Help needed to find this item

[Eskimowe]

Hi, I hope you don't mind me posting here. I am trying to find a particular item to start a project as the specific ones for the job cost £150. The best way to do this is to provide you with pictures.

Ok, so we have here a quick release device to clamp onto a metal rod. Does anyone know where I can buy these? It doesn't have to look exactly like the one above. The red part is the handle which twists and closes the clamp together. The diameter of the rod to which this clams would be roughly 2-3cm, exact measurements not important at this stage.

Many thanks in advance.

clearly the items illustrated are high quality components but for £150 they should also be gold plated and studded with diamonds...

i have seen something like this before but cannot remember where and it is bugging me. got a feeling it was something to do with some equipment made for the disabled...

there is a company called pera in melton mowbray who specialise in developing products for other companies. it is possible they have a database of useful bits and pieces.

another company called rs components supply a huge amount of unlikely stuff as well as the electronic gear they are reknowned for...

alternatively a walk around your local industrial estate asking daft questions might prove fruitful.

if your project does not require such high quality; it would probably be cheaper and easier to have them manufactured locally. there is still engineers who will produce short runs of items on manual machines. depending on the strength and accuracy required they could either be part machined/part fabricated from sheet and use stock fasteners or wholly machined from a variety of materials from stainless to solid teflon.

holscot, here in grantham, is the king of teflon.

A Camera Tripod has these on the extending legs, I bought a second hand one for £10, maybe they could be adapted to your purpose.
