There must be a standard way to do this - say
center marked aft end of piece
against the tailpost needle - frustrating, adjusting
independent jaws.


I've this plastic cone on a rod
and 1 3/4" diam cone shoved into chuck like fat
tailstock needle, centers jaws.

I don't know what this hard plastic cone thing is, came from an
auction's box of tools. Stout, and perfect Taigable size.

Center drills size #2 and smaller.
For taps, I use 1/4"-20, #10-32, #8, #6  most often. Depends what you're
doing though.
I prefer "gun" taps for most tapping if the hole is deep enough as they are
sharp and shoot the chips ahead rather than packing them in the flutes. I'm
also using "form" taps more and more (they don't cut, but forge the thread).
Don't skimp on taps.
For dies, get split adjustable types.

I'm not using that brand in perticular, but am using a water based
coolant. They wont cause any rust, dont have to worry about that. As
the water evaporates it leaves a film of oil over everything to
protect it.

They can cause problems with CNC mills. I got some into an encoder
and shorted it out. In the future i'm thinking about making some
sort of guard that will cover the X and Y servos. Just be carefull
and good luck.

Just thought id mention something else to anybody using a flood
coolant setup.

There was some talk here before about keeping the chips out. My
soloution was to just not let the pump go to the bottom of the
bucket and it worked OK. But occasionally i would get a peice of
metal jammed in the nozzle and it got to be a pain cleaning it out.

I wanted to make some sort of filter but couldnt decide what to use.
I didnt want to use a cloth filter because they drain too slow and
most of the screens i knew off were too coarse and would let too
much metal go through. Finally found the anwser in the kitchen.
Those things that go over frying pans. I cut the screen out of it,
and made a bowl shape and it works great. Just have it hanging at
the top of my bucket and the coolant drains through it on its way
down.

Anyway, thought id mention it in case anybody is in the same
situation with chips jamming in the nozzle.

I also use #4-40 and #2-56 a lot.  #0-80 when I can't think my way out of
that hole (happens...)  Nick's right.  This depends a lot on what you're
doing.

One of the guys at work got me into using spiral flute taps for blind
holes.  They work great.  A beastie I made for work involved tapping 64
blind M3 holes.  It wore out my drill to drill them, but the tap is still
sharp and cutting nice.

How do you like those forming taps?  How small can you go?  I've seen
them, but every time I think of the forces involved on something the size
of a #2, I just cringe.

> For dies, get split adjustable types.

Amen ma brudda!

If you have the cash to spare, a set of piloted counterbores is also nice.
(Now if I could just find where my #4 got off to!)

Hi Folks,

As Nick stated, this is a recent version of the virii spreading around
the net.  I just got off the phone with Adelphia support, having
received a similar message indicating that email was going to be down
for two days and to install the attached "email forwarding" utility.
Weird headers, origination outside of the adelphia network (even though
allegedly from Adelphia), odd spacing in the text, and a forged reply
were all the signs of a scam.  A quick check with Adelphia support
confirmed that it was not a valid message from one of their vendors.

Odds are that Nick has a perfectly clean machine, and that his email
address is simply being used as a forged "reply to".  As I'm active on
quite a few groups you may see a few that appear initially to have come
from me.  I don't send unrequested attachments, and typically email
ahead to the person letting them know to expect one from me.

So even if you trust someone, don't open attachments that you don't
expect.  The email addy may be one you trust, but the email may not be
in fact from that person!

Cheers,
Stan

Indeed - this is a new variety. Aside from spelling errors they look
very plausible. It's real fun when you get 3 different
authentic-looking varieties in just 1/2 day, one claiming to come from
myself to myself... :)

1. Don't use outlook. (that will save you from some tricky virii that
'auto-open' without you clicking on them).
2. Don't open any attachments that end in .scr .pif .exe .com.

These two rules help save your butt from probably 99% of the most
common viruses.

Read mail on UNIX machines.  99.9999% of the harmful stuff people send in
mail just plain won't work under UNIX.  (Besides, filtering's dead easy to
set up so it strips those .SCR .PIF .EXE and .COM attachments from your
mail.)

But I digress...

I am astonished at your site of Taig enhancements.
Your DIY Taig Headstock Dividing Head is the most
exquisite Taig mod project I've ever encountered.


Have you John Harrison Albion's blood of "H1" laudable
longitude fame
in you?!

Your leadscrew carriage feed is second.

The question is, are there other Taig DIY projects
out here that you marvel at?

I searched messages of this yahoo group -
and could not find
posts to your site.

I wonder if the folks here know what you've done.

It's not only accomplishing such superb Taig DIY
original creations, but you've
documented in detail for the rest of us.

If you haven't seen this- people - please do marvel at:

Your talented work is the best Taig endorsement I know of.

So Tony, any other's Taig projects you admire?

And -

thank you.

I like them a lot. If you think of it, they are stronger than a cutting tap,
especially in the smaller sizes as they have more meat on them They also
tend to require less force if you got the tap hole size right and use lube.
They are really only for ductile materials, but I use a 1/4"-20 one on CRS
and it works just fine. I like the lack of chips.
My good machinist buddy uses them for #2 and even smaller all the time,
power tapping with one of those Wilton tapping arms in aluminum.

Zoiks, Scooby!  Power tapping with a #2?!  Dude, I'm in!

Most of what I do is in aluminum or brass anyway.  That seriously sounds
nice.  Think half hard brass is ductile enough to make a forming tap
happy?

I bit the bullet years ago and picked up a set of fractional reamers and a
set of over/under reamers.  I don't use them often (though I do OIL them
often).  But when you need a reamer it's a heckuvalot handier than having
to make one or wait to buy one.

Take arbitrary quality spirit from a level - e.g.,

Attach a compatibly small magnet - these powerful

parallelism doesn't matter.


Attach perpendicular spirit-glued-magnet to say, e.g.,
plumbed mill column - or ferrous plate affixed to alu.

turn spirit till bubble is true.

If column becomes unplumbed - and the magnet is secure,

Regarding worn lead screw nuts.  There is a product called "Moglice" which
is used to repair machine tools.  According to the company it wears better
then bronze in most applications.  It is used to repair ways, dovetails and
other precision brearing surfaces.  It is a two part plastic and would be
cast around the lead screw forming a new nut.  I have no connection with the
company other than as a user of their product.  Their site

I'm hanging "paper bags" off the headstock T-slots, and
from what I see, so is everyone else.

Taig's wonderful insite and advantage that I value
is the generous and thoughtful distribution
of T-slots on-well-`bout everying.

So why not down the entire sides of the headstock? Like - you
could separate the halves and you've got two milling
tables.

And add say, 3/8" depth below its dovetails, more
meat and potatoes to be drilled and
tapped - so we can part these jewels off onto new orthogonal
tangles.

This adding below would not be backwards
compatible to extent riser blocks however-so these
need a cut too.


The tightening screws undo the headstock's
sides and top squareness, but that could be shimmed
if desired.

Paper bags? I know you like to write in a fashion that mimicks your
thinking process, but it's disjoint and confusing to say the least.

Your insights are original and refreshing when I do "get it". But you
have me stumped on paper bags?

My aplogies Jay for being too arcane,
"paper bags" first
referred to "software bloat" when
programmers became disgruntled with
adding tedious add-ons to core projects,
rather than re-thinking the project
itself.

This was said to be fixing paper bags
to the side of the monitor or the box.

I use my Taig for truing T-jet armatures, thanks to guidance and input
from this group. Here's the technique I've evolved:

I hold the arm in the 1/4" Taig collet. I made a reducer bushing from
1/4" 6061 aluminum rod with a reamed 1/16" hole. I split the bushing
with a jeweler's saw so that it compresses on the arm shaft when the
collet is tightened. To support the arm on the tailstock end, I made an
aluminum bushing that fits on the end of the arm and engages the Taig
live tailstock.

I spin the arm at the second fastest speed, and take very light (.0005")
cuts per pass with cheapo Harbor Freight right-hand bits with carbide
inserts.

Problems: If you catch one of the arm laminations on the interrupted cut
and the arm spins in the reducer bushing, you lose the clamping force
because it wallows out the soft aluminum (highly technical term). My
next step is to make the reducer out of brass, and slit it crossways
(four "fingers") so that it can hold the arm shaft more securely.
Actually, having the arm spin in the bushing is a safety valve, because
it prevents you from spinning the commutator on the shaft and totally
trashing the armature.

The other problem is that the live tailstock doesn't turn at the spindle
speed; even with only a light preload, there is too much drag. To
prevent galling the aluminum support bushing on that end, I put a dab of
synthetic grease on the arm shaft. That's cured that problem.

After doing a dozen or so arms, I've decided that grinding the OD is
probably a better solution than machining it. I've built a fixture to
hold a Foredom flex shaft grinder handpiece on the cross slide (there
are several examples on Nick Carter's website) -- sort of an imitation
tool post grinder. On Tom Benedict's advice, I bought the reversible
Foredom so that I can countergrind the arm; most grinders (Dremel,
non-reversible Foredom, Harbor Freight, etc.) rotate "with" the spindle.
I'm going to sacrifice a few arms this weekend to see whether or not
this setup works.

Good luck!

Hope this helps,
Rick Voegelin (still playing with toy cars)

Hi all, I recently bought a Taige / Peatol lathe, and have been
looking round a few of the groups for pointers on how various
operations are carried out on the lathe.This brings me to the reason
for my first post to the group, I need to bore some holes accurately
in some pieces of aluminium 1-1/4" square x 5" x 1/8" thick.Using a
boring bar in the toolpost isn't feasable as the holes, which are to
seat bearings  are at the ends of the pieces. I have a copy of "The
amateur's lathe" by L H Sparey, which shows a boring bar which
passes
through the workpiece. Has anyone used this system? and if so, can
anyone tell me how the tools are best made - or where to obtain them
(please).Also in the same book, flycutters are under the heading of
boring tools, would a small diameter flycutter cut a reasonably
accurate hole in this material? (the bearings are to be inserted
after the aluminium has been heated to expand it - the bearings will
have been in the freezer overnight)Any advice or information would
be greatfully recieved.
