So we didn't take step by step pictures, but hopefully this will help you somewhat.  I'm always open to explain more.  First step was to bend the steel 4 times--heat it and bend it over something.  We used a 2x4.  Two bends per steel stick, one on each end, trying to get the same shape with each bend.  (There will be 2 strap's per door.)

To make the 'glides' Blair drilled out the same diameter as the bolt to go through the bent piece of steel.  He secured the pulley between 14 washers, 7 on either side of the pulley.  Secure with the nut and that part is done.  We sprayed them with the hammered metal look spray paint, black color.  There is some scuffing once it's all been worked with--so we will have to touch up once it's all done.  The pulley was a nickel color--but we sprayed that too.
