story contains everything you will need. The rod-end bearings and lock nuts were purchased from AFCO Hot Rod Parts. The aluminum round stock and cutting tools were purchased from MSC.
