Hi John,
A bit more sophisticated than my solution. I found that the cork from a sherry bottle (the type with a platic top/rim and a cork stopper) fits neatly without he need to do anyhing to it

PS The brass plug at the end of the quill is a dirt protector. It slips into the #2 Morse taper,also doubles up as a quick locator when I mount a chuck onto my mill circular table.again the table has a # 2 MT. The O ring locates into the the 20 mm hole in the chuck and I withdraw the plug upwards when the chuck is tightened up. it's within 1.5 mm concentricity.I use a dial indicator from there on if I need more accuracy.

Re: Tailstock DRO don't throw anything away.
thanks I will check out our local scrap man again I checked for Ali bar, ended up,with off cuts from engineers jobbing shops, stainless probably easy NZ being a marine area. brass very expensive here.

Re: Which lube do you use
Hi all,
Like Jim D, I use Tap Magic mostly Diluted 1:5 with
Kerosene (it is mentioned on the can that it can be diluted for recirculation
systems.) on my mini mill and sometimes for finishing cuts on the lathe. Only
time I use it neat is for tapping. Works for me and cuts costs a
tad.

听
Well I
finally got around to mounting the LMS 5 inch 4 jaw independent chuck on the
Micromark 7x16.
听
Here
are a couple of pictures:
<
>
<

My
first thoughts now that I have it are that maybe the 5 inch is a bit much for a
7x lathe. While the Micromark motor has no problem spinning it up, the added
mass of the 5 inch takes a while to spin down听to a stop.
听
The 5
inch weighs in around 14 pounds with the required听adapter
plate.
The
standard 3 inch weighs in at 3.25 pounds.
听
IT IS
POSSIBLE to extend the jaws out far enough so that they will hit the bed. A
little care will need to be taken so this does not happen. I opened it up so it
could hold a piece around 2.75 inch in diameter and the jaws had a comfortable
clearance over the bed. This was with the jaws in the position as in the photos,
I haven't turned the jaws around yet to take any measurements in that
configuration.
听
I'm
wondering now if maybe a 4 inch chuck would have been better.

On aluminum I have used WD-40 with success. Steel and cast iron I
use dark cutting oil the plumbers use for tapping. Usually nothing on brass
or bronze, though I have used cutting oil on bronze if I am boring or
drilling. I have had the occasion to turn copper,a couple of times.Real
pita, use milk or maybe paint thinner. I used paint thinner because I did
not have milk in the house.I tried several lubricants on copper before I got
satisfactory results with thinner.I use a brush ,mostly the acid brushes a
plumber uses for flux.听
Get a copy of "How To Run A Lathe" by South Bend.This is a paperback
book written years ago that still pertains to todays machines.
There is at least one online bookstore that sells the publication
,About $10.00. Lindsday Publications who 听has retired and no longer
sells books was the place to go.Anmother company is selling there
publications now,sorry I do not recall the name.I'm sure another post will
inform you,if not try googling "How To Run A Lathe".This is perfect for a
rookie machinist.听

Re: Digital linear scale for 7x lathe?
Hi John,
I was describing the "accepted conventional nomenclature for machine tool axes".
Yes, you can place the axis readouts anywhere you want them and they will work and only you know what your readout is telling you but it will work for you. This would probably not be considered good practice in a production environment, but in a home workshop you can do whatever suits you.
Cheers!

Hi Dick,
I am not quite sure what the Z axis is and I note that other people are also confused judging by some of your replies. However, I have added a digital readout to the long axis of my lathe that measures the position of the saddle along the bed.
For more information see:

Mike,
On a lathe the long axis which is parallel to the bed is known as the z axis. This can be confusing because when you stand in front of a vertical mill the right to left axis is the x axis. Despite what may seem logical, the axis of the revolving spindle is the z axis.
The z axis on a vertical mill is the spindle axis, the z axis of a horizontal mill is the axis of the spindle.

Hi Dick,
I am not quite sure what the Z axis is and I note that other people are also confused judging by some of your replies. However, I have added a digital readout to the long axis of my lathe that measures the position of the saddle along the bed.
For more information see:

I am strongly considering a Z axis digital linear scale for my 7 x 16 lathe.
I am thinking I might want to mount it onto the rear side of the bed below the saddle gibs. The scale would have a remote reader that I could place anywhere within 48".
Has anyone done this? I like to get as much info and learn of any experiences others may have had when doing this mod.
Thanks

Re: Which lube do you use
Every newbie should read that one at least before
buying a lathe.� "Tabletop Machining"� is another good one.�
Aimed at the Sherline ,but it's useful for 7x & Unimat users as
well.牋 Interestingly, books written about lathe work a hundred years
ago are germane to what is possible with a�7x machine; the big change was
HSS tooling and then carbide.

The
South Bend "HOW TO RUN A LATHE" book is very old, but the practices still hold
true today.
The
copyright has run out on it long ago, so it can be reproduced at no
charge.
I
have a PDF file of the book which I can email to you if you are interested. It
is a little over 3 megs.

Excuse me if this question has already been
asked but I am curious as to what you recommend to keep cutting tools cool.
Do you recommend a pump to flood the tool and material being machined, a
mist coolant spray, or the old fashioned chip brush dunked in cutting
oil? Most of my work爓ill be done with
aluminum.

Also is there
any one book that stands out from the rest as far as lathe and mill
practices that you might recommend to a newb?

Re: Which lube do you use
| I use rubbing alcohol on alum. 91% isopropyl. It works really good for parting and leaves a nice finish.. Just remember to wipe it off your machine and oil when done听 |

Re: Digital linear scale for 7x lathe?
It seems a number of people are confused by the X,
Y and Z axes. It is better to start without thinking of any machine. The X and Y
axes are at right angle to each other and cross the axis of the workholding
device. The Z axis is in line with, towards and away from the workholder. Thus,
the outline that Peter wrote is correct for a vertical milling machine. For a
lathe, the X axis is the cross slide and the Z axis is the carriage and any
movement of the tailstock quill. There is no Y axis on a lathe, unless you mount
a vertical slide on the carriage. It is easier to consider all movements in
relation to the workholding device.
