[Rhodes22-list] Boom Room Update Feb 3

[Arthur H. Czerwonky]

Dave,

With 7/8 SS from West figure $45. for a 6' length, which I use.  Prop. higher cost, based on length, which could be as long as 20', fore and aft on each of two sides, therefore 2 each.

With 7/8 SS a cross member, probably 5.5' in length to 'spread' the two other tubes, above.  If the fore and aft dimension is 6' or less, one in the middle can do well due to the SS rigidity.  If F&A is greater than 6', additional braces are suggested, therefore 1 each or more.

7/8 SS connector, various, therefore 6 each at about $15.

Sunbrella top material, if used, 60" width of desired color @ about $25/yard,  8'+  for a 6' long top, providing 1' surplus flap necessary for front and back.  Therefore 3 yards @ about $25.

Labor cost not that bad.  Storage, assembly, and disassembly quick and simple.

There, you have a nice BR or Bimini top, lacking only a few lines to tie the four corners.

See what I mean about putting together the BR for a very reasonable cost?  We could make it more complicated and costly, but I can't imagine why.

The side drapes are simpler still.

Your thoughts?

>then begin to explore vendors.  Does anyone have an idea for a metal
>bender that could work on a prototype?  Comments on the benefits of
>metal vs. plastic vs. carbon?
