notes sharing stems

[James Wilkinson]

\version 2.13.34

I've got three percussion voices sharing a staff. When I made the 
bottom two voices be \voiceTwo and \voiceFour, I got downward stems, 
but each note had its own stem. Then I tried making them both be 
\voiceTwo. That gave me the printed output that I wanted: when notes 
coincide, they share a stem. However, I got lots of "ignoring too 
many colliding note columns" warnings.

Warnings make me nervous. I'm considering putting both those parts in 
a single voice and writing chords when notes coincide.

Anybody have a better suggestion?

thanks

If there is one word to describe me, that word would have to be 
"profectionist".
Any form of incompitence is an athema to me.
Metathesis??? Don't ax me.
Just between you and I, the grammar used by Americans are getting worse.
I can only help but wonder what the cause of this might be.
It just ceases to amaze me how it could be the case, but mostly I 
could care less.
