The last few projects I've worked on i've tried a few different methods and found the prep work before the buffing stage is extremely important. I purchased some Dremel buffing wheels like the ones below to see if it would help me work out any imperfections left by my investment. I found that going from coarse to extra fine worked well and the wheel was able to get into areas I couldn't with a sanding block. Then used my table top arbor with a buffing pad and blue buffing wax to get it glass like.



You just buffed the face plate right?

WOW!!!!  Shilohjustice, that is one of the best looking shells I have seen on this thread.  Can you elaborate on your curing process?  How do you achieve such a clear/bubble-free shell? Very nice work my friend!

I appreciate the kind words, I'm at work right now but will post something about my current technique. Most of it has been taken from recommendations provided by some of the alumni here on the forum.

I have finished making my first pair with ED29689 but the the right side is much quieter than the left side from 20-1khz, is it possible that I have overheated the driver? The seal is perfect so it is definitely not the seal.

  I have finished making my first pair with ED29689 but the the right side is much quieter than the left side from 20-1khz, is it possible that I have overheated the driver? The seal is perfect so it is definitely not the seal. 


possible problems
1. Damaged driver
2. Shortcircuit at the driver housing
3. Shortcircuit somewhere along the way before the driver.
3. Damaged cable (f.e. jack plug).

I apologize for this question, but where do I start in this giant thread? I am brand new this game, but I want to dive head first. Is there a guide posted somewhere? Again I apologize, but 310 pages is a whole lot, although I'm grateful for all the wisdom in this thread.

They responded to Sonion from, they can send 1-1 pcs of armatures:
$ 2 piece of 28UAP01 price of $ 84.50 and 2 piece of 38AJ007Mi / 8a 60.50 price.

I'm happy because they are precisely the armature will be back to Angie that were in it. Thanks for the help!

Next week the shells come from the lab Microsonics ($ 50 a pair, wood faceplate and blue body) I asked him three pieces of 2mm hole. I will try my earphones Westone UM Pro50 drivers implanted in the shell. One deep (CI 22 995), one dual med and one dual high (both some twfk-swfk from Knowles) go to the three hole. But it is not clear how long to let the tubes (1.8 mm ID), because the high and med in Westone about 12-13 mm long and bass about 20 mm. But Angie was bass about 20-25 mm, mid of about 30-35 mm and high of about 50-55 mm.

Why is there such a difference?
I heard that the Freqphase system can build up ... maybe ...
