The Secret Society of Lathe Trolls

Happy weekend for everybody! So I am here! My record cutter machine- ADR2021 now will get its housing. It made of plywood and some small metal parts are used.(handle,edge reinforcement,hinges,leveling legs etc...) On these pictures you can see some woodworking of the housing and also an invention wi...

Hi Constatin! I did listened your recordings.... and I got an idea: Your sound is a little "boxy" and lack of highs.... Did you applied the RIAA correction? When you are recording: Anti RIAA- this is empasizes highs and cuts the lows. When you are playing back: RIAA this is emphasizes lows and cuts ...

Hi Constantin! Please give me some information: How many milimeters is the OVERALL LONGITUDINAL length of your cutterhead? In other words: how many milimeters from the base ( where it is assembled to the advance mechanism) to the end . I am now choosing the place of the "bridge" of my machine. I wou...

Dear Friend!

See my project! Maybe you could get some ideas and tips.

Hi Guys!

A question: Could somebody to sell me a mono cutterhead from European Union?

Have a nice day!

Good evening Trolls! Now here are more 2 photos about the progress. (My building machine got its name: ADR 2021= Analog Disc Recorder 2020-2021) The baseplate of my machine is made of 10 mm thick aluminium. I had a 6 mm- thick steel plate but it is too heavy-so the final weight of the apparatus woul...

Good Evening for everybody!

Here are some photos about the working main motor assembly of my (under construction) record cutter machine,

Hi guys!

Here is some more photos about the progress of main motor assembly. The intermediate axle and the pullwy is not fabricated yet..

Have great day!
.

Hi Guys! Happy New Year! So more pictures about tha main motor assembly. The structure is welded together. I do not like to weld but sometimes it is unavoidable. The other picture is the drawed plan of the platter driving mechanism in side view. The motor, the intermediate drive and the platter. 202...

Hi Constantin! Sorry but I cannot to give to you correct answer about the ideal weight for the recording. My lathe is in the " under construction" status. BUT! I recommend for you two approaches wich are can I summarize in two sentences: 1/: Do not change the content of your victorious team! (If som...

Hi Constantin! Some thoughts about your issue.... Personally I am building my lathe from scratch.. It is another way.... As you did wrote you did not used any method to soften the surface of your disc. Try it- I recommend. Because for example some industrial lathes are using "thermo stylus" wich is ...

Hi Guys! First of all I wish for you the Merry Christmas! Now I did begun to construct the main motor assembly for my recording machine. Here are some pictures. Before the pictures here is a riddle: I do not have a rpm. measuring tool- but I correctly measured the speed of my future main motor ( it ...

Hi Guys! Today was arrived the most important part of my lathe: the main motor. In previous post I did wrote that the idea with a stepper motor became wrong. The stepper ran with the noise similar to an old trolleybus. It is new as its driver too..Its maximal RPM was only 122 wihch is less than nece...

Hi Guys! Could somebody give me some advices? The talking about the platter motor. I did obtained a bipolar stepper motor of 3.1 Nm Torque. Its driver is a DM556D. The PSU -as I shown.... on photos. The software was written to Arduino. Everithing is fine but the noise of my motor is similar to a tro...

Hello friends I am was far for a little long time! On summer here was some home improvements. In my house an old window was changed to new and another was withrawn. Painting,cleaning and so on,,, Also in summer we adopted a nice "four legged girl" from a dog asylum. So this summer was crowded with e...

Today are arrived the parts to platter driving motor....These are: a Nema23 stepper motor,a microstep driver module of 4A power and a toroidal transformer. Now I am working on the 2 channel power supply of motor controllers.... Pictures are coming...Soon...

Dear Mark! Thank you very much for your help. I did switched from this asynchronic AC induction motor to the microstep driven stepper(NEMA 23 and a driver). This device was used in the DIY lathes by some people here in "lathetrolls.com". Because the stepper motor is acts here as a synchronous one it...

Hi Markrob! I am always wellcome any advice or recommendation! The motor noise I did measured with an Android app. on my phone. The motor was lying on my work table with some damping material under it.. This motor was out of the future equipment-so not mounted in,. This damping was intended to simul...

Hello Guys! Now during creation of my " from scratch lathe" I did faced with a problem. I would be glad if somebody could give me some advice. In my project the next step is the main (platter) motor assembly. BUT! I cannot to obtain one. The ideal candidate must be: 80-100W power Quiet Rotating cloc...
