Re: arsclist cylinder housing design

[David Seubert <seubert@xxxxxxxxxxxxxxxx>]

I've heard of that design. My understanding of the problems with this
design (all hearsay) was that the conical supports ended up putting
pressure on the cylinders and splitting them. Maybe somebody can confirm
this?

I don't have a picture of it, but I had made a sketch of it for a pamphlet I put together, but can't find.  It might be in one of the ARSC Journals or bulletins from around 1972.  He presented it at one of the Indiana University conferences.  It was a square box, but he had an insert triangular shape [pyramid] engineered to fit into both ends to keep the cylinder straight and somewhat away from the sides of the box.  It was quite a unique engineered job, but I don't think they were ever made commercially...only for the Library of Congress.
