[Rhodes22-list] Motor lift “bearings”?

Mon Jun 29 13:19:49 EDT 2020

Thanks all. I think the bearings went out over the past couple of seasons
as the movement of the carriage has been getting worse. Here’s also been a
hairline crack in the mount/carriage itself that’s very worrisome...I check
the “leash” on the motor a few times a season!  So it might be best to
upgrade the mount to the linear bearing design even if that requires a few
extra parts. Still waiting to hear back from Stan.
