Introduction: Rocking Hammock Stand

This is an Instructable on how to make a rocking hammock stand to recreate the sensation of floating on a long-tail boat in the Pacific. You will need

2 - 20' long, 2" x 1.5" steel tube with a wall thickness of at least .12"

1 - 3' x 4' sheet of steel .06" thick

A tube rolling machine to bend the tube

A shear to cut the sheet metal

A punch to cut holes in the sheet metal

A MiG welding machine to weld the tubes and sheet metal

A hammock (with rope)

Step 1: Bending the Tube

Use a tube roller to bend the 2 tubes until the ends are 14' apart.

Step 2: Cutting & Welding the Tube

Next place the center of the arcs on the ground, about 6' apart from each other and lean them towards each other at a 50 degree angle. At the point where the ends cross making an X shape, mark the vertical center line on both pieces where they cross, then cut both tubes with a handsaw creating an upside down V.

Once cut, fixture the two tubes next to each other with some 2x4s. Then MiG weld the tips of the tubes together.

Step 3: Cut & Weld the End Panel

Clamp one corner of the sheet steel onto the corner where the tubes meet, with one edge following the outside edge of the tube steel, then clamp 2' down each tube. Trace along the outside edge of the opposite tube, then draw a straight line from one clamp to the other. This forms a triangle between the top corner and the 2 clamps, the outline of the end panel. (Repeat for the opposite side)

After the panel is cut, punch two holes 6" directly below the top and 1" out from the center line. Fix the panel to the tubes using clamps and zip ties, tack along each corner, remove clamps and zip ties, then weld the panel to the tubes.

Step 4: Set Up Hammock and Swing Away!

Tie your hammock through the 2 holes on each side, hop in and start swinging on 2 axes!

Great design, skipped the triangular plates instead using a piece welded to the inside to hang the hammock from.

I bet, with a bit more structural support, this could be achieved with pvc pipe. Great hammock stand!

"a tube rolling machine"....I'm thinking that's like a lot of these that start with CNC plasma cutter, laser wood cutter, 3X4 foot printer for layout...... But I am now thinking maybe steam bent laminated wood with cross braces! Great idea!

A see what you've done...First I thought "Tube rolling machine" ...not for me thank you ....but now you've gone and mentioned bent wood and I'm thinking well okay I can do that...which just increases my projects to do list..hehehe

I was thinking large diameter bamboo. Apparently you can bend it by heating with a blowtorch. http://www.architerials.com/2011/12/qa-special-how-to-bend-bamboo/

Can you make a giant hamster wheel but for people?That would be so much better than a treadmill.

That's not a giant hamster wheel. Is there an article that goes along with that? I'd be interested to read it to see what that is all about though. The rocking hammock is cool.

Dude, you gotta add a video of it in use! So cool.

Very cool!

Do you think the rockers will tend to splay out a bit over time with use, or is the frame super rigid as is?

The weight of the person in the hammock bends the frame inwards slightly. It hasn't been a problem structurally, but because there is some flex, the rocking motion can be a bit bouncy. To remove the flex, you could weld cross beams chords across the bottom or use a thicker wall thickness.
