I found this strainer/ sifter at Wal Mart. It is out of a flour sifter, looks like a large fruit can with a crank handle. $4.59. Fits perfectly on the P-120. Just pop out the handle and the strainer comes right out.
I used a Dremel to cut out the center hole for the starter, then soldered the edges. It is held in place with an automotive O-ring.
