Measure twice, order once

It turns out that 3/4" electrical conduit does not in fact have a 7/8 " outside diameter. I know this because it completely does not fit in the nice new 7/8" bearings that I received yesterday. Fortunately I scoured the house and found a mic stand that has 7/8" outside diameter tubing as its base, so I am now down one mic stand but up one set of crank raw materials. At the end of this week I hope to have a crank welded together.
