Re: OPCODE 1-E Mono Cutterhead (Presto 1-D Clone)
I'll have a new OPCODE 1-E clone fully built Sunday evening and bench test posted here. I've had to make a couple tweaks to some parts to accommodate the armature design I've created. As of now, the build seems like its going to be very impressive. I can't wait to actually electrify the voice coils....

Presto Armature Brass Part 2
Looks great on the bench. Can't wait to put the spring holes in and install this in the next OPCODE 1-E Presto Clone!

A cheap routing mill from home depot used to face a rough aluminum block. Worked very well. But dangerous!

Making a Helical Tension Spring for the switchblade head popping mechanism in my lathe overhead suspension box. I machined a Mandrel from Aluminum Round Bar. Axial 2.5mm hole drilled on the lathe with the bit in the headstock and the part in a v slot tool holder. Moved the tool holder to a vice and ...

Re: OPCODE 1-E Mono Cutterhead (Presto 1-D Clone)
You know this is a Presto 1-D clone right? It is modernized. But, a dynamic mono cutterhead nonetheless. Are you confusing this with Mantra V2??? Either way, I had access to a VR cutterhead. I took measurements with a caliper and created a CAD drawing of the body. This includes measurements for wher...

Re: Mantra V2 Stereo Feedback Cutterhead
I still plan to come back to this idea in V3. This video breaks down how you can use a diode laser as an interferometer for sub-micron vibration measurement. Specifically amplitude of signal. Which is all we actually care about for feedback. You wouldn't be able to monitor this like you can standard...

Re: OPCODE 1-E Mono Cutterhead (Presto 1-D Clone)
Interesting. Well, I can say these sound f-ing nice. Another thing to consider. Unlike a spring in a stereo 45/45 style transducer wherein sound transmission is through the spring more or less directly, these only supply tension. Shot springs or springs made of thinner wire will be more bass centric...

Re: OPCODE 1-E Mono Cutterhead (Presto 1-D Clone)
Presto Spring Clones Oringinally, clones were produces by a commercial spring maker. They were too small diameter and would compact too easily. Which meant too much low end. They were also made from some really cheap music wire. And the ends were rough cut. They weren't rounded I requested. They al...

Re: 1C cutter head
I can rebuild it to 8 ohms. My work is exactly comparable to original factory work.
These were all crusty, dirty and non functional when they arrived. This is how they looked after rebuilding.

Ahhh.... I was responding to the wrong comment anyway... oops... I pretty much put things on hold. I created a Presto 1D clone in the interim. I'm now also making a small portable lathe to run the OPCODE 1-E on, as well as Mantra. I've designed and am currently building out a miniature version of th...

Re: OPCODE 1-E Mono Cutterhead (Presto 1-D Clone)
A while back I started a complete overhaul of my RCA Portable Lathe. I cleared out the wood box, fixed it up, painted and clear coated it. I also stripped out all of the gear work under the turntable. Then, this sat on a shelf for years... Since I can't find a local Presto 6N to test my OPCODE 1-E c...
