The Secret Society of Lathe Trolls

I totally agree with all your comments - fortunately I don't make a living from cutting! There definitely needs to be competition in the Dub manufacture business, If Appollo for some reason went down the pan ? What then for the busy mastering houses? I know there would still be MDC but they appear d...

I have enjoyed your posts & I hope you can return to this crazy world of cutting soon,
Good luck for the future.

A thing of beauty.......... Any idea what the finished head mass will be? I basic drawing with the general geometry would be very useful so that potential customers can evaluate if this can be mounted on a specific lathe such as 1) Size & position of mounting screws, 2) Position of stylus from rear ...

Regarding the calibration of your microscope perhaps placing a a standard vinyl disk (of the same rpm )under the scope would give you a reasonable idea of the divisions on your scope?

Sounding very very good to my ears... well done and please keep us posted

They look good and not easy to do......I have tried.....keep us posted
I take it that is the D1 ? (BBC/Grampian)?

My guess the answer is springs! the ones that centralise the two parts of the driver and return it to its "normal" position ready for the next signal ie like the one on the surface transducers currently being discussed on the forum......... :wink: But I can't imagine how these could be plastic? Sure...

Hi Bryan yes piano wire for torque tube and the soldered links to drivers the chrome tubes are from pen tops (actually propelling pencils)made from very thin brass then they are glued to the plastic discs (they look like brass) that are in turn epoxied to the driver cones, To facilitate alignment I ...

Photos as mentioned on my previous post......

Bryan you appear to be following a similar path to my own experiments ie. Alignment of coils within the driver etc the low temp aluminium weld looks interesting my torque tube is made from brass so that I can solder items to it, The drivers you found are very tough (I am now using the same) if you l...

Bryan I reckon the stylus holder/torque tube is the most difficult part of a DIY cutter head and I guess you would agree! You need to bring together 4 different elements :- Stylus, 2 x driver links, torque tube support, Stylus screw, And all need to be done accurately and yet still allow free moveme...

The saddle coil in the picture is one I have wound myself using a small winding jig I made it's a very simple set up that can likely be improved greatly but I could find nothing relating to saddle coil formers? The coils I have made are for my BSR cutter heads but it would be interesting to see a sa...

Them coils are looking great....
BTW hopefully I have attached a picture of a saddle coil

Looking Good Bryan thanks for posting this, I have now recieved a few of these same drivers and they appear pretty robust & I intend using them soon on my D.I.Y. attempt!
Great thread this along with Opcode's blade runner - keep it comin guys........

Well I guess I need to appoligise for asking what I thought was a reasonable question......
Let me get this correct if someone does not understand electronics they should not buy a Carruso head ?

Thanks for your reply, the only problem I see is that doesn't look anything like the one shown on the vinylike site so will it work ok?...........

Hello,
Can any trolls recommend a suitable power supply to run the Caruso RIAA pre-amp (version 1.1) ?
I have noted the voltage required from the Vinylike site and I built the unit some months back but have so far been unable to locate a suitable (+/-) power supply.
Has anyone else built one?

Have you attempted Saddle Coils yet?

Bryan that looks great love the idea of off the shelf drivers, Do you mind me asking for details of the drivers? I am midway through a DIY head build but have found it difficult to locate drivers of the correct rating and size & they look just perfect .....I am not planning to include feedback at th...

I would like to buy a Microscope for my lathe,
I understand x40 magnification to be the required amount,
Not too bothered about a stand or arm has I am sure I can put together something suitable,
But require the lenses & focusing mechanism to be in good shape.
Any help appreciated.
Thank you
