      Mik's 2018 Joe Bussing

      I will attempt to build an early 20th century wooden oil derrick. After doing some reading and internet searching I've come up with the initial design for the tower. Everything seems to be based on that so I'll build it first. These derricks were typically built out of 2X12s with bracing every 8 feet. Typical height was 72 feet so when I scaled it out it was three feet high! I'll have enough wood, but will have to take stock of what is left after its built. I'd like to incorporate a platform, walking beam and some piping.

      I am using a 7 1/4 by 3/4 redwood fence plank. It's been in my shop for about a year so it should be dry and hopefully won't be subject to a lot of warping. I'll need to cut off and dispose of a 1/4 inch strip in order for it to meet 2 X 4 square inches (1.5 X 3.5 = 5.25 square inches).

      Tomorrow I'll strip the wood for the tower.

      It's been awhile since I've posted a picture so here goes. Here is a preliminary sketch of the tower.

      It worked! Here is a picture of the three foot diagram I'll work from.

      Joe...   Typically the length of drill pipe was 30 Ft.  During the drilling process..  The derrick had a cable hoist that was fed down thru the top pulley and picked ..Up the horizontal pipe off the drilling floor and stood it up vertical and it was then screwed together to the last piece in the hole to create the string.  To get the new pipe vertical, on one side of the derrick the cross bracing was way higher up the side then the other 3 sides,  to allow for clearance as the pipe was stood up. 

       

      This area also allowed the removed pipe to be extracted from the middle of the rig when needed.

      That's good to know! So I should leave room for a 15 inch pipe (1/24th scale) to be hoisted from horizontal to vertical on one side of the derrick.

      Yup.. Up thru the legs of the derrick.

      Thanks John.  This helps. I'm still trying to figure out the cabling and drive belts.

      Well, if the bore is done, and the well is now pumping oil, then you don't need the cables and pulleys. That's the way I built mine, when it was producing and most of that extraneous stuff had been removed.
