That seems to be a common issue for the both of us, that 'driven element' that drives you nutz. But I will admit yours is more of a challenge and a feat to do properly. But you're doing great at it...keep on keepin' on.
Thanks Jerry CNC and 3d printing are my lord and savior

Amen to that! *G* I've yet to foray into 3D printing anything for my 'exploits', but printing metal does seem attractive...but not quite yet.

I've been struggling with that simple yet effective means of rolling materials for cones in a predictable fashion. I finally arrived at an approach that has those answers; more on that as I cobble together 'the widget'.

Meanwhile, our 'regular business' is on the cusp of a large project using the CNC source I used for the bases. We having him route 206 pieces in treated wood for the ribs of a 45' long fish play structure we're going to build for a town near Burlington, NC. Since it's size precludes us assembling in shop, it's going to be done outdoors literally on our doorstep. I suspect that might cause a bit of a stir amongst the locals here...not to mention when it 'hits the road' to the final destination...*L* Not often when one sees a 'fish out of water' on the interstate.

BTW, hope your going to join in the Great Migration to watch the eclipse. A cousin of mine remarked that it might feel like a national version of Woodstock. Well, a 3 minute version of it, Yes...it'll certainly be a national 'jam' both before and after fer chure. *L* Pity no chance for an encore if the weather doesn't 'shine' on the festival.

*L* It is crazy, but we're crazy enough to tilt windmills like that...

Nice piece of metal...no clue as to what it's for or will do, but...*G*shrug*

Yeah, there seems to be an uptick in interest 'bout them. The 'original' full-range versions like the F and A will still prove to be a challenge (ask HHR/Dale about that). There's omnis showing up in the 'digital assistants', but what I've 'seen' or aware of are still not a 'true' Walsh radiator...at least in the sense of the profile of the cone and the way it's implemented. But we'll see....esp. in pricing, which tends to be get insanely high for what basically isn't that difficult IMHO...

I'd like to take some credit for that 'uptick', but I'd be patting my own back in a self-delusional fashion.... *L* But it's an overdue resurgence in interest, IMHO. They're too revolutionary, underappreciated, and would make 'home theater' really ACT like it should. The MBL's (and yours *S*) are just the pinnacle of how far the omni concept can be taken, and how successful it can be.

I'll keep plunking away with my 'trash'....likely I won't be able to afford whatever and however the 'new Walsh' may be. And it keeps me off the streets and out of other people's hair. *L*

Hello,
David, Have you tried to connect MT50 to tweeter and bass?
Singles may sound good but they are verified together.
