This was all about setting the proper distance of the support holes on the tubes. The sound of the chime depends on getting this distance presise.
Since I don’t own a drill press, a little extra work had to go into figuring out how to drill the two support holes exactly opposite of each other.
Again, much credit for dealing with the support holes properly goes to Lee Hite and his web site on chimes.
I tested the chimes informally at the end. I will actually test the tuning and work on the support structure on part four next Friday.
