A.B.Chase Upright?????

[Joseph Garrett]

A few days ago, I posted a request for information on the trapwork of an
A.B. Chase Upright. Haven't seen one response. Please, guys and gals check
out your data bases and see if'n you have one in your client base. All I
need is a drawing or a photo of the trapwork layout. The one I have to fix
is missing all of the lower trapwork except the wood blocks/pivots and the
pedals themselves. The vertical actuator rods are still there,so I have a
little bit of an idea how it all was set up. BUT, two of the horizontal bars
appear to cross over and I'd like to do a neat job of remanufacturing them.
Also there is some kind of spring system for each of the three horizontal
bars. I have no clue how the bars and the springs interact. Any help will be
VERY appreciated!!
Best Regards,
