Hi all,  I work for a Steinway piano technician in Worcester,
Massachusetts, and he has about a dozen or so baby grand pianos
stored on their sides without any problems.  Some are still waiting
to be restored or repaired.  He said to me that it doesn't harm
the piano whatsoever.

As for my band organ project, it's coming along slowly but building
the pipes are going okay.  I had to remake one tiny pipe <lol> but
other than that, it's going swimmingly! I'll post pictures as I go
along.

Sincerely, Jeff Bridges
