I am finding just about everything I need at C.R Lawrence...( A Window
Glazers Supply Chain ) and McMaster Carr...They are both a tremendous
resource for building a Mammoth Camera....
As a example I could not find a extruded aluminum profile with the
needed specs to make the dark slide Track for a film holder ... The track
has to be fairly close tolerance so that no light leaks will occur... , so
all I am going to do is to couple two aluminum 1/2 inch angles together{
using the dark slide plus a piece of scotch tape, 2 mill, for expansion
as a spacer between the two angles } and glue the angles together ... the
Profile formed will be in the shape of a " F" and will be perfectly spaced
forming the dark slide track.. { There is a little more to the process such
as first forming two frames out of the angle ( one smaller than the
other ) and welding the corners prior to gluing them together to form the
"F" dark slide profile... It will be like putting two picture frames
together , one inside the other and then gluing ... }
I am really exited about this new film holer design as it will allow us
to make large film holders and mammoth cameras very easily and cheap.. I
will be building the first prototype in the near future and will document
everything..
