Comprehensive Beginner's Guide to Sheet Metal Armour Making

Opportunity Analysis:

User Need: The user, new to making armor, is struggling to find clear and detailed information on using sheet metal for this purpose. Comments show confusion about the right metal thicknesses for different applications (like SCA, LARP, and display), types of metal, and basic techniques. This points to a real need for a comprehensive, easy-to-understand resource for beginners.

Product Suggestion:

A "Beginner's Guide to Armour Making with Sheet Metal." This could be delivered as:

  1. A detailed eBook or physical book.
  2. An online course with video modules and downloadable resources (patterns, checklists).
  3. A dedicated website with structured articles, tutorials, and potentially a premium section.

Key Content Modules for the Resource:

  • Module 1: Understanding Sheet Metal for Armour

    • Types of Metal: A thorough explanation of suitable metals (e.g., mild steel (1018, A36), spring steel (briefly for advanced users), stainless steel, aluminum). Pros and cons of each for armor (workability, weight, protection, cost).
    • Sheet Metal Gauges and Thicknesses: A clear guide to understanding gauges and their millimeter equivalents.
    • Recommended Thicknesses Chart: Specific thickness recommendations for various armor pieces (helmets, breastplates, pauldrons, vambraces, greaves) tailored to different end-uses (SCA heavy combat, LARP, display/costume). Reference SCA minimums where applicable but also offer best-practice advice.
    • Sourcing Materials: Advice on where to purchase sheet metal (online suppliers, local steel yards, considerations for scrap for practice).
  • Module 2: Essential Tools for the Beginner Armorsmith

    • Hand Tools: A detailed list and usage instructions for hammers (ball-peen, cross-peen, planishing, riveting), snips (aviation, straight), files, chisels, center punch, clamps, measuring tools.
    • Forming Surfaces: Options for anvils, stakes, dishing forms (e.g., wooden stump, sandbag, simple steel forms).
    • Basic Power Tools (Optional but helpful): Angle grinder (for cutting and grinding), drill/drill press.
    • Safety Equipment: Emphasis on PPE (gloves, eye protection, hearing protection, respiratory protection).
  • Module 3: Fundamental Cold-Working Techniques

    • Pattern Making & Transfer: How to create and transfer patterns to metal.
    • Cutting Sheet Metal: Techniques for using snips, chisels, and angle grinders safely and effectively.
    • Basic Shaping:
      • Dishing/Sinking: Creating concave shapes.
      • Raising (Simplified): Creating convex shapes.
      • Planishing: Smoothing and hardening the metal surface.
    • Edge Finishing: Deburring and smoothing edges.
    • Drilling and Riveting: Techniques for clean drilling, types of rivets, and proper riveting methods for strong joints.
  • Module 4: Beginner Armour Projects (Step-by-Step)

    • Project 1: Simple Vambrace (forearm guard).
    • Project 2: Basic Knee Cop or Elbow Cop.
    • Project 3: A simple, non-articulated helmet component (e.g., a skullcap).
    • Include downloadable patterns and clear, illustrated/video instructions.
  • Module 5: Finishing and Maintenance

    • Cleaning, Sanding, and Polishing Techniques.
    • Rust Prevention Methods (oiling, bluing, painting).

Expected Benefits & Revenue Streams:

  • Direct Sales: Revenue from selling the eBook, online course, or premium website access.
  • Target Audience: Blacksmiths looking to expand their skillset, historical reenactors (SCA, HEMA, other historical groups), LARPers, cosplayers, prop makers, and general metalworking/DIY hobbyists.
  • Affiliate Marketing: Potential to partner with tool suppliers or metal distributors for affiliate commissions on recommended products.
  • Community Building: An online course or website could foster a community, leading to demand for intermediate/advanced courses or specialized workshops.
  • Establish Authority: Become a go-to resource for beginner armor makers, potentially leading to other opportunities (e.g., custom tool design, consulting).

This resource directly addresses the identified knowledge gap, providing practical, actionable information that beginners in armor making are actively seeking.

I've been forging for a good bit now and I want to try to make armour finally. After doing some research everyone says to use sheet metal, but they don't give any more information than just "

I think the SCA requires 14 gauge or 2mm for armor thickness for heavy fighting. Double check that though, it could have changed and I could be remembering incorrectly. Also be careful beca

SCA minimum for helmets is .065 iirc, which is usually the thickness of unshaped 16 gauge. I think a 16 gauge helmet is asking for brain damage in the long term though, so for multi-plate hel

Armour is a seperate, but related skill set. 90% of it you can do cold just fine. As far as thickness goes that depends on what you want to use it for and what piece it will be. For learnin

For your first time? I would recommend using the cheapest shit you can find. And I do mean shit. Cut-offs? Check. Clearance sale with rust? Check. Dug out of a scrap pile or made out of road
u/Kheltosh
Traditionally, everything from wrought iron to medium carbon steel was used. The helmets were roughly 2 mm and the body armor was roughly 1.5 mm at the thickest (chest plate, front of the hel

Well it's important to remember the thicker the tougher and to not make it too heavy or train to deal with it. Also make sure you keep in mind mobility and flexibility. Steel is stronger and
