    • Was doing a little research into the origins of napkin building and discovered it was six years ago to the very day ...

      Rick, I like that derrick, quite unique.  I contemplated having a cable operated jib, but decided I would keep it simple since we have a finite amount of time.  I will file this one away for later reference.

       

      ????, Can't get much simpler than a 2 drum hand crank Crab with one line to the boom, raise and lower, and one line to the load, raise and lower.

       

      Oh, the idea is simple, but given the time constraints with this particular build, not sure I want to tackle all those moving parts.  Although, I am designing a single drum double purchase winch anyway for the jib crane.

    • That's a cool old catalog, thanks for sharing it. 

       

      When I built the Foundry building a few years back I Got all the information I needed for the  Stiff Leg Derrick from a 1914 American Hoist and Derrick Co. catalog copy that I have, some really cool stuff in there.

      Here is a picture of the Stiff Leg at the foundry.

      Really looking forward to following along on your build.

    • I personally really like that first one on page 40. Very cool...

    • Part of my Mik build this year will be a manually operated jib crane mounted on the deck of Leroy's Transfer and Warehouse.  In doing some research, I came across this sales catalog from a quarry supplier that among other things sold jib cranes and the associated mechanical and structural parts.  Thought some of you may be interested.  It can be found here: Brunner and Lay Tool Catalog

       

      The jib crane selection starts on page 40

    • Hi Fred,

      No I'm not familiar with the name.

    • Shane,

      I bet that 40' car also had different truck springs as well...

    • I'm working on a 40' car for my work train that has 2 hand brakes. The car is still in use, and was once used on every train.

    • Rooster apologize, he must be drunk.

    • January 2, 2020 8:57 PM EST
    • I apologize as there is mention of the eddy brake system .....

    • January 2, 2020 8:09 PM EST
    • Saw no mention of Eddy Braking but the local library certainly has books on them if one needs to get that in depth with MODELING

      Okay, I need to clarify some stuf.

       

      1. Big difference between passenger brakes and freight brakes is that freight brakes are either on or off. Passenger brakes can be applied, partially released, then reapplied.

       

      2. Hand brakes are separate from the air brakes. They are simply a mechanical brake. And freight cars have 2 brakes on long cars like intermodal wells.

       

       

      Thank you

      Passenger equipment, in the modern days, is often quite different when it comes to braking systems than freight.

          

      Yes

    • This is 2020 correct ?

      As suggested by the experts I TRIED to check out some books from the local library since I model Amtrash.

       

       

      Not sure of Amtrak still has a contract with Knorr but I'm pretty sure they did.

      I suppose it all depends on what era you are modeling?
