Mc-Master Carr (http://www.mcmaster.com) has all this sort of thing,
delivered to your door a couple days later, but it's not necessarily the
least expensive source. Use it when you can't find another source, and
you're tired of hunting.
>Stainless Steel screws/nuts/washers
Good hardware stores. Marine suppliers. Look in the yellow pages under "bolts"
>Aluminum Plates
Look in yellow pages under "metals" for a local supplier. Home Depot,
Lowes, and their ilk have limited selection of this. But, what you're
really going to want to find is someone who can do some fabrication for you
(shearing/cutting). The metal supplier might have references, or ask
around at places that are doing custom car and motorcycle fabrication. If
you find someone who has access to a big bandsaw, plasma cutter, shear and
so forth, you're a lot farther ahead.
>Tapered Aluminum Tubing
Tapered? Or just nesting? Max Gain (http://www.mgs4u.com/) has stuff like
this, as does your local metal supplier.
>Anti-Oxidant coating
hardware store
>Sealant Tape for connectors
hardware store or electrical supply or McMaster-Carr or somewhere like
Newark electronics, Mouser, or Digikey
>Stainless Hose Clamps
hardware store
>Stainless U-Bolts
a little tougher to find, but anywhere that does signficant amounts of SS
hardware (yellow pages for bolts) will have these. Mc Master Carr
