I’ve laid the bottom deck on top of a skirt to
verify the skirt is properly sized and even all
the way around.
Don’t add more tape than necessary. The
taped area of the skirt should not extend
much beyond the nozzle plates. Don’t
worry about measuring the size of the tape
at a microscopic level of precision.
I only drew the diagonal lines near the center of the skirt
as I didn’t want the lines across the entire skirt. There’s no
reason you can’t have corner to corner lines in your skirt;
they might even look neat if drawn in a variety of colors.
drawn on the
plastic and draw a larger, concentric octagon using the
opposite edge of the straight edge. That way, you don’t
have to measure 1-1/4 inches beyond the first octagon to
draw the second larger, concentric octagon.
But wait; don’t cut the skirt out just yet! You need to
draw a third and larger octagon around the two concentric
octagons you already drew on the plastic sheet. The largest
octagon is where you will cut out the skirt. Since you have
a straight edge handy, use it a second time to draw the
edges of the skirt. So again, lay the straight edge alongside
the second octagon and draw another, larger octagon.
Now you have three nested octagons that should look like
the image shown here.
Now you can cut out the skirt on the outermost
octagon. I used the Exacto knife and straight edge to make
a clean cut. A pair of sharp scissors will do the same.
dozens of experiments). If you try different amounts of
billow, please contact me to let me know how it went.
To make the border as uniform as possible, lay one side
of your straight edge up against the edge of the octagon
Attaching the Nozzle
to the Skirt
You’re not ready to affix the skirt to the bottom deck
yet; you must attach the nozzle to the skirt before
mounting it. Begin by removing the nozzle from the bottom
