Pacific Ring Weave

Nice progress Spark!

I did get a bunch of tires and almost got four quad centers woven together. All the tires weren’t exactly the same size though, so didn’t quite work.

Thank you for the nice words.

Congratulations on your work! Yes, I ran into the same problem.
The tires have to be the same size, or the belts have to be cut.
Cutting the belts is not easy with the steel belt, embedded in the rubber.
The width of the belts has to correspond to the length of the belts.
A large tire gives a longer belt, but the width of the belt is bigger too. This messes up the
woven matrix.
The width of the biggest belt has to be the fourth of the length of the smallest belt. IMHO

I am trying to find a way to use the entire tire without adding anything to it.

I have arrived to point where the belts have to be cut, or the tires have to be sorted.
I choose to cut the belts.

I have posted a few pictures on reddit too:

Some posts are for humor. I hope you can sort them out.

I am working on a full scale prototype with half cut belts to produce a mooring line.
I am planning to incorporate the side walls into the structure.

The full scale prototype would make it possible to make measurements of length and
number of tires. This would make it possible to estimate the number of tires necessary
to built a certain length of line. It would be also possible to estimate the amount of work
necessary to produce a certain length. Not to mention the estimation of the recycling fee
to pick up for the tires.

Good luck and best regards;

I hope to read more of your posts.

An attempt to demonstrate, using s sub-scale prototye, how I am planning to incorporate side walls of tires into the woven tire structure:

A bit of data and calculations:

specific gravity of tires: 1.300 kg/dm3

specific gravity of seawater: 1.020 kg/dm3

Tires weight in air 100 kg get buoyant force of 78.4 kg.

(OK, would be better with force in Newtons)

Tires weight in air 100 kg, weight immersed in seawater 21.6 kg (1/5).

One half belt (cut) weights 5.5 lb = 2.5 kg.

All numbers are approximations, but close.

@spark | have you got some kind of feeback on the topic yet ( investor interest, cooperation requests, partnership suggestions )


#176

Nothing, that led to any results yet.
May be others are building something.


#177

length: 8.5 ft = 2.5 meters

number of half cut rings = 10

It takes 5 tires to make 10 half cut rings.

0.5 meters / tire, 1.7 ft / tire

APPROXIMATELY.

All is quiet on the western front. Ocean front properties are expensive in Southern-California.
I do not have enough money to buy one. Moving is expensive too.
Living expenses seem to be relative to earning potentials. I can move to a less expensive
area, but that gets me to lower wages. Or, may be , it is the other way:. higher possibility
of earing: costs more. Either way it is the same difference.

EFFECTS OF WASTE TIRES, WASTE TIRE FACILITIES, AND WASTE TIRE PROJECTS ON THE ENVIRONMENT

CALIFORNIA INTEGRATED WASTE MANAGEMENT BOARD
(California, USA)
.
.

In order to prevent waste rubber and in particular discarded automobile tires from damaging the environment,
it is highly desirable to recycle this material.
.
.

Stockpiling whole tires creates two significant hazards: mosquitoes and fires.
.
.

A study of the leaching of tire rubber from waste piles was published in 1992 by the
U.S. Department of Commerce, National Technical Information Service.
.
.

The test results showed that the concentrations of hazardous constituents detected in the
samples did not exceed the concentration values necessary to be defined as hazardous waste.
.
.
There has been a long term study conducted on tires immersed in sea water.
The study concluded that after 42 years tires constructed of polyisoprene and immersed at a
depth of 80 feet showed very little degradation. Analytical tests on the tires identified
that the tire rubber absorbed enough water to equal 5% of its mass. Concentrations of
rubber, carbon black, sulfur, zinc oxide, mercaptobenzothiazole, and stearic acid were
within ±10% of those that would be found in the original tire composition.
