i might miss the 'ol mooneye, but, i have a replacement.
all parts i had on hand so material cost: $0.00.
1-8th stainless sheet stepped up to offer some material for the attachment:
discs were cut out a while ago:
basic shape:
centers located:
cinched down, tight fit and rigid due to the bends. screw welded in center:
used welder on high to burn a center hole. welded stainless washer to hole on inside. warped some so beat it out.
there is no bulge. it sits flat against rim lip and brace i added.
nut was a stainless wingnut, removed wings so need pliers to remove:
just hope it's balanced. everything was measured by eye ball, no measuring device. took about an hour to get it fitted because the disc was waiting already.
