Repairing Cracked Chime Tubes
By David Dewey

Hoping the wide knowledge base of this group can help me out.  Our
church organ has a set of 21 Maas chimes, electric action.  They
are brushed brass finish, with black plastic caps (what the striker
hits, actually).

Two notes do not ring clear (numbers 18 & 19, D and D#) and I thought
the problem was in the strikers or dampers.  Well, nope -- close
inspection reveals a crack a few inches long at the tops of the tubes.
Is it possible to take these apart and silver solder or braze the
cracks to restore the clear chime sound?

 [ At 
 [ is an article that describes how to repair the chimes using a TIG
 [ (Tungsten Inert Gas) welder and silicon bronze rod.  "A possible
 [ cause of cracking could be found in the way the tubes are formed
 [ during manufacture.  The better grades of [Deagan] chimes -- Class A,
 [ B and C -- were drawn, but the Class R tubes were rolled from a brass
 [ sheet, shaped into a tube and joined at a seam."
