JET BDB-929 9 x 29 Belt Drive Bench Top Lathe

Description

Cut precision instrument bushings and model fittings on common 115V wall outlets without running heavy subpanels. The JET BDB-929 Belt Bench Lathe gives hobbyists and gunsmiths compact turning across a 9in swing and 29in centers. A 0.75HP motor provides 6 belt speeds up to 2,000 RPM. Belt drive runs quiet, though step pulleys require manual belt shifting.

Fine-grain gray cast iron forms the lathe bed casting, ground with precision V-ways to guide carriage travel. Flame hardening protects the ways from swarf abrasion during steel turning passes. The 0.75HP single-phase motor runs on 115V power, pulling 9 FLA at continuous speed. Belt drive sheaves transmit smooth torque to the headstock spindle. The lathe weighs 250 lbs on a compact bench stance of 44in by 20in.

Key Features of JET JT9-321379

Gunsmiths and model makers pick this belt-driven lathe to turn small brass pins, thread model bolts, and bore sleeve bushings. Check regional retail equipment stock to buy JET JT9-321379 units for compact hobby toolrooms.

• Six belt-driven spindle speeds from 130 to 2,000 RPM provide smooth rotary torque without gear train noise.
• Standard 115V single-phase electrical motor plugs straight into standard garage and basement wall outlets.
• Enclosed gear box provides feed selections for cutting 27 imperial thread pitches from 8 to 56 TPI.
• Manual tailstock barrel provides an MT2 taper with 1-9/16in of graduated feed travel for drilling.
• Compound slide rotates 360 degrees to turn short tapers, chamfers, and precise bevel profiles.
• Ground cross slide features dual brass gib adjustments to eliminate axis play on fine passes.
• Removable chip tray slides out from beneath the bed to speed up end-of-day shop cleanups.

Belt Drive Spindle Runout Data

Dial test indicators show spindle nose runout under 0.0004in TIR measured at the 1-1/2in 8 TPI threaded spindle nose. Take a 0.040in deep cut in 6061 aluminum at 1,100 RPM, and you get an ultra-smooth finish with zero belt slippage. Motor current stays at 4.2A under normal cutting loads. Bedway deflection under 200 lbs of carriage thrust measures less than 0.0003in. Spindle bearings run cool, rising just 18°F above room temperature after 2 hours.

Belt Drive Usability Maintenance Protocol

The belt tension release lever swings forward with 4 lbs of force, letting you walk the drive belt across pulley steps fast. Micrometer handwheel collars read in 0.001in increments for precise depth control. Do not buy this light bench lathe for heavy steel forging roughing or industrial oilfield pipe.

• Coat the bedways, cross slide, and tailstock barrel with ISO 68 way oil before work every morning.
• Inspect the rubber V-belt for surface cracking and proper tension every 60 operating hours.
• Clean fine chips from the half-nut threading lever gears every 30 days using a stiff brush.
