Diagram ExplinationEdit

  • 4 Copper Tubes with flared ends (at the rear) for Air Intake.
  • I Copper tube with flared end at the rear and installed center to the Air Intake tubes for warm air exhaust.
  • Inside component stabilizers made of .5" thick wood and appropriate size centered holes to retain the inner components
  • The Trigger mechanism for this design is a Nerf Handgun adapted to hold the switch and battery pack


Note: Depending on what particular components are available (such as the fan for example) some structural adaptations may have to be made, such as using 3" PVC or PVC adapters to accommodate your situation. An example that I ran across was when I bought the fan I am using. The frame that houses the fan is 1-9/16" in both directions, but exceeds the 2" O.D. that I need. So I will have to sand down the corners and round off the outside frame to get it to fit. Some of this is tedious.

Recommended Tools (to make it easier)Edit

CUTTING:

  1. Hack Saw
  2. Drill w 3iS" chuck
  3. Hole Saws (2", 1-112", 112")
  4. Drill Spade Bit, 5/16"
  5. Drill Bit, 1/8"
  6. Dremmel Type Tool w/cutting wheel

BENDING:

  1. Tubing Cutter
  2. Flaring Tool Kit
  3. Tubing Bender

ELECTRICAL:

  1. Small Needle Nose Piers
  2. Soldering Iron with small tip
  3. Small coil of Solder

MISCELLANEOUS:

  1. PVC Cement (small can)
  2. Rubber Cement (small can)


Before you go cutting, etc., taking an inventory of the parts that you have and their outside dimension or diameter (depending if their circular or not).

I had a difficult time acquiring my internal fan, but got lucky at Radio Shack at $15.00. Yes, I know, quite expensive for what I wanted to get but locating (even on line) a low DC voltage 2" cooling fan like you use in a computer is not easy, because most of the computer cooling fans are more than 2" and are 12VDC. The one I got will operate on a 9V battery.

You also need to figure out where you want to locate your battery (ies) and your switch. This determines how much wire (18-22 AWG) you need.

The Dremmel Type Tool and cutting wheel is only if you are going to adapt a Nerf gun as your Trigger Mechanism/Switch. Otherwise I see no use for it.
