Sinar Norma Extension Rail

[Pete Watkins]

I feel really stupid asking this but I appear to have bought a Norma and for the life of me I can't see how to fit the extension rail onto the existing rail.
HELP
Pete.

Unscrew the end cap(s), line both up, screw it on by twisting the plastic knob on the extension rail.

Pete - your problem could be that the set is mounted on an extension rail - rather than a standard rail!
I don't think an extension rail fits into an extension rail.

[Frank Petronio]

You can keep extending the extensions to infinity but only one end has the threads. And you can't add a cap to the open/female end of an extension rail used as the main base rail.

If someone sold you a Sinar with only extension rails, you can still use it but you got a little bit gypped. That's the downside, often people build these cameras from leftover interchangeable parts....

[Clive Gray]

The base rails have a black plastic end that does not rotate you can add extention rails which have a red plastic end that freely rotates at one end to either end of a base rail. Joining extention rails together is arkward you can do it if you can hold the threaded rod in the open end still enough, however the approved way to do this is to use a specail rail end cap 428.31.000 it makes life a lot easier.

Sinar page for the rails


Any rail from any era is interchangable (with the exception of the Alpina rail)

I don't think I've ever owned a standard rail. All my rails (14 of them) are extension rails. Can't say it's hindered me.

Should the red plastic end of my extension rail turn? I think its seized...

[Frank Petronio]

It should turn....

[jonreid]

Ok. I'll hit it with some WD40

Thanks for all your help. I've got the same problem as jonreid, the red plastic bit is jammed (glad that I'm not alone). The camera is complete and as bought by a company who were the original owners. It was left laying about for years and the bloke who sold it to me left it laying about for at least 20 years so it needs freeing up a lot.
Thanks again,
Pete.
