Building MINI battery Op Box Fans...

[Bejon A. Boranian]

...The build begins-! 😎

Well sorta... Here's the progress thus far:

...getting there...

...need to decide on brand, features etc...

 

[Bejon A. Boranian]

...Turns out that it can be equipped with the following:

-Infinite Speed Module

-Onboard battery supply (9Volt)

Other features or Optional: (?)

-Tilt stand that is adjustable

-Lamp

...In the works:

Lakewood's "Banana" Blade...

Used primarily on BOX Fans,

 ..also used as a HV blade later on...for air circulators.

PICS:

Balance complete...

...Now, for a test:

...Can it be painted?

Results so far:

(First PIC is of actual full size 20" Lakewood blade)

...Second PIC shows my mini version with a fresh coat.

...Now to let it air dry.

...Finally, some time to resume building...

..I have had this design in mind,

now I can "Test" it via my basic PIC editing...

The "Penneys" Box fan

...Penneys badge development:

Using JB weld and aluminum foil,

Cool stuff! The AFCA has some talented guys! I can only aspire to! This is fun stuff! It it amazing what one can get with a little sugar and not poring vinegar on people!

...Been awhile, 

Here's a blade update:

Banana Blade, 2nd attempt.

Material used: refuse blade off some RV camper lamp thing I found.

Basically, I cut, sand and "mill" the plastic to my desired shape...

...Result:

 

[Bejon A. Boranian]

Tools used:

My (Broken) "xacto" knife blades, a DC motor, my master blade copy

and every ounce of energy I can get out of a 9volt battery.

Waste not, want not... 

...These materials made me my own DIY mini lathe.

...Here's more comparison PICS:

This is currently my newest, smallest, most detailed banana blade.

 

[Bejon A. Boranian]

Shown running:

(Quick video):

The 9 volt used is at about 80% power.

At 100% power the blade upgrades itself from box type to circulator.

The blade can be used for both purposes.

 

[Bejon A. Boranian]

...Now,

Lakewood put a vent pattern on their blade...

Sometimes, one will be open, all closed, or more rarely FULLY open vents.

I opted for the latter:

Banana Blade,

Now vented:

Had to be balanced... Carefully.

4-way brace inside hub x 10 vents = Balance not yet true

Solution:

shave/ cut at precise points, slight enlargement of key vents,

mostly near the 4 support braces.

Result:

Test 1:

"As a Box fan blade"

Note:

9 volt battery used only at 70% power

 

[Bejon A. Boranian]

Test 2:

"As a circulator blade"

(9 volt at 70% ...)

Significant power difference due to higher speed motor used.

Drawback:

Motor is a "gas hog" and will eat the battery at a faster rate.

Perhaps the price of performance??

Full size Lakewood circulators do gobble up more energy...
