    Very nice John!  Is the roof rust a paint or chemical treatment?  I am about to embark on a "rust look" project at work. I need to make 50 sq. feet of aluminum panel look like rusted steel. I'm starting by spraying on Rustoleum's oil base rusty ...  more
    I know these are rare, but is it really worth this?

    This would be a perfect candidate for a 3D printer. Maybe someone can sweet talk Mark Dash to add this to his 3D catalog?
    In aluminum or stainless?

    Nice! A "Rotating Transfer Table".  I'll bet a prototype exists, somewhere?  I used custom built 1/8 inch aluminum plating for the turntable at "Cat Dump"  it gets ballast grit between the plates and needs to be cleaned out, if not used for...  more
    Structure Lighting Project
    Playing around with some more ideas using junk on-hand.  I have a few old-school Red LED sign modules. Looking at them I thought they might just fit in an aluminum U channel for use as a 'signal'.  Not a cool operating signal like what Bob is do...  more
    SD60f Build
    Now take 2 of the .02" pieces and 1 of the .03" pieces. I used a scrap of aluminum angle to help glue everything flush. The long sides are the rear and must be flush. Layer the pieces .02/.03/.02.
    Build two of these.
    Now glue the 1/8" piece between the ab...  more
    Stabilizing the Engine House
    I'm leaning toward an aluminum recycling processor. I have been saving aluminum sawdust that would make an interesting gondola or hopper load. Industry could get boxcars with cans & scrap to be processed and ship out gondolas of shredded aluminum for proc...  more
    U channels in concrete?
    My understanding is that aluminum in the highly alkaline environment of curing cement would do quite poorly unless coated with something.
    But here's a thought.... are you running battery?  Maybe no inset at all, just pure concrete, molded.
    U channels in concrete?
    Why not use a single channel, found or built to the correct track gauge, that would eliminate those narrow grooves that stuff could catch and build up in.  
    It being me I would consider aluminum for cost and availability.  The channel would...  more
