Hi everybody,

I'm new here and wanted to start off by showing you the mic I'm busy building.

I will post the pics later this morning (South African time).

Hope you'll enjoy it.

Ok...

This is where I started. I used a green foam sponge. The kind you use to stick the stems of flowers into. When it's dry it's amazingly easy to shape with practically anything.
Foam mold

Then I covered the foam/sponge in cling film. Using a twin-pack epoxy called Steenvas (pronounced Steen-fuss) I made a pancake like shape and lay it over the cling filmed foam. Below

Then I waited a few hours for it to dry, before removing the foam. Then I marked out the area for the jack and volume pot. I put the holes in it so the excess epoxy would seep through, making it bond like a rivet.

I then mixed up more epoxy to build the jack and pot housing. I used a cereal box to keep form. They tear off pretty easily.

Then it came down to the element. A friend kindly had and old telephone with a nice element in it.

I then decided to customize the "grill" of the phone.

Jared - Your pictures aren't showing up. I suspect you may have got some html a little wrong. See the forum how-to for information on loading pictures, sound files, etc.

I've put a link to the images for you so people can follow it and see them. Jared's Mic

Thanks Kingley.

I used the "how-to" section before posting. Not sure why the images aren't showing.

I'll try edit.

I used a stress ball (not sure if it's an international term) to house the mic element.
Rubber foam
Mic w/foam

This is what I have so far. I will update when I have more shots.

Any advice or tips is greatly appreciated.

Cool. I have often thought of doing something similar, with fibreglass. I 'd like to do one from timber too, but the challenge is always how to do a decent grill. I like your solution.
Look forward to seeing your finished mic.

Thanks didjcripey!

Yeah this is the initial stages. I will be using a gel-coat fiberglass once the surface has been sanded even.

I've been given an old dynamic mic to tear apart. So if this element sounds rubbish, I'll swop them.

I would ideally like to get a custom grill mad with a nice curve to the face. All in due time.

Regards,

Jared

You are quite the handy guy. Fascinating stuff. More of a challenge than the "Bottle 'O Blues" approach, which fits my technical skills more closely. I await the sound. Keep us abreast of your progress.

Thanks for the kind words guys.

Making a stubby dynamic too. It's going to be interesting.

Will take pics of that too.

Hi Frank,

Oh yes I have. I have had my eye on this one Step aside botmaker
I use to work with CNC machines, so I'm pretty keen to design a mic grill and shell then get it machined.

Regards,

Jared

So I put together a little project (and by little, I mean a couple of hours of work). Super simple cut and glue job on an old Dynamic mic.
It still needs to be cleaned up and painted.

Dynamic Mic 1
Dynamic Mic 2
Dynamic Mic 3
Dynamic Mic 4

FM, hmm, maybe someone should make a coconut shell mic. Or bamboo. :)

Can someone please assist me in identifying the mic element pictured below
Mic Element
The text reads TX STC 4S 81/35

Just need to know what type of element it is.

Thanks

EDIT: I found Sontronics STC mic ranges, but nothing in my numbers.
