Cut Steel with Hand Tools, Grinders, and Abrasive Wheels

A. Finished-Project Specification

Outcome: a complete set of mild-steel coupon blanks cut from the Chapter 4 cut list to the specified length, width, and squareness tolerance, with deburred handling edges, verified dimensions, and a completed cut-quality inspection record. This chapter does not bevel, joint-prepare beyond deburring, or weld any material.

B. Cutting Component Schedule

Component	Quantity	Cutting Tool	Cut Condition
Small hand-cut blanks	Per cut list	Hacksaw	Secured in a bench vise; hand-controlled travel
Larger or repeated blanks	Per cut list	Portable band saw	Secured in a vise or clamp; supported on both sides of the cut
Bench-cut blanks	Per cut list	Chop saw	Secured in the saw's integral vise; screens positioned around the spark path
Blanks requiring portable abrasive cutting	Per cut list	Angle grinder with approved cut-off wheel	Secured in a vise or clamp; two-hand grinder control

C. Material Takeoff

• Stock: identified mild-steel pieces carried forward from the Chapter 4 cut list, in the quantity and dimensions specified there.
• Cut-off wheels or saw blades: one or more replacement cut-off wheels or hacksaw/band-saw blades rated for the selected tool, stock material, and stock thickness, sufficient for the full cut list plus an allowance for wheel or blade wear.
• Marking supplies: soapstone or marker sufficient to mark every cut line and waste side on the full cut list.
• Consumables: none beyond cutting media and marking supplies; this chapter does not consume welding consumables.

Edge condition	Free of burrs, gouges, and excessive heat damage after deburring
Tool and wheel/blade condition	Inspected before use; no vibration, wobble, cracking, or unusual noise during the no-load check
Stock security	Every piece secured in a vise, clamp, or fixture, or supported against rolling and rotation, before the tool contacts material
Spark and drop-piece control	Spark path directed only into the approved collection area; offcut supported as the cut completes
Documentation	Tool, wheel or blade, material, dimensions, cut quality, defects, and corrective action recorded for the full set

E. Preparation — Cut List and Area Review

1. Review the cut list, stock dimensions, tolerances, material, and permitted tools. Confirm every piece on the list is accounted for before cutting begins.
2. Confirm the steel is identified and free from prohibited coating or contamination. Stop and resolve any unidentified, galvanized, plated, painted, or oily material before continuing.
3. Inspect the work area for spark, fire, electrical, and public-exposure hazards. Confirm the area remains within the Chapter 1 readiness boundary.
4. Set grinding screens and spark containment. Position screens around every powered cutting station before starting a tool.
5. Stage safety glasses, face shield, hearing protection, gloves, flame-resistant clothing, and footwear. Confirm PPE is on and correctly fitted before any tool is selected.

F. Tool Selection and Inspection

1. Select a hacksaw, portable band saw, chop saw, angle grinder, or other approved cutting tool for each cut. Base the selection on the piece size, quantity, and required control, not on convenience alone.
2. Do not select a tool merely because it is faster when it cannot control the stock safely. Reject a tool choice that cannot be paired with adequate securing for the piece at hand.
3. Inspect the selected tool, guard, switch, cord, handle, vise, base, and blade or wheel. Confirm every component is present, undamaged, and correctly assembled.
4. Verify wheel or blade type, size, speed rating, direction, and material compatibility. Confirm the rating meets or exceeds the tool's rated speed.
5. Disconnect power before installing or changing a wheel or blade. Confirm the tool is fully isolated before touching the mounting hardware.
6. Mount the wheel or blade with correct flanges, fasteners, and guard position. Confirm the guard remains positioned between the wheel or blade and the operator.
7. Allow a newly mounted abrasive wheel to run at safe no-load speed from a protected position. Stand clear of the wheel's plane during the check.
8. Stop for vibration, wobble, cracking, unusual noise, or damaged mounting. Do not proceed to cutting until the condition is corrected and rechecked.

G. Marking, Securing, and Cutting

1. Measure and mark cut lines from an approved reference edge. Use the same reference edge established for the piece in Chapter 4.
2. Mark the waste side of each line. Confirm the mark is visible from the operator's cutting position.
3. Support the stock on both sides as needed without pinching the wheel or blade. Confirm support does not close the kerf against the cutting edge.
4. Secure short or small pieces in a vise, clamp, or machine fixture. Confirm the piece cannot shift under cutting pressure.
5. Do not hold the workpiece by hand near the cutting path. Reposition the fixture or clamp rather than holding the piece by hand.
6. Position round stock against rolling and rotation. Use a V-block, clamp, or equivalent support for round sections.
7. Plan the body position, tool path, spark path, and drop-piece movement. Confirm the plan before the tool contacts material.
8. Keep others outside the spark and fragment zone. Confirm the area is clear before starting the tool.
9. Start the tool before contacting the material. Do not begin the cut with the blade or wheel already touching the stock.
10. Bring the wheel or blade into the cut gradually without binding or side loading. Avoid forcing the tool into the material.
11. Maintain stable two-hand control of portable tools. Keep both hands on the designated grip locations throughout the cut.
12. Do not twist a cutting wheel in the kerf. Keep the wheel traveling in a single plane through the cut.
13. Allow the tool to cut at its designed rate. Do not force the feed rate beyond what the tool and wheel or blade can sustain.
14. Stop if the stock shifts, the wheel binds, the guard contacts material, or sparks reach an unsafe area. Correct the condition before resuming the cut.
15. Support the offcut as the cut completes. Confirm the drop piece does not fall uncontrolled as the final material separates.
16. Place cut pieces in the marked hot-metal or cooling area. Treat every freshly cut piece as hot until verified otherwise.
17. Allow the tool to stop fully before setting it down. Do not set down a tool with a coasting blade or wheel.
18. Disconnect or isolate the tool before adjustment. Confirm isolation before changing any setting between cuts.

H. Deburring, Inspection, and Documentation

1. Inspect each cut for length, squareness, burrs, gouges, excessive heat damage, and edge quality. Compare each measurement against the cut list tolerance.
2. Deburr edges with an approved file or grinder. Remove sharp handling edges along the full length of each cut.
3. Remove sharp corners that create handling hazards while preserving required dimensions. Do not remove material beyond what the handling-hazard correction requires.
4. Measure finished blanks and mark rejected pieces. Identify any piece outside tolerance for remaking rather than forcing it into later fit-up.
5. Clean metal dust and abrasive debris using the approved method. Clear the cutting station before moving to the next tool or piece.
6. Inspect for hidden sparks or smoldering material. Confirm the cooling area and surrounding surfaces are clear before leaving the station unattended.
7. Document tool, wheel or blade, material, dimensions, cut quality, defects, and corrective action. Complete the cut-quality inspection record for the full set before proceeding to Chapter 6.
