Re: SP10MKII Lathe
I plan to sell custom built lathes in the future (once I've shown my systems fully working), no heads, just mechanics and electronics etc. If you don't find a suitable product then I can supply to you...
Cheers

Re: SP10MKII Lathe
I'm confident your future customers will be very happy with your work, your machines are very aesthetically pleasing, presumably functionally proficient as well!
I'm itching to see photos of your other builds, please post some if you wish, I think its safe to say we all would love to see them!!

Sillitoe Studio Lathe
In its current state it weighs around 60kg and is 700mm long.
It has a brushless dc motor and lead screw setup mounted on the back.
It has a direct drive Baldor BSM90B- 3150AA brushless AC servo motor for the platter.
I'm waiting on some rubber vibration isolators to put in between the motor and shaft spacer.
The shaft that you can see in the photo is just there for reference and will be replaced with another shaft/ sub platter. It is attached to the motor with a flexible jaw coupling.
You can just see the edge of the tapered roller bearing at the base of the shaft (this is what the sub platter will sit on).
The suspension box is pretty hefty, haha.
Still working on the arm.
I will put my meters, electrics and controls into that stainless steel chassis at the right-front of the lathe.
I'm still looking into a few things, 16 inch vacuum platter (weighing around 15-18kg) and fluid coupling/ torque converter to dampen any vibrations.
I will probably have to go through a few variations of sub platters to accommodate different vibration dampers...
If you have one spare I'm chasing a NOS Lyrec or Neumann platter.

Re: Sillitoe Studio Lathe
Wow sillitoe you are very talented my friend good job This look very robust which motor use for the platter ?
Re: Sillitoe Studio Lathe
Cheers dimi! The platter motor is the black thing that's hanging out off the side of the bench with the wires coming out of it.
It's one of these, very powerful.

Re: Sillitoe Studio Lathe
The motor is now mounted with rubber vibration isolator fixings and there is absolutely no (perceived) vibration on the lathe or bench.

Re: Sillitoe Studio Lathe
Wow looks great nice progress
Re: Sillitoe Lathes
It's sitting on one of two boards that will become high powered LM3886TF mono blocks.
The other thing is a stage for the microscope.
I've been getting lots of positive feedback and interest in the SP10 lathes that I'm planning to sell.
Thank you everyone, it is very motivational
I've given myself a deadline of 6 months to be ready to start offering systems.
I can't give a realistic idea of price yet, I'm still adding to and refining the lathe design.
I'm working on lots of things including...
Much simpler chassis design to enable the user to easily mount their TT.
Bolt-on 14 inch vacuum platter for the SP10.
Pitch control, switchable between analog and software (pwm knob and Ableton/ arduino).
(I wonder how many styli I'm going to break while sorting out the depth servo haha).
Control panel with head position marker.
Microscope slide/ vacuum arm for platter.
Tonearm. I'll probably go for the 12" Jelco as used by Opcode66.
I'm also looking into using these motors as they're low profile, have loads of torque and are very precise. http://www.nsk.com/products/precisionmachine/megatorque/#tab2
I need to build the amps, preamps, mount for the head etc before I show my current system running but that should be fairly soon.

Re: Sillitoe Lathes
I'm really excited to see this lathe come to life.
really nice to see how this has come along well.

Re: Sillitoe Lathes
Good for you Sillitoe , great to see creators of lathe products to the market
Very exiting stuff ! I love the Caruso head very nice product

Little update...
I've found reliable sources for nearly every part of the production models of the SP10 lathe.
Here is a link to a good source of SP10s (among other goodies) if anyone is interested. http://www.hifido.co.jp/?lang=E&genre=0301&keyword=&arrival=10&limit=10&price=0
Videos coming soon

Re: Sillitoe Lathes
Thanks Sillitoe, far out a lot of good stuff on this website pricing is pretty good too.
Re: Sillitoe Lathes
awesome project! looks nice!
Re: Sillitoe Lathes
Here's a short video of the auto head drop and lift in my new head suspension design.
It will be much prettier soon!
The head is mounted via a locking torque hinge for easy angle adjustment.
The wooden part will be replaced with a nice aluminium bar with a heavy duty torque hinge built in, it will be very solid.
I haven't tightened the bush up too much yet but it all works fine for this demonstration.
The air dashpot allows for precision adjustment and dampens the bounce from the spring.
I haven't mounted the depth servo yet.
The rc plane retract is fairly loud but I can't feel any vibration from it in the whole assembly... Silent lead in and out grooves should remain silent... We shall see!
In the video I'm using a potentiometer to lower and lift the head, you can switch it to be automated it in the same way as my pitch control via the DAW, this will make locked grooves (and locked groove records) very easy.
Lots more to come.
Cheers James.

Re: Sillitoe Lathes
You may want to work on smoothing out the lowering of the head. If you come down too hard you will chip your stylus. That is very painful to the pocketbook when working in diamond.
FYI, on a Neumann suspension, this is performed entirely with a servo that a pivoting front panel is connected to. The cutterhead connects to the swiveling panel.

Hi Sillitoe
Nice work ! Is this lathe system fully automatic in the future ?

Re: Sillitoe Lathes
Na she'll be right fellas!
Haha, yes, there will be a concave ramp on the bar where the moving part of the retract unit contacts.
The moving part of the retract will loose contact with the bar at a later stage of the drop, this will smooth the drop.
The depth of the moving part of the retract is also finely adjustable. I'll find the sweet spot.
I can also lower the voltage that is going to the retract for slower movement.
Calibrating the depth servo is what really frightens me about ruining styli!
Got any oldies you don't need guys?
Cheers
