View Full Version : L-W Indexing head help....

Here's another 'freebie' I was able to get, a L-W indexing head! But it had been sitting unused for decades, and looked like it had been sitting in a very dirty environment during that time. It was filthy on the outside, and the grease on the inside had hardened solid. I spent about 7 hours completely disassembling every bolt, screw, gear, etc.

Cleaned, lubricated and greased, and now it operates like butter!

I see there are big threads on the left side of the head under the plastic ring:

After looking around for this unit on the net, I'm assuming that a chuck mounts on those threads, similar to this:

I only got the head, no chuck or tailstock with it. Is that chuck a specialty type of thing from LW? Or is there a current chuck out there that will work?

Wow, great score!

Excellent score.

BTW looks like it may take either a chuck or a collet (5C?)

As to the threads, you should be able to measure the major diameter and the TPI to determine what you need in the way of a chuck.

Great score indeed! Even better was this Yuasa rotary table, again for FREE!

But when I got it, it looked like it had sat in a barn for 10yrs. I spent hours taking it alllllll apart for a full and thorough cleaning. But after the time spent, the thing works like silk now! It's in nice shape too, a few drill marks in the table, but overall it is quite nice. For the price I can't complain..... ;)

As far as the LW head goes, there is a draw bar on the opposite side for 5C collets. And in other pics I've seen of this LW head, the chuck must just screw on the threads. The major dia is 2-1/4", but the pitch is 10tpi. I see 8tpi threads for that diameter, but 10tpi?

Is that normal?

I'm a newb at most of this, so I really appreciate the help.

Are you sure it's not 2-3/16 x 10? That's what a Hardinge lathe spindle nose is. I had a 5C lever collet indexer with that thread too. You can get a generic adjustable height tailstock from most tool houses.

Here's an ebay auction that shows me the stuff I'm missing, good pics in this posting:

http://cgi.ebay.com/11-L-W-DIVIDING-HEAD-TAILSTOCK-3-JAW-CENTER-DOG-CHART_W0QQitemZ370359542599QQcategoryZ41943QQcmdZV iewItemQQ_trksidZp3286.m7QQ_trkparmsZalgo%3DLVI%26 itu%3DUCI%26otn%3D3%26po%3DLVI%26ps%3D63%26clkid%3 D6175830830142235586

I was wondering if the chuck itself was threaded, but from this auction it looks like there's an adapter plate on the back of the chuck?

And it looks like there's some other attachment that can screw onto those threads too. Look at the pics in this auction:

I'd love to get the correct tail stock for this unit too.....

This is actually a very dangerous piece of equipment and should only be operated by someone with years of experience. Build a strong wooden crate and very carefully place it in the crate bolting/screwing it in place to keep it from shifting.

PM me and I'll give you my mailing address so I can take this very dangerous object off your hands. :D

This is a Chinese dividing head but it will give you an idea of what accessories there are for many or most dividing heads:

Keep an eye out on ebay for a foot stock or a tail stock. I searched both of those terms for about 2 months until I found my foot stock. I think I paid $25 for it and shipping?

Good score by the way.

The threads are about as 2.250" as you can get....

And here I have the jaws set at 0.500", and I count 5 threads per half inch, so this is 2-1/4" 10tpi?

Or am I missing somthing?

That will be a 2-1/4 - 10. You will probably have to get a blank backplate and bore and thread it yourself, then make it a faceplate or attach a chuck. If the inside part is for a 5C collet, you can also use 5C collet 3 and 4 jaw chucks.

Not sure I'm confident enough in my threading abilities just yet to pull that off....

the 5C collet-to-chuck adapter is a possibility, but would rather be able to use a 6" or 8" chuck on there with the hefty threads for support.

The L-W Chuck dividing head I have came with a faceplate
and as it uses a standard thread, I often put a 3 jaw chuck
from a southbend lathe on it.

Ditto for mine, I actually got a chuck with it.

The O.P's unit is bigger, mine is a 6" swing, and takes a 1 1/2-8 chuck or other accessory. It has a B&S 9 taper, but I have a center, a 3-C collet adapter, and an MT2 adapter to fit, so it works for me..

Looks like you need a tailstock for it so you can begin cutting gears etc. Actually you don't HAVE to have a tailstock, but it allows using regular tapered mandrels to hold the work.

BTW, you don't need *confidence* in your threading ability, you need to get *experience* doing it. That you get by actually threading stuff. Thread work on the lathe even if you "could" use a die. Have at it. This is a perfect opportunity

Where are you? Maybe someone on the forum could come by to help.

I live in SE Wisconsin, but our little shop we put together at work is in Illinois.

Now that I think of it, would this L-W head use 5C collets or some other external thread collet?

I fully agree. The lathe we have is new to me, so I'm learning as I go. I need some internal thread cutting tools before I can tinker too much.
And to start reading up on thread cutting in general. I've tried some external threads on aluminum, but nothing on steel yet. We don't have much steel stock in the shop yet, but plenty of aluminum.

When we got the green light to upgrade our mill from the crappy column mill/drill to something better, the budget allowed me to add in a cheap lathe. Before this we had no lathe, so I was able to at least get a Grizzly G4003G. Not the greatest, but perfect to learn on and WAY better than nothing at all. So I'm getting approval for some tooling here and there.

From the little bit of the inside of the spindle I can see it looks like it takes 5C collets. If you take a look at pictures of Royal brand collet closers you should be able to design a draw tube that would work with the indexing head.

As to threading, there are lots of threading videos on You Tube that will help. I also recommend buying a copy of the South Bend "How to Run a Lathe" book. I've been told reprints are available from Lindsey's Technical Books.

There is a draw tube on the opposite side of the L-W head I have. :)

I have ordered the South Bend lathe book. $10 to my door.

thanks!

The draw tube makes things easy and that is the best $10 you'll ever spend.
