Re: minilathe for children.
I have to say, without VERY careful adult supervision, I'd expect blood-red marks on fingers, at least at the start. Eight seems awfully young to turn a child loose on power tools.

Re: minilathe for children.
This is a typical piece of aliexpress junk, and not a lathe at all. I would not give it to a monkey leave alone one of my children.

Re: is this an original minilathe
Jeez, so much said with no consensus to be ever agreed on. Maybe instead of saying mini lathe and such, just state the actual size you are talking about. Simple. Otherwise there will be more talked about the term rather than the actual issue of a particular lathe. So any discussion should state the actual size and not mini lathe as an example.

I would say absolutely not. There have been a VAST number of small lathes produced, often for watchmaking or model making purposes.
However, this does bring up the question of just what IS a "mini lathe." I doubt there is some specific definition to distinguish it from just being a small lathe. But I think there might be some criteria. And also, what seems have developed in the lexicon of lathe types commercially and casuall
Good question.? I know first time I heard the trem for a? mini lathe was a low cost lathe and using the lead screw for power feed and no power cross feed. Under 7" swing. But there was a gap from 6" to 9" swing.? A 9" lathe was a smallest lathe. I would use term MINI LATHE? for lathes between 7" and 8"

[9x20lathe] My lathe mods. indexer unit
got this from the 9x20 group , may? be some interest to some
animal
A simple indexer for the 9x20
lathe
?
They have been
many times when I have wanted to index something in the lathe so
in an effort to improve the slapdash way I usually do it I came
up with the following.
First an
expanding mandrel to hold a change gear in the back of the
spindle.
The cuts for the
expanding segments were done with the angle grinder which is why
they are skewed.
The keyway was
cut by holding the mandrel end somewhat insecurely in a tool
holder but it worked.
This same
expanding mandrel also hold the manual handle when I want to go
really slow like when threading up to a shoulder.
Next we need a
pin to sit in the teeth of the gear so the spindle cannot turn.
I dismantled the
sprung lever for the gear box to see how it was made and
basically copied that.
Obviously the
end of the pin must be cut to fit in between the gear teeth so
once again I held something in the tool bit holder and used a
cutter to mill away the two sides.
This time though
all 4 screws held the part.
Then made the
cap that pulls up the pin against the spring, just like the gear
lever.
To hold the pin
assembly I made a steel bracket from some 10x25mm flat bar.
The right angled
section can be adjusted in height according to the size of the
gear used.
Then drilled and
tapped 2xM8 holes to bolt it down to the head stock once is was
aligned to sit vertically over the change gear.
Some times I use
a printed degree wheel in place of the change gear but then its
difficult to lock the spindle in the required position.

Re: is this an original minilathe
I have to disagree on that.
Terms mean what their actual usage defines.? (Numerous words in the dictionary have had their definitions changed for precisely this reason.)??That actual usage becomes the lexicon that, in my opinion, people should use instead of making up their own.?
I guess I can only speak for myself.? But after doing machining for about 60 years and having owned a "mini lathe" for 15 or 20 years and been on the mini lathe group (this and the former one) for the same period, seeing countless advertisements, YouTubes, and you name it, the term "mini lathe" is overwhelmingly a specific reference to the 7XSomething Chinese small engine lathes.? Not the next smaller size.? Not the next larger size.? Yes, sometimes you see somebody extending the term to something else, but not often.? If it is extended to something like a German made lathe equivalent in size and features (7 inch swing engine lathe) perhaps that's arguably under the umbrella of that term.? But regarding a watchmakers lathe, Unimat, Sherline, Taig, jeweler's lathe, or the like it would not apply.
Incidentally, "mini lathe" is also used in the woodworking community for small wood lathes that are maybe 8 to 10 inch swings.? That is NOT inconsistent with my position, since the term in either the metal working or woodworking commercial space would be context sensitive.? On this site, we are talking metal working.

I have not previously heard of the 6" version -? when were these made?

LMS 5100 7x16 Mini-Lathe Aligned
?
?
Having previously fiddled with headstock alignment on the subject lathe in the past without success, I have now done the full process.?? The lathe alignment before work was:
?????????? Vertical???????? 0.005” high in 9 inches toward the tailstock
?????????? Horizontal??? 0.009” forward in 9 inches (in line with known 0.005” in five inches from previous measurements)
?
In a recent topic, some shortcomings of this lathe were mentioned.?? And lathe upgrades had also been mentioned.??? One being tapered roller bearings in the headstock, and another being a fourth headstock hold down bolt.
?
The 7x mini-lathe certainly lacks rigidity which can easily be uncovered and displayed, and was the primary reason for upgrading to four headstock hold down bolts.?? Lock washers were used on all the bolts.
?
Because of the factory poorly fitted headstock, the lathe alignment process uncovered the fact that adjustment could be changed with tightening of the four bolts an additional amount.?? Likewise for a bit of loosening. ??I had no intension of any loosening. ??So some 15 iterations (probably more) of shimming were involved.?? Not all efforts delivered the expected results.?? A lot of measuring and rechecking measurements were done.
?
In the end, after considerable frustration with unexpected outcomes, the final results are:
?????????? Vertical???????? 0.00015” in 9 inch toward the tailstock
?????????? Horizontal ?? 0.0002” forward in 9 inches? (retaining concavity)
?
Pretty good – probably more flex in the machine than that.

Re: is this an original minilathe
Craftsman sold 2 different lathes that would fall into the class
as these 7" lathes . I have had a couple , ( though missing a
tailstock for one ) for several years now & so far they only
occupy shelf space , Though they appear to be quit nice lathes
talkin to other folks that have one they are a lesson in
frustration . One guy told me that if a guy can good parts on one
of these 109 series lathes they he could make fantastic parts on a
real lathe . These lathe were made in the late 30's & up .
