[SEL] Key Installation

[FRM8198 at aol.com]

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.
