Metal Lathe Buying Guide
Choosing the right metal lathe means matching machine size, precision, and features to your actual work. Here is what matters most:
Lathe Size: Swing and Between Centers
Mini Lathes (7x10 to 7x14)
Maximum 7-inch swing and 14-inch capacity. Best for model engineering, small parts, and learning fundamentals. Inexpensive to own but limited — cannot turn large or long workpieces. Popular for watchmaking, jewelry, and electronic component work.
Benchtop Lathes (9x20 to 10x22)
The sweet spot for most home machinists. Handles automotive parts, bushings, shafts, and most hobby work. Fits on a sturdy bench or dedicated stand. The Grizzly G0752Z and JET BD-920W live here and represent the best balance of capability and footprint.
Full-Size Lathes (13x40 and larger)
Required for gunsmithing barrel work, longer shafts, and production parts. Typically floor-standing, very heavy, and require 240V power. Best for serious machinists with dedicated shop space and specific projects that exceed benchtop lathe capacity.
Spindle Bore
Spindle bore determines what stock you can pass through the headstock for turning:
- 3/4-inch bore: Common on small benchtop lathes. Limits bar-through work to 3/4-inch diameter stock.
- 1-inch bore: Handles most pistol barrel blanks and common round bar stock. The Grizzly G0752Z has a 1-inch bore.
- 1.5-inch bore: Standard on full-size machines. Accommodates most rifle barrel blanks without outside support.
- 2.5-inch bore: Industrial lathes only. Required for large-diameter tube stock and specialized applications.
Gunsmithing Tip
If gunsmithing is a primary purpose, prioritize spindle bore over swing. A 1.5-inch bore lets you pass a #1 contour rifle barrel blank through the headstock for threading, crowning, and chamber work without needing a barrel vise.
Headstock and Speed Range
Spindle speed range determines what materials and operations you can perform:
- Low speed (50-500 RPM): Large-diameter turning, threading, knurling, and heavy cuts. Essential for anything over 4 inches in diameter.
- Mid range (500-1,500 RPM): General turning of steel, aluminum, and brass in typical diameters.
- High speed (1,500-3,000+ RPM): Small-diameter work, finishing passes, and non-ferrous materials like aluminum and plastics.
Variable-speed (VS) electronic speed control is a significant convenience advantage over gear-change lathes for frequent speed adjustments during a job.
Carriage, Cross-Slide, and Lead Screw
The carriage system determines how precise your threading and turning will be:
- Lead screw accuracy: Better lathes have hardened and precision-ground lead screws. Look for less than 0.001-inch per foot lead screw error for precision work.
- Quick-change gearbox: Allows setting thread pitch and feed rate with levers rather than changing gear sets. Standard on quality benchtop and all full-size lathes.
- Carriage lock: Locks the carriage for facing operations. Often missing on cheap lathes; critical for accurate face work.
- Compound rest: Allows angled cuts for tapers and chamfers. Quality of the compound rest affects surface finish on taper cuts.
Weight and Rigidity
Lathe weight directly correlates with rigidity, vibration damping, and surface finish:
- Under 200 lbs: Mini and small benchtop lathes. Requires a very sturdy bench and can still vibrate at high speeds or heavy cuts.
- 200-400 lbs: Quality benchtop lathes. The JET BD-920W at 290 lbs and Grizzly G0752Z at 230 lbs are in this range.
- 400-800 lbs: Full-size benchtop and smaller floor-standing lathes. Significantly better finish and chatter resistance.
- 800 lbs+: Serious floor-standing machines like the South Bend SB1001. Industrial rigidity for production work.
