Re: Tailstock #2MT reamer revisited #2mt

I agree.More than likely just simple hand pressure with a reamer will
clean up the MT bore.

Hi Chris,

Now is the time to get old fashioned. Use the reamer with a hand
wrench, like a tee handle tap wrench to clean out any burrs or high
spots. Use a known good #2MT something and some markym dye to find how
you are progressing. It is too easy to cut too much with a machine
feed, do it by hand and take your time.

You can align the headstock to the tail stock when you are done. Chuck
up a piece of round stock and machine a point on the end and leave it
in the chuck. Then align the tailstock to it with a center in the
tailstock. I am assuming that the lathe has been checked for level
before this alignment procedure is done.

perfect fit, and need to clean up the tailstock via a reamer.

Chris

Mount your dial indicator on a faceplate or chuck. If you have a
good MT arbor mount it in the tailstock and take readings on it as
you rotate the headstock chuck by hand. Adjust the tailstock with
shims and the adjusting screws to get a consistent reading at the top
and both sides of the arbor. This will get the arbor end of the
quill lined up but won't garantee that the quill itself is
horizontal. Fully extend the quill and with the test dial mounted on
the xslide check the top of thw quill along its length and shim as
necessary. You might have to repeat the operation a few times to get
everything lined up.

You should be able to hand feed the reamer. Unless the socket is in
really poor shape the reamer will line its self up. You should be
only taking a skim cut anyway.


Good luck.

Thanks for the info,

Count me in as interested. I would like to see faceplate blanks,
steadyrest, cathead, traveling steady, toolpost mods, tailstock
specialties ( die holder, live tail, thru-hole types, etc.)etc. maybe
we could get a local ( groupwise that is) to do the basic machining
of the bases and clamps for a batch so that those without a mill or
shaper could enjoy the wealth also. I can do some clamps but probably
not the bases.



If you are thinking there will be a good price break for a volume
order I would like to get on the list for one. If, like you say,
they
charge by the pound then it won't make any difference. I would
still
like to know what they will run.

The rotating center (slang is live-center) is absolutly fixed on
axis. As far as the work goes, it would not see any difference
between a solid and rotation center.

The ball bearings are not there to allow for any mis-alignment.

You really need to get the tailstock aligned properly.

As for the hand reamer, it should work.

A #2, MT finishing reamer would cost about $30.00 from a supplier. I
had bought one a few years ago and offered to pass it around the
7x10minilathe group, but it got lost and never made it home.

I too would like to use one to clean up a tailstock.

Depending on the part, I might make a holder-wrench for the tailstock
sleeve, chuck the reamer in the 3-jaw and slide the sleeve over the
reamer. Then use the carriage to put some feed pressure on it and
rotate the spindle by hand.

Re: Tailstock #2MT reamer revisited #2mt

Thomas G Brandl
 

Chris,
I think first you need to determine where the movement in the live
center/tail stock is. If its between the live center and the quill, then
yes you will need to ream it. Also, check between the quill and the
tailstock housing. I wouldn't use a chuck to align the reamer. Or if you
do, turn the taper/angle on a piece of steel rod and don't remove it from
the chuck. If you have collets, then that will hold a piece of round stock
to be turned also. Or hold a center with a straight body. Then you can
check the alignment by eye. I would roughly align by eye, then use a test
bar and a dial indicator. Both from the side and from the top. You can also
use about a 12 inch piece of round stock and turn it between centers to see
the taper. Then adjust the tailstock to take out the taper. Only after you
have aligned the tailstock to the lathe would I ream it.
Tom

Wood patterns ?

Ideas :

a fixed, clamp on carriage as the basis of a CNC clamp on fixture.

A channel for a CNC axis, probably 6" wide, by 10 inches long, by 1/2

large dia steady rest for my 9"

South Bend Small Bore Heavy 10"

Raymond Frenkel <rfrenkel@...>
 

Hi Ron,

I have a heavy 10 with a 1 7/8 – 8 spindle thread and a 1 inch through bore with a #3 MT. The table in the SB FAQ lists the specks for this type of spindle.

My lathe is a 3-½ bed with a slide gear and a one lever QC box. Catalog # 8199ZF and bed # 356RKR7.

Is this the info you are looking for?

While all the software listed is good, my personal preference is for TurboCNC as the controller software.
Version 4 which was recently put out is only $60 to register and it was originally designed to run a lathe!

You can download the full version of the software (no cripples) at www.dakeng.com and then if you join the TurboCNC group on yahoo, in the files section are the latest updates. registration gets you the source code so you can make your own modifications if you desire.

I use it in combination with SheetCam as my cam program and am extremely pleased.

I think they reference Large bore and Standard. A letter "L" in the

the term small bore is used for this model. JP

George, Tim,

I have done a bunch of work with balancing machines at General

The spindle hangs in a cradle and the cradle can move along one
axis
only.

Picture 4 flexible rods hanging from an overhead support with
bearings
on each pair, spindle and part to be balanced in the bearings.
Put a
belt around the spindle and run it to a motor bolted on the
floor. The
belt rotates the spindle and also keeps the spindle from moving
up and
down but allows it to rock from side to side. Place a motion
sensor on
the side and synchronize the peak output to a rotary marker or
flash a
strobe and you have an out of balance indicator. It gives you the
location and intensity. Crude example but it gives you the idea.

On the unit you see in the garage the spindle is mounted on a
compliant mount which acts similar to the above example. The
spindle
must be allowed to move a little bit to work, sometimes it is
mounted
on the end of a leaf spring or whatever idea the designer dreams
up.
