The Secret Society of Lathe Trolls

Hi pentlandsound /David, First of all thanks so much for this thread, your instructions PDF, and for making the CAD files available. I don't think I'd even be attempting this if this great info wasn't out there! I have a question about the dashpot and damping side of your build. It seems to be the m...

We have made 16" in the past, it's a custom job but we have done it a few times. This is great to know - I may be back in touch assuming everything else progresses well! Head weight is just a rough guide, all that is important is groove depth. So feel free to set it by weight, but measure the groov...

The depth is set by you by adding more head weight Thanks for this - I had actually been looking at your store for stylii and blanks. Does your diamond stylii have a recommended weight to cut the 2 to 2.75mil width groove? Or does that depend on setup? I have heard of people using stylii weight of ...

Thanks for the reply, this is really super helpful! So you would just need to go a bit deeper. But as long as the playback stylus tracks, you are fine. Something around 5 mils should work. I actually found a great image which illustrates the different groove depths of various standard-groove 78" man...

Hi Mark, Thanks for your reply. I am glad that what I consider to be the hard part of the project you consider easier, and vice versa! The big question in my mind is how you intend to achieve sync with picture if the recording lathe is not directly geared to the film as was done back in the day. Tha...

Hi record lathe experts, I've always been a record fan (got my first record player when I was 7, at a jumble sale), and an enthusiast of various old/retro technology, but the world of lathe cutting records is new to me so I apologies for the silly questions - but I am keen to learn! My main interest...
