Thanks so much for the detail K, pretty straight forward. You say
aluminum
is OK. As in not the best material?

I tried both 1/8" ss plate and 1/4" aluminum plate this summer. Unless
you
have a drill press forget the ss. damn hard to cut or drill. On sume
of
the aluminum backing plates, wehere the ss bolts and washes came in touch,
I
used cutout plastic washers made of ice cream containers and liquid
electrical tape.
