Måla metall – Chalk paint – Paint metal

Hello! These bar stools I tried Autentico hardwax oil on and I was pleased with the result It was very easy to use, it smelled pretty much, but it did not matter the smell went away after a while and the result was absolutely fantastic They were very orange on the top before but it […]

Cut metal easily! – DIY Power hacksaw

Hi I’m Emiel, The Practical Engineer, and today I’m making this drill powered metal hacksaw To power the saw with my drill I need to convert rotary motion into linear motion. And I’m doing that by making an axle that fits onto my drill That has a point ,off-center, that moves like this. And when […]

Burning Stuff With 2000ºF Solar Power!!

In a previous project I found a free tv and turned it into a giant solar scorcher. This shoots out a deadly beam of sunlight, that’s hot enough to abuse food, melt metal and burn things you probably shouldn’t. Today seemed like a good day to play with my Solar Scorcher. I positioned my frame […]

The Metal Melter

I’ve just modified this Microwave Oven Transformer into a dangerous little device. 800 amps of electrical current is about to be bad news for anything made of metal. Today I’m in the mood to melt some metal. This Microwave Oven Transformer used to be a dangerously high-voltage device, but I modified it so the voltage […]

✔ Minecraft: 10 Things You Didn’t Know About the Iron Golem

Iron golems can be constructed in more than two orientations! Iron golems have exactly 100 HP. This makes it the 3rd toughest mob, as the ender dragon has 200 HP and the Wither has 300 HP. Iron golems don’t take fall damage! It doesn’t even care.. You would think the last two facts made it […]

How to make a mini Hydrogen Generator / TUTORIAL

您需要準備這些東西 2個同尺寸的冰棒棍 在棍面上畫上鑽孔點 再叧一根棍面上重做一次 再穩穩的將兩根冰棍壓緊 鑽孔 鑽孔後就像這樣 每相隔一個孔鎖上一個螺絲並穿過兩冰棍 再換面重做一次 再螺面上焊上錫點(可視螺絲材質選用合適的錫) 換面重做一次 然後 再螺面錫點上焊上電線 現在 可以將導電模組放入玻璃瓶中 瓶蓋上要鑽一個合適孔徑的洞 拿出西藥房買的滴管組 切掉上端 將電線穿過瓶蓋開孔 再將滴管組的觀察室塞進孔中,盡量塞緊 再用熱融膠封口,確保氣體不外洩 鎖緊瓶蓋 再依據實際需求剪截滴管 在集氣瓶鑽2個合適大小的孔 將滴管末端由孔1塞入瓶中 一定要將管子穿到瓶底 再將裁剩的那截滴管由孔2穿入瓶內.不必穿太深 再以熱融膠封口 這時 可以倒入清水了 蓋上瓶蓋 取一些鹽加水攪均 再打開瓶1 (導電模組) 倒入剛才自製的鹽水(導電液) 要淹滿整個導電模組 鎖緊瓶蓋 現在可以將電線接上電源供應器了 調整輸出電壓為 2.1 伏特 現在 您會看到瓶內開始有汽泡產生 (泡泡測試)

Making a Rail Anvil Stand

The rail gets traced here to establish a template The outline is cut using a bandsaw The template fits over the rail in both directions Strips of 1/2″ plywood are cut on the table saw Plywood squares are cut The template is used to trace the outline onto each square Holes are drilled to help […]

Making an ARC Welder – Part 1 of 2

When I burned up the wires on my first Metal Melter, I decided to turn the transformer core into a stick welder. But one transformer wasn’t enough to actually make it weld anything. In this project we’ll be modifying 2 microwave transformers, because more transformers means more power. For this project I scavenged parts from […]

How to Make The Metal Melter

In a previous video I used a modified Microwave Oven Transformer as an electrical metal melter. In this video you’ll learn step by step how it was made, and what I’m using it for now. In a previous project, I found an old microwave in a dumpster and hacked it open to see what components […]
