One of my amemometer cups broke off during the hail storm at Spearfish. The only replacement I found was a new Girard anemometer for $142+shipping. I ordered a wireless wind sensor replacement cups from La Crosse Technology outlet--$9.95+$3.40 shipping. I ordered on the 8th, first class mail and received it on the 11th. I pried off the broken cups using two screwdrivers. The shaft on the anemometer is .160. I used a #22 drill (.157") to increase the center hole size, which allowed for a press fit which is how the original one fit. The fix passed the first test of bringing in the awning when the cups were spun.
