DR 250 in France...

[Kranku68]

No this this an ultra resistant Pu glue...it's not the transparent one you are using in the usa but it's an equivalent to your loctite that is quite hard to find here
It looks like silicon cause i've trimmed the excess with my fingers when it was not dried.
Don't worry it's also an expansive version and all will be really air sealed

ok today i've put horn sheats in place and begun to install the pvc pipes...
mine was a bit too "soft" ( 120 mm grey diameter wasn't in stock so i've used 115 mm roof gutter ) so i've made some little cleats to block them...

[Kranku68]

so life goes on and so do the building...
i'm reaching the dangerous point...the nacelles...

[Kranku68]

the nacelles are ont the way now...i'm going to attack the screwing system of the modules...

just a look at the DRs with the modules in place...

[Kranku68]

still working...

[Chris_Allen]

Keep going! almost there. You'll be pleased with the end result. I always look more fondly on the things that I have built.

[Kranku68]

hey everybody...it's been a long time !
so some progresses have been done...
it's beginning to look like big boxes !...

[Tom Smit]

Getting close!

[Grant Bunter]

Getting close!

And looking good!

Enjoying your build thread, thanks

[Kranku68]

hey it's been a long time since i wrote my last post...i've been quite busy doing my homeworks, ehhhh...correcting my students'homeworks !
We'll i've worked on my DRs the week end and i think i'm quite near to fire 'em up
so the tweeters modules are nearly ready, i've got some finishing to do to have them perfectly air tighted (see on the top and the bottom...little gaps to fill).
Screwing them perfectly with 3mm T-nuts was a little bit tricky but it's done.
i'm working on the filters now.

I didn't think that with the new Piezo module that the array had to be air tight.

[Kranku68]

honestly...i don't know if it's really needed.
i'm sure it's not in fact regarding to the plans.
but when i'm in doubt i prefer to be a psychopath...In France you can translate this by "who can do the best can do the less".

It doesn't, all that's necessary is that the module joints to the rest of the cab be airtight.

Am I mistaken, or does the DR250 use a 20 element melded array? I see only 18 elements on the OP's build, hence why I ask.

I noticed that as well.
I believe it should be 20 piezo's/cab, at least that's what mine are, and what my plans say...
