Re: vibrating bar supported by light string to reduce damping

[Bernard Cleyet <anngeorg@PACBELL.NET>]

reference?  I thought he'd want the manufacturer or if you are, then how
you made it.

Incidentally for a number of self made apparatuses would not reference
to  Strong's Procedures be appropriate?

bc,  who thinks inability to find a "reference" and JD's Thag et al. are
related.
