Thanks everyone for your comments ! Yep next post is about decal file finalizing .. specifically alignment testing...and I’ve convinced Jeff from Custom Synths that we should share the decal file with the world as well so there will be download!!!

Cheers !

great blog, though way too long for me to read right now considering i just discovered it so haven't read it in installments. looking forward to the decal part, please post soon! we have a jp8 in the closet that we're going to give a full facelift to once we find local shops that we trust to do this work. (we will be testing them out with lesser instruments like Star Instruments Synare 3s before we send them stuff of greater importance and higher value).

Hi all, the latest post is up! This one is a biggie, it contains download files of the Jupiter 8 panel artwork!! Which can be used to re-screen print the panel decal if yours is scratched or rusted.

You can also now talk to Cora! She has her own Facebook group! She enjoys hearing your positive support during her progress and answers questions !

https://www.facebook.com/groups/359832781432431/

Enjoy!

Cheers,
Darren

I loathe Facebook, but at least Darren is giving us prompts here on the forum.

Great progress! :clap: Keep up this fascinating work!

I've joined the Cora Facebook group, and therefore seem to be the odd one out :beamup:

You're not quite alone on there MW, I haven't joined Cora's group yet (my excuse is I'm a guitar player really) but I do use fb and while there is a lot of dross and far too many adverts I find it useful.

Note: If you edit the dropbox links to be "dl=1" instead of "dl=0", they'll be directly downloadable, rather than forcing the user to go to the dropbox page, and figure out how to download from there... :thumbup:

As someone who creates print artwork for a living mostly doing things that are similar in concept to your JP8 graphics, I think you did make the job more difficult than it needed to be, but at least you got test prints done and were able to tweak your artwork to get an ultimately proper fit.

However I did wonder why you didn't use the CAD drawing of the panels that you created when it looked as though you were going to have get the top panel remade after the powder coating disaster, as your starting point and the photographs just for reference?

O...K...

We've clearly moved on from cats and dogs. Glad to have caught up. ;)

Fair question....
Because
A/i don’t own AutoCad or know how to use it, I only know how to bluff my way clumsily through Coreldraw
And
B/ a friend in the UK is doing the Top panel cad file for free for me after reading Cora’s sad plight he offered to help because he felt my pain. I’m just sending him pictures (hundreds of them) with digital calipers across every part of Cora and he’s doing the cad in his spare time!

The laser recut of the top panel may never happen if the original one turns out successfully im just keeping all options on the table at this point !

Cheers!

I see. That makes sense.

I had assumed from your previous posts that the CAD drawing had been completed in CorelDraw, when it appears that they are still a work in progress.

I would have still started by creating an accurate full-size drawing of the panels with all the cutouts for the sliders and other controls in your vector drawing program of choice. Mine would be Adobe Illustrator - I haven't used CorelDraw since 1990 but I expect that it has kept pace with Illustrator in the intervening years so it should be relatively trivial to do this.

I would have then ripped the vector file into Photoshop at 120 pixels/cm, and lined up the photograph(s) of the panel graphics on a separate layer and using the warp and/or distort transformation tools made sure that the photographs lined up exactly with the drawing. Then I would have removed the drawing and saved the modified photo to use as a template in my drawing program. That way I would have known that my final artwork file was 100% accurate first time.

I would have also got all of this done and checked before I sanded off the original graphics.

Still I can't help but be impressed by the results, and everything else you have done is way beyond what I am capable of. Looking forward to the next instalment.

I'm glad you picked up on the fact that Roland uses JIS screws in its construction -- as does most Japanese equipment.

JIS screws look similar to Phillips but the required screw-driver blades are straight rather than tapered, and using a phillips driver in a JIS head will knacker the slots very quickly.

Most JIS screws are identified as such by having a small dot on the screw head alongside the cross (or occasionally a x mark).
