Thanks Aaron.
Edited my last post. Used a dial caliper instead of my eyeballs.
I wasn't expecting it to be 7/16" like my Remeys..................................................................
Are you matching a loop of 7/16" chain that you want to run? Otherwise, you'd be better off going with 3/8 or .404. There are several 7/16" spur drums on feebay now. I found a bunch doing a "Homelite 7/16" sprocket" search.
