While repairing a handclutch on a CA in the shop I thought I would post a quick pic. You can tell this is an Oklahoma tractor by the mud dauber nests! For those not acclimated to these lovely little black wasps, they will plug any hole the size of a pencil lead. I have to keep all my air tools on a peg board with a nail in the air nipple. Otherwise I have to disassemble them and clean everytime I want to use them. Then in the spring we get wood bees. They drill 1/2″ holes in wood faster than a DeWalt. I plan to breed a wasp that will kill the wood bees and plug the holes with mud.
