PART IDENTICATION

[Marc Moreau]

I am working on the restoration of my Ultilathe LD 12 x 30, I find those 2 little parts ,to give you an idea beside, is a 1/4 inch bolt, if you know where they come from please let me know.

Hi Marc,

Where did you find the parts? They may be locating pins from the various things that bolt back onto your lathe - the gearbox housing, the feed and lead screw bearing?

There is not much data or pictures on the casing designs of the lathes - are they threaded in the back to allow withdraw? Sadly I am not home to have a look for you.

Marc, those are part of the D1-4 spindle nose. They have a spring in the back (it goes inside the hole) and the point engages in the locking cams to give a “unlocked” detent.

it is this part right here (in red)


this is from a SM 1340, but your 1220 Utilathe is the same. They prevent the cams from falling out, and provide the detent.

You should have three of them. I was missing some on mine and one was chewed up. So I just made three from mild steel.

Hi Robin,

That was my first thought but the pins look to only have a flat on the one side and the spindle nose pins show a flat on two sides - maybe an older design with just the one flat?

I only took my D1-3 collar apart once for a cleaning - didn't photo the event....oops

Part Number 24 ?

 

[Marc Moreau]

Just find it

Part Number 24 ?

yup.

It could be the difference between a D1-3 vs D1-4? One flat only vs 2. Not sure.
