Re: Making springs

 

Making your own springs is the best option if you need a one-off
spring, or something out of the ordinary. Another option is to buy a
length of spring stock and just cut out a section to suit your need.
Companies like Reid Supply Company sell lengths of spring stock in
varying sizes and materials (piano wire, stainless, etc.). And it's
cheap, usually just a few dollars per length.

Re: Best Plastic to use

 

Turning epoxy resin and/or using it as a handle can cause a problem
for some people because they have, or develop, contact sensitivity to
the resin. This may result in an allergic reaction, anything from red
skin and/or itching to swelling to difficulty breathing. The allergic
reaction is generally not immediate, it can take 12 hours or more for
symptoms to develop so it is easy to miss the connection between
exposure and symptoms. The allergy is mainly to un-reacted hardner so
chances of a reaction diminish over time and also if the epoxy cure is
accelerated by raising the temperature.

Be alert for any of the above, especially if you turn this material on
your lathe since the resulting additional surface area brings
additional risk of a reaction.

Hi,

For making plastic handles on shafts I turn a few grooves (for

cast the handle with fibre glassing resin from the hardware store.

Use oversized PVC conduit as the former so centre isn't critical.
Glue a piece to some scrap with silicone, etc. Then spray the
inside
lightly with WD40 as a release agent. Support the shaft by clamping
from above and pour the resin in. Next day, stick the shaft in the
chuck and turn off the PVC. If the WD40 has worked well you won't
need to machine much before it slips off anyway. Discard that and
continue turning the resin to shape. Fine cuts go smoothly and
produce mountains of fine stringy swarf. Don't let them build up or
the job will eventually grab the whole pile and wrap it up! Finish
with emery or wet & dry if you want a nice polish.

Re: Tap and die sets

 

Hi Andy.
I was actually thinking likewise and having read your comments now
know I was right!
I am using 12mm aluminium rod and having turned it down an inch from
the end attempted to cut a 8mm thread, which did not work out too
well. Then I thought why not drill and tap a hole and use a screw
instead or just screw in a piece of 8mm thread and still use a nut on
the end. Still waiting for delivery of a tailstock chuck so have not
been able to try it out.

Paul, I hate cutting threads on or in aluminium, because the swarf
seems to stick to the tap or die and to tear out the threads as you
progress. One method I have used with (limited) success is to sort of
"form" the thread rather than cut it. For an external thread, I have
used rod a bit under half way between the outside and core diameters
of the desired thread, taper-turned the inside of a plain steel nut of
the desired size, and then (with lubrication) forcibly screwed the nut
on to the rod - basically, squeezing the aluminium into shape.
Similarly for internal threads, using a bit over half-way sized hole
and a tapered bolt.The results weren't terribly pretty, but good
enough for my needs. The internal threads were better, because it was
easier to emery off the machining roughness left on my "tap" than it
was to smooth the inside of my "die".

Re: Best Plastic to use

 

Hi Rance,

You've basicly got it except the first 2 parras go together to
describe how I put a handle on a hand tool shaft. For example, I
recently cut down a screw driver since I needed a little carbon
steel and also needed a very short screwdriver. By keying I meant I
didn't want the shaft to move in the new handle. A couple of grooves
turned in the steel shaft stop it pulling clear out of the resin
(axial direction) and a couple of flats ground on the shaft stop it
twisting in the resin (rotational direction). Is that clearer?

The last parra was a standalone comment about how the guys in the
workshop of my previous employer used to cast blocks of the stuff.

I follow what you mean about the cardboard. However, I think you'll
change your mind after trying it. The resin is pretty runny before
it starts to cure and the cardboard will probably end in a sticky
disaster. In any event the resin will likely soak in so far that you
will have little chance of soaking it off. Having worked with the
stuff in a previous life I went the PVC, silicone and WD40 way to
avoid getting messy.

I've previously used aerosol caps, etc. as formers. Anything that
comes to hand that's disposo and won't leak. Apart from the copious
swarf it's nice to machine. It also does a pretty good job at
bonding to itself if you need to cast in layers. Sometimes that
becomes necessary if doing large volumes and you don't want to risk
the curing heat melting your Chinese takeaway container mold!

Re: 1st Timer Accessories-Which 4-Jaw chuck?

 

Thanks for the comments from all. I understand about the jaws

though. I thought about the 6" but I just don't know. I'll wait on my

G'day rance.
All you have been told so far is sound, if perhaps confusing.
IMHO; chuck selection will depend on what stock you get. Round and
hex
stock only needs a 3 jaw self centering chuck, it will be the most
convenient and have semi permanent residence on the lathe. You can
even
off set pieces for eccentric turning by means of packers.
But soon you will need to face or bore an odd shaped piece, then
its 4
jaw chuck time or even use a face plate. Ive had my lathe 10 months
and
haven't used the face plate yet but they are cheap and just worth
having. You can get by with only a 4 jaw chuck but each job has to
be
set up rather than just thrown in the 3 jaw SC chuck. You will need
a
dial indicator and magnetic stand. If you are really clever you can
use
the cross slide and shims (cigarette papers) to get the work
centred.
Get the biggest chuck/s you can afford and swing in the lathe,
remember
the jaws sometimes extend beyond the perimeter of the chuck.

You will need chuck and arbor for the tail stock, even if only to
drill
centre holes; this also means centre drill bits.

You will be a centre for the tail stock as a minimum. A live centre
is
not essential, you just need high pressure molibdenum grease.

I'll make some comments about tooling in a following post.

Folks, Sorry for the late reply but I've been out of pocket (ie.
working a side job to pay for the HF 8x12 that is on order.). I'll fill
you in when I get it in my grubby little hands.

Thanks a bunch for all the replies, comments suggestions and
encouragement. I particularly like Ian's suggested use of the angle
grinder for roughing. That's a $10 tool from HF. And I could mount it
to the bench too. I also have a newer appreciation for the tangential

carbide inserts for threading (initially) but grind HSS for all my
other applications. Thanks again for all the comments.

Re: 7x12 capability

 

Me agen John.
I have looked through Minitech's offering, they don't seem to have
spare threading dials either; but you should ask.
I must admit that during the drooling over catalogue stage the
threading dial was one of the things I looked for. I had only ever
cut inch threads on imperial machines so was not aware of the
complexity of chasing metric threads. That reminds me the threading
dial is also called a "thread chasing dial"

The pinion is quite simple and you could probably cut you own in
aluminium. Turn up a blank then the use the change gears as an
indexer. By grinding a tool with the Acme thread profile you could
mount it on edge on the lathe centre line and then traverse it along
the blank with the saddle using the cross slide to set the cut depth.

There must be a better way with metric threads but i haven't worked
it out yet. I recall there is a third method after reversing the
lathe, using the dial and.......?

As an aside, the 7x12 had the features that our Workshop Practice I
instructor told us to look for when assessing a lathe, e.g, a prism
bed, tumbler reverse, back gear, thread cutting change wheels and a
thread chasing dial.

Re: 7x12 capability

andrew franks
 

Chris, I had a 3.25" length of 1" diam. aluminium handy, so I've just tried facing it in my 3-jaw, without using undue force to tighten the chuck. In fact, the chucked end was a smaller diam. for a quarter of an inch, so the effective grip was on less than 0.5" of the job. Using modest (3 thou or so) increments, it faced up nicely - can't see any appreciable light getting through when holding it up to the window, against a straightedge.Would be a long job, though, if there was much metal to be removed to achieve the right length, and a travelling steady, as Ian recommends, would enable more ambitious cuts.

The job is well within the capacity of the 7x12 lathe. My concern

the overhang from the chuck. There is a risk that the work could

it is softer to hold. If the work was any longer I would definitely
use
a fixed steady to give support at the work face. Use a steady to be

the task and HOW to perform the threading task ( what gear set up ect ).
Harbor freight has 2 7x10 lathes listed that look identical,
there is a $10 price diferance...... which is better? what is the

Hope this helps; must get back to work.
One good turn deserves another.

G'day Moszziesplat.
The job is well within the capacity of the 7x12 lathe. My
concern
is
the overhang from the chuck. There is a risk that the work
could
skew
in the chuck due to the cutting forces. Being aluminium
doesn't
help,
it is softer to hold. If the work was any longer I would
definitely
use
a fixed steady to give support at the work face. Use a steady
to
be
sure. Consider getting steadies with the lathe, often they
come
as
a
cost effective package.
BTW, with an handle like Mozziesplat and spelling Aluminium
correctly
you must be Australian.

off.

question.
Could anyone please advise.
Cheers Ian the work skewing due to the tool forces at the end of
the
work were exactly my concerns. What is the maximum diameter of
stock
that will fit through the fixed steadies ... You chaps down in
Australia still spell aluminium correctly like us in the uk, the

Re: 7x12 capability

 

G'day Chris.
A quick trip out to the workshop showed that the steady fingers open
out to fit 45mm diameter. I haven't tried anything this size but 25mm
should be a breeze.

You would have to go up a few lathe sizes to get one that will allow
25mm through the headstock spindle.

The lathe has the power, I face 50m x 25mm Ali blocks without any
problem.
Hope this helps; must get back to work.

Doh ..... Do I look as stupid as I feel? I figured it out late last night.

Bill, I know this sounds a bit obvious, but are you sure that, if
there's a hinged chuck guard fitted, it's lowered? If not, lower it, press
the green button to reset the safety switch, and try again!

Hello All,

I just drove two 3 different HF stores and bought the 7x10 mini lathe.
I take her home all proud and I pull it out of the box and she looks
GREAT! I then start wiping the red pain in the #%@ grease off of it.
Takes an hour or so to get it all off and rub her out. I plug her in
and start up the motor first in low for a few seconds and I turn the
speed knob to see the speed. I then put it in high gear and turn her
on and turn it up to see the speed there for a few seconds. Then I
went to try her in low gear and .... NOTHING!

The fuse is good the lighted switch is lit up, what could it be? I
have removed the cover to look inside at the wires, all looks good. I
cant smell anything so I know nothing smoked. I have the4 speed
adjustment knob off before I start like the manual say to do. still
... NOTHING!

Any Clues?

Bill
