    Bill,

    Impressive CAD model.

    Is there any part of this project you want me to focus on to get you a quote? How much of the project do you need me to quote on (all/partial)?

    Once I get this information I will get with my estimators to see what falls within our capabilities. 

    You can email me at: bryan@mezcofab.com (this is also the e-mail associated with our Pro account)

      In addition to the drums, the planetary gearbox, associated shaft and dog clutch need quotes. There are also a number of weldments for things like the fairleads, X-Wind Box and frame.

      OH, yes, the parts of the Sprag clutch need quotes.
  • No, 7075 T6 is not weldable.  Understand that this drum will be under EXTREME stress.  With 10,000 feet of rope wound on at over a ton of tension, the crushing force is about a million pounds.  The drum design has undergone a long series of FEA runs to arrive at a geometry which will survive this stress.

    What can be done to enhance manufacturability is to enlarge the ID in order to permit easier access by a cutting tool.  Then two rings have to be made to restore the original geometry.  The rings will be installed in the enlarged ID using a thermal interference fit.  This means chilling the rings to -191C in liquid nitrogen to shrink them so they fit easily.  When the temperature equalizes, the rings are locked in as if they had been welded.

    Bill,

    Would you allow making the aluminum drum in 3 pieces and welding them together? 2 ends and a center section?

    We have a Pro seat at Mezco. We have CNC lasers, water jet,HD plasma, along with Haas Mills and lathe. We also have full fabrication with CNC bending and welding. Not sure what you need but could take a look at it and get you a quote if it fits our capabilities.
