It's actually the 3rd version, and
although it fits ok, it's not MACHINE perfect... yet.

Here is print that breaks it up into 4
pages. Somebody pointed out they couldn't get the above three images to
fit on one sheet, so I made this one:
RADIATOR SHROUD 1

Quick and dirty walkthrough:
- Choose a material: I chose a galvanized steel panel that felt like
20 gauge or thinner from my local home improvement store. (Lowes or Home
Depot) I know it's not the best material, but I'm making a prototype
after all and the real deal is going to be 0.05" aluminum.
- Print my handy template onto 3 sheets of 8.5x11 paper. Tape them
onto your steel panel, FRP, or fiberglass. Make sure you check the bar
scale I put on the first sheet that it matches a ruler. This is a little
handy trick of checking the correct scale of the plot.
- Drill the holes. You actually don't have to cut a SQUARE, I just
made a circle there and it fit fine. I used a hole punch and die.
My set cost around $26 from Harbor Freight. It's basically an industrial
hole puncher that you use a hammer to punch a steel cylinder through a hole
making a HOLE PUNCH in your sheet metal. It's a little slow using it,
but the holes are great quality and better than if I used a drill. If
you use a hand drill I recommend Milwaukee drill bits.
- Cut the pattern out. If you're using a jigsaw/sabresaw, wear eye
protection. You can also use a nibbler, or if you've got a metal shop,
then use a metal band saw. If you're using tin snips (LIKE ME) then make
sure you get a pair of GREEN and RED handle snips. Tin snips make a
decently clean cut very fast and it's the cheapest route to go with if you
have no tools.
Use a file to sand the sharp edges down. You may also use a dremel
if you have to grind down material to make the right radius's and curves.
Use a metal primer and automotive paint. If you want you can use
engine paint that may be more durable in the long run.
Installation. TWO screws, just slide it in. Optional:
Depending on the material you used, you might want to secure the front of the
shroud to the grille with some double sided foam tape, or if you want to make
your own method of fastening.
|Green snips cut clockwise.

|TIP: Wiss is a good brand and I've had a pair that's like 8 years old
and still works great. You can buy some cheap aviation tin snips for
$8-10 if you go with chinese steel from Harbor Freight or an import brand
like "workforce". I'm not sure if these will cut as well and last as long as
