Grizzly G4000 9 x 19 vs VEVOR 7 x 14 benchtop metal lathe

• You want the larger envelope. The G4000 lists 8-3/4 in of swing and 19 in between centers, against the 7 x 14 class of the VEVOR. That is the difference between small pins and a part you can hold.
• You want every dimension before you commit. The G4000 lists footprint, weight and amps, and our layout engine gives a result for six bays.
• You buy direct and want a parts line. Grizzly sells the lathe, parts and freight from one place.
• The lathe will be a fixture. At 294 lb it sits on a strong bench and stays there. Mass helps a lathe cut, since light machines chatter.

• You want to start small and cheap. The VEVOR sits in the under $1,000 tier on Amazon, with the Amazon return path.
• You want variable speed and a display. The title lists a 550W variable-speed motor to 2250 RPM and an upgraded digital display.
• You want a lighter machine to move. The title says benchtop and mini. Check the listing for the weight; our sources do not give one.
• You want a tool box in the box. The title mentions a precision tool box. Check the listing to see what is in it.

Lathe sizes are swing by length. The VEVOR title says 7 x 14, a lathe that swings about 7 in over a 14 in bed. The Grizzly G4000 is 9 x 19, with 8-3/4 in of swing over the bed and 19 in between centers. That is a gap of roughly 1-3/4 in of swing and 5 in of length. In metalworking terms it is the gap between turning small fittings and turning small shafts.

We researched both from manufacturer listings, published specifications and owner reviews, and we did not test either one. The VEVOR figures in this page come from its title only, so voltage, amps, weight and footprint are for you to read on the listing. Before you buy, write down the longest and widest part you expect to make. If it fits inside 14 in and 7 in with room to spare, the small lathe is enough. If it is close, buy the larger one. A tool that cannot hold the work is no savings. The lathe and mill roundup sets out the tiers.

Our layout engine placed the G4000 alone in each of six standard bays, then beside a parked sedan with walk-around clearance, then stored.

It takes 2 percent of a 12 x 20 or 12 x 22 ft floor and 1 percent of larger ones. The 16 x 37 in footprint is modest, and a lathe does not have a stock lane the way a table saw does, so a back wall and a bench are all it needs. The 30 in operator halo is the bigger part of the space it uses. A smaller lathe saves little floor, since you stand in the same spot. What it saves is the weight and the bench. The G4000 fit sheet shows all six bays.

This is where the two machines part ways in a garage, and our sources only give one side. The G4000 ships at 294 lb. The VEVOR is a benchtop mini lathe by its title; the listing has its weight. Compare the two numbers before you buy. Weight matters for lifting the lathe into place and for what the bench has to carry.

It also matters in a less obvious way. A lathe cuts by holding a tool against a spinning part, and the cutting force goes into the bed. A heavier bed on a rigid bench takes that force without moving. A very light lathe on a light bench can chatter, which leaves ridges on the finish. Owner reviews are the evidence on this, so read what VEVOR owners say about rigidity and backlash. Whichever machine you buy, bolt it to the bench or a stand rather than leaving it loose.

If the G4000 has to roll, our rule of weight times 1.3 gives 382 lb, and the WEN 500 lb base covers it. Check the mobile base sizing calculator with the VEVOR weight from its listing. The VEVOR 72 in workbench lists a 3000 lb load capacity in its title, though how that rating is meant to be used is on the listing.

The G4000 lists 9 A at 120V. At 125 percent that is 11.3 A, so a 15 A breaker and 14 AWG copper under the 60 C column of NEC Table 310.16. Our engine's NEC table calculation for a 30 ft run says 20 A on 12 AWG. A licensed electrician should confirm the circuit from the nameplate. The VEVOR title says 550W; the voltage and amps are on its listing, so size from those. A 550W motor is smaller than the 3/4 HP of the G4000, and that is about 0.74 HP by arithmetic, so the two motors are closer than the sizes suggest.

Keep either on a dedicated circuit, not one shared with a compressor or a heater, and see the workshop amps calculator. A lathe is loud when it cuts, so wear hearing protection and safety glasses. Chips are sharp and hot. Keep long sleeves rolled, keep hair back, and take the chuck key out before you start.

G4000 if you want the bigger envelope and a machine you can plan a bay around; VEVOR 7 x 14 if the budget is tight and your parts are small. The G4000 gives 8-3/4 in over 19 in, 16 x 37 in on the floor and 294 lb. The VEVOR gives variable speed, a digital display and a lower tier, with everything else on its listing. List your biggest part first, then choose, and have a licensed electrician confirm the circuit.
