Metal Lathe vs. Wood Lathe: The First Decision
The lathe category on ToolGalaxy spans both wood lathes and metal lathes, and these are fundamentally different machines. Wood lathes spin the workpiece while you apply hand-held gouges and chisels to shape it. Metal lathes use a carriage, compound rest, and leadscrew to feed a cutting tool with mechanical precision for threading, boring, and holding tight dimensional tolerances. Speed range reflects this divide: the JET JWL-1015VS wood lathe tops out at 3600 RPM on a 4-amp, 0.5-HP motor, while the Proxxon 27110 runs to 20000 RPM for micro-scale metalwork and watchmaking components. If your projects involve bowls, spindles, furniture legs, or decorative turnings, you want a wood lathe. If you need to cut threads, reduce shaft diameters, or bore precision holes in metal stock, you need a metal lathe with its full carriage-and-leadscrew system. Attempting metalwork on a wood lathe is unsafe and will likely destroy bearings and ways. Be clear on your material before comparing any other spec.
Swing and Between-Centers Distance: The Two Critical Measurements
Every lathe is defined by two capacity numbers. Swing is the diameter of the largest workpiece that clears the bed rails without hitting them; technically it is twice the distance from the spindle center to the top of the bed. Between-centers distance is the maximum length you can turn when the workpiece is supported at both the headstock and the tailstock. The JET JWL-1015VS encodes both in its model name: 10 inches of swing and 15 inches between centers. The JET 719200 weighs 121 lbs and runs the same 115-volt corded platform but with a 1-HP motor, indicating it supports a larger swing, typically in the 12-inch class. The Delta 46-460 has a 36-inch bed length measurement in its specs, which directly limits between-centers capacity, and at 12 amps on 110 volts it is built for a dedicated shop circuit. Before buying, measure your largest intended blank. Add at least 2 inches of clearance to the swing spec to avoid tight fits, and confirm the between-centers distance handles your longest planned project, whether that is a table leg, a lamp post, or a long-grain bowl.
Motor Power, Amperage, and Low-Speed Torque
Motor power determines what diameters and species you can rough without stalling. Amperage is the most reliable comparison point when horsepower is unlisted. The WEN 3424T draws 4.5 amps on AC and weighs 70.3 lbs, placing it in the entry segment where actual horsepower is roughly 1/3 to 1/2 HP based on the draw. The JET JWL-1015VS is a listed 0.5-HP model pulling 4 amps at 115 volts; adequate for spindle work and blanks under 6 inches, but owners report slowdown on dense hardwoods above 8 inches diameter. The JET 719200 doubles to 1 HP, which handles larger bowl blanks and hard species like walnut and maple with noticeably less speed loss under load. The Laguna Tools Revo Lathe lists a 2-HP induction motor running at 1725 RPM, sized for large-diameter production work where consistent torque at slow speeds matters. Higher amperage at the same voltage means more torque is available at low RPM, which is the real constraint during heavy roughing cuts. A lathe that stalls under load wastes time and strains the motor windings.
Variable Speed vs. Step-Pulley Systems
Variable-speed drive systems let you dial in exact RPM without stopping the machine to shift a belt. The JET JWL-1015VS carries VS in its model name to signal this feature, and its 3600 RPM top speed is accessible across a continuous range rather than fixed steps. This matters when you move from a heavy roughing pass at 500 RPM to a fine finish cut at 2000 RPM on the same piece, since you can adjust without powering down and repositioning a belt. Step-pulley lathes require you to stop, open the belt guard, lift the belt to a different pulley groove, and restart. The WEN LA3421 at $149.91 and the WEN 3424T at $362.29 are AC-powered benchtop models that use step-pulley or limited-range drive to keep costs low. For a hobbyist who sets up each session at one speed and turns similar-sized blanks, a step-pulley lathe is a practical choice. For anyone who switches frequently between spindle turning and bowl work, or who needs to match a specific surface footage rate for different materials, the variable-speed premium is justified in time saved and finish quality.
Bench-Top Models vs. Floor-Standing Lathes: Weight and Stability
Heavier lathes vibrate less, and vibration is the enemy of clean tool control and smooth finishes. The JET 719200 weighs 121 lbs versus the WEN 3424T at 70.3 lbs and the JET JWL-1015VS at 72.6 lbs. That extra cast-iron mass on the JET 719200 translates directly to reduced chatter, longer tool-edge life, and better surface quality on interrupted cuts across knots or figure. The Delta 46-460 is a corded 110-volt machine measuring 36 inches long by 11 wide by 17.75 tall and draws 12 amps, placing it firmly in the floor-standing or heavy bench category that requires a dedicated 15-amp to 20-amp circuit. Lighter benchtop models like the WEN LA3421 at $149.91 and the WEN 3424T are adequate for pens, small bowls under 8 inches, and spindles, but verified owner reviews consistently note the benefit of rubber feet or bolt-down mounting to reduce movement during heavier cuts. If your shop allows a floor-standing unit or a heavily bolted-down bench model, the additional rigidity repays the investment in finish quality on every piece you turn.
Budget Tiers: What the Data Shows Across $150 to $3,649
The lathes in this section span a wide price band, and each tier delivers a genuinely different capability level. At $149.91 the WEN LA3421 runs on AC at 3200 RPM with basic step-speed control, rated 4.3 stars across 252 reviews, and is realistically limited to pen turning, bottle stoppers, and small spindles. The $362.29 WEN 3424T steps up to 4.5 amps and 3400 RPM with 296 reviews at 4.5 stars, handling modest bowl blanks. At $714.99 the JET JWL-1015VS earns 4.7 stars from 105 owners and brings genuine variable-speed control, a 0.5-HP motor, and JET's reputation for accurate headstock bearings into the sub-$750 tier. The JET 719200 at $989.99 is the category's most-reviewed lathe at 663 reviews and 4.4 stars, a signal that a large number of buyers have validated it at its 1-HP, 115-volt configuration. The Delta 46-460 at $1,199.99 adds 12-amp power and a full-length bed for $200 more, rated 4.3 stars across 338 reviews, and the Laguna Tools Revo Lathe at $3,649 sits in a class for production woodturners who need the full 2-HP induction motor and 18-inch or 36-inch capacity. Match your budget tier to the size of work you actually plan to produce, not the size you might aspire to someday.
Common mistakes to avoid
- Buying a lathe with insufficient swing for planned projects because price was the only filter used, then discovering the workpiece physically cannot fit over the bed.
- Assuming any lathe handles both wood and metal, when the two machine types differ in bed design, speed range, carriage systems, and safe operating practice.
- Overlooking between-centers distance when planning longer pieces like table legs or lamp posts, and finding out the tailstock runs out of travel mid-project.
- Purchasing a lightweight benchtop model without accounting for vibration, then spending extra on after-market rubber feet, bolt-down hardware, or concrete blocks to manage chatter.
- Ignoring motor amperage and assuming all listed top-RPM figures are achievable under actual cutting load, which is rarely true at maximum speed on a light motor.
- Not verifying available circuit amperage before buying a 10-amp to 12-amp corded model like the Delta 46-460, which needs a dedicated 15-amp to 20-amp shop circuit to run safely.
Frequently asked questions
What does swing mean on a lathe, and why does it matter?
Swing is the diameter of the largest workpiece that can rotate over the bed without hitting it. It is twice the distance from the spindle centerline to the top of the bed rails. A lathe with a 10-inch swing, like the JET JWL-1015VS, can turn a blank up to 10 inches in diameter. If you buy a lathe with less swing than your intended workpiece diameter, the piece physically will not clear the bed.
Can a wood lathe be used to turn soft metals like aluminum?
No, not safely. Wood lathes lack the carriage, leadscrew, and rigid headstock bearings that metal cutting requires. Attempting to cut metal on a wood lathe risks damaging bearings, deflecting the unsupported tool into the workpiece, and creating a serious safety hazard. If you need to work metal, look at dedicated metal lathes rather than adapting a wood turning machine.
Is variable speed worth the extra cost over a step-pulley lathe?
Yes for most active users. Variable speed, as found on the JET JWL-1015VS, lets you adjust RPM during a turning session without stopping to shift a belt. This matters most when moving from heavy roughing to finish cuts, when changing between large-diameter bowl work and small-diameter spindle work, or when the material requires a specific surface footage rate. For a hobbyist who turns one type of project at a consistent size, a step-pulley lathe at a lower price point is a reasonable tradeoff.
How heavy should a lathe be for stable benchtop use?
Based on the specs in this section, 70 lbs is the practical floor for benchtop stability during moderate cuts. The JET JWL-1015VS at 72.6 lbs and the WEN 3424T at 70.3 lbs both benefit from bolt-down mounting, according to verified owner reviews. The JET 719200 at 121 lbs sits firmly and noticeably reduces vibration and chatter compared to lighter models in the same class. For heavy bowl blanks or interrupted cuts, the heavier the machine the better.
What is the difference between between-centers distance and bed length?
Bed length is the total length of the ways or rails on the lathe frame. Between-centers distance is the usable turning length when the tailstock is moved to its furthest travel position away from the headstock. Between-centers distance is always shorter than bed length because the headstock and tailstock each take up space. The Delta 46-460 has a 36-inch bed measurement in its listed dimensions, but actual between-centers capacity would be somewhat shorter. Always use the between-centers spec, not bed length, when evaluating whether a lathe fits your project.
Which lathe from this section is best for a first-time buyer on a limited budget?
Based on specs and verified owner reviews, the WEN 3424T at $362.29 offers a practical entry point: 4.5-amp AC power, 3400 RPM, 70.3 lbs of mass, and 296 reviews at a 4.5-star rating. It handles small to mid-size spindle and bowl work without the complexity of a larger machine. The WEN LA3421 at $149.91 is cheaper but limited to very small projects. If budget allows a step up, the JET JWL-1015VS at $714.99 adds variable speed and a stronger brand reputation for bearing quality, reflected in its 4.7-star rating.
