"Millett Hybrid" redux: NuHybrid headphone amp, using the Korg Nutube - Page 7

Looks great!! Good 'ol Neutrik locking TRS and Alps Blue, can't go wrong with either. Do you have a Greenlee punch for the DIN size stuff?

I do not, but now after I have googled what it is I wish I had :-)

I usually build my panels using a good old drill, Dremel and small files...

Last time I built a panel I promised myself to use the 3D printer and print a panel the next time, but naturally my old one is broken at the moment and my new one is still in prototype stage so it's not usable yet.

 

Have you used a Greenlee punch? Are they good for aluminium panels and such? No bending of the panel when using it?

I have four of them, one for DIN connectors and the rest for tube sockets. They're exquisitely expensive but worth it if you build a lot. Great for aluminum, steel and copper as long as it's not super thick. It won't bend it. I've heard of people running into problems with diecast metal, but I've personally had no issues. Gives a super clean cut... no need for deburring, etc. 

 

Looking forward to see that 3D printed panel when you're back up and running :) 

 

As far as my NuHybrid, the parts are coming... I just have to be patient. :cool: Trying to decide between a Hammond case and a cigar box for enclosure.

I just cut my panels with an abrasive waterjet system.

Eric, since it sounds like you have it the easiest, want to cut ours out too? :tongue_smile: :beerchug:

haha that might be doable .  . . . 

 

I frequent a makerspace that has a small 2-axis waterjet system. About a 3'x7' cutting area iirc. Costs $55/hr in increments of .01 hour for me to use it. That's only slightly low pricing (an hour of cutting uses $20 worth of abrasive and a lot of electricity) but i also have a key to the shop and can wander in and use it whenever i want. The university charges $1/minute but since i am not a student or even technically a faculty dependent anymore i would have to talk my way in, and they probably wouldn't let me use it at 8pm on a sunday. 

 

I am considering cutting faceplates for some amps out of stone tile. I got some really detailed vent work going for my Max.Custom tube protectors are standard hardware + a few minutes in cad + a few minutes cutting + whatever finishing. Waterjet does leave the edges of soft metals kinda rough, and sometimes there is some haze from overspray during piercing. 

 

I might be willing to cut out some panels for cost of cutting + donation to the makerspace. we're too disorganized and chaotic to figure out how to charge people dues let alone how much that should be but every now and then we get in commercial waterjet work that pays the bills for a month or two.

Nice! There are similar places in Baltimore / Catonsville, MD, but nothing with a waterjet system... and they are quite disorganized as well, seems to be par for the course. I'm certain some of the people here would be interested, and a donation to a facility that empowers builders to build is an easy spend in my book.
