Drilling aluminum requires higher speeds than steel. Way higher.
Get yourself a wheel and learn to sharpen tools (drills are easy to sharpen).
Use a punch to get exact location for holes.
You don't have to chamfer all the way, you can just chamfer a bit.
A deburring tool is what you want.

Put masking tape on surface to protect from scratches.
Lube/coolant makes life much easier...

On a cad milling machine, you could have these panels flying out the door.

Before getting panels etched etc. using my artwork know they weren't done to a template and some of the lines don't line up...worth editing them if building a system.
thanks for the heads up about the lines, i am going to have a friend make them the same .
made my first lazertran panel.
it would seem that my laser printer molests the paper as it feeds it.
mine is only a black,so i will see what happens when i find a color laser printer.
also got lazertran stretch on my first go :cry:

By the way APETECHNOLOGY, your etched PCBs look lovely, and they really capture the aesthetic of these early instruments. I went the same route with most of my 200 clones, using Mark Verbos PCB layouts where available.

Here's a better photo of a Lazertran'd brushed aluminum panel, some 6 or 7 years on, and it's mounted PCB. This panel has faired far better than most, and as you can see, it's decent, after cleaning carefully a soft tooth brush. There are dirt and grime marks that have built up where the decal is scratched or chipped that are difficult or impossible to remove without removing decal.

You can see, it's not terrible, but it's not ideal. Yes, it's a compromise.

If it's gotta be bespoke, there's always screen printing: the gold standard. You could probably get 3 or 4 modules on a screen for $100.

Can you clearcoat over the lazertran?

Sanders, thank you for the kind words!
also thank you for posting a pic of a module. i was going to ask for one.
that filter looks like it has a history!
i do have a silk screen set up in my shop. never printed on metal before.
then there is the route thc went and use Schaeffer.de — "They offer a service where they'll mill and print the panels at the same time. I use the option to under print the entire panel with white, for that original feel"
his looks exactly like the originals.
its a winter project so i have time!
thank you for your input,i appreciate it!

It should be possible but I have no idea if there would be any sort of negative reaction. Lazertran doesn't like alcohol, I've found, so no idea what else.
I just can't help imagining that this would be better with vactrols

I'd love to see his work. I'm curious to know if anyone has made the Buchla 100 Music Box style cabinets, as in the promotional photo.

On that note, if you look behind my 291 (and below), you'll see a Synthi clone panel I made. I had it powder coated Grey-White by Shaeffer/Front Panel Express in the US, hoping to achieve the Morning Mist look of early EMS stuff. Unfortunately, I missed that mark quite a bit, no pun intended. But it might not be far off from the Buchla white panels. I've never seen a Buchla 100 in person, but I'd guess they would have used a powder coat.

Buchla 180 Env.Gen.

Post by moogboy010 » Fri Jan 26, 2018 11:07 am

Hi Peake.Here is a picture of my proto-board,Envelope generator.Could not find,or make art-work,so I did it the old-fashioned way,I went thru torturous-hell for it.Used 2N3904's and 2N3906's.Correction to CBS schematic;R5,R7 and R45,R47 are all 47K,not 4.7K,as stated in lower schematic?Worked the first time I hooked it up.A little quirky ,but it works'!Build follows' the schematic exactly,only mine looks' like chicken-pooh! 8-)

Apetechnology;The 180 is a bit quirky,in that I do not have it hooked to the panel and the settings' of the pots' might be reversed on the outside legs'.Other than that,it seems' to work.
Update;I had the attack and sustain wires soldered on the wrong legs' of the pots'.Everything is working great.Need to drill panel and make artwork to fit my slightly larger face-plates.(5" x 7 3/8") 8-)

looks nice to me!
not chicken pooh at all in my book.
what do you mean its a bit quirky?
you inspired me to take up laying this out in pcb software as a learning experiment.
what is goofy? other then the component errors?

I can also confirm the lazertran doesn't hold up very well. My diy panel were amazing to begin with (10 or so years ago) but now they look like they have skin cancer. Perhaps if you do go with lazertran it might be worth applying some sort of clearcoat on top to seal and protect the finish.

It seems like Zthee has cloned most of the 100 series by now:

(Just for your inspiration, I doubt he plan on offering anything for sale)

I'll be available to build Zthee's 100 Series clones if anyone wants some and doesn't build. There are a few modules there not available from my series of clones.

Zthee's clones'

Post by moogboy010 » Wed Feb 21, 2018 3:09 pm

These modules' are beautiful.Love the fact that he has actually cloned the 191 filter! :love: Great work Zthee!
My art-work makes' me cringe, but I have larger panels' to accommodate some of my larger,proto-board builds'.I did get a lamonator,which helps' to protect the face-plate,but silk-screen can't be beat,for the real look and feel!!!!!

Nice work on the 106 moogboy010! If you drill out the two holes indicated directly above the word "Ground" at the power inputs, you can pull through a tie-tie and run the power wires through it for some strain relief.

Thanks' for the good advice on the strain relief,Peake! I saw where you had done that,on your 106! BTW; Was a little confusing putting this thing together,as to what pot and jack went to what!Ha! I did the solder-side-out and had to reverse everything. This mixer will distort a bit at full volume.My oscillators' may be a bit hot?

106 distortion

Post by moogboy010 » Thu Feb 22, 2018 4:05 am

The distortion almost sounds' like amplitude modulation!Kind of nice,actually. Can't wait to hear the ring modulators'!

Here is my "stick-built" ,buchla-ish model # 180 Dual Envelope Generator!Not totally pleased with the art-work,but it will do, in a pinch! System is starting to come together!Taking a lot of time to 'tweek' stuff! The Ring modulator,by Fluxmonkey,sounds' great!Building a second ring mod,for a model # 111 :eek: ImageImageImage
