Re: Home Build Option 80/20
Tossing around the word "expensive" when talking about aluminum extrusions is silly. Expensive compared to what? Wood? Yeah, it costs more than wood but a 2x4 isn't a fraction as versatile as an aluminum extrusion.
Expensive compared to steel? Sure, it is more expensive by the foot than 1" square tube. But how many steps are there between a raw steel square tube and a finished assembly?
Aluminum extrusions like 80/20 or Bosch Rexroth or Tslot or the Chinese knock off stuff is in a class by itself in my opinion. It is fairly priced for it's versatility, strength, weight, durability, resistance to corrosion, speed of assembly, precision dimensions, etc...
The SEMA van's interior cabinet and all of the framing under the seat weighed in at about 75lbs. Try to beat that for both strength and weight with that particle board/MDF/low grade s**t pile plywood material SMB and VS uses in their interiors.
Aluminum extrusions are easy to work with. You can cut them on a good miter saw with a decent blade, you an machine the ends with the proper set up in a mill or drill press. You can find piles of the stuff in surplus all over the country. It goes together quick, you don't need to paint it, it doesn't rust, it looks clean, not susceptible to water damage... the list goes on...
Expensive? For all that? HA! I think it's a bargain. The weight savings alone would probably pay for the extrusions and hardware through better fuel mileage.
