Make Vinyl the Easy Way

Leave a comment

You may find the chemistry behind vinyl complicated, but it’s actually simple (see “Ode to Old Vinyl,”).  Yes, you can make your vinyl records with this easy step-by-step guide.

Step 1

You will need a source of PVC.  Many materials contain PVC, including credit cards and pipes.  If in doubt, find your parents’ old records and simply melt these down (make sure to remove the labels first; if not, it will result in an inferior quality record).

Step 2

Melt down you PVC.  This can be done over a kitchen stove.  Avoid breathing in the fumes as they are highly carcionogenic.

Step 3

Add pigment.  Black records may be obtained by added pencil lead (graphite) to the mixture; other colors can be obtained using food colorings.

Step 4

Pour your melted vinyl onto a flat plate and compress with any weights you happen to have lying around.

Step 5

Remove your disk and carve groves into it in a spinal pattern.

Step 6

Play your new record!

Rat Control

Leave a comment

Rats are one of the most difficult problems framers have to face the whole year round.

For traps, you can dig holes in different locations around the farm.  The holes should be 30 to 40 cms (14 to 18 inches) wide and 50 to 60 cms deep (23 to 28 inches).

Fill the bottom of each hole with water.

Rub the sides of the holes with a mixture of dry ground fish and coconut oil that provides an attractive odor around the hole.

The smell of the oil mixed with the fist attracts rats.

When rats try to eat the food, they will fall into the water at the bottom of the hole. They will be trapped in the hole until you get rid of them.  (PCARRD FARMNEWS, 1992)

Hollow Block

Materials:

Cement, sand, wooden molds, measuring can, trowel and water

Procedure:

1.  Measure the materials using the measuring can.

2.  Mix 4 parts sand with 4 parts cement thoroughly.

3.  Form a mound and make a circular hole in the middle of the mixture.

4.  Pour about ½ of a measure of water into the hole.  Allow the water to seep into the mixture.  Mix well.  Add more water if needed.  The mixture must not be too dry or too wet.

5.  Place the mold in an upright position on a level surface.  Put the mixture in the mold until half-full.  Pack the mold.  Scrape the surface.

6.  Invert the mold carefully and pull the mold upward.

7.  Sprinkle daily with water for a curing period of 28 days.

8.  Test for compression strength by successively loading heavy objects.  Record the total mass [kilograms] of the objects when the block cracks.  The will tell you how much your hollow blocks can hold. – Bato Balani

Charcoal from Corncobs

Leave a comment

Charcoal is being explored as one fuel source because it is relatively less expensive, cleaner, safer and more efficient than most current fuel sources.  Charcoal burns hotter and cleaner than wood.  Unlike coal, it does not release sulfur into the atmosphere.  It can also potentially reduce the number of deaths due to fumes from indoor cooking fires.

Charcoal can be produced from inexpensive and widely available refuse materials such as sugarcane, corncobs, or waste paper.  Corncob is an ideal material to use in the Philippines since it is widely available in farms and other agricultural areas.

 

Corncobs

Corncobs

What you need:

Corncobs

200-liter-capacity drum

Water sprinkler

 

Procedure:

1.  Fill the drum one-third of the way with corncobs.  Burn the corncobs until the smoke goes away.  Be careful not to put too much corncobs as they will not burn properly.

2.  Add more corncobs so that the drum is not two-thirds full.  Burn these corncobs until the smoke goes away.

3.  When the smoke has completely dissipated, empty the drum and spread the burnt corncobs.

4.  Sprinkle water on the burnt corncobs.

5.  Leave the corncobs under the sun until completely dried.

6.  Separate the ashes from the charcoal.

7.  Store the charcoal in a clean and dry place.

Use the charcoal for your daily needs or produce them in mass amounts as a source of livelihood.  In either case, you will help yourself and the environment.
