Useful Little Clampy Things

Posted by Tom Benedict on 20/12/2017

A while back I needed the ability to put a 1/4″-20 threaded stud… Somewhere. Anywhere. Everywhere. I tried some things on the 3D printer, but realized none of them would be as robust as I needed these to be. So…

I turned to Ebay!

A Useful Clamp

Turns out you can get insanely cheap clamps by searching on “super clamp”. Some come with T-bar handles, some with offset handles like this one. Some come with articulated arms (which I used for mounting cameras on our vacuum chamber for work). And some just come with 1/4″-20 and 3/8″-16 threaded holes. Mine came with threaded holes.

I added the 1/4″-20 threaded stud by chopping the heads off some bolts and cleaning them up with a grinder and a die. The thumb screws came off of a camera hotshoe to 1/4″-20 adapter (also courtesy of Ebay.)

All in all these things came together for less than $6 apiece.

A Useful Clamp with Shock Mount

My original purpose for these was to be able to space mics anywhere I wanted across a bar for trying different stereo recording techniques. To do that I needed to be able to mount any of my self-contained stereo setups, all of which take a 1/4″-20 thread, or to mount individual shock mounts like this one.

A Useful Clamp with Ballhead

But there’s no reason to stop there. Pop a small ballhead on one of these and you can mount a camera, a handheld sound recorder, an off-camera strobe, or whatever else strikes your fancy.

The only problem I’ve found with these is that the handles like to come off, leaving the clamp firmly attached to whatever you cranked it onto. If you decide to get any of these, be sure to test them first, and if any handles come off, re-install them using red or green Loctite. (I had to re-install three of mine!)

I wound up building five of these, but now I wish I’d ordered more.

P.S. Since writing this, I’ve been told this is all pretty standard fare for lighting and grip gear on a film set, and that re-purposing lighting gear is a cheap and easy way to build solid recording setups. My take-away: 1 – There’s nothing new under the sun with this article. 2 – My butt’s gonna go numb the next time I sit down with the B&H catalog or start surfing their web site! 3 – Neither of these is a bad thing.
