help design cutting head

[mango]

Hello everyone , I introduce myself I'm a sound engineer and I wanted to start building my lathe to affect the plesiglas.
but first I wanted to see how well made and a thumb cut (I was thinking of using a plotter blade heated)

sorry for my bad English

[mango]

Ok thanks to this wonderful video I was able to understand how to behave the needle now I have to figure out how to build it.

Welcome! There are several examples of home-built stereo heads on the forums here. The most common way to construct one seems to be based on linking two small but powerful speakers to a torque bar which holds the cutting stylus.

You can follow the project of someone who clearly explains how to build it?
According to you it is more convegnente try to affect the plexiglass or buy vinyl virgins?
Where can I buy vinyl records?
Cutting tip that you advise me to use? I can use a blade plotter? a sewing needle? or should I buy one on purpose?
Sorry for the flood of questions, but right now I have the brain messed up

Angus McCarthy Thanks for the reply I'm sure you'll find in this forum everything I look for

[mango]

what kind of reels you advise me to use? low? med? hig? full reing? db? w?

hi mango

this is my first post, i have a vinylrecorder and it has tweeters on the cutterhead, maybe you can use tweeters?

dim

[mango]

It just dim but that response rates to? that voltage? and how much pressure he puts sound?

I think most posters on the forum here have dabbled in building their own cutting or embossing head at one point. My first experiments involved gluing a sewing needle to the face of a small tweeter and attempting to emboss onto plastic sheet. I was not very successful, but I learned a lot from the process.

Mango, the specifics of how you build it is up to you, depending on what parts you can find. I can say that you will want strong coils with decent wattage, not cheap little ones out of a set of computer speakers. You can see in the thread here: https://lathetrolls.com/viewtopic.php?f=15&t=2945&p=25322#p25322 that the Watts of the speakers and your amplifier should be somewhere in the 20-30 Watt range. There's a lot of other good information in that thread about embossing, which is probably the easiest way to start out with a home-built head and lathe. Actually cutting a groove involves different geometry and higher precision.

Plexiglass and blank PVC (vinyl) are not the best materials to cut or emboss directly. For experimenting with embossing, your best bet is to find a medium-soft plastic, since an embossing stylus literally presses a groove into the surface as it records. A lot of trolls have gotten good results by embossing with old gramophone needles. Others emboss using a plotter blade, or by flipping a cutting stylus backwards.

Ok I see to make do the best for the bur head, in any case, what do you think of the cut on polycarbonate?

[chaosbc]

It seems this is what most people use

[mango]

and do you think that has quality? if I wanted to affect my music to do a gig as a DJ would feel much background noise?

[tragwag]

poly has a noticeable amount of background noise in general.
The only way I could see a discerning DJ playing poly records is if they were cut on a Neumann system, like Todd (opcode66) does.
Check out www.deepgroovesmastering.com

That being said, I cut poly on a Presto 6N with fair results.
I wouldn't say DJ quality, as they are mono, with frequency response up to about 12 kHz depending on the source.
I can cut you a test if you'd like

[mango]

yes please do me a very big favor.
Meanwhile, I've got the blades for plotters and I'm abbozando a short head Shortly photos

Hello everyone after a period of abundant catch'm back with my wacky ideas and my lathe.
Since I started this work, I made ​​time to lose all the files made ​​up to now ...
one important thing and that I never said that the project is done entirely with the 3d printer, and I finally found a clever way to make the engraving head.

[chaosbc]

It looks rad !
I just wondered if there is any specific reason why you divided the head in three instead of making one whole part ?
