4 jaw chuck for a Proxxon lathe??

[md1400cs]

Hi mates,

 

Have been looking for a self centering 4 jaw chuck for my small DB-250 lathe. I have their annoying non self-centering plastic one.

Their 3 jaw metal one is great!!

 

I did find a self-centering one for their PD 400 lathe. But that goes for around $400. USD – yikes – might not even work on their small DB-250 lathe?

 

Many generic 4 jaw types are available on eBay but who knows if they would screw properly for use with the DB-250??

 

Has anyone found one that would work?  Any thoughts are appreciated.

 

Thanks in advance.

What is the mounting thread?

I believe that the DB 200 takes a 12 x 1 mm metric thread.

Correct, the Unimat DB/SL does and some Sherline models also used that thread. I don't know about Proxxon threads but have never heard of the chucks being compatible with any Unimat models.

The current Unimat production (which in reality is nothing to do with the originals) also have a M12 x 1 thread. Beware, some of the chucks from this range are plastic.

Check Sherline,  they have a 4 jaw self centering with  that thread  $162.00

thanks for your posts,

Just checked the Proxxon website and these are the data for the 3 jaw metal chuck;

 

Three jaw chuck for the lathe DB 250
Used for concentric clamping. Made from steel and offering 1/16" - 1 13/32" (1.5 to 32mm) and 1/2" - 2 14/32" (12 to 65mm) when reversing the jaws. The chuck has a M16 x 1 thread for fitting directly to the DB 250 headstock spindle

 

So I need 16mmx1mm  for thead?? - looked at the chuck did appear to be 15mm+- and 1mm threads.  will check with  Sherline thanks!!

Hi Jimbyr,

 

Looked on their site - no luck

I then spoke with them - they told me that they don't make any chuck with 16m - largest is 14m - Hmmm

But thanks anyway. I'll keep using the Proxxon plastic one
