The past few weeks have been quite a test of the youtube algorithm, nowhere near cracking it but now I’m going to try four uploads a day instead of 3, with one going out in the middle of the night when traffic is dead on my channel. That’s what all these shorts are for and of course, lots of projects ongoing so it isn’t difficult generating content for these shorts.
The Perfect CNC?
Wire EDM is one of the cleanest CNC machining processes. It cuts underwater with a continuously fed wire, producing no chips, very little noise, and exceptional accuracy. The tradeoff is speed, with feed rates often measured in just a few millimeters per minute. When precision matters most, Wire EDM is hard to beat.
Is This CNC?
Most people think CNC only means machine shops, but CNC is everywhere. I test a laser, plasma table, router, welder, bandsaw, and even an office printer to reveal which machines are truly CNC. The results might surprise you, and explain why I always ask, “What kind of CNC experience?”
Stop Measuring Every Cut
One accurate cut can save time on every piece that follows. Use your first finished piece as a master reference instead of measuring every section individually. This common fabrication technique keeps parts consistent, reduces measuring errors, speeds production, and prevents small differences from adding up across the entire project.
You’re Doing This Too Soon
Lamacoid is one of the easiest materials to engrave on a CO₂ laser, producing crisp edges, clean engraving, and very little smoke. It’s widely used for industrial nameplates, electrical labels, and equipment tags. One tip: let the exhaust run a few extra minutes after cutting to clear lingering plastic fumes before opening the laser.
Start With This Cut
A well-planned cut list saves time, material, and frustration. Before cutting steel for this custom welding cart, I organize every part and work from the longest pieces to the shortest for maximum flexibility. This simple fabrication habit reduces waste, improves accuracy, and makes any steel project more efficient from start to finish.
Perfect Tube Prep
Perfect tube prep starts before welding. After cutting square tubing, flatten the saw-cut end with a belt sander, then deburr the inside and outside edges with an angle grinder or flap disc. Add a slight bevel on thicker material for better penetration. Proper prep improves fit-up, weld quality, and saves time during fabrication.
Why Inserts Have A Hole
Ever wonder why carbide inserts have a hole in the middle? It’s more than just for the screw. The hole helps precisely locate and seat the insert in the tool holder, maintaining cutting accuracy every time it’s indexed. This simple design improves precision, consistency, tool life, and surface finish across many indexable cutting tools.
Avoid a costly mistake…
Good welds start before you strike an arc. Clean fit-up, removing mill scale, and deburring improve penetration and weld quality. For my fabrication projects, I use FCAW-S (flux core) for strong tack welds, then finish with 1/8-inch E7018 stick electrodes for maximum strength and clean, professional-looking results.
Skip This, Regret It
Every fabrication project starts with proper preparation. After cutting the steel tubing, I deburr the edges and remove mill scale from the weld areas using a belt sander. Clean metal improves weld quality, penetration, and fit-up. This custom welding cart build covers every step, from material prep to final assembly.
4 Stages of Carbide Wear
When should you replace a carbide insert? This Short shows the four stages of insert wear, from a sharp cutting edge to heat discoloration, excessive wear, and chipped corners. Knowing when to rotate or replace inserts improves surface finish, extends tool life, and protects your machine across almost any CNC application.
Stop Wasting Steel
A good cut list saves material and money. For this custom welding cart, I cut every part from a single 144-inch length of 1.5-inch square tubing, leaving just one inch of scrap. Careful planning reduces waste, lowers costs, and keeps fabrication projects efficient from the very first cut.
Plans Change. Adapt.
No cut list is perfect. While laying out steel for this custom welding cart, I found a better way to optimize the cuts and improve material yield from the same 144-inch tube. Taking a few minutes to rethink your layout can reduce waste, lower costs, and make every fabrication project more efficient.
This Ruins Perfect Nameplates
Some lamacoid sheets have a subtle surface grain. Rotate labels to save material, and the finished parts may have mismatched grain that becomes obvious after installation. Taking a moment to align every label the same direction creates a cleaner, more professional result without adding any extra laser cutting or engraving time.
Ditch Spring Clamps
Removing mill scale doesn’t have to be slow. This simple shop fixture securely holds 1.5-inch square tubing without spring clamps, making it easy to grind, remove, and load the next piece in seconds. Small workflow improvements like this save time, reduce repetition, and make fabrication projects faster and more consistent.
10 Second Laser Focus
Proper laser focus is essential for clean cuts and sharp engraving. This video shows how a Trotec laser uses a simple focus key to set the correct focal distance in seconds. Taking a moment to focus the laser improves accuracy, consistency, and overall cutting quality on a wide range of materials.
Should I Replace It?
A torn sanding belt doesn’t always need replacing. Sharp metal burrs can tear the paper backing, but minor edge damage often has little effect on performance. Knowing the difference between normal wear and a worn-out belt helps you get more life from your abrasives while saving time and money in the shop.
LEAVE THE BURRS
Not every burr needs to be removed before welding. Cleaning the outside edges and grounding surfaces is usually enough for strong, consistent welds, while small burrs inside square tubing rarely affect the finished result. Focusing on the preparation steps that matter saves time without sacrificing weld quality.
Different Trade. Different Footwear.
The best safety footwear depends on the job. I wear steel toe shoes for machining and breathable work boots for welding and fabrication, where sparks and hot slag are common. The right footwear improves comfort, reduces fatigue, and protects your feet, making it one of the best safety investments in any shop.
Metal Doesn’t Lie
Heat changes metal, whether you can see it or not. Welding teaches heat and distortion, while machining measures those changes with precision. Neither trade is better, they simply work to different tolerances. Learning both gives you a deeper understanding of how metal behaves and how to build more accurate, reliable parts.
Different Weld. Different Gloves.
Choosing the right welding gloves depends on the process. Thin TIG gloves provide better dexterity, while thicker gloves offer the heat protection needed for MIG, flux core, and stick welding. Using the right gloves improves control, reduces fatigue, and keeps your hands better protected during fabrication.
Save Your Ear Canal
Hearing protection matters. After wearing earplugs for 10-hour welding shifts, I found silicone earplugs more comfortable than foam for all-day use. The right hearing protection helps reduce fatigue, improves comfort, and protects your hearing while working around welders, grinders, CNC machines, and other loud equipment.
Good Work Looks Slow
Great work isn’t about speed, it’s about precision. The best machinists and welders take their time with setups, measurements, and fit-up to avoid mistakes and rework. Careful preparation leads to better quality, less waste, and greater efficiency. In manufacturing, working deliberately is often the fastest path to consistent results.
