Re: DC power supply grounding
My whole life I have operated on the principal of a fuse is the first thing inline on the positive side after the source, switch, to the consumers. In some cases, DC, there may be a large fuse inline from source, switch or battery, that then branches off to other consumers. And those lines that go into separate consumers all have their own lower rated fuses. But never have I heard of fuses being in the return side or the negative side. Even though power, DC , runs from neg to plus side. Anyway, we are talking about the basic 120 circuit. I just looked up the circuit in my micro mark 7x16 lathe and sure enough, the fuse is located just after the switch on the power side.

Correct, it DOES matter that the fuse goes on the HOT side.
You essentially have one in, and two outs.? Fusing one of the outs is not doing you any favours.
In this case you can blow the fuse, and power is still going through your device - that can cause much excitement if the device isn't grounded, or even if it is (hot chassis and all that jazz).
And for the love of god don't put fuses on both the live & neutral.? (And yes, I've seen fused earths, gotta cover all the bases to be extra extra safe, y'know.? Gah. See)

The fuse can only protect when there is only one path for a return current and fusing N does not protect L from returning on GROUND. Yes, it does matter where the fuse is.
The purpose of a fuse is to protect the wires and prevent a fire.? In that case it does not matter where the fuse is. ?

There was a thread many years ago where someone was
planning on mounting their lathe vertically in their
van to take up less space.
No sure how successful they were.
Can't see why it wouldn't work, as pointed out
you'd need to counterweight the carriage (and
tailstock) to stop them squishing your pinkies when
they're loose.? Also means more chance of crap
winding up in the headstock.
Vertical lathes are a thing, although generally
reserved for turning really big stuff for wherever
reason.? They have their chucks at the bottom, which
makes sense if you you think about it.??
Aside from saving space, I can't think of any
real advantage of running a lathe vertically.? Might
as well push your mini mill over and use it
horizontally as well.

"You can also permanently mount the lathe on
end and use it vertically."
Have you tried this? I suppose it's possible,
but I don't see the point.? Something I've toyed
with (but haven't tried), is to hold a
mini-lathe vertically with the HEADSTOCK end on
top. This would be difficult because that's the
heavy end and there's nothing large enough on
the tailstock end to make a stable platform.??
But the point would be to convert the
mini-lathe into a precision miniature drill
press. You could make a lever action to operate
the tailstock ram and put the drill press table
in the tailstock, or you could put the drill
press table on the carriage.? I thought about
this for a long time, but I admit I became less
interested when I bought a mini-mill which also
functions nicely as a drill press.
Mike Taglieri?

I use cardboard. I use it under
the ways. Its deep enough to reach
from the front of the bench to
near the rear of the bench. I also
have large piece as backsplash. It
rests on the piece under the
lathe. Works rather well for me.
Collects debris, swarf and oil.
Lathe can easily be brushed clean
into the tray, then cleaned onto
the cardboard. It is then pulled
out and the swarf , etc, can
easily dumped. Then the cardboard
is then returned. Once it gets bad
it's easily replaced. The piece
under the lathe is cut to
perfectly fit.

(Unlike some larger

areas where oil could

Regarding
clean up, usually it
is common to just use
a brush(es) to brush
everything to a point
and sweep it into a
dust pan or
container.? Yes, most
chips fall down.? But
some will inevitably
go elsewhere,
especially on the
floor, onto the bottom
of your shoes, and
tracked elsewhere if
you aren't careful.?
(I just have an old
piece of regular
carpeting from where
my machine tools are
to a door into the
house and it works
nearly perfectly for
the "shoe" problem.)
I think
it is exceedingly
uncommon, if ever, to
use "dust collection"
with a lathe except in
an industrial setting
where a hazardous
material like pure
beryllium is being
machined.? Usually,
the chips aren't very
dust-like.? And if
using any cutting oil,
also damp.? Machining
cast iron will produce
something that is
closer to "dust", but
still not that fine.?
I would not relate it
to the dust produced
in woodworking.
For small
lathe, it can be handy
to have a little
removable tray that
just fits under the
full length of the
ways.? Most chips will
end up there and it is
easy to remove and
dump, and then, by
brush or vacuum, clean
the little that is
left around the area
and on the lathe.?
These lathes come with
a chip pan which the
lathe is bolted to,
but you don't need to
use it.? Sort of a
judgement call in my
view.? On a larger
lathe, you may be
using a lot of oil, or
coolant, and need
something to catch
it.? That's not
typical on a mini
lathe.
You can
certainly use a vacuum
device if you want.?
But you mentioned
"long swirls of swarf"
which I think are more
commonly called
"stringy chips."? That
suggests another topic
which is that you
should NEVER be
producing long stringy
chips.? They are a
hazard as they can
suddenly wrap around
and grab something
like fingers and
instantly pull them
into the spinning
chuck and workpiece.?
In fact, in some
machine shops,
producing stringy
chips can be a firing
offense.? They are way
to control chip
production, especially
having a "chip
breaker" feature
ground into the tool.
If you
want to store the
lathe front to back on
a workbench when not
in use, you might be
able to put the lathe
on wood or MDF piece
bolted near the end of
the bench (left or
right) where you want
to store it front to
back.? Then it could
just be swiveled to
normal position? ?Then
swiveled back to the

mixed-use:? wood
work (manual, plus

general

someday soon,
machining.
So,
in thinking about
getting a mini
lathe, I'm trying
to think about
how
it will fit into
my shop, in
various ways.? And
I'm sure other
folks
here have had the
same issues.
The
first is simply
space:? my shop is
"cozy".? I think
it's about 12'
x 12'
out of a longer
room that also
holds our furnace
and laundry
machines.?
I have two
workbenches, a
band saw, a
grinder/sander,
and a
drill
press in that
space, and some
low cabinets which
currently hold
my
CNC mill at chair
height.? The lathe
will live either
where the CNC
mill
is now (but
currently that
would mean sitting
and/or leaning to
use
it, rather than
standing), or on
one of the work
benches (but that
means
losing the other
uses of that bench
while doing lathe
projects).
It
might also be able
to live crosswise
at the end of one
of the
benches,
since the benches
are about as deep
as the lathe will
be
wide,
but I'm not sure
how practical that
will be.
Thoughts
on any of that??
Is sitting in
front of a lathe a
no-no?? It
works
for the CNC mill,
but they're
somewhat different
animals.
Second,
other than hand
tools and drill
press, the lathe
will be the
first
metal machining
equipment I've
introduced to the
shop.? Clearly
I'll
want a good cover
for the lathe when
it's not in use,
since it will
basically
be a magnet for
sawdust and dryer
lint, otherwise.
But
it will also be
generating a lot
of chips and
swarf.? How
controllable
is that?? Is a
"dust collection"
solution
possible?? I
assume
most of the chips
land under the
lathe, but how
much get
launched
several feet
away?? My shop vac
doubles as dust
collector
for
the bandsaw and
mill, and since I
wanted really good
dust
collection,
it's a Fein, and
has a bag.? But
its hose is just
1-3/8".
That's
okay for sawdust,
but I'm picturing
it jamming up with
long
swirls
of swarf if I use
it around the
lathe.? Will it be
at all
useful?
What
tricks/techniques
do you all use for
controlling
machining mess?
(I've
been watching a
bunch of YT
videos, and was
really hoping
Blondihacks
had covered this
-- it would be
right up her
alley.? But
haven't
found anything,
really, by her or
anyone else.)
And
finally -- a lathe
storage question.?
Floor space is at
a premium
in my
cellar, not just
in the shop, so if
I want to move the
lathe
elsewhere
(to free up its
workbench, or to
use the CNC mill
instead),
it
occurs to me that
storing the lathe
on end might make
finding space
easier.?
Can that be done?
I
know -- too long,
too many questions
in one post.?

Hello, Mark,
I forgot to mention that currently I am spending more and more of
my time with my little Unimat lathes. I found out I enjoy
machining on the smaller scale machines as well as the 7x16 scale
and possibly more so. It can more challenging and that might be
what draws me in that direction today. I have Two Unimat DB200
machines. Both about 50 to 60 years old.
They have vertical milling capabilities as well.
I am a longtime member of that group as well.
Have a good evening and enjoy.

I forgot to mention that currently I am spending more and more of my time with my little Unimat lathes. I found out I enjoy machining on the smaller scale machines as well as the 7x16 scale and possibly more so. It can more challenging and that might be what draws me in that direction today. I have Two Unimat DB200 machines. Both about 50 to 60 years old.
They have vertical milling capabilities as well.
I am a longtime member of that group as well.
Have a good evening and enjoy.
Dick

Re: MicroMark 7x16 Fault Notice
Hello Mark,
Good to hear from you.
I have the issue solved, finally.
A multi pin connector had become disconnected during my reassembly process. It was as simple as that, but took some investigation to zero in on the source. I am very happy I didn¡¯t have to go deeper. The continuity check verified the status of the fuse.

Re: Chris from Clickspring just dropped an new Antikyhera fragment video
??? ??? I can say for a fact that mr Clcickspring has forgotten
more about small machine work than myself could even imagine to
have learned . This guy just keeps amazing me with every tube he
puts out & we are truly lucky that he shares his knowledge
with us .

All of the Antikythera Fragment videos are very
worthwhile, imo, almost more than the main vids, because they¡¯re
about making the tools to make the thing.
He cheats, a bit, because he already possesses the
knowledge of turning so it¡¯s not entirely starting from scratch,
but then the Antikythera mechanism itself didn¡¯t spring fully
formed de novo from some ancient supergenius¡¯s mind. There had
to have been a long tradition of metalworking of complex devices
to get to that point.?

Re: Chris from Clickspring just dropped an new Antikyhera fragment video
Rather akin to the situation today where Frank Whittle is known as one of? the inventors of the aircraft?gas turbine. But who remembers that Edgar T. Westbuery did the precision machining that kept it together while it ran!? ?Bill i Boulder

Like this??

usually just tapping on the photo somewhere else makes it go away.
It only appears if you hold a finger briefly on that part of the image. I find that there¡¯s hard-to-gauge difference between getting it to work and getting it to NOT work, depending on the photo.?
It works the best if there¡¯s a clear distinction between the part you¡¯re isolating and the background, and the photo isn¡¯t too cluttered.
Once ¡¯tamed' the process is really useful for documentation purposes though.?
You may also want to play around with Settings > Accessibility > Touch > Touch Accomodations. some of the options there may help make it less sensitive if you keep doing it inadvertently.

¡°Photos¡± on newer iPhones & current iOS can use AI to automatically separate the images from the background, making it easy to copy just the image.

Re: MicroMark 7x16 Fault Notice
Hi Dick,
The fuseholders for these machines are't the best-made in the world.? The one on my old 7x12 broke off inside the chassis.? Nothing obvious from the outside and it took a bit of head-scratching to figure out what had happened.? Like you I had never found it necessary to replace the fuse.
Worth checking out.

You ask what would happen if QC was improved¡easy response... The cost would go up as would the quality(hopefully)..those costs would most likely be passed straight through to the consumer!
