Soliloqueen's k87(k67) and k47 capsules

[soapfoot]

Agreed as well

I haven’t installed the first K47V I bought and am tempted to buy another once the in-house metal is ready, just because you seem so much more excited by those

Would love to get your honest sense on whether the in-house metal iteration will be substantially better than the first run

we're doing final bug hunting in the g code for all the parts. we've already found and fixed most of the bugs in the backplates, but check out this funny bug in the validation samples for the M7 mount. I'm using fusion 360, so instead of doing nurbs modeling like a sane person would in solidworks or something, i just used a ****-off huge fillet command:

That means that there is a line boundary in this curve where there shouldn't be a line boundary. A human would look at this and realize that it's from using a fillet command and understand that this is supposed to be an uninterrupted surface, but CAM software does not understand the concept of shape. It is programmed to generate toolpaths that ensure that each face fits the drawing within a certain percentage error. It looks at this and goes "oh, two faces!" and generates ideal toolpaths for each face. But it doesn't consider the area in between the faces, and it cannot create an infinitely small boundary between the faces, so the result is:

sorry for the dust i'm handling them with my fingers in my home office which i know I shouldn't do.

the CAM can't generate correct toolpaths for the shape, even though it can do the faces fine, so this will need to be manually altered.

I'm not going to go out of my way to hand-polish the mass production m7 mounts or anything, so I wanted to figure out how good we could get a purely machine finish on these parts. The results are not too shabby:

considering that this is not one material, but brass that we nickel plated after without re-processing, this is pretty good for a machine only finish. this should be nice and cheap for us to do at volume and, most importantly for a small 5ish-person shop, almost zero human effort-time

I think there shouldn't be much demand for this M7's mount, and it won't have an impact on the sound. Additionally, many finished products come with this mount, such as Thiersch, 3U and WET. It would be better if the cost is invested in capsules. Because we look forward to your new K47 being launched soon.

I disagree: At least here in Europe you can't find any properly made M7 mount for less than 60$ plus VAT, shipping etc.

So if Ari was able to offer a well made M7 mount for less, I see good reasons for her (and the market) to proceed with this.

Although the price for the amazing Thiersch STW7 capsule is astonishingly low (only 310 € plus VAT etc.), it doesn't come with the STS7 holder. It needs to be ordered separately (see your picture with all three heights available).

This is sold individually, I have bought it several times, more than 50 euros a piece is still acceptable to many people, I mean such a simple accessory does not take more time, and may not make any money at all.

I like precision milling the mount because I can design it in such a way that the outer diameter is referenced directly to the minor outer diameter of the m7, so regular screws can be used instead of grub screws and they will simply bottom out against the bottom of the head exactly when the M7 is secure.
