Hello there! Since i fell in this"lathe trap" i use my RekOKut Master Pro lathe for embossing and i am very happy about the reaults, BUT i am always looking to use my lathe in the way it was meant to be used..in other words i like to cut 16" acetates using sapphire stylus! All this time i look aroun...

..so what happened with this project?

Scammers have discovered lathes now too hey?...already very known in tapemachine world, i can smell them from miles away. Often on ebay the “seller is away”, if the listing is an auction it only runs for a day/max 3...if its a fixed price its always way too good to be true. They often have a pictur...

huge hand to Nick for supplying the lathe! honestly I just loved seeing it

If you like the Presto 8DG lathe and other Presto equipment you must see the "Great Balls of Fire" movie! There are scences that you will really enjoy watch over and over!

@basplin please note that this Time-Current chart is a generic for Fast Blow glass fuse and not for the ressetable one! You can just get and idea for the case you use a glass fuse! @markrob thanks for uploading this document, It lokks very interesting! As for my real time thermal measurement , i use...

500mA fast-blow fuse is a real safe value for the head and as long you cut with flat eq you will get loud cuts. But things change when you play with the eq and try to optimize the sound. When you boost the highs then the 500mA are not enough and you have to go up 1A but thats not good for the coils....

I supoose all these phone messages are all in MONO format. With a bandwidth of 300-5kHz you have plenty of options for the exact purpose. You can choose between older Prestos , RekOKuts etc and also the old Hara lathes! In my opinion Hara is the best option as they are all-in-one , small , portable ...

Just for reference , you can check the following link : http://www.etec.dk/ortofon-vintage.html.
There are nice manual that might be helpful for ortofon user!

Its been a year now and cannot be more happier with my official releases!!

increase of background noise on the inner groove

Sorry , i ment the "inner side of the groove"

...i already passed the 12 hours of embossing (!) and yes, still sound good, sound is still clear with no noticable distortion. I only noticed and increase of background noise on the inner groove , not that bad actually

..while working on my 5th release (12" vinyl - 45min total) . I thought i will check the lifespan of the stylus. Well i have passed 6 hours of embossing and frequency sound as good as it started. Background noise still the same low. I emboss a 2.5mil groove and the stylus is setted at 87°! ..so far ...

Hope that helps :

The fact that its fast, indicates that its not the motor as it would typically slow down with age as bearings gum up with dirt and age, increasing load.

This lathe originally runs @45rpm so when i run it at 60Hz , speed is lower than 45rpm.

Im not really sure but i i i did locked it to 33rpm when it was running @48Hz.
This mini lathe ment to be portable and thats the main reason i bought it. I'm planning to use it in places without the worry of carrying/missing an vfd.

I have the same problem with the idler wheel of its smaller brother (hara m180). I have send it to Jesus @agnewanalog for repair! I will let you know what about!

Why would you build a $3,000 machine and then use a $200 turntable? I don't know turntables very well but that doesn't look like the higher end models that most people use. Something similar happens with many VR T560 users. They spend lot of money buying a VR and they use a cheap TT which is not ca...

The motor is a sync 10V and is directly connected (through a switch) to the main transformer. Using a speedcontroller (vfd) i run the lathe at 50hz , then the speed is abit faster than 33rpm. When i run the lathe at 60hz then the speed is lower than 45rpm . Capstan looks ok , little dirt but not wor...
