The Secret Society of Lathe Trolls

Few months ago i bought a stylus from Tasos . I used it on a 3d printed cutterhead designed by me inspired from Sourri's head . The sound is way better than the one i obtained with simple tungsten needles . I obtained on polycarbonate around 5-6 grooves / mm , 45 rpm , at a backward tilted angle of ...

Hi Gabor . I recently bought something like this and , after i tested , i can say it does a perfect job :) https://www.officedirect.ro/accesorii-pentru-birou/cuttere/cutter-compas-cu-6-lame-de-rezerva-si-2-mine-ecobra-770630?gclid=Cj0KCQjws-OEBhCkARIsAPhOkIbPY1NDJKH0iChuC9Szy7_MU1d6TYeEl9ZC9jMewZ5Ma...

Thanks Fela Borbone

Ok , thanks

Hi soeffingodly , sorry for the late reply . Now i work at another version of the lathe , stil embossing . Can you tell me what is the diameter of the needle in the mounting area ? Now i use a 1.6 mm needle but i can modify the needle holder .

Hi reservox , the rod , i used a carbon fiber one , is glued only on the tip of the cone , it goes about 5-6 mm inside the cone , it does't touch the membrane of the tweeter .

Some more tests , still problems above 10khz , probably the 3d printed parts are not rigid enough .

Was it heating first or lighter fluid ? ))))))) thanks again

Thanks soeffingoodly for the tip

For 7'' i use 1 mm and for 10'' i use 1.5 mm .

Hi , i have to dissapoint you but i'm a newbie too :) . I can only help you with informations about my project , on this forum are other users with infinite more knowledge than me . I use car tweeters Peiying PY T 59 , i emboss with a tungsten needle , first i used a cone shaped at 90' with 180 gram...

Hi , I attached here a compressed file with the stl.s and some photos of the embossing head , based on the one made by Souris . For connecting the cones with the needle support i used 1mm carbon fiber rods , also 1mm carbon fiber rods from the needle suport to the cilinders and for connecting the he...

Hi ilovedrums247 , yes the screw is M3 and the cutterhead can lose some weight . Mrd i still work on this project but when it will be ready probably i will upload the stl s on this site , if the moderators are ok with this . I continued to work on my recorder , embossing way and i made some improvem...

This is a movie a made last month . https://youtu.be/y_u7oGvssoA

The head is a copy of the one made by Souri , 3d printed and with car tweeters . Yes , i reversed the phase of one speaker . Also , if you find anything interesting in my project , ask . I can send you the .stl s .

Hi XRC , thanks for the tips . I noticed your work , with better results than mine and if it's ok with you , i'll ask some more advices . Thanks alot once again !

Hi Jesus , this way i obtained some results . I tryied to lighten up the weight at about 140 grams and to the end of the record , when playing , the needle didn't stayed in the groove . The tracking force of the turntables used for listening the recordings is around 3-3.5 grams , as i usualy use whe...

Hi Gabriel , sorry for the late reply . Check your FB messages

Hi Gabriel , Happy new year ! Sorry for the late reply . Yes , i make small increments adjustments untill i get better results and than i write the values in a notebook and make photos of the set up . Very primitive way but apparently it works :))) . You know what they say : if it's stupid but it wo...

Hi Gabriel , thanks for the response :) . Yes , i was considering the infrared lamp , actually now i design the stand for it . I saw that the recomended surface temperature is about 35'-45' C . Today or tomorrow i'll make some tests . Another thing that's still blurred for me is the embossing weight...
