Hello, dear readers and DIY!
Recently become a popular topic of creating different designs based on a special way stretched strands, ropes, cables and chains. This method gave the name Tensegrity (tensegrity).
At first glance it seems that this design can not keep the right position, not to withstand the load.
In this article, the author of the YouTube channel “izzy swan”, will tell You about two options for the fabrication of racks for table or chair based on this principle.
Such racks are very easy to manufacture, despite the author used CNC milling machine. It will be enough an electric jigsaw and a router.
— Sheet plywood
— Nylon rope
— Screws for wood, Titebond glue, sandpaper.
The tools used by the author.
— Nailer electric
— Manual mill
— Milling machine
— CNC milling machine
— A set of cutters for wood
— Drill press drum sander attachment
— Digital caliper, square, ruler, pencil, scissors, knife.
The process of making.
So, the details of the table will be made from a sheet of birch plywood. This is a plywood of high quality.
All the details the author fabricates using CNC milling machine.
When you are cutting on the machine, so the details are not popped during processing at the lower sides of the slits were provided jumper.
Then the workpiece is flipped, and the remaining jumpers are removed hand router.
Next on the milling machine is processing the edges of the parts with the radius of the cutter with the thrust bearing.
The result was six that such arcuate parts.
Now the master picks up a nylon rope of sufficient strength.
He measures its width to determine the diameter of the holes that must be drilled. Thus, the thickness of the nylon rope is ¼ inch.
At both ends of each C-shaped parts are drilled a through hole for ¼ inch, but first made their markings with a pencil.
Then made two lateral holes for fixing screws that are clamping the rope inside of the holes.
Setting on the drill press drum sander attachment, the author handles her all the surface details.
Round table top and base table master produced from a pre-glued wooden shield.
When you cut the countertop using a router and circular nozzlesin the center of the workpiece remains in the hole.
About manufacture and work with a circular attachment for a router was explained in detail in a recent article.
Into this hole is inserted the drill, and it is worn on the first segment of the rack.
On the lower side of the base in the hole is passed a rope. Between the edges of the first section of the rope is inserted through the hole in the next.
In the same way, alternating sections, the author puts the rope on.
The rope is threaded through all the sections. Now came the most interesting moment.
To the whole structure retains the vertical position, the rope you need to pull.
In this business helps a partner. While he holds the rope taut, the author twists the screws into the holes, locking the rope in segments.
Here’s the front of the five sections worked.
But John doesn’t stop there: it creates a small chair on the same principle.
The workpieces after cutting on the CNC again.
In this embodiment, it was decided to use two V-shaped element for reception. In the Central part also drilled a hole for the rope.
Also prepare the cross holes for the screws.
The first part is attached to the chair base, with the sides glued corners to increase the strength of the connection.
On the reverse side of the base they are driven nails with the help of nailer.
The second part should be glued to the seat in the same way, only preliminary it is necessary to pass through the resulting “arch”.
And again the joints stronger nails.
When all the elements of the table are ready and assembled, just have to connect the upper and lower part with rope.
The rope passed through a hole in the base and passes through both spacers.
To the underside of the table top is attached to the block with the hole. This block will be fixed end of the rope.
From the bottom of the Foundation hole was pre-extended, so that it will fit the knot.
And again comes to the aid of a partner who stretches the rope, stepping on the base.
While one end of the rope is kept taut to the maximum, you should retighten the screws. Special attention should be paid to the latter, the upper screw. It should capture the end of the rope.
Everything is ready, the excess cord can be cut.
To test the chair to the seat, fit a wooden beam weighing about 36 kg.
The author decided to add a load in the form of a bag of cement, but one of the mounts broke.
Everything was very simple. The end of the rope was properly secured in the unit under the sink, it fell apart, and jumped.
This slightly reduced the stability of the seat, and it is slightly tilted in different directions.
To resolve this problem simply. After fixing the rope in the block should fill the hole with epoxy glue.
These are the options stands out. It remains only to clean the product, and covered with a protective lacquer.
I thank the author for a simple and unusual method of making racks for the chairs or tables.
All good mood, sound health, and interesting ideas!
