Fan
with Shroud
I
made the shroud out of thin cardboard that I taped with thin aluminum
duct tape, the real stuff. I used 4 sections, each sealed at the ends.
Quite a bit of air drop having to pull through the radiator only, it may
be too air tight. My hat might be on too tight, who knows.

[If
you don't have a roll of aluminum tape, maybe get some, it's probably
the most handiest stuff around, next to Hot Glue and Dremels, of
course. Pricey, but worth it. I just slice pieces up as I need it. It
forms and sticks very nicely, and using layers makes it quite strong.]

pump.

view of fan and shroud. I do have sort of a Plan B if this fan doesn't
get it... a couple of 120mm's ought to do it, even one Hi Flow.
Sunday, April 21st. It's beautiful outside my door, warm sun shining brightly through the wispy chemtrails gently spreading their rainbow veins across the sky, connecting with the other trails that crisscross the sky like a chemcross pie crust-what a perfect day for Squaring, Compassing, Dremeling, Sawing, and Filing ....indoors.

After
measuring the fan/rad unit inside the case, I transferred the measurements
to the case cover. Here's the rectangle for the radiator side.
The
Circle.
As
I cut along, I would tape up the bottom and top along the slices to steady
the metal as I Dremelled it, and when the cut was completed, the piece
didn't fall out leaving a burr.

Tools,
ready for action. Notice the neat hacksaw handle/holder? Inside cuts are
no problem with it. It also helps to dab a bit of light oil along the
cut path when using the hacksaw to speed up cutting. It was a good day
all in all, only went through 3 cutoff wheels and no bandaids. After the
cuts, I filed the burrs smooth. Don't forget the safety glasses, you know
how these little cutoff wheels like to disintegrate. </osha>
The
radiator side cut. There is a strip of window screen retainer that I slit
for a trial edge moulding at the top. It's way too small, grey, and ugly,
so it looks like a trip to the hardware or automotive store. Black rubber
hose, slit, might work, whatever comes first....

The
fan side cut. This cut took about 20 minutes, breaks included, and for
some reason, it came out exact ~ sometimes miracles do occur. This
205mm hole sorta makes a 120mm hole look anemic. I find that if you just
take your time, make a few passes instead of trying to maul the cutoff
wheel around, it comes out a lot nicer, and rounder.
Rear,
top angle shot. Next, to find some sort of edge moulding to take up some
of the fan-to-cover space. I suppose I could salvage some from the old
van parked outside, but I don't think my ol' Pop would appreciate it,
even if it doesn't run. heh. One man's junk is another's treasure, and
besides, it's paid for.
