Aeolian Primary Valves Have No Bleeds
By Donald Barton
I am in the process of restoring a 1905 Aeolian Themodist double valve
action. The primary valves have no bleeds. The secondary valves have
what I consider very large bleeds -- just shy of 3/32".
Is anyone familiar with this action who might have a theory of the
purpose of such a large bleeds? Should they be replaced with a more
standard bleed? Any advice would be appreciated.
