What are these ?

[benchmark]

These items came with my used Lathe/mill when i bought it , i would like to know what the 2 items circled in red are and what are they used for?

Thanks.

I'll give you a couarse description.

The one on the left is called a drift. It's used to knock two morse taper sleeves apart or get the drill chuck out of the drill. The second looks like a division wheel that can be attached to the back of the lathe spindle to help index the part.

Anybody care to clarifiy these items more.

Bernd


Correction made to my spelling. Sheessh. Corrected again because I didn't know my left from my right.

I cant tell if the round object has teeth (as in a gear)? If it has, I would have thought that the arm on the right would attach to the lathe, the gear object to the spindle (most likely at the outboard side of the headstock) and together they would make a dividing system for marking/filing/drilling/making a keyway/ect ect ect.


I could be very very wrong ( I am due   ) I'm sure others will chime in with greater wisdom than mine.

Edit, someone already did.

The one on the right is called a drift.

The one on the LEFT is called a drift.  Funny, Bernd.  ; )

Kenneth, the wheel looks very much like a degree wheel for a VW engine.  Whatever it is, it would do fine for simple dividing jobs
on the lathe.  It says EMCO on it, so was probably for a Compact 5 or Compact 8 Emco lathe.

Benchmark - hehe, I got a drift in my box of "stuff" with my lathe a few years back and it was chucked in a box for ages. It was only about 6 months ago I figured out what it was for!

The main reason I`m replying is because I use to own a EMCO Unimat 3 lathe and I think the other part is the dividing fixture with one of the dividing plates attached! The plate should come off the main fixture and can be replaced with other wheels that can be purchased:



I never had one and always fancied buying one. I`m pretty sure that is what it is.

I'll give you a couarse description.

Were you looking at the picture upside down or did someone exchange my left hand for another right?

At first I just thought that you spelt left wrong but now ....

I wuz here, just after Bernd replied. Left/ right, err...... 

Too complicated for me! I've come back later......

Thank you for the input guys from your replys and then i googled the names you called them, its confirmed that the first is a Drift and the second one is a Divider like you correctly say.

Does anyone have a little video or demonstration on how both are used?

[Bernd]

I'd give you a little demo, but I'm afraid that with my spelling I would probably hit my hand. 

I'll take a quick pic and post it in a few minutes, Hang on.

Bernd

[Bernd]

Ok, got some pics.

The first shows two Morse taper shanks with "tangs" on the end.



Next is a pic of a drill spindle. Usally you'll find an oval hole such as shown. When the taper shank is "tapped" in to hold a drill or drill chuck the tang will show in this "window" like the pic shows.



When you want to remove the drill or drill chuck. Place the "drift" (and I can never remember if the taper goes down or up, works either way) in the hole and hit with hammer or some such thing. The arbor will drop out. Make sure you either catch it or place a piece of wood on the drill table if the tool has a sharp point. DO NOT USE your hand to catch the drill.



I made my drift from a piece of cold rolled steel and just cut a very slight angle on it. Works just fine. I hope you get the picture of how it works.

(Hey Don, How was my spelling this time?    No left or right to remember)

Thank you Berd for that very clear illustration. i now see how the Drift is used. Which not makes me wonder why it was included in the first place as my lathe/mill dont have any drill spindle holes. All drill spindles are operated with a chuck key and even my tailstock is self ejecting. Curious thing that it followed in the box with the sale, i guess the previous owner just put it there.

[raynerd]

Is your lathe an EMCO ?

Does the dividing head some how fit at the back of the spindle head, I have actually seen a Unimat 3 with one fitting when I visited a clockmaker using one about 10 years ago when I had mine. I just can`t for the life of my remember exactly how it fits!!

Bernd

Sure looks like you got it all straight now. On top of all that everyone else should know what the Drift is for and how to use it. 
I wonder, is that a right hand or left hand Drift?

Will you be sending him for a long stand, Don? 

Or, a short stay......

Alright, I'm packing up my lathe and mill and going home. If nobody wants to play nice I'm just gonna' leave.

                                                                                                                                    

Don I think he's sending me for a long stand.

Actually Mister Squire it's both. It all depends on what side you stick the drift in.        (_{some how that didn't sound right})

Guess I better watch it or someone will tell me where to stick the Drift. 

Now to get back  on topic. 

Every time that I heard about or see a Drift it reminds me of how I got my last Drill Press free. A neighbour of my son had a drill press where he worked that they were going to throw out because they had gotten a new one. It seems that on the drive spindle the nut that holds the pulley on had come off and they could not get it back on because of the threads being buggered. He knew that I was setting up a shop so asked if I wanted it as he was going to throw it in the dumpster. I said yes, I would take it and possibly I could fix it.

When I got it home to my shop I had a look at it. There was a chain fastened to the drill with both the chuck key and a drift fastened to the end. It had a good spring loaded chuck key so that was a plus. I opened the top of the drill where the pulleys are and there lay the nut to hold the pulley to the shaft. I tried to screw it on but it wouldn't start. I finally got a stool to stand on to better see what I was working on and had a good look at the threads on the spindle. Nothing wrong with them, they looked perfect as did the threads in the nut. Finally it hit me, this was a left hand thread. Tried it again the proper way and it fit right on. Grabbed a wrench and snugged it up and never another problem from it.

Hi Guys,
With all this jocularity about left and right, for those who don't know there is an up and down side to the drift. If you look carefully at the drift taper, one side is curved and the other is flat. The slot where you put the drift has curved ends, guess which way round the drift goes?
If it comes across that someone is a know-it-all, apologies, but if the above helps someone that is all that matters to me.
Ned

[Bernd]

Thanks Ned,

I think we've got the full info on what it is and how to use it.

I could never figure out which was up with that thing. As long as it worked I was happy. 

Bernd

[Ned Ludd]

And quite right, too.

Hi "benchmark", very often it is necessary to employ MT reducer(s) in order to use tools that do not have the same MT as your headstock/tailstock. This drift comes in handy when removing said tools from a reducer.
