My chassis is almost done now, finally.

Took a quick pic this morning, lighting not good, but will give you an idea.

The front accent pieces cover a drilling mistake lol.

I tried to add a pic of the top, but I think I reached my size limits for uploading pics maybe?

Beautiful wood work! The Lacewood looks great with the Quilted Maple! Nice dovetails too!

Thanks

I'm really happy with the final result, but it took MANY MANY hours to get there. My first big woodworking project, so I had to learn as I went.

For both the maple and the leapardwood, I took small pieces of wood and tried a few different finishes, to see which finish came out best. Did a lot of research online on finishing maple when I was working on the main body.

Stunning work, especially for early in your journey. Congrats!

My first proper humidor was made a long time back for me of birdseye maple and Australian paduk. Something about wood boxes that makes me smile...

Thanks. I did take this on later in life, so although a first big wood project I have lots of experience building stuff.

I have a scrap piece of paduk, and am thinking of trying to make a volume knob with it. Hopefully I can make something nice looking.

Did this today. Dual headphone connectors.

Not my amplifier.

Listened to this for the first time today.

Pad is from a SR-007 and cable from an old Lambda and the rest is home made. The main parts are made with files from Wachara (chinsettawong). Many thanks.

A lot more has to be done before it’s a decent headphone.

Nice! That's been on my project list for far too long.

jose · April 30, 2019

Very nice. I also plan to do one.

Opened up my SR-007 today and checked out the stators. Then I made this (left, stator to the right is the first I made)

– it’s almost the same dimensions as the Stax. Diameter of the perforated area is 1.5 mm larger on my stators. Hole diameter is 1.0 mm, 1417 holes. Also made another diaphragm but it plays very soft so the imbalance is total… but it's slowly coming, maybe it needs some time to charge - I don't know.

You guys should try this, it's really fun.

For information about building electrostatic headphones jump to head-fi and this great thread.

*chinsettawong* · May 3, 2019

? It’s nice to see you already get hooked into making the headphones. I’m sure you’ll figure out what is wrong. What spacer thickness do you use?

*JoaMat* · May 3, 2019

I use 0.5 mm spacers. So far I’ve made just three diaphragms and I have to learn how to get the right tension and also to get a good coating. After a few hours it seem that the new diaphragm is catching up with older one… and they actually are quite alike.

*chinsettawong* · May 3, 2019

Do you notice that with the new stators you've made, the phones sound less bright?

*JoaMat* · May 3, 2019

One side is with the “old” big holes stators and the other side has stators with small holes.

I do feel the one with new stators ( small holes) is slightly less brighter. The phones have no dust covers and I hold the phones with my hands against my ears. As for diaphragms they are as they happened to be. I have no control over tension nor coating, so probably lots of factors affecting the sound. Today I’ve been struggling with Sketchup and 3D printing. For me it’s a slow progress.

*chinsettawong* · May 6, 2019

Your arcs and headband look exceptional. Very nicely done! Are they 3D printed? What material do you use?

*JoaMat* · May 6, 2019

Thank you. Yes, they are 3D printed. I’m using PLA filament but the intention is to use PETG or Carbon. For now I make a lot of prints. I have to test and then make changes and test again - a very slow process. I made a solid headband looking about the same as the one you see on the picture and it was very stiff - practically useless. So I removed 80 % of material and then it became a lot better.

Sonically my Stax headphones are better but my home made one is much more fun to listen to.

*chinsettawong* · May 6, 2019

Believe me; soon you'll prefer your DIY phones "sonically" over Stax.

Then I can sell my Stax phones. Considering the price level for used stuff I might capitalize them and buy myself a Mercedes Benz.

3D printed ”pad holder” today. The grey thing attached to the driver unit with six screws.

SR-007 ear pad in place.

Then take the package and push it into the frame – done. Found a piece of aluminum net and with some black paint it will serve as grill.

Exposed cable connections. Have to fix that some time.
