Mag-brake tuning.
After 4 years in salt service, my oldest Super Duty G showed its first rust sign - only in the magnets (everything else all through the reel looks pristine).
This is filliform corrosion - sideways under a coating - a mechanism for a little bit of salt from the air, combined with condensation, to concentrate in place - and you can't remove it, without removing the coating.
(The silverplate coating is there to keep the magnets from rusting, etc.)
I did clean and rebuild the whole brake plate, and everything inside was pristine
on that brake rebuild, getting the knob and cam plate in phase - 6th time's a charm...
I ordered Momo N52 magnets through Ali Express (AMO store). While their piece-price on these looks dirt cheap, they hit you with a big shipping charge.
I ordered 8, and they came prepackaged as 10 - the $17 total price was still fair.
BTW, every old magnet that came out showed incipient attack on the bottom.
The Momo N52 magnets are gold-plated - will be interesting to see how this fares compared to the coating on the stock magnets.
These magnets are powerful. In my 1/4-oz niche on the old magnets, I had the mag set a notch above 50% for total-reliable casting, and great cast distance.
Test casting with the 8 new magnets, incipient backlash was only about 20% mag adjustment, and the next two notches were excessive step changes on the cam - too much mag.
So I took two magnets out.
Trying again, didn't cast or adjust enough to find incipient backlash, but was getting 120' reliable cast at a little over 40%, and several notches in that range felt better graduated - that is, narrow changes in mag over several notches.
Ready to go fishing, and since I'm here, my oldest Super Duty G.
The red tension knob is Avail and the thumb clutch is AMO - neither color part was spendy.
