Make a Rubber Band Shock Mount for Your Boom Mic for Only $3!




Introduction: Make a Rubber Band Shock Mount for Your Boom Mic for Only $3!

About: I'm a tinkering filmmaker who likes to build stuff for my films.

When attaching a boom mic to a pole, you need a special mount to insulate the microphone from pole noise. If the mic is connected directly to the boom, it will register unwanted sound whenever anything hits or moves across it (like the operator's hands). Thus, you need a special mount that will 'float' the mic away from the pole. Rubber band mounts are a good way to do this, but are often very expensive (around $50). Why not make your own for $3 and put the rest back into your movie?

Step 1: Parts List

Here's what you'll need for this project, most of which I found at the dollar store:

1 wire mesh pencil cup (with mesh bottom)
1 piece of 1/2" PVC pipe scrap cut to length of cup
2 medium length rubber bands
2 hose clamps

The cup cost $1 and the clamps came in a variety pack of twelve that also cost $1. The elastics came in a wonderful bag labeled "One pound of rubber bands" (also $1) that I have used for many a project. I already had the 1/2" PVC scrap laying around, but even if you buy a ten foot length it will only cost $1.50. Cutting the PVC is a real pain unless you get some ratcheting pvc cutters, which I highly recommend. PVC pipe has so many great uses (it's sometimes call "the Tinkertoys for adults") that these cutters are a wise investment. Get them for a scant $2.49 at Harbor Freight ToolsHarbor Freight Tools.

Step 2: Bottom Out

The first thing you need to do is remove the bottom mesh of the pencil cup. I first tried cutting it out with small wire cutters, but found that pushing down on the mesh would break it free rather easily.

Once the bottom of the cup is removed, check the edge for straggling bits of metal that someone (like you) could cut their fingers on. Get some needle-nose pliers (I used the Gerber multitool that I always carry) and pull them off. I'm all for expending blood and sweat on a shoot, but tying up loose ends like this will save you some.

Step 3: Make Your Marks

Next, lash the PVC pipe to the cup vertically using one of the rubber bands. Then, using a marker that can be seen against the color of your cup, make a pair of short lines where the pipe meets the cup. Do this at the top and the bottom.

Step 4: Cut Holes

Remove the pipe and use your wire cutters to cut a path where your marks are.

Step 5: Add Clamps

Feed the hose clamps through the newly opened holes. This will take a bit of work and may deform the clamps, but don't worry.

Step 6: Insert Pipe

Run the pipe into the clamps, and tighten. The clamps will wrap around the pipe and the pierced cup and reform into shape.

Step 7: Rubber Bands to Finish

Finally, wrap a rubber band around the cup twice, so you have two bands next to each other. Do the same with the second band, placing both in an "X" formation in relation to the PVC. This will suspend your mic nicely in the center of the pencil cup.

And that's it! Run your mic through the center of both pairs of bands, attach the mic clamp to the PVC, and you are well on your way to cleaner sound, unmarred by any noise your boom op may make as they reposition themselves. The only thing else I might do is spray paint the PVC black so the whole thing matches and looks more professional.

    Again, why just post a link? His was made of different material. There is no point on posting your link. Stop being a jerk.

    I made this and I have a Rode Ntg-2 Microphone and a rode aluminum boom still picks up a lot of handling noise from this (I can hear the rubber bands lol). Though I think that its got to do with my settings...I still have a lot to learn.

    I made one of these shock mounts for our latest shoot and this thing is AWESOME! Our production team says it's the equivalent to the professional models costing much more than we made it for. Thank you guys!!!!!

    this is great! I just make one (still need the pvc part though) and it works perfectly. Awesome timing too, I just bought a recording system.

    Awesome idea! I kind of need this right now, we use my tripod thing, but it works well because we have this other part for the mic... but anyways, awesome Instructable, will try this out of the tripod is in use for something else.
