The Unsung Hero of the Workshop Whether you are a professional or a DIY hobbyist, you know the drill. Even for a simple project, you end up needing a mountain of tools. Carrying them one by one? That’s inefficient and exhausting. Imagine grocery shopping without a cart—terrible, right? That is why a “Rolling Tool Cart”…

A Flashback to a Hot Summer (Better Late Than Never) It is currently freezing cold outside. My hands are numb just typing this. However, looking at these photos brings back the sweaty nightmare from a past summer. Yes, this incident happened quite a while ago during the peak of a heatwave. I was too busy…
The Nightmare of “Over-Gluing” Low-viscosity super glue is a double-edged sword. Its ability to penetrate tiny gaps is unmatched, but it flows like water. We’ve all been there: you aim for a tiny drop on a delicate scale model or a fine jewelry piece, but the standard bottle nozzle dispenses a massive blob, melting the…
The Nightmare Scenario I typically spend my days modifying or repairing CNC machines. But sometimes, requests come in that make me want to run away. Today’s story is exactly one of those cases: Removing Broken Bolts. Ideally, I would avoid this task at all costs. But due to certain circumstances (and perhaps a bit of…
The “Bad Hair Day” of Wiring In this post, I want to share a simple, slightly “janky,” but surprisingly effective tip for crimping spade terminals, which are common in DIY projects. If you do any kind of electronics work, you know the struggle. You strip a flexible cable (especially those with hundreds of hair-thin strands),…
A Hard Lesson Learned: The Day My Extinguisher Failed There’s an old saying: “Experience is the best teacher.” But honestly? Some things are better left unexperienced. A fire is definitely one of them. When I was in my early 30s, a fire broke out in my neighbor’s warehouse. I spotted it early, grabbed my trusty…
The Most Annoying Repair is the “Simple” One In my line of work, I handle a lot of automation parts. Sometimes, surplus items pop up. I recently sold a tested, working Yaskawa Sigma-5 servo motor on a used parts forum. I confirmed it was working and shipped it, but a few days later, I got…
The Goal: Perfect Precision. The Problem: My Own Mistake. For my CNC project, I chose a Harmonic Drive (a type of strain wave reducer). Why? Because its unique mechanism—using a Circular Spline, a Flexspline, and a Wave Generator—provides near-zero backlash. This allows for the kind of ultra-precise angular control that other gear systems can’t touch….
