Hi List,
Several months ago, there was some discussion on step keys. I have a pulley
with a 1/4" grove and the engine shaft is 3/8" wide. The distance between
the top of the pulley grove and the bottom of the shaft grove is 1/4". My
local supplier told me that step keys don't come in double steps. That is the
3/8" will step down to 5/16" and the 5/16" will step down to 1/4".
Since I couldn't obtain a key that went from 3/8" to 1/4". I made one. I
took a piece of 1/4" square key and silver soldered two strips of 1/16" x 1/8"
metal on both sides. I cleaned up (with a file) the modified key. Then, I
used the modified key to install the pulley (with a set screw) on the engine
shaft.
