Jureal has raised the bar on magging, well done. For additional input on this subject take a look a post I did when Avet reels first came out. Also would reccomend using a silicone based adhesive to attach the steel washers to the inside of the reel . The coeficient of expansion of aluminum is greater than the material the magnets are made of. This thermal expansion variation will cause the bond to separate between them. I learned this lesson the hard way, LOL.
