Playing with Pond Fountain Feature Elements

To operate Pond Fountain Features control devices need to be purchased or made. Purchase the control devices can be expensive, so I started playing with some PVC connectors to construct some useful devices.

The first device I wanted to create is a "Quick Exhaust Value" (QEV), it can be used to trigger a large shot of water (see previous blogs).  A QEV is really just two check values of two different sizes with the check elements connected between the two. The check element can be just a single (double ended) device, like a ball or shuttle piston.

My First Attempt - FAIL

An Attempted QEV - FAIL

Cut-a-way of the Failed QEV

I think this would have worked if the Ball was less squishy and it fit tighter within it guide tube.

My Third Attempt - SUCCESS

Another QEV that worked

This value uses a hard shuttle that moves to activate the to ports, it leaks a little but that can be fixed with some rubber on the face of the shuttle.


Then I attempted a low head Check Value for automatic refill of the water feature. The Ball that was used floats in water, therefore it must be used with a particular end up, but this provide very little over head for trickle refill of the fountain.

Other devices were also made.

The use of these devices will be seen in future Pond Fountain blogs.

Air Tank for WaterCannon

I am playing with the idea of a Local Air Tank for the WaterCannon (see previous post). I am trying to use of 2 litter Soda bottle as the local tank. I think 8 bottle will be necessary for my large WaterCannon, tests tell.

An adapter for the Soda bottles will be needed.

An Adapter will be made with matching bottle threads

On the lathe, matching threads will be cut into the standard PVC adapter.

Ready for Assembly

An O-ring will be used on the bottle's standard thread flange.

WaterCannon - Full Pressure Test - Success

With better mechanical air and water connections, the Full High Pressure test was a Success. The air pressure was 120 psi.  Data from measured and observations compute the water went 58 feet up, that is; 27 degree to top, and 110 foot baseline.

-

WaterCannon Tests - FAIL

This first High Pressure test at 120 psi FAILED. A better mechanical connection is needed at the air input port.

Water Cannon Tests - Take 3

This is the third test of the construction of a New Water Cannon, which will placed in the Duck Pond, . . . someday.

With the current configuration, the best guess is: it shoots water up to about 50'.

Second Test

The screaming noise is chatter within the Air Valve, that will be eliminated with adjustments.

Eldon's Adirondack Chair

This is an Adirondack Cedar Chair built for the Pond Area, it is large comfortable and adjustable with three angle positions of the back. Most of the construction is made from inexpensive 5' x 1/2' Cedar Wood Fence Slats, with two additional Cedar 2x4's use for lags and  the back frame.

The cost, about:
  2 - Cedar 2x4's, at $9.00 each
20 - 5'  1x6" Cedar Fence Slats, at $1.55 each
  1 - Fiberglas Fence Rod - for the Hinge and Pins, at $2.00
       Outdoor Deck Screws and Staples, as needed, Approximate $5.00
Raw Materials - About - $55.00

Eldon's Adirondack Cedar Chair

The design has not yet been documented, but Jenny wants four more to be built, and therefore diagrams and cut lists will be made for the production process.

Here is the Chair at the Pond

At the Pond

Cyanoacrylate Adhesive (CA) was used to "paint" the end of each leg to help preserve the Cedar from rot. CA was also used to attach "T" stiffeners under each of the seat slats, and CA was used to attach the Arm Rest Tops to the outside rails. Outdoor Wood Screws and Staple where use for the construction.

The rough Cedar was only sanded where it would be in contact with a user.
