Presto Armature Clone Nearly Finished! Hybrid Aluminum/Steel evolved armature. You see the steel crossbar which will hold the cutting stylus is not fully stuffed into this slightly imperfect part. Next attempt should be a winner! No holes drilled in these pictures. They will come. Also, when I've fi...

I've built out two of my universal Neodymium Magnet/Pole Piece combo. They are 3d printed plastic, steel inserts and neodymium magnets of standard sizes. They will fit original Presto cutterheads as well as my OPCODE 1-E cuttehread. Readings using a digital Gauss meter are showing double the strengt...

How to extract stuck screws. 0. Insure you're using the correct size screwdriver. Get as many small drivers as you can. I have tons of little ones of many widths and my collection grows frequently. I can now also custom grind my own tips. Also, insure that you are holding the frame tightly and you e...

If testing goes well this weekend I'll be offering Neodymium Magnet Upgrades for regular Presto 1-B, 1-C, 1-D cutterheads. These parts replace the existing pole piece and horseshoe magnet. They will significantly increase both cutting level and overall range. Stay tuned for further video update with...

A while back I had access to a Vinyl Recorder dynamic cutterhead. I drew the body in CAD. I've exported an STL and am making it freely available to the community. Enjoy!

Here is the VR Cutterhead body as STL. DIY until your heart is filled with joy...

Presto Bench Test Rig Video or How to Avoid Sniping I've taken a fair amount of heat from folks about the red solo cup. So, here's an in depth explanation of why I used a plastic cup to do bench tests on cutterheads that I either repair or build. Why this was ok, but not ideal. How the Presto Mono C...

Evolved Hybrid Presto Armature The initial cad, cam and machining of an evolved hybrid material Presto Armature Clone is now finished. I still need to add the V slot, drill the holes, and tap the threads for the stylus screw. But, otherwise, this is a viable part combined with the precision ground s...

Here's how to socket out a set screw with a 1.1mm end mill. I actually do all my own machining and am happy to show you how its done!

I spent the day sorting out how to grind the steel component of the hybrid material armature. Since I don't need a damper, I'm free to take liberties with the overall design of the armature. So, the OPCODE 1-E will have an armature that will not look exactly like the originals. But, it won't require...

I will keep you all updated in realtime. I actually had an idea last night about how I can machine the armatures from mostly brass with a steel part attached. Going to try making one today.

My new thread for the OPCODE 1-E Mono Cutterhead. The affordable Presto 1-D clone.

Bench test video here. Sounds amazing actually!

@handcut - I think that will be a reasonable price. Just depends on how much a lot of armatures comes out to. I don't plan to make those myself. Not worth the effort and not setup to cast or precision grind like that. @KNOP - I appreciate the enthusiasm. Thanks! I've also made a fairly impressive st...

Seven days ago on 1-30-2019 I had the idea to clone a Presto 1-D cutterhead. Seemed like something fun and quick to do since I’m so familiar with them now. It was quick. Frustrating, but quick. And, the results thus far are astounding. Its a 3d printed plastic body with the dimensions of a Presto 1-...

Hey! Thanks!

Much, much, much more coming imminently!

Excited as I am???

Some picture updates! Full Presto Rebuilds are now $400. I can replace coils on heads I've already fully rebuilt for $200. I'm also considering selling coil clones by themselves. However, I have news forthcoming that will make that no longer necessary. Get excited because I'm about to offer a very c...

The pre-order sign up list is here http://deepgroovesmastering.com/preorder.aspx I believe I answered your email, Dubwise. At the moment, I'm extremely busy doing the work you see me documenting. Once completed, I'll have more time. Either way, I always have time for customers. Just look at the feed...

Moving magnet actually works really well as long as you have proper feedback. As dynamic it is horrible. I think the entire world will be wanting to see your "Unique transducer concept" seeing as though transducer design has been relatively the same since about 1820. Me personally, I've looked at ho...

As soon as I finish the first round of parts, and then make a second full metal body, only then will I have a full understanding of the cost in man hours and materials that are required to produce each body. That information will be used to determine a final price. So, I can't commit to any price at...

I have a feedback summing preamp desing with VU Meters and IRIAA for Recording, phono preamp, 3 position channel selector for monitoring phono/feedback/inpu, all built into a 2U rack. I also offer a 3U rack which will have current meters, heat meters (using the same ac bridge circuitry as Nuemann), ...
