Erie Tools SP2102, 7 × 14 variable-speed mini lathe review
The only real metal lathe in the American half of this hub — 7 by 14 inches, variable to 2,500 rpm, reversible for left-hand threads, with a digital readout and a cutter kit.
Where we come out The only real lathe in the American half of this hub, with the second half of the spend partly included — and with its spindle bore unpublished.
Eight of the nine American machines on this shelf are mills. This is the lathe, and it belongs to a well-known class: the 7 by 14 mini lathe, which means a 7 in swing over the bed and 14 in between centers. Those are the two figures this hub compares lathes on, and both are in the title.
What makes the listing worth attention is what comes with it. This hub’s buying tip is blunt — the machine is about half the spend, and tooling makes up the rest — and this one arrives with a five-piece carbide-tipped cutter kit, internal and external chuck jaws, eleven feed-rate change gears, a chuck key, a manual and a digital readout. The change gears matter: eleven of them is a usable range of thread pitches without buying a gear set, and a DRO bought separately is a substantial sum.
The variable speed runs to 2,500 rpm in both directions, and the reverse is named for the right reason: left-hand threads, which a single-direction lathe cannot cut. What the page leaves out is the spindle bore — the third figure in this hub’s own introduction, and the one that decides whether a length of bar can be fed through the headstock. There is no runout figure, no motor rating, no weight and no minimum speed either, and three of the four bullets restate the title.

What it handles, and what it will not
Strengths
Publishes the two figures this hub compares lathes on: a 7 in swing and 14 in between centers
Variable speed to 2,500 rpm in both directions, which is what makes left-hand threads possible
A digital readout included rather than sold separately
Comes with a five-piece carbide-tipped cutter kit, internal and external chuck jaws and eleven feed-rate gears
Eleven change gears means a range of thread pitches without buying a gear set
A chuck key and an owner’s manual, which sounds trivial until one is missing
Compromises
No spindle bore published, which this hub’s introduction names as a key lathe figure
No runout, no motor power and no weight published
A 7 by 14 mini lathe is a well-known class with well-known limits in rigidity
The lowest speed is not published, only the 2,500 rpm maximum
Three of its four bullets are a restatement of the title

The questions welders ask
Why does reversible rotation matter?
Left-hand threads, and finishing. A lathe that only turns one way can cut a right-hand thread by feeding the tool towards the chuck; a left-hand thread needs the feed reversed, which on a screw-cutting lathe means reversing the spindle. The listing names that use directly. The second benefit is a tool mounted upside down at the back of the work, which with reverse rotation gives a cleaner finish on some materials.
What does the included tooling save?
Most of the real cost. This hub’s buying tip is that the machine is roughly half the spend, and that chucks, tool posts, collets, a vice and measuring gear routinely equal the price of the lathe itself. A five-piece carbide cutter kit, two sets of chuck jaws, eleven change gears and a digital readout in the box is a meaningful part of that second half — and the digital readout alone is a substantial separate purchase.
What is missing from the specification?
The spindle bore, which this hub’s introduction names alongside swing and centers. Bore decides the largest diameter of bar that can be fed through the headstock and worked on at the chuck, which is the difference between turning a shaft and turning the end of one. On a 7 by 14 lathe it is typically around 20 mm (0.79 in), and this listing does not say. Nor does it publish a runout figure, a motor rating, a weight or a minimum speed.
