Hi All, David Dewey sent me some pictures of a Baldwin air motor
he's rebuilding. They clearly show that Baldwin used a piece of paper
between the bellows and the manifold.
As David put it, "One of the cleanest take-a-parts I've done! Put
the motor body on a solid bench, used a block of steel the size of the
pneumatic edge and a quick hammer blow broke the glue bond, then I had
to lift the pneumatics off the nails. It was when I was scraping the
paper off that I noticed the printing stayed put!"
Although I can't remember the names of some other air motors offhand,
this isn't the first time I've seen paper or thin cardboard used
between the bellows and the place they get mounted. But in every case
where there was a paper-type gasket, the bellows were relatively easy
to remove and there wasn't any damage to the bellows or the block.
This got me to thinking; Should this be a rebuilding technique or
methodology we should be using all of the time? What are your thoughts?
