Air Test Table video

[ronhob]

For those of you that want to build a fairly inexpensive air test table, here you go. You may want to check that the center dowel fits snugly into the tee while you are getting the other supplies. My dowel is cut at 31 and a 1/2 inches, but I would wait to cut yours till you have the rest of it put together and re-measure. You could also skip the threaded parts on the pendulum, and just get couplers if you want. I was originally going to glue everything, so I wanted to be able to take the pendulum loose, so I did the threaded parts. Couplers would be faster, less expensive, and still prove effective. The center cross is the one fitting that doesn't work well without some modification. I spent a while sanding the inside of it to get it to swing freely. I'm sure some of you will find a better solution for that.

Your table is actually the one that inspired me to make one!
