The Secret Society of Lathe Trolls

I'm thinking that the Lord of the Bass option might be the one as it can be thinned with MEK.

I think many people ...

I'm glad people follow my work. Since this forum thread is about diamond machining and not lathes, I'll keep it short. I spent several years developing and refining the lathe you're talking about. A huge amount of money was spent making it profitable. I cannot give you the work of several years of ...

Is there actually a way of forming such a small radius on the tip of the diamond?

Hi, I just saw that you have been experimenting with sapphires. Here is a source of synthetic sapphire which may be of interest

Quite reasonably priced, though from memory the shipping was a bit expensive. Still reasonable though

What is an H9 head? Who makes those?

Hi, Well done on your head design and construction. I've also built a head based on Grooveguy's design, I too found his descriptions of the project encouraging and inspiring. I don't think I would have attempted this otherwise. Here is a link to t thread about my cutting head if you are interested. ...

Here are my best recordings on a DVD using a head made from $5 speakers and pressed into polycarbonate:https:// www.youtube.com/watch?v=GKslFuQEWHM The second recording is using a professional NINGA head for $15,000, cutting a 12-inch copper record with a diamond knife:https: //www.youtube.com/watc...

I stopped worrying about knives with artificial diamonds, because CBN is easier to grind with diamond discs and practically lasts on copper for the same amount of time, but diamond is 100 times more expensive, so for experiments I buy such used CBN knives [they turn hardened steel] for $ 10 for 10 ...

I don’t think that heat would have been an issue given that the burnishing facet and cutting edges were done manually. I’ll keep this in mind though. I wonder if using water will produce a better mirror finish?

A quick photo showing both modulated and unmodulated grooves in the lacquer. You can see a lot of very fine scratches on the surface of the lacquer - it's an old one for experimenting. Still plays back reasonably. The grooves are probably a bit wide, around 3.8 mil. I set stylus weight to 25g so cou...

As a little aside from making diamond styli, I also had a go at making my own sapphire cutting styli a while back. I managed to find a source of sapphire rods which are about 0.7mm diameter. Since I'm starting with a rod, the first step was to create a flat mirror surface. I'm pretty sure I did this...

Brilliant answer! Thanks Estrada

I'll give it a try!

Good luck Phil, let us know if you have success

I'm interested to see what others have to say on this topic - I tried using ceramic bonded discs, but found the removal rate was too slow - or maybe I'm too impatient, as it seems like Estrada is getting usable results with a bit of patience... Hi I have a terribly simple question.... Using a facet...

I think there are many ways of approaching the cutting angles, but this is how I do it. I set up the my my faceting tool so that there is an angle of 40.89 degrees between the diamond and the scaife. This achieves a 90 degree tip with a back angle of 30 degrees. I worked backward from this to get th...

Welcome to the world of lathe cutting acemc. I can certainly send through some STL file for the 3D printed parts, you may need to modify them to fit your lathe once you've built this but it should be enough to get you going. I agree with Markrob's suggestion of going smaller rather than bigger with ...

Hi, are these still for sale?

Hi, I have one of these heads. I haven't had this issue but at one point I was looking to re-do this connection for some reason. I think I was getting a lot of distortion I couldn't explain and thought this might have been the problem, I think the problem ended up being a blown amp. In the end I lef...

Hello all, Just thought I'd share on a bit of progress with the cutting head. I had been struggling with distortion at higher volumes so I went back to basics and did another pink noise test and found that I had a resonant peak around the 5khz mark. I seemed to have missed this before, probably beca...
