Re: DC Motor for unimat SL
I use a 12v 120W motor for my SL and it's more powerful than the
original motor.
24v DC x 120W should be more than enough power, unless you're
really pushing the SL.

My question is would the 120W scooter motor do the job or do I

Re: Opinions Sought (Cross-Posted)
Gracias, Senora! Tried to do that on my phone, but kept getting error messages about too many words. Finally gave up. After about 2 minutes of troubles. I was having a rough night.
And the greeting used up most of my Spanish. Once upon a time I had more, but it seems to be evaporating out of my remaining brain tissue.

Re: Opinions Sought (Cross-Posted)
I think in a previous response I included the below link to a page of Unimat name plates from the Unimat section at lathes.co.uk.
If the subject is name plates, you might send them a good photo of yours, and of their lathe, so they can add it to their site.
On their home page near the bottom, is "Make Contact".
Also, if the question is about the name plate, could you provide a close up photo.
Creo que en una respuesta anterior inclu¨ª el siguiente enlace a una p¨¢gina de placas de identificaci¨®n de Unimat de la secci¨®n Unimat en lathes.co.uk.
Si el asunto son las placas de identificaci¨®n, puede enviarles una buena foto suya y de su torno, para que puedan agregarla a su sitio.
En su p¨¢gina de inicio, cerca de la parte inferior, est¨¢ "Hacer contacto".
Adem¨¢s, si la pregunta es sobre la placa de identificaci¨®n, ?podr¨ªa proporcionar una foto de primer plano?

Manel:
Does anagram mean name plate?? Here is a page at lathes.uk of name plates and I don't see yours.? I can't read it from your photos. It might have been private branded by a seller. ?Anagrama significa placa de identificaci¨®n?? Aqu¨ª hay una p¨¢gina en lathes.uk de placas de identificaci¨®n y no veo la tuya.?

Milling column drawing for Unimat SL
Hi everyone, I just bought one of these awesome little machines and I was wondering if there was a drawing for the milling column assembly for the emco unimat sl lathe. If I'm not mistaken it's the DB503 assembly.
Thank you for your help,
Csaba

Re: Headstock spindle spring
Well, I think Carl you are referring to lathe use. I don't use a quill spring on the Unimat I use as a lathe.
I have a separate one set up as a vertical drill press / mill. I think it would be a little awkward not having the quill spring on that machine.
Martin P.
P.S. David, to answer your other question, Emco added the quill spring probably very early 1960s. The 1963 Miniature Machining Techniques shows a quill spring in place on a cast-iron DB200. The first SL came out in 1965.

Hello
David:
My 1973
Unimat came with one, and it was the first thing I took off.
It is nice to have the spring return, but with the spring
there is only 19mm of stroke available. Take it off and you
have 25mm of stroke.
Just
use the quill lever to lift the spindle up and lock it there.

I suppose they are good when using it as a drill press.

That would be the Compact 5? A really nice machine. Like the Unimat 3 but a bigger work envelope.

Re: Tips on machining pulley grooves
Keith, I did have another idea¡ What I¡¯m trying to do is essentially cut an internal semi-circular (ball) shape but there is obviously no room to swing a cutter on a pivot at the edges (it would be on a ridiculously small scale anyway).
I wondered if a cutter held vertically with a simple lever to rotate it would work. Something like a cut-down, ground-down and re-shaped small boring bar (3/16 shank)?
The cutting surface would be greatly reduced, as would load on the drive train. A ¡®proper¡¯ cutter shape could be used to suit the material Arranging it could be quite simple, dropped through a block of half inch square stuff bolted into the top of the tool holder. Disc type stop with a grub screw against a flat. The issue I think would be killing excess wobble (and therefore chatter) while still allowing it to be rotated.
Feasible?

Re: Off Topic measuring units
I have 4" dial calipers in both systems; one has a white dial, the other black, for quick recognition.
Also a 6" with dual systems. Red pointer for inch, black for metric, or is it the other way around?
