Hi VAF I'm installing a stall warning vane in my 7A. When the vane itself was rolled and welded it is a little off center. I was able to buff a little off the vane to allow clearance from washer. My question is does the vane move quite freely with no resistance? at the moment there is resistance. ( I have used all the appropriate washers to this point) I could buff a little more off around the area where the bolt fastens it. Any input would be appreciated. Thanks in advance. Ken
