19 mm Sennheiser in 25 mm micro holder

[Michael Mann]

How do I attach a 19 mm diameter Sennheiser MKH 418 in the 25 mm diameter micro holder of the A1? Is there any "professional" solution?

[Chuck Fadely]

Gaffer's tape around the barrel.

Seriously. Can't get more professional than that.

This will be harder to come up with, but definitely cleaner than tape: find the right size rubber bushings. You'll need a couple of bushings, each with an inner diameter of 19mm and an outer diameter of 25mm. Will take some legwork and a trip to a hardware store or two, but it's definitely do-able.

[Jerome Marot]

Just an idea: in harware stores, you will find some slit foam tubes to insulate central heating pipes. I wonder if the right diameter is available...

[Michael Mann]

Thanks for all of your proposals. Foam tube or rubber bushings sounds "cleaner" to me than Gaffer tape.

get some weather striping tape from hardware store.
its foam and sticky on one side, but is usually white if that matters

OR get velcro tape, its sticky on one side and soft fuzzy on the other, black, but doesnt come in different thicknesses

OR some places have foam cushion tape that you stick under vases and things so they dont scratch furniture

[Dave Stern]

the design of the holder seems odd to me but maybe there's a historical (or cost) reason for it.. not sure why it wouldn't open on both sides, with mutliple thumbscrews (2 with 2 pins, or 3, or 4) and just tighten down on both sides to accomodate a range of mike sizes..electrical tape on the mike was what I used but it lets the mike wobble a bit b/c it's narrow

[Bill Pryor]

My old Sony mic fits perfectly. The Sennheiser MKH60 looks very slightly smaller in diameter; if I use it I can slip some doubled up rubber bands over it, and that should make it snug enough.

[Chuck Fadely]

You don't like gaffer's tape? Ok, then try this: self-stick velcro; the soft "loop" side. I have a Sennheiser with gaffer's tape and a Rode with velcro. The gaff tape looks more professional but both work fine. Despite the costs, these things are just tools. Whatever works.

What do you think about these O-Rings from MSC Industrial Supply. They are $4.90 for a package of 100.

Inside Diameter: 0.750 In. (19.05mm), Outside Diameter: 1.000 In (25.4mm)

The thin grey foam that protects a Lowel light bulb inside its little cardboard box has worked fine for us.

We switched the stereo mic that came with the camera (thick barrel) for an AT short shotgun (thin barrel) and used a piece of that foam and it not only acts as a shock absorber, it also holds the mic firmly enough.

You could even double up (use two pieces of foam) if necessary.

Saved us a bunch of money, and looks really unprofessional:-)

I like the o-ring idea, no tape or glue required. Consider too that a low-temp silicone material will provide a bit of isolation from mechanical vibrations. Consider McMaster-Carr Part # 9396K31

A full shock mount (with the rubber-band suspension) would be best - Is the mic mount removeable?

[Chris Hurd]

Is the mic mount removeable? Yes it is, see these threads:

I like to just wrap a rubber band or two around the mike. Easy to remove and gives a little bit of vibration isolation. Use the wider size bands.

I have an old foam wind shield that slides onto the mounting area of my sennheiser which compresses down nicley when clamped onto the Xlh1 and also gives a bit of protection to noise should you accidently knock that end of the mic
