Thanks Steve...just put a cheque in the post!

Have just finished designing and making a cutter system using advance ball technique. It's for cutting wax cylinders and the photo and description is on the handcrankers forum (link below) Other flat disc cutter fans might be interested to see a home made cutter using advance ball for groove depth s...

Here's photo of my homemade cutter for Edison wax cylinders. It's an adapted Edison Ediphone dictaphone machine. An advance ball system is used to ensure constant depth of cut. First time I believe that the ball system has been used for cutting round phonograph cylinders. It's adjustment is the roun...

Just Goggle the name. Comes up No1 on Google .

[quote="tape"]A fantastic machine - instead of a pickup it has a photocell, upon which the grooves are projected trough a mirrorconstruction. No record or needle wear! quote] Not so. A 'jewel' tracks in the grooves so there is wear. See note 7 and NOTE at end of that page where there is reference to...

Heya, Took an Edison needle, ground a cutting face with my dremel, ground a couple of facets... and it carved its way through my first ever blank. Many many dB bellow the surface noise you could make out the song... if you were familiar with it to begin with. All of this blind... grind, look under ...

The high power is necessary because you have to accelerate the mass of the coil, coupler, torque tube, and stylus through the resistance of the cutting medium, and at high frequencies this takes a LOT of energy. Vincent Meyer I confess that I have never actually seen any good cutter heads but that ...

Thanks very much, cuttercollector, for your reply and taking the time to write all that explanation. Amazing to me that 500 watts (or more!) only moves a stylus such a small amount just because of neg feedback, but as you say, moving mass fast requires power. I am trying too to get more power into m...

Hello, I'm a new kid on this block. I am building a cutter head to cut Edison wax cylinders and progressing reasonably well using a 4 inch loudspeaker as the drive for the stylus. Have studied many interesting threads on this forum and also many web sites about cutter heads, I wonder if someone can ...
