Idk what their tolerance is. My measurements are done with a run of the mill caliper. But each one is measured until I am absolutely certain. I sand down the edges and measure every few strokes and the end measurement is taken about 5 times to know for sure and I can pass it.
BigE,
It is hard to compare a stamped aluminum lamella to a composite part made with a different shape. I have some future ideas for Magnasanti to try but one thing at a time. I don't think that 0.25mm is going to cause any problems with sound quality or working tolerances, that is only 0,010" a very small difference that could be greater on a stamped metal part.

All cut
Lamellas are all cut and ready for gluing. In terms of laminate quality this is better then the previous attempt due to added care in the layup process and post process.

This the closest I have come to making an mbl quality driver. This is due to a new found care and process route in laminates, cutting, craftsmanship, and rigs.. Take a look and tell me what you guys think. The inner sealer will be attached tonight.

Fins can also look really good as MBL 101MK2.
I cut it out narrower neoprene lid.
The shape looks perfect.
I shine the lamp into the balloon.
Arrange the seal when the adhesive is liquid.

"By Jove, I think hes' got it..." *G* Lookin' good....

No I am not using infusion to make these laminates. I am just using a vacuum and a proper technique for the lay-up and post process. I really like the matt Finnish in these that matches the mbl look. This is due to using frekote as a release agent. This One I feel is pretty close to mbl quality I still need to work on a couple of things that if I decide to make another It will be simply for the purpose of making a perfect mbl quality driver. All others will be made for experimenting to achieve better than this control measurement.
It looks great, and the care in making and assembling is very evident in both the descriptions and photographs. I would not be surprised if at the end you end up out mbl'ing MBL.. 😀
this thread is till one of the highest ranked in no compromise no cost object DIY. i many times wondered if this whas just for you or is there any comercial benefit to it >? everything is done so well. and never did something to skip on costs. its a sick thread to follow !
keep up the good work its verry interesting!!

Thank you guys for the kind words. I would have never thought you guys would say the things you have to a wannabe MBL builder so it means a lot. No commercial benefits so far, maybe in the future. Any ideas what you guys would want? Let me tell you guys, this speaker is very challenging to build.
This is the first speaker with no audible voice coil rub and buzz from any distance just clean sound a landmark which any builder of this speaker can be proud of. I will post videos later. Measurements will be done later when I get the stand made.
Recording
Here is the recording hosted on sound cloud. Recording doesn't do it justice I think omnis are hard to capture as they sound different from room to mic. adjust volume as mic position changes.

Full plans (after all it's diyaudio) with comments ? ;-)
Ready made parts (such as lamellas, metal parts) ?
Full kits ? Partial kits ?
All of the above ?
On the other note, if you're going to make bass driver, do you plan to use thicker carbon fiber for lamellas or aluminium as on original MBL (it's probably next to impossible to diy them) ?
