How to Fix Common Angle Grinder Motor Problems (DIY Fix)
When you are mid-way through a heavy beveling job on half-inch plate, the last thing you want to hear is the rhythmic “thwack” of a dying motor or the acrid…
Metalworking often involves resolving unexpected issues, whether it is a machine malfunctioning mid-job or a weld joint refusing to cooperate. Problem-Solving Case Studies is dedicated to intermediate and advanced fabricators who need systematic, logical approaches to troubleshooting. This category breaks down specific technical challenges and documents the exact steps taken to diagnose, repair, and resolve them.
Our case studies cover a broad spectrum of workshop problems. This includes diagnosing electrical faults in older machinery, identifying the root causes of weld defects like porosity or cracking, fixing alignment issues on lathes and mills, and overcoming geometry challenges in complex weldments. We emphasize a methodical approach to troubleshooting: observing symptoms, isolating variables, testing hypotheses, and implementing permanent fixes.
By reading these real-world examples, you will develop a stronger diagnostic mindset for your own shop. Each article provides technical explanations of the physical and mechanical principles at play, helping you understand why a particular solution worked. Whether you are dealing with a finicky machine or trying to correct a challenging fabrication defect, these case studies offer practical, technical guidance to help you get your project back on track.

There is a specific rhythm to a productive shop. It is the sound of a bandsaw finishing a cut, the hum of a welder, and the predictable “thunk” of a…
When you spend your days chasing 0.002-inch tolerances on a lathe or trying to eliminate the last bit of porosity in a critical TIG weld, you develop a sixth sense…
I remember standing over a horizontal bandsaw in a drafty shop about twelve years ago, watching a piece of 4-inch mild steel chatter so hard it sounded like a machine…
I have spent the last 15 years inside fabrication shops, often hunched over a machine trying to figure out why a process that worked perfectly yesterday is failing today. One…
I’ve spent the better part of two decades in shops where the difference between a successful project and a costly failure often comes down to what you can’t see. Early…
I have spent the last 18 years walking the concrete floors of fabrication shops, and if there is one thing I have learned, it is that heat is often the…
I have spent nearly two decades in fabrication shops, and I have learned that heat is the silent enemy of precision. On a Tuesday in mid-July, I was working on…
I have spent the last 15 years in fabrication shops, often tucked inside cramped frames or reaching up into the skeletal structures of industrial mills. There is a specific kind…
I remember standing over a 20-foot aluminum marine manifold years ago, watching a perfectly straight assembly turn into a banana in under twenty minutes. I had followed the prints, but…
