Most welcome C-Bag! Pic 1, 2, & 3 looks to me like some kind ring is around the neck of the drum. Assumed it was an O-Ring for the channeled rollers to ride on. Would imagine it could be a steel/tube ring though to stiffen the neck of it for riding on your roller support and the weight of the dirt. :confused:
Thanks for the detail on the coupling, pretty sharp thinking and repurposing! I get it now! I've tried to avoid fruit and nut trees because of a summer picking walnuts as a teen...for someone 6'6" it was a long summer...:rolleyes: However I never minded getting apples for my Gma to make her unbelievable apple sauce. :rocker:
