DIY Boom Arm Reflector Holder
Contributed by Ed Baumgarten
Fastening items to booms and stands is one of the most often and many times, most vital part of any studio.
Reflector holders available on eBay typically consist of a 'baby' boom and some sort of clamping device to hold a reflector. Some include a knuckle to hold the boom to a stand and some don't. Although this article doesn't show how to construct a knuckle, it does show how to make some pretty heavy duty clamps to mount to a baby or light stand to hold a reflector, use to prop a part (I use these for propping ALOT), hold a piece of fishing line that's holding a part, a flag or whatever you might decide to hold in mid air.

Your shopping list for a single one of these is as follows (you'll want a pair or more of these so shop accordingly, look for quantity buys):
1=1" 'A' Clamp
2=1/4" Wing Nut
1=1/2" Nyloc nut (hex nut with nylon locking insert)
1=1/4" x 3/4" Hex Bolt
1=1/2" EMT Conduit Hanger with bolt (mine came 5 to a bag, found in the electrical supplies department)
Grand total for a single one of these babies from my home center:
$1.35
The 1/2" EMT Conduit hanger is the key here. It will tighten down to fit a 5/8 Baby and will also fit around 1/2" EMT conduit (and light stands, and booms etc…..).

Assemble the parts as shown above. Replace the stock hex nut on the carriage bolt that comes with the conduit hanger with one of the wing nuts. Put the 1/4" hex bolt through the other hole in the hanger and fasten securely with the Nyloc nut to form a stud. Drill a 1/4" hole through one arm of the A Clamp and mount it onto the 1/4" hex bolt stud and secure with the other wing nut. You may want to put a 1/4" flat washer inside the A Clamp arm to give the wing nut a bit of clearance.

The assembled clamp.

Thanks for the DIY, I was trying to figure this out recently, instead having to buy a whole reflector arm setup.

I like this. What is the piece that connects the boom to the stand? (That's a part I'm having trouble coming up with)

I couldnt find that part but i just clamped this to a boom type mic stand i got at a hock shop for $12.
Works like a charm.
Thanks!

Thanks for the money saving idea. I was looking for a way to make a clamp and still use a boom arm, without having to buy a flimsy 'reflector holder arm'.

Hello Ed,
I just wanted to come back and say thanks so much for sharing this very detailed project with us. I just went out and got it done in a day. I bought a golf ball grabber and stopped at Menard's, a building materials store in Green Bay, WI, and found all the materials that you have listed here. The prices were a little different, obviously, but withing a $2.50 per clamp range. I was able to build my very cheep Reflector Holder for my Portrait Photography. Green Bay, WI can be a sunny place, even though everyone may think of it as the frozen tundra! :-)
This is the final photo of my project.
