You don't have a soldering problem. You have a diagnosis problem.
Most home-based jewellery makers using handheld torches have spent years following checklists, watching tutorials, and still not knowing why their solder won't flow. The problem isn't your torch. It isn't your solder. It's that nobody has ever taught you how to read what's happening at the join.
The Diagnostic Framework Course changes that.
In four modules, you'll learn to look at your metal, your flux, your solder, and your heat — and know exactly what each one is telling you. Not follow a checklist. Read the evidence and fix the actual problem.
What you'll learn:
- How to shift from guessing to diagnosing — the mindset that changes everything
- How to read your prep: what your metal and join are telling you before you even pick up the torch
- How to read your materials: what your flux and solder behaviour is showing you in real time
- How to read your heat: what your flame and metal colour are communicating — and how to respond
This is for you if:
- You're a home-based maker using a handheld torch
- You've followed all the advice and still can't get consistent results
- You want to understand what's going wrong, not just try something different and hope
This is not for you if:
- You're looking for another checklist to follow
- You expect results from watching alone without putting in bench time
Meet your coach
I'm Linda Sandeman — a jewellery maker and soldering coach with 15 years at the bench and 10 years of teaching home-based makers.
I built the Diagnostic Framework because I kept seeing the same thing: students who weren't struggling with soldering — they were struggling with not knowing how to read what was going wrong. Once you learn to diagnose, everything changes.
I teach makers using handheld torches to read their metal, their flux, their solder, and their heat. Not follow a checklist. Understand what's actually happening at the join.`
