Davis left hand thread screw
 

Hi all,

I was cleaning up Davis rotary. I need to take the bobbin winder off the pillar. After increasing screwdriver sizes and asking for help to secure the base, I was stumped. Winder wobbled. hmm. On a whlm, I turned it clockwise. Yea. It unscrewed. Maybe you know this, but it as a surprise to me so thought I'd share.

How odd. Well, good to know!

Nice work. Probably made by National rather than Davis. My Davis made Davis Rotary screw loosens counter clockwise.
