   If I play with this I'd probably want to come up with something really   
   fast.  This is not for any kind of load chain.  Maybe not even a   
   decorative load like a lamp.  Its just one of those things I want to   
   play with, like a 3D printer.   
      
   For loads I have 4 3/8 load chains and chain binders.  I put each load   
   chain in an ammo can for easy hauling.  Two will fit, but its a little   
   heavy with two.  I also have a bunch of those 3700/10000 ratchet straps.   
     The last several vehicles I've hauled I used ratchet straps, but I   
   like chains when I haul my tractor.  I always used chains on my scissors   
   lifts too, but I sold those when I quit contracting.   
      
   No, this is just playing.
