Figuring away how to build a flatbed truck bed is a rite of passage for a lot of truck owners who require more electricity than a regular factory box may offer. Whether your own original bed is definitely rusted out, defeat to pieces, or even you just need a platform that will can actually manage odd-sized loads, going the DIY route is a strong way to get exactly what a person want without dropping five grand upon a pre-fabricated aluminium unit. It's a big project, certain, but it's mostly about careful measurement and a few decent welding skills.
Let's be honest: factory beds are great for groceries, but for real work, they're often in the way. A flatbed gives you that "load from any side" freedom that changes how you use your own truck. Plus, there's a certain satisfaction in looking at your rig and knowing you fabricated the back half your self.
Getting the particular plan and measurements right
Prior to you even contact a grinder, you need a plan. You can't just wing it when you're dealing with the particular structural integrity of your vehicle. The most important component of learning how to build a flatbed truck bed is understanding your own specific truck's body. Every manufacturer does things a little differently—some frames are flat, while other people have humps over the rear axle.
Begin by measuring the distance between cab and the particular end of the particular frame. You'll also need the width of the frame rails and the particular total width you want the finished bed to be. Usually, you would like the bed to be roughly simply because wide as your own mirrors or simply somewhat wider than the cab. Don't forget to measure the tire clearance. You require enough "up travel" so that when you hit a pothole with an insert of gravel, your tires don't break into the underside of your new deck.
Stripping the truck down
Now comes the messy component: taking the old bed off. This is usually just six or eight mounting bolts, but if a person live anywhere close to the salt belt, those bolts are getting to fight a person. Get a great penetrating oil and let it soak for a day time. If that doesn't work, don't become afraid to make use of a torch or a cutoff steering wheel.
You'll also have to deal with the particular fuel filler neck of the guitar as well as the wiring control. The filler throat is frequently attached to the side of the factory bed, therefore you'll need a plan to install that securely to your new flatbed later. For the wiring, just unplug the tail lights and move the harness out of the way. Do not cut the wires in the event that you can prevent it; it's much easier to use adapters or just rewire the plugs compared with how it is to trace a short in a chopped-up harness six months from now.
Fabricating the major frame
The particular "bones" of your flatbed are typically made from steel C-channel or even rectangular tubing. Almost all guys use 4-inch C-channel for the main runners (the parts that sit on the truck frame) and 3-inch channel or heavy-duty angle iron for the crossmembers.
Lay your primary runners out upon the truck framework first. It's a good option to put several rubber stripping or even treated wood coil spring spacers between the truck frame and your new bed body. This prevents metal-on-metal rubbing, which leads to rust and frustrating squeaks. Once these are arranged, a person can start spacing out your crossmembers. Most people space them about 12 to 16 inches aside. If you're preparation on hauling a heavy gooseneck trailer, you'll need to beef up the particular area directly over the axle along with extra bracing.
Welding it most together
This particular is where the particular project really begins to look like something. You need to tack every thing in place very first. Don't go intended for full beads best away, because the temperature from welding may warp the metal and make you along with a bed that's crooked. Check for squareness constantly. Measure corner-to-corner; if the diagonal measurements are the same, you're in good shape.
Once it's all tacked and block, go on and burn it in. Make sure your welds are usually deep and clean. This bed goes to be vibrating, bouncing, and holding weight for many years, so this isn't the particular place to practice your first-ever weldings. If you're not really confident in your welding, this is the time to call over a pal who is.
Choosing your decking material
When thinking about how to build a flatbed truck bed, the floor is where you have the most choices. You've basically got two primary options: steel dish or wood.
Steel plate (usually diamond plate) will be incredibly tough and looks sharp. It's great if you're sliding heavy equipment on and away from the bed. However, it's heavy, noisy, and gets extremely slick in order to rains or snows.
Wooden decking is a traditional choice for a reason. It's easier to replace in case you damage a board, and it's much quieter than metal. If you go with wooden, use something such as 2x6 pressure-treated pinus radiata or, if a person want to obtain fancy, some rough-cut oak. Just keep in mind that wood extends and contracts, therefore leave a small gap between your planks. You'll bolt these down to your own crossmembers using buggy bolts or specific floor screws.
Wiring and light
You can't just drive around without tail lighting, and this is often where people obtain stuck. Since you're building a custom made bed, you've obtained the perfect opportunity to upgrade to high-visibility LEDs. Most people build light boxes into the back C-channel to shield the lights from getting smashed when backing into issues.
You'll need blinkers, brake lights, and those small red clearance lamps if your bed is wide more than enough. Be sure you ground almost everything properly to the particular frame. Bad reasons would be the number a single cause of flickering lights on DIY flatbeds. While you're at it, bracket that fuel for filler injections neck we talked about earlier. It wants to have an incline so the gasoline actually goes directly into the tank with no splashing back with you.
The particular finishing touches
Before you call it up a day, you need to protect that will raw steel. In case you leave it bare, it'll be orange with rust simply by next Tuesday. You are able to go the DIY route with a good primer and a few heavy-duty implement color (the stuff they use on tractors), or you can take the entire bed to a shop to obtain it powder-coated or line-x'ed.
Don't your investment "extras" that make a flatbed useful. Risk pockets along the sides allow you to build removable wooden walls with regard to when you're trucking mulch or garbage. D-rings welded to the frame provide you solid tie-down points for connectors. And if you're feeling really productive, building a "headache rack" behind the cab is a smart move—it protects your rear window from whatever you've got in the particular back.
Is it worth the effort?
Learning how to build a flatbed truck bed is a serious commitment of period and sweat, yet the payoff is worth it. You end up with a truck that is vastly more capable compared with how it had been when this rolled from the set up line. Plus, in case you ever damage it or desire to add a tool box, you know exactly how it's assembled due to the fact you're the one which built it. Just take your period, measure three occasions before you cut once, and make sure your weldings are solid. Your truck will give thanks to you for it.
