At extreme risk of revealing my depthless idiocy, is there a specific term for one of those things that slips over a junior pin ("TV spigot", brits) and pins in place so it can be hung on 2" tube?

It may not satisfy the safety regs as is,  but,  what MSE calls a Mafer clamp is quite useful.  It's just a simple,  ruged clamp that will clamp to lots of things,  including pipe.  You may want to check that the spigots that you want will fit.  I have what looks like a 5/8" baby pin on the one here,  but the fitted part (the part sitting inside the casting,  doesn't perfectly match up with the retainer pin or thumb screw.  Still works ok.

 

 Have a fossic through the MSE catalogue or "griptionary".

To answer Freya,  no,  I don't work for them,  but their stuff is good,  and their info is usefull.

 

You've probably seen the theatre pipe clamps already?  I've never used such,  but I have a couple,  with the safety wires and the ports in the casting for 1-1/8" and 19mm spigots.  There will be (should be) adapters for that which give you the 5/8 baby you need.

No, no, no, not a mafer. 

 

What you want is a Junior pipe clamp: http://www.msegrip.c...ipe-clamps.html

 

or  a little more versatile a C-clamp with a junior receiver: http://www.msegrip.c...s-c-clamps.html

The ones I have came, I believe, out of the BBC circa about 1970.

What's wrong with the Mafer JD?

I think JD is right.  The jaws don't really encircle the pipe enough to be safe for hanging a light overhead.  Otherwise I quite like the Mafer.  Hopefully I'm not misnaming it.  It's an old version of the MSE clamp.

 

Phil,  what's wrong with the clamps that you have?  If that's a 1-1/8" fitting you can get or make one with a 5/8" spigot on the end.

You have the correct clamp, be certain to use a safety chain, cable or at least a piece of trick line to secure the fixture yoke to the pipe.

 

Mafers aren't meant for heavy lamps, anything with a junior pin is at least a 2k and I don't believe a Mafer will fit onto a 2" pipe.

These big cast steel things came off 1200W moving-mirror lights (Clay Paky Golden Scan IIs, as memory serves).

 

Which are enormous, and incredibly heavy, explaining the sturdiness of the clamps.

 

If anyone ever sees any of these things... there's probably dozens rusting at (the now disused) TV Centre in London right now.

mafer and manfrotto pipe clamp.jpg That's what I called a Mafer on the left.  It does fit a 48mm pipe.  That may be a Manfrotto clamp on the right.

But the Mafer isn't designed to accept a Junior pin so unless you want to make a Junior receiver or have one machined for it, it doesn't solve Phil's problem.  Nor is a Mafer (or Cardelinni) the single go-to clamp for all situations.

With the Jr. Pipe clamp you can the use a Spud adapter to go down to baby 5/8"
