How to Fix the Stuff They Take Apart on Assembly Required

Tim Allen and Richard Karn test flamethrowers on the History show Assembly Required.

There are plenty of shows and streams available that show people building something, be it a new home, a historic weapon, or an anti-theft glitter bomb. Not too much entertainment deals in the real work of making good items keep working, even though a successful fix makes you feel like a combination secret agent, wizard, and superhero.

That’s why we were excited to see Tim Allen announce last year that he was teaming up with his Home Improvement costar Richard Karn and DIY star April Wilkerson to host a new DIY competition show. The big difference on Assembly Required is that contestants make their wild projects by disassembling, upgrading, or combining common household items—the kind of items we love to help people fix.

So we partnered with Assembly Required to provide contestants with some of the tools they might need to make tricked-out doghouses, maximalist lawn mowers, and DIY jacuzzis. You can spot our distinctive black-and-blue kits when the fixers unpack their projects, and occasionally during their hard work.

You can watch Assembly Required Tuesdays at 10 p.m. Eastern time on History or watch some full episodes on History’s website or in the History app. And you learn more about how to open up, tinker with, and repair the things you see on the show right on our site. Here are some of the devices and repairs we’ve seen featured on Assembly Required so far.

Flamethrower

Technically, the Boring Company’s device is named the Not-a-Flamethrower. Realistically, what it does is throw flames. We took ours apart, just in case you need to do that, too.

Lawn Mower

Repair guides and support for gas, electric, and human powered machines used to cut grass, whether push style, or ride-on.

While there are many models and brands, many of the inner mechanics of lawn mowers are fundamentally the same. If you’re careful about gas, blades, and the starting switch, there’s a lot to learn inside.

Coffee makers

You can learn a lot about the world from taking apart a coffee device, as our CEO once did. We’ve got guides to backflushing your espresso machine, swapping the O-ring on a Mr. Coffee, and even trading out the one problematic capacitor inside a Senseo II pod machine.

Soldering

Any time you’re hooking up power to something, be it a lamp or a tricked-out La-Z-Boy, you’re likely to encounter soldering. It can seem intimidating to mess with the stuff holding together wires and circuit boards—they did this at the factory! But once you get a little practice in, you’ll realize that you can mess with it, and save entire devices from the trash bin while doing so.
