The Secret Society of Lathe Trolls

I'd like to point out something crucial: you said you simply used the RIA curve in Audacity, but it's really not suitable, not at all. You absolutely must go through the mapping stage of your cutting head; it's truly essential for making progress! Sincerely, Sébastien Hi! thanks for this! so how ca...

Hey trolls, So instead of randomly tweaking angle / pressure / springs / vibes / magic and hoping for the best, I started writing a small Python tool to actually measure what my embossing head is doing. Current setup: DIY embossing head, cutting polycarbonate (CDs). Yes, I know. Don’t judge me. What...

Hello, The V-spring is meant to restrict the movement of the torque tube only in the direction that the coils push and pull, preventing it from twisting. Regarding stiffness, you have to consider the overall stiffness of the system (coil support and V-spring), which will determine the resonance of ...

Hello! I’m currently working on a DIY embossing cutterhead. After researching extensively on this forum and using every AI tool I could, I managed to gather enough information to start building one. I’m now on my third prototype, but I’ve run into some issues: I’m getting a complete loss of definiti...

Hey firstly, nice build. 3D printed parts can be a bit different to work with but keep going!... Hi Magician! First of all, apologies for not replying earlier — I haven’t used the forum in quite a while. I took note of your feedback and spent some time working on the design of the embossing cutterh...

Hi diy_cutter,I really appreciate the work you do. I follow you on Instagram and wanted to know your opinion about my machine and if you could give me any advice.

So far, this is everything I’ve got. I would truly appreciate any help you can offer. My goal is to eventually open a local service in my city to cut records for small bands that can’t afford a big-budget recording.

This is the amplifier I’m using, and for the audio source, I’m using my PC with Audacity. All I do is take a sample song, apply the ‘RIAA’ curve and then invert it. I’m not sure if that’s the correct approach.

Here you can see it recording—or rather destroying—an acrylic disc, haha. I also included a picture of a commercial vinyl record to compare the difference in groove quality.

This is an earlier version of the head. I managed to get it working, but the results weren’t great, and the torque tube was damaging my needle. I'm currently using a commercial sapphire stylus. I also have a homemade stylus made from a tungsten carbide electrode.

I placed a hollow cylinder filled with small lead balls in the counterweight, since the head is quite heavy due to the speakers.

This is the head—this is where I need every bit of advice and assistance I can get. I’ve managed to make a few recordings, but they suffer from low volume and poor sound clarity. Everything is 3D-printed, and I’m using vibration speakers.

this is the machine and it´s control board, its just an start stop, left right, and a pot to control the speed of the steeper motor that moves the head

Hello everyone! My name is Franco and I’m from Argentina. I’m opening this thread to document the design and construction from-scratch of my embossing lathe recorder. I’ll be sharing my progress here. any advice is more than welcome—since I’m new to this, all I’ve done so far is based on information...

Hello everyone I am building a vinyl lathe recorder (Embossing) from scratch as a diy project, and although I have gathered quite a bit of information, I still have several questions. I would appreciate any advice or suggestions regarding the following points: Topic 1: Design and Parameters of Need...

Hello, how are you? Greetings from Argentina! Great job on your work! I also added you on Instagram. I'm currently building my own machine for personal use, and your posts have been very helpful! I'm dealing with some issues at the moment, but I'm slowly solving everything. I wanted to ask you about...

Hello fanelx, For a complete novice, you've already understood a lot. The head looks very good at first glance and contains all the necessary elements for pressing. The biggest difference between cutting and embedding is that in the first case a sharp V-shaped tip cuts material out of the surface. ...

I'm leaving you with images of the head I built. Any recommendations for modifications are extremely welcome.
