Delta Homecraft 11″ Drill Press Model 11-120: A Classic Mid-Century Bench Drill for the Home Workshop
Introduction
The Delta Homecraft 11″ Drill Press Model 11-120 is one of the most iconic bench-mounted drill presses from the golden age of American woodworking machinery. Compact, precise, and beautifully engineered, it was built to serve the growing postwar community of hobby woodworkers and small professional shops.
Produced by Delta/Rockwell during the 1950s, this machine has become a collectible favorite—not just for its functionality, but for the craftsmanship and mechanical elegance it represents. Today, the 11-120 is often lovingly restored by enthusiasts who appreciate its enduring quality and timeless design.
History of the 11″ Delta Homecraft 11-120 Drill Press
The Model 11-120 emerged from Delta’s popular Homecraft line, first introduced in the late 1940s to provide serious woodworkers with professional-grade tools scaled for home use. These machines shared many design features with Delta’s industrial models but were more affordable and compact.
The 11-120 succeeded earlier models like the Delta DP-220, improving upon them with refinements such as a more robust quill assembly, a larger tilting table, and an updated belt guard design.
When the Rockwell Manufacturing Company acquired Delta in the mid-1940s, the 11-120 represented the perfect blend of old Delta precision and Rockwell’s modern production efficiency. By the mid-1950s, it was one of the most common Homecraft tools found in home shops, schools, and technical programs across America.
Manufacturer Background: Delta Specialty Company / Rockwell
Founded in 1919 by Herbert Tautz in Milwaukee, Wisconsin, the Delta Specialty Company began as a small operation producing woodworking jigs and accessories. Delta soon evolved into a leading manufacturer of full-sized woodworking machinery, setting a standard for accuracy and durability.
After its acquisition by Rockwell Manufacturing, the combined Rockwell/Delta brand became a powerhouse of American woodworking equipment. The Homecraft series (table saws, jointers, lathes, sanders, and drill presses) was aimed at the serious home hobbyist who wanted industrial quality at a manageable scale.
Design and Specifications
The Delta Homecraft 11-120 was a bench-top drill press designed for versatility, accuracy, and ease of operation. Its durable cast-iron frame, smooth spindle action, and adjustable table made it suitable for both wood and light metal work.
Typical Specifications:
- Drilling Capacity: ½″ in mild steel (larger in wood)
- Chuck Size: 0–½″ (Jacobs or Delta OEM chuck)
- Quill Travel: 3″
- Column Diameter: 2⅜″
- Table Diameter: ~8–9″, adjustable for height and tilt
- Spindle Speeds: 5 or 8 speeds via step pulleys
- Drive Type: Belt-driven, V-belt system
- Motor: ¼ to ½ HP, typically 1725 RPM
- Construction: Cast iron base, head, and table with steel column
The overall footprint was compact enough for bench mounting, making it ideal for garages, home shops, and school environments where space was at a premium.
Features of the Homecraft Line
The Homecraft series was designed for serious do-it-yourselfers in the postwar era. The 11-120 shared the same styling and engineering principles as Delta’s other Homecraft tools:
- Cast-iron precision for rigidity and vibration damping
- Interchangeable motor mounts across multiple Homecraft tools
- Compact footprint for small workshops
- Stylish industrial design with gray enamel finish and red Homecraft badge
- Affordable pricing without sacrificing accuracy
These qualities made the Homecraft brand synonymous with dependable, small-scale professional equipment.
Usage and Applications
The Delta 11-120 was a workhorse in its class—ideal for drilling wood, plastic, and nonferrous metals. Hobbyists used it for furniture making, cabinetry, and precision jig building. Schools adopted it widely for shop instruction due to its safety and reliability.
Its accuracy and steady quill made it capable of precision dowel holes, mortising attachments, and even light metal fabrication. With proper care, the 11-120 still performs admirably in modern hobby workshops.
Restoration and Maintenance of the Delta Homecraft 11-120
Restoring a Delta Homecraft Drill Press Model 11-120 is a rewarding project that returns this mid-century classic to full functionality while preserving its vintage character.
1. Disassembly and Cleaning
- Begin by photographing the drill press from all angles before disassembly.
- Carefully remove the motor, pulleys, table, and quill assembly.
- Degrease all parts using mineral spirits or a citrus-based cleaner.
- For rust removal, use Evapo-Rust, electrolysis, or light wire brushing to preserve original surfaces.
2. Bearing and Spindle Inspection
- The 11-120 uses high-quality ball bearings in the quill and pulley assembly.
- Check for play or roughness in spindle rotation—replace bearings if needed (commonly available replacements from suppliers like McMaster-Carr).
- Lightly lubricate all moving parts with machine oil during reassembly.
3. Table and Column Refinishing
- Remove surface rust from the table and column using 400–600 grit emery cloth or fine steel wool.
- Wipe clean and apply a protective wax or light oil coating to prevent rust.
- If the table has drill marks or pitting, they can be carefully resurfaced using a belt sander or mill file.
4. Paint and Badging
- Many restorers match Delta’s classic gray enamel finish using Rust-Oleum “Smoke Gray” or custom-mixed machinery gray.
- Preserve original Delta or Homecraft decals if possible—or replace them with reproduction decals available online (e.g., via VintageMachinery.org or Etsy sellers).
- Clean the red “Homecraft” badge gently using mild soap and a soft brush.
5. Electrical and Motor Restoration
- Inspect the motor wiring and switch for frayed insulation or corrosion.
- Replace the cord with a grounded three-prong type for safety.
- Bearings in the motor may need replacement—many ¼–½ HP motors use standard sealed bearings.
6. Reassembly and Calibration
- Reassemble the drill press, ensuring smooth quill travel and proper belt tension.
- Align the table to be square to the spindle using a machinist’s square.
- Adjust the depth stop for accurate drilling depth control.
A well-restored 11-120 can perform just as accurately as it did 70 years ago, and its solid feel often surpasses many modern lightweight drill presses.
