I am rebuilding a Welte Philharmonic pipe organ roll player.  The stack
for the note relay has both a primary and larger secondary pouch.  This
larger oblong pouch has a wooden button glued to it that supports the
shorting bars for the contact blocks.  The shorting bar is fixed to a
thin springy brass plate (like key contact plates on organ manuals)
that acts as a return spring.  It exerts a fair amount of pressure.

All of the bleed cups, for both the primary and secondary pouches have
rather large bleed holes.  Somewhere between #60 drill size and #65
drill size.  The rail that contains the larger pouches has the bleeds
pressed in a hole as usual,  but I found paper covering the bleeds with
a tiny hole punched through the size of a pin.

Back in July, 2002, in a discussion on bleed hole sizes, Richard Vance
posted about bleed holes size #71 as the correct size for the tiny
holes in pipe organ rolls, which makes sense to me.

I'm wondering if the paper covering over the bleed cups, with the
smaller hole punched through was done at some later time rather than at
the factory for why should they install the larger size bleeds, only to
cover them up and punch smaller holes.

Should I just leave out the bleed cups and paper over the holes and
punch through a #71 hole, or even close the holes on the cups and
re-drill like Vance suggests and eliminate the paper?

Input would be most welcome.

Thanks
Dave Krall
