Topic: AKG Active Project part 4

[F.O.Bean]

I have 2 shure donuts and I still use my cheapo windtech rubber mount like those are

Not that I have a say or that there is time to change the design, but I agree that this current solution will not allow the use of larger windscreens and I think it would be hugely beneficial to design a collette that will fit the Schoeps delrin mounting bars. This would mean a hardwired cable, but that's never been a problem on most of the active setups already available.

I have a clip that I believe solves all of these issues fairly elegantly, and allows the use of schoeps bars.  I will probably productize it once the active setup is actually available.

Will this clip fit our Gefell actives too?

My uncle said he just needs the EXACT measurements and he will spit out a few pieces of the brass collette

Pretty sure this is it:

the inside MIGHT be 23/32 instead of 11/16
ts machinist said that was the correct size for the threads to be made via the tap
jon said go with what he says

Also, do yinz expect my uncle to to the tap threading? Im not sure hes capable of that!

Beaner....Jon Naiant has the tap for the AKG threads...if you sent the colette to him I suppose he could make the threads for the test subjects...then whom ever goes into production Jon has said he would ship the tap to that person.

he prob has a tap already, most machinists do have different sizes

3/4 -32 tap and 23/32 bottoming out bits are oddballs. About 50 each. I just happen to have both.

update: my machinist is almost done with 2 brass pieces, no stepdown, 21mm OD top to bottom. After that and Jon's approval on the first 2, I will have him do 2 pieces with the stepdown to 18mm. One of the problems with the stepdown is it leaves the walls at the base of the colette very thin. A solution may be to eliminate the chamfer at the base.

I'm looking forward to something "concrete" happening here.  Thanks for your efforts!!  Gefell users are monitoring this project too in the hopes that we will also reap the benefits of Jon's electronics...

what is the benefit of tapper down vs straight? and what is a chamfer?

Glad you asked will. I believe the tapered/stepdown colette is the one that will work with the nola style bars, but I'm not sure on that. The chamfer is the angle at the bottom of the colette. In the drawings it's real close to the inner wall of the colette. When we were cutting one out of aluminum it collapsed. I will find out if it will work with brass.

thanks

Well it's been almost one month since I offered to help out with the colettes. Took longer than I thought. These are ready for stuffing and testing.

Awesome!
