Hobbyist bender for thick, but narrow metal?

Need some advice.

I'm in a condo with very limited space. Can't throw in a huge, industrial bender (don't need one, either).

I have an ongoing need to make various metal brackets for my truck. The thickest, most heavy-duty stuff I've needed so far was bending a 3.5"-wide piece of guage 10, 304 stainless steel to a 90-degree angle.

The majority of the work involves thinner, narrower, softer metals. Things like 1/8"-thick aluminum in 1" or 2" widths, or steel in the same dimensions.

Is there a tool out there that will allow me to do this at home?

If you a press or room for a press, you might consider a press brake that fits into one or a bench-style press brake. Something like these:





Or if you are bending close enough to an edge where you don't need the material to feed through (or if it isn't too hard to bend and can hang "outside" of the vise), you might try a vise brake like this.

Thanks, Clint.

Could you give me a make/model number for the first tool? Or anything I can plug in to Google to do some research. // edit - looks like "Press Break" turns up those styles of machines. They're a bit too large I'm afraid...

I actually already have a 6" vise brake, identical to your second photo. Unfortunately I've found that it doesn't work too well. On numerous attempts to bend 1/8"-thick, 2" wide steel, I reached points where I was bending the vise's handle instead of the metal. I was also using a 3"-long DOM-tubing pipe on the vise handle for additional leverage.

What about something like these options?

1. https://www.kakaindustrial.ca/produc...shears-machine
2. https://www.kakaindustrial.ca/produc...shear-and-roll

The specs for both state that they can only bend metal up to 0.04" thick, whereas I'm aiming for 0.125". Then again, their specs are likely for material that is the full 8" width, and I'd be working with 2" width max. Would these tools be able to bend thicker material if it's at smaller widths?

I searched for "benchtop press brake" and that one came up. It is carried by Trick Tools. The price seems a little high for what it is. You could probably find other versions out there or make your own.

I like that kind of bender too. They make version of that with replaceable tools so you can do scrolls and other decorative work.

Thanks for the feedback.

That KAKA UB-100 is appealing. And for the first time ever, it's something that is actually cheaper in Canada than on Amazon US.

The specs describe it as:

Quote:
HIGH CAPACITY OF HOT BENDING AND COLD BENDING. In term of hot bending, it can bend flat steel 3.93x0.59", round steel 0.86", square steel 0.86x0.86, angel steel 3.93x0.47. In lieu of cold bending, it can bend flat steel 3.93x0.2, round steel 0.71, square steel 0.63x0.63 and angel steel 2.36x0.31"
How does bending stainless steel compare to bending mild steel? Do you think this tool would be able to bend a 1" wide, 10gauge piece of 304 stainless steel to a 90-degree angle?

If you like that machine, be sure to look at the other variants offered by manufacturers. Sometimes tooling is cheaper for one or another or the capacity or capabilities vary. I think that is often referred to as an "ornamental bender", "universal bender", "scroll bender" or "flat bar bender". I don't personally own one and only have seen them in friend's shops. Maybe someone else will chime in with more experience.

Stainless is generally more difficult to bend than mild steel of the same dimensions.

Here are some others you might want to look at:

Look up compact bender. I have one and bend all types of stuff with it. You can do 90 degree bends or bends with different radius. I think mine came with 6 dies. I paid 99.00 and made a cheep stand.

I also made a larger attachment where I can bend 2.25 cap rail for handrail.

I think you should consider the Swag Press Brakes and an economy bottle jack press.
