Default The Drawings in dvg-format

hifiZen

Is it possible to get a copy of your drawings in dvg-format? Im trying to make new drawings my selves in order to build a pair A166 mkII Layertone-style. It would be very useful to have your drawings to verify my drawings so they mach the original as much as possible.

Do you mean .dwg? I'm not sure I can convert to .dvg, but I'll have a look...

Hmm sorry, AutoCAD (at least, the old version I have) does not have an option for exporting to .dvg format.

If you would like a .dwg file I am happy to provide it, though I'm not entirely sure you should use my drawing as a reference - it's currently the version most removed from the original design. I don't feel especially confident with it, and would still like to get my hands on whatever dimensions, handwritten notes, or other drawings anyone out there has, which refer to something closer to the original design.

Update:

I just found bobmar's notes in another thread... looks like there is at least one dimension correction which is missing in my current CAD reconstruction. I'm going to try and work that in, will update again when it's ready.

Sorry for my bad spelling. I mean .dwg (AutoCAD).

I have full understanding if you dont want to share a drawing that doesnt feel accurate enough, especially in respect to Rons original design.

However I would be very grateful for any drawings of the curved design as well as the flat panel design, to compare and work with. Im looking at the drawings I can find and Im trying to figure out how the curved design should look like. But the only thing Ive found on the curved design is the pdf-file posted on planet10s site. I took that pdf-file and imported the picture of the curved design into AutoCAD and have tried to redraw the drawing, see the image below.

So , the original order was:
(1). a straight expansion (no curves)
1. A curved design extrapolated from the straight.
2. A flat panel design developed from the curved version.
3. Re-design from the flat panel design to another curved version by Tony.
As far as I understand, that curved design in the paper is labelled Rev: D and the flat panel design in the same paper is labelled Rev:G. Does any one knew if the drawings labelling are complying with the design order Ron is explaining or is the curved design labelled Rev: D actually the re-design (no.3) made by Tony?

No problem about sending you the CAD file, I just don't think it's ready for prime-time yet. Anyway, it seems I have one more correction to apply, so I'm working on that. Send me an email, and I'll send you what I've got.

Yes, I would love to have the center points and radii from that rev D plan - it appears to correspond to no. 1 in Ron's lineage... the curved design extrapolated from the original straight taper, but that's a guess on my part.

Reading the other thread, it appears as though maybe bobmar has those curve dimensions... I've emailed him to ask if he can send me that info.

Hello Forsman
I also want to build these speakers was wondering if you have made drawings, or get drawings of the curved version? Looking to try sonido 144 in my but has a couple of 166 also,

Regards
Sweden

Hej Forsman
Hej Forsman
Jag vill även bygga dessa högtalare undrar om du har gjort ritningar, eller fått tag på ritningar till den böjda versionen?? Funderar på att pröva sonido 144 i mina men har ett par 166 också,

Good news! Turns out, Bobmar had a hardcopy of Ron's original rev G. drawing, complete with all the dimensions - x,y coordinates mostly - and was kind enough to send me a scan of it (Thanks Bob!).

So, now that I have the original dimensions to work from, I'm pretty sure I can straighten out the errors in my existing plans, and produce something faithful to the original design.

Stay tuned folks, I'll be re-working the CAD file this week...
