[LargeFormat] how short is a rail

[David Swinnard]

Philip

The shortest Sinar rail that I'm aware of is their 6" (15cm) extension rail
(#421.21). It is intended to screw into the basic 12" "basic rail". Each end
of the basic rail unit has an adaptor into which the extension rail screws
(once the screw on end caps are removed.)

Each extension rail has "bolt" through it with a "handle" on one end onto
which the end cap is screwed after the extension is connected to the "basic
rail".  The end cap is "lipped" and prevents the standards from sliding off
the rail inadvertently.  According to their documentation they do make a
"SPECIAL RAIL CAP #428.31" that fits onto the "bolt" end of an extension
rail when it is used alone.

So, the short answer is 6" (but a different cap is available for each end to
prevent the standards from sliding off.

Both ends are vital if you intend to install the end caps. Also, there is a
metal bar down the length of the rail (to prevent rotation of the standards
and tripod adaptor) that is screwed onto the rail at the ends. Cutting the
rail would be non-trivial.

Hope this helps,
Dave

I was considering a cheap Sinar to use with a bag bellows, a Calumet
rollfilm  back and some Super Angulon lenses.  I am trying to get more
rising front than my Century Graphic permits.
What is the shortest rail Sinar produced? A short rail makes for a more
compact 5x4. I could carry a second rail of the same size.
Is it a simple matter to bolt on an extension rail when a Symmar lens is
used?  Can a rail be cut down or are both ends vital?  Thanks for any
comments.
Whilst I write, hallo Uncle Dick did your parcel arrive yet?
