Measuring Fixture 2
15-Aug-2006
One of the keyways in the wheels was known to be off
by about 1 degree. I needed to know the exact angular offset, and I had
to assure myself that the other wheels were correct. I made a measuring
fixture. The first step was to make a plug for the rotary table. The
smaller diameter was a close slip fit in the table and the larger was
an even closer slip fit in the wheel bore. Here I'm cutting the keyway
in the plug to match the wheel.
