DAILY JOURNAL: Why does precision machining on a lathe require tighter tolerances than hand fabrication?
TODAY'S SCHEDULE:
Daily Journal & Attendance
Lathe Top Design Challenge Introduction
Process Overview Video
Lathe Safety Review & Setup
Begin Machining Operations
Clean-Up & Tool Accountability
Launch the Lathe Top Design Challenge - machine a spinning top to exact specifications using the lathe. CVHS standard: minimum 20-second spin time for an A (CHS only requires 8 seconds - we have higher standards).
VIDEO OVERVIEW: https://youtu.be/iaIL22lIOaQ
DIMENSIONS: See attached hard copy for exact specifications.
⚠️ PRECISION MATTERS: Tolerances must be tight - balance and surface finish directly affect spin time. ⚠️
💡 MACHINING TIP: Invisible preparation enables quality visible work - measure twice, cut once. Setup accuracy determines final performance.
BONUS OPPORTUNITIES:
Create technical drawing of your top design
Design and 3D print a custom storage case for your top
CHALLENGE CRITERIA:
A Grade: 20+ second spin time
Meets all dimensional specifications
Professional surface finish

🍩 No completed Google Doc = No donut
Grid paper keeps your angles accurate
Darker lines = better readability
These skills directly support your fabrication POPs
Shop access available after drawing session for approved projects
You're building the visual vocabulary needed to communicate fabrication ideas. Before cutting metal, you sketch the concept. Before welding assemblies, you visualize how pieces fit together. Isometric drawing = thinking in 3D.
METALS AGENDA: 10.23.2025
THURSDAY 10/23
DAILY JOURNAL: Why is accurate dimensioning critical when creating technical drawings? What problems occur when dimensions are missing or unclear?
CLASS INTRODUCTION:
Mr. McAteer will demonstrate isometric sketching techniques for POPs. Loose leaf paper and isometric grid paper available for those who need drawing support.
PRIORITY WORKFLOW:
PRIORITY 1: SolidWorks Lego Man Assignment
This is your primary task.
Complete the "Learn SolidWorks" Lego Man modeling assignment
Follow all dimensional specifications
PRIORITY 2: CNC Name Plaques
Start only after Lego Man is complete.

DAILY JOURNAL: What safety precautions are essential when using the powder coating oven? Why must the workspace be clean before powder coating?
Daily Journal & Project Status Check (10 min)
Powder Coating Station Setup (15 min)
Production Work: Plasma Signs → Powder Coating → Assembly → POP (65 min)
Students will work through a priority sequence based on project completion status. Move to the next task only after completing and submitting your current work.
If your plasma sign is complete and prepped:
Report to the powder coating station
Complete surface prep checklist with Mr. McAteer
Apply powder coat and cure in oven
Document with before/after photos
If powder coating is unavailable or you're waiting for oven time:
Complete Lego Man assembly project
Follow dimensional specifications from original assignment
Take final documentation photos
Submit via Canvas
LINK TO TEMPLATE FOR PLAN OF PROCEDURE (POP)
If all fabrication projects are complete:
Begin drafting your personal project POP
Reference the POP TEMPLATE from 10/16 agenda
Focus on: project sketch, bill of materials, step sequence
Parts must be completely clean and grease-free
Wear heat-resistant gloves when handling oven
Never open oven door during cure cycle
Work area must be clear of flammable materials
Powder coating requires a 30-35 minute cure cycle. Use this time productively—start your Lego Man assembly or sketch your POP project concept. Time management is a critical fabrication skill.
✓ Plasma signs are powder coated and curing/baking
✓ Lego Man projects are complete in Solidworks
✓ POP drafts show clear project vision with sketches
✓ All work areas are cleaned and organized before dismissal
DAILY JOURNAL: What are the primary safety concerns when testing a new piece of equipment like a powder coating system for the first time?

Today's focus is on developing a core fabrication skill: laying consistent beads with the MIG welder. Productive work is expected from all students, whether in the shop or the design lab.
Welding Group (Shop): Obtain a 4”x6” 12-gauge steel coupon and practice laying straight, consistent beads.
Design Group (Computer Lab): Continue working on the design for your CNC plasma name placard.
Expectation: We will rotate between activities. Stay on task in your assigned location until instructed to switch.
Outcome: End the period with either a completed welding practice coupon or significant progress on your CNC design file.
Today's focus is on effective design. We will translate your initial concepts into a functional digital file for the CNC sign project.
Systems Check: Log in, confirm virtual account access, and launch SolidWorks & Illustrator.
Design Principles: We will analyze examples of good versus bad sign design to establish clear standards.
Design Session: Begin creating the digital file for your CNC sign, applying the principles from our discussion.
Outcome: End the period with a saved preliminary design file.
