Materials:

1. Obal (⌀ 10cm) x2 ⋍ 6€ each
2. Synthetic Fur (⋍1m x 50cm)

STEP 1 | SUSPENSION

• Take out the inner part of the Superlux suspension HM30
• Cut it in the middle with the cutter (Blade Knife)
• Put each part of the suspension in one of the hole of the Oball

STEP 2  | SUGRU (or silicone with cornstarch)

• Apply the Sugru (or the silicone mix) between the suspension and the oball, in order to glue both elements. One pack per ball is enough.

• Cut the figures with scissors

STEP 4  | SEWING MACHINE

• Saw the pieces of synthetic fur with a sewing machine
• Put an elastic cord on the edge and a plastic cord lock at the end of it

STEP 5  | MOUNTING ON MICROPHONE

• After 24h mount the windscreen on your microphone
• Put the synthetic fur on it
• Go to record in the wind!

VERSION USING NYLON SOCK
An extra step to reduce further the wind noise (shared by Luc Bélanger)

• Get a pair of women over the knee nylon socks, the translucent type.
• Before modifying the O’ball (between steps 1 and 2), tie a knot in one of the socks above the ankle part.
• Insert the ball until you reach this knot and pull the sock tissue until it is tight. Do not pull too hard, the nylon must give easily to pressure.
• Then grab the sock at the end of the ball and while pulling on the sock, to maintain tightness, make one 1/2 complete turn and turn the sock over the ball again.
• Pull again until it is tight and when you arrive at the previously mentioned knot, get everything tight and in place with a small zip tie. 
• DO NOT CUT the remaining of the sock yet.
• Now add some glue between the two layers of nylon here and there. You can try with plastic model cement or transparent nail varnish (sometimes it works, sometimes it doesn’t)
• It is important to glue the section of the knot and the whole thing around the opening… let dry a few hours and then cut the opening with a X-Acto, preferably with #11 new blades. Now you can proceed with the rest of the instructions.
