An iconic reel design is the Hardy Perfect. I have never had one in hand to photograph but I did borrow a Hardy Bougle from a friend, and it is the same thing except that the frame is raised pillar instead of round.
Another notable feature in this design is the ball thrust bearing. I have never really understood the reason for this bearing; seems that if you wanted a ball bearing for axial forces, you would want them for radial forces also. I have never used ball bearings, too many tiny moving parts.
What is the real advantage of this design? I don’t know, but I do observe that one face of the spool is accessible for “palming”, to create additional drag.
Instead of the ball thrust bearing, I have a plain bearing of Delrin (the ratchet face) running on bronze.
If the reel is palmed, then axial thrust is in the direction that the thrust assembly does not support. On a Hardy reel, this load is taken by a small area of spool aluminum running on the end of the frame bushing. Here, the bronze spool insert runs against the bushing.
This reel is cosmetically defective due to failure of my anodizing process. There are stains embedded in the oxide layer. I think that the aluminum alloy may not be 6061, which is a good anodizer. But it seems quite unlikely that something else would have been supplied.
Update 18 Aug 2020: I believe that I have found the cause of the cosmetic defect in the anodizing. By changing the rack (the anode support) from titanium to aluminum, I have been able to eliminate this problem. I don’t understand the cause, but I do have the cure.
