Hi Guys!
The story of the "from screatch" is continuing. Now the mechanical parts of my machine became ready. The next (current) step was the fabrication of the pulleys and their belts.Now I did made the advance driving stepper motor's springy-elastic suspension mecahnism wich is also makes possible the belt's tension adjusting via the sliding the stepper motor assembly back and forth.
The other step in progress is the creating the switchboard. It is not wired yet.
Let's see some pictures about the details and also a video about the ADR 2021
The switchboard:
The machine with its lifted baseplate for servicing:
The stepper motor with its elasticall suspension to prevent noise problem:
Advance stepper motor now in its place:
Lastly here is the video about the working mechanics of ADR 2021:
Happy summer and holyday for everybody!

Re: From scratch
Hi lathetrolls!
The story of my "from scratch machine" is continuing.
Now the last part is being fabricated. This is the cutterhead.
The active elements are two surface transducer speakers of 30w each.
The head structure is standard stereo one with 45-45 grade channels.
Here are the first steps-the framework...
Coming soon....
Good night!

Re: From scratch
Hi Guys!
The new that I did "sucked" with the stereo cutterhead. I made some design mistakes,so the ready made head did not fit to its place on the head advancing mechanism. So the mistakes are fighting back! Everytime!
Now I did begun to create a mono cutterhead. It seems that the previously purchased 30W transducers could fit... Lets hope the best!

Re: From scratch
Hi guys!
As I told that I did sucked with the stereo cutterhead I diecided to make a mono one. (Lets try once more with stereo a bit later)
Now I provide new photos. (below the text)
On the first you can see the preassembled mono cotterhead. It is similar (in shape) to the gamophone heads
The second picture shows all the parts of it.
The third one is shows the most precision made part- the "sound-swingarm". It is made with "pinpoint bearing" to provide precise movement and less friction. All of its parts mad of solid aluminium and brass by hand tools. ( Under magnifying glass)
This assembly holds also the cutter needle. It is held in place not with screw but with superglue. Maybe it sounds crazy but it has minimal added moving weight. The superglue is soluble with acetone so the needle can be changed easyly.
Have a nice day! See the pictures!

Re: From scratch
Hi Guys!
My ADR 2021 became ready ! It works,but I did faced with a great problem. This is the great surface noise wich is covers the recorded audio signal. I use the HSS stylus ( made from a 2 mm HSS drill bit) and polycarbonate blank. I did tried to cut and emboss too but without any success! Péease give me some advice!
Thanks! Gabriel

Re: From scratch
Hi,
Embossing would be your best bet if you are going with a home made stylus. You should be able to grind a conical tip that will work for embossing if you get a good mirror finish and the right cone angles on the stylus tip. You will need to experiment with the downward force and the head angle to optimize for the material you are embossing. If you can afford it, I would try and purchase an embossing stylus from Mike at https://www.recordlatheparts.com/ They work great, have a long life, and will eliminate that item as a variable as you dial in your lathe. There are some other sources that you can find here on the forum as well and all will work out of the box. One other option would be to buy a used dull ruby cutting stylus and run it backwards. This was a old trick that was in use prior to the availability of purpose made styli for embossing.

Re: From scratch
Hi Mark!
Many thanks for your advices!
Please tell me where to search(within the lathetrolls.com) about the dimensions and grinding methods of the embossing styli?
Bye! and Merry Xmas!

Hi Lathetrolls!
Happy New Year for everybody!
I did paused my progress when faced with the high level surface noise problem. This noise did covered my recorded sound
Tried to heat whole disc with infrared lamp- Failure
Tried to use WD 40 as lubricant-Failure.
Tried to change the embossing angle-Also failure.
Now I try to use the heated stylus- as Rek-O-Kut described this:"Thermo Stylus"
The nichrome wire is 0.1 mm thick. It is hard to see so I used magnifying glass.
The glue wich is holds the wire wrapped around the needle is a heat resistant silicone,used in automotive industry as cylinder head sealant.
My results now:the wire is succesfully held in place
The stylus become hot enough to make a smooth shiny based groove on the test piece of plastic.
The heating reached the correct temp. after 20 seconds
Lifetime of this experimental heated stylus was measured for 3 hours continous operation and it did not worn out.
Current during heat is 350 miliamperes.
Now I fabricate the heating transformer and install the Hot Stylus on my cutterhead. These works are waiting for me.
Here are few pictures:
Nichrome wire is glowing:
The BISON automotive silicone. Heat resistant to 300 Celsius:
Here is the experimental and successful Hot Stylus:
Have a nice day!

Re: From scratch
Hi Guys!
So long I did not wrote anything here. There was some sad- unpleasant intermezzos. I did divorced now,and this made me a little disturbed.
So now the heating power supply of my ADR2021 became ready. It works with a transistor 2N3055 wich is intended for the regulation of the current for the stylus-heating nichrome wire.
There is also installed a "continuity tester LED" to examine the state of the heating wire during work.
Have a nice day!

Re: From scratch
Hello, friend!
I've come all this way and just now found this community.
I made all the same mistakes. The only difference is that I haven't tried heating the cutter yet.
I started with a stereo head and later converted it to mono.

Re: From scratch
great work fonogabor keep it up
and Sharapov great lathe too you should open up your own thread on here

Re: From scratch
Hi Lathetrolls!
So the first recording attempt with the ADR 2021 was a totally failure due to the high level of surface noise.
I decided to modify the system and install a heated stylus to eliminate or decrease the the noise.
A regulated adjustable heating power supply was fabricated (using a simple 2N 3055 transistor circuit for adjusting the heating voltage)
Modified the cutterhead and installed a nichrome wire connector equipment,wich is wired to the head's main connector where is also a connection to the cutting amplifier.
Now a first Thermo Stylus is made.
This is a 2 mm HSS materiel wich is grinded for embossing.
Firstly I did wrapped a little piece of plumber's teflon tape as a basic isolation. It is glued to the steel with a bit of superglue.
Then wrapped 3 turns of nichrome wire and secured it also with superglue.
When it was cured I covered this area with some high temperature automotive silicone.... Now it is setting for a day.
LETS HOPE THE BEST!
Some pictures:

Have a great day!
