Re: Heavy Ten conversion to L00

Hi There,

Despite anecdotal tales to the contrary, threaded chucks do
come loose.  This is especially true if one has an instant
reversing motor.

To reiterate, for the third time, all my other working lathes have
L00 spindles.  Rather than buying more chucks, I decided to
convert this Heavy Ten over to L00 for uniformity.  Also, this
particular Heavy Ten is a 10R (with the 1-7/8" spindle) and
there is something wrong with the threaded end of the spindle.
Tooling doesn't want to thread on.  Also, the smaller 1-7/8"
spindle cannot take 5C collets. They used the smaller 2A
collets (max size 11/16").  The L00 has the larger spindle
through hole and can accept 5C collets (hence 10L).

If you are happy with your threaded spindle, by all means
keep using them.  I've owned over a dozen lathes in my
life and most had threaded spindles.  After using the L00
spindle for the last 20 years, I have a preference for them.
Remember, I'm doing this to please me and I don't care if
you don't agree.  You be happy with your threaded spindle
and I'll be happy with my L00.  That's all that matters.

I do thank Dave for going to the trouble of making the measurement
and taking pictures so that my conversion went as smoothly
as it did.

Good Luck!

Interesting project. Wonder how you came up with the  idea to convert to a L00 spindle.

Why would one  waist all the this time to convert. I bean in machining over 50 years never had a chuck come of in reverse. Yes i machined in reverse many times never had a problem. The chuck was installed properly.

Thanks for the link Steve.  I've seen those drawings before.  But I don't understand why the photos show that hook that pivots.  If the L00 just has a nut that is turned onto the threaded part of the chuck to pull the chuck tightly onto the taper, what's the hook for?

Re: Heavy Ten conversion to L00

Hi There,

There have been several types of spindles developed to
mount tooling (chucks and faceplates) onto them.  The
earliest was the threaded type.  This type is straight
forward but has the disadvantage in that it can un-thread
if the spindle is rotated in the reverse direction.

To address this problem, there have been some different
spindle mounting systems, Type D - Camlock, Type A1 -
Short Taper, Type A2 - Short Taper and Type L - Long Taper.

Type D - Camlock seems to be the most popular of these
different types.  In my case, I own a couple other lathes
that have the Type L - Long Taper spindles.  In each type,
there are different sizes starting with L00 and go up to L3.

The chuck is drawn onto a large taper that centers the chuck
on the spindle and there is a longitudinal key that prevents the
chuck from slipping while on the spindle.  This allows the spindle
to turn in either direction without the risk of the chuck coming
loose.

Good Luck!

Hi Dave,

Thanks for the measurements!  I have the headstock
currently set-up on the mill  and I have been "eye-ballin'"
the placement of the fulcrum and pin from your pics.  I
figure that I will have the necessary holes drilled and tapped
later this evening.  I'll make the necessary adjustments to
my "eye-ball" set-up based on the information you supplied. 

Good Luck!

Re: Heavy Ten conversion to L00

Hi Webb,

I've attached a sketch showing the location of the 0.250 dia steel pin and the attach screw that has a head diameter of 0.500 inches. I tried to measure from known features to make it easier to interpret (see the photo for detail). Notice that when the hook is pushed back and away from the spindle it sits on the pin, with the bottom of it parallel to the bottom of the headstock.

The thickness of the shim between the headstock casting and the hook is 0.300 inches. The casting surface does not appear to be faced around the pin or the screw, but I was not able to remove the screw to perform a detailed inspection. I was going to do a nice SolidWorks sketch for you except I am having issues with my latest license not installing properly.

Let me know if you need additional measurements or if you need help interpreting my sketch.

Hi There,

I appreciate the responses so far.  Jim, I'll check out the video
later.  I am experienced with mounting L00 chucks.  I have a
11" Logan and two Clausings with L00 spindles.  I have a
significant number of chucks that are L00 for those lathes and
it would be convenient if the South Bend could use them too.
Plus, up grading from the 1-7/8" X 8 tpi spindle to the larger
L00 will give me 5C collet capability too.

David, when you have a chance, if you could get some
measurements of the location of the pivot screw,  I would greatly
appreciate it.  Also, the height of the spacer would be nice too. 
A while back, I picked up a NOS wedge kit that is for the 13" through
16" SBL's so the spacer is too tall and so is the pivot screw (but
once I know the correct spacer height, I can figure the correct
dimensions for the pivot screw). 

Thanks Again for the Help!

Re: Heavy Ten conversion to L00

I don't have time at the moment to give exact dimensions; I will get dimensions within a day or two. Here are two photos. My Heavy 10 is currently apart after having the bed and saddle machined and fitted. Notice the how the pin provides a stop in the open position.

I have the spindle and most of the parts I need but I need some

A couple of the questions I have are:
(1) Where is the location of the wedge pivot screw?
(2) What is the thickness of the spacer that goes under the wedge?
(3) Is the headstock casting spot faced under the spacer?

Thanks in Advance for any help anyone can provide.

Actually the “must report” number for banks is $10k. However, the teller has discretion and is allowed to rat you out to the feds for any amount. It happened to once when I wasn’t wearing my Sun. best. I closed my account.

Re: For Sale and Wanted items

Google will obviously give you more details, but you'll be happy to know that
laws and regulations currently in place require financial institutions like banks,
etc. to report transactions in excess of $10k.

If you go to a bank and take out $10k cash to say buy a car in a private sale,
the bank will fill out a suspcious activity report (SAR) and send it to the feds.
Same if you were to deposit that much cash. FWIW, I think it's acutally less than
that, because that's what my bank did when I took out $5k to buy a car.

Like it or not, Big Brother is watching.
