  • want to build my own square tubing bender Need ideals!

    Hi all I am New here and and might ask some dumb questions but here it goes

    Was hoping I could get some ideals on building a square tubing bender and where I can get dies for bending square tubing ?

    Thanks so kindly!

    I made my own square tubing die (pictures in Post#27) because most of the commercially available square dies had that "Crush Tab" that collapses the inside wall when it bends. I wanted a completely smooth bend. It was also made for free out of scrap steel as opposed to several hundred $$ for a JD2 or Pro-Tools die.

    Shop outfitters has a nice machine and price not bad either. It works good as i have one.

    Dude...post #27 is doing exactly that

    Good job

    NYS3, simple and effective and bending 6061 on top of it. I'll be making one soon for my smaller radius requirements.

    Square elbow

    Another option: go to http://www.quickfab.ca/index.html for pre-fabed elbows.

    Here are some pictures of the homemade square tubing bender I built from some scrap 1/4" steel. I used this for bending some 6061-T6 square aluminum tube (1"x1"x0.125") up to 90degrees without any kinks or bulges. I was anticipating filling the tube with sand but it wasn't necessary. It's important that the dies comes apart so you can get your tube out once it's bent. The die uses a standard HF pipe bender machine.

    Material options

    This die will work for sharp bends that wont matter for the application that I will be using it for
    Will try the sand trick to see how that works wife had to have this place so I've been cursed with 2 ac. Of sand and oaks
    The 1-1/4" tubing dimpled on both sides not sure if the sand trick will help as it is a sharp bend with the small die, at any rate I got the general ideal of how to make some die's just need to figure out size of die to use.

    As for aluminum will it deform like the steel using this method of bending ??
    And was thinking about a material that a neighbor who moved here from Alaska
    Was telling me about that he used for building decks it's like a fiber plastic type material
    Which will weather better than wood with out needing to be sealed every year.
    Thinking of using it on picnic tables for the top and benches. I seen it at one of the local lumber yards the other day but is kind of price. But my first project is going to be a picnic table just to start with something basic and easy but try to implement back rest to the bench seats and end benches.

You can also get Okoume BS1088 Marine Plywood and it is rated for marine use + comes in thin ply that bends well for laminating.
    Smart stuff! There are some BIG possibilities using square AL and plywood- neat. Look forward to some progress and finished pics.

    Laminate thin (1/8"" plywood pieces and introduce some curvature to make it comfy. Treat it with Zar.

    This shape is simple and MAYBE even comfortable. I am a big fan of plywood and love to integrate bare aluminum, welds and all, with wood- looks cool.

    Here's the product I used on the front of my house, South side, on the paint stripped windows and door:

    For the areas where people sit metal can be hot/cold wood is a good material for seating but will require yearly maintenance. If you use the more weather resistant woods be cautious as they are not good to breathe the dust "no dust is these are worse" , teak, redwood, and ipe are some of the best. Ipe can be very toxic to the person machining it, in Hawaii I had seen this whole window shop get shut down and the employees all hospitalized due to exposure to the dust. I had been making gates for the same estate they were making the windows for and lucky for me we had an outdoor machine shop. I also noticed the wood made my skin slightly itchy, so I suited up in a painters suit and wore a respirator and was speared the suffering of the window guys. Inflamed lungs, bleeding festering welts ect. I don't know what OSHA did to the employer either.

    Other options to consider concrete, cushions on steal, some type of webbing.

    Don't forget to consider drainage for outdoor furniture.

    Almost forgot bamboo would also be a great option thermal and weather resistant, you could find some of the composite bamboo materials and stay away from the jungle bar look too.

    i would consider using aluminum first, then SS as a second option.
    1" square aluminum is light and strong. SS would also be good and strong, but not as light. and high $
    they both have the added advantage of being easily finished with or without paint. the SS would be easier to weld if you are a bit rusty on your TIG skills.
    whatever you chose to use i would burn up a bit of scrap before embarking on the project, even if it means buying a few extra feet just to practice on.
    FWIW; i found 1" aluminum easy to weld on and very strong when i made my welding cart.

    Thank you! to you all

    Just wanted to say Thank you to all of you!

    All the links you guys have provided have been very useful
    What I want to build is outdoor furniture using square tubing frame and a square tubing bender
    Just seems to be the only way to get nice bends with out a lot of miter cuts and extra unnecessary welding.

    I have some really great design ideals for this project and hope that I can market the out door furniture in the near future.

    Once I have one of these projects completed I will post photos and you can let me know what you think.

    Also I would be curious as to your comments or sugestions of what type of materials you think should be considered to be used for the bench seats and or table tops
    i.e. Wood or metal.

    Kind Regards
