I'm looking for something to link a 1/4 inch female socket to another similar socket.
( I want to connect a small ball and socket head to a binocular to tripod mount I have.)

Any suggestions welcome

A length of 1/4 in studding would do it. Any mechanical workshop (e.g. a decent car garage) could sort it for you.

Get my test cards document, and cards for 625, 525, 720 and 1080. Thanks to Gavin Gration for hosting them.

Or if you've got a long 1"/4 bolt and are handy with hacksaw and file, you can DIY.

As Alan says.
B&Q also sell it typically in lengths around 12 inches or longer.
You will probably also need 2 spring washers (serrated type probably best) and a couple of wing nuts for easy use. My small local hardware store would be better for this than B&Q.
Although local shop is typically dearer, you can buy just a few washers etc, rather than a packet of 50+. The small shop also means the un-packeted items can be screwed together to test plans.

The spring/serrated washer is quite important if you are thinking of clamping it to the back of a F1 car - we wouldn't want it coming undone at high speed.

From memory, 1/4 whit is the same thread pitch as UNC, well as near as matters, finding 1/4 whit studding might be difficult in your local DIY or Garage, It`s not been in common use since late 60`s/ 70`s. The use on tripods etc is a throwback to early last century.

The pitch is the same as Whitworth, but the thread profile isn't. One way, the screw will be tight, the other way loose. Can't remember which way's which though, but both are good enough provided you've got decent spring washers involved.

Thanks all, I'll have a sniff round local hardware shop(s).

I've got a Sachtler video head, an immense improvement on the Gitzo and Manfrotto heads I've been using up to now.
I found via another forum an outfit in Canada advertising an arm designed specifically for attachment to "most" Sachtler heads via the spare pan bar fixing rosette and particularly suited to mounting a video monitor. Not cheap though!

I e-mailed asking re stock availability, shipping times to UK and whether it would fit my particular Sachtler. B--- all reply. Dontcha hate so called professional businesses who don't reply to e-mail enquiries?

However I've found that I can attach my redundant Manfrotto pan bars to the Sachtler, not perfectly, but enough to provide a platform to which I can mount my monitor provided I can get said 1/4 inch screw. I've got a device (Opticron 31006) for attaching a binocular to a tripod which device will fit, just, around a Sachtler or Manfrotto pan bar. I'll be getting a mini ball and socket head, thus the need for a "go between".

I own a Canon XLH1 which has an awful viewfinder hence I use a monitor for focussing.

B&Q don't sell anything non-metric. If it helps, aldi are selling tap and die sets with 1/4"UNC sizes included.
