A lot of you occasional metalworking people out there want to know how to make your own sheet metal bender. That is understandable, if you only need a metal bender on a rare occasion - or perhaps if you are the type of person that has to build everything themselves. If you belong to the latter, I can tell you that making your own bending machine will probably not be worth it in terms of the hours you are going to put into it, as a commercially available sheet metal bending brake really isn't very expensive - a couple of hundred dollars buys you a very nice machine indeed, and they can be had cheaper still.
Metal Saw
But alright, you have made up your mind to build a sheet metal brake yourself, so let us look at what goes into a job like that. The sensible thing is to start by looking at how a commercial metal bending machine works, so try to arrange to go and look at one in person. Bring a digital camera and take loads of pictures for future reference, and if you can, try to get the owner to let you use it a few times, bend some metal and just generally get a feel for how it should be. After this, go home and set up the drawing board - you are going to be making a bunch of sketches now. The only way to try and avoid to make something that does not work first time, is to really plan it down to the smallest detail. Start by making a list of features that you want your machine to have.
Metal Saw
- How large pieces of sheet metal do you want to bend? And what is the desired maximum thickness of material? This will have an impact on the size of the machine, the heaviness of the materials needed, and also on the price of course.
- How easy should it be to set up and use? And how fast? What I mean is, will you be using it often enough that it should be ready to go at any time, or could you make do with something that needed a little assembly before each metal bending session?
- What can you actually build with the tools, space and money you have? Do you have access to welding equipment, or will you have to assemble your creation using only bolts? How will you make sure the clamping leaf, bending leaf and bed are smooth enough? Can you afford to buy a few bars of heavy steel and have them ground smooth in a machine shop, or will you have to think of something else?
As you can see, there is a lot to think about. How far you go, will depend on what you expect to get out of it, in terms of the quality of the parts you can make with your finished sheet metal brake, so if you need some even close to precision, make sure your machine is made to tight specs. I have to say, that the closer to professional quality you wan to get, the more it makes sense to just go out and buy one instead! So before taking on a challenge like this, you should probably first ask yourself what is more important to you - the result or the process?

Produces Smooth, Quiet Cuts with Laser-Cut Kerf
The Freud D0748F's clean-cutting design means that you can enjoy the comfort of smooth performance. The thin 0.102-inch kerf between the blade's 48 TCG (triple-chip grind) teeth is laser cut to provide ease of feed, so you have more control over the blade's position. This helps maximize both the accuracy of the cut and the efficiency of your work, so you enjoy a job well done and the ability to complete more tasks in less time.
An added bonus, the blade's laser-cut stabilizer vents reduce noise and vibration during operation, keeping your work environment more relaxed and your hands more in control. This feature also reduces friction to the blade, helping extend its cutting life.
Features Shock-Resistant Carbide for Long-Lasting Precision
So you can count on it over the long term, the Freud D0748F is designed for durability. The blade's hardy teeth are protected by Freud's exclusive shock-resistant TiCo Hi-Density Carbide formula, which helps fight wear and tear and maintains blade sharpness up to four times longer than standard carbide.
The blade owes its robust performance to its premium-grade steel, which is hardened to HRC 48 for an optimum level of durability. And protecting the blade is a Perma-Shield Non-Stick Coating, which provides resistance to heat and corrosion.
