• Lumber Choice

  Joni • 07/18/2017 at 12:08 • 0 comments

  After despairing of finding a straight 2x4 I bought some better quality construction lumber

  C18 they are 45x70x3000mm reasonably straight and with a smooth surface

• Main dimensions

  Joni • 07/17/2017 at 18:00 • 0 comments

  Separation between the inside of the wooden structure needs to be 450+(56*2)

  That's 450mm separation between the inside of each rail plus 56mm for each rail.

  19-inch rack details
  

  That's 564mm in total.

  Height of the total rolling desk/cabinet is determined by what can roll through a standard door.

  
  

• Hideaway details

  A little massaging in OpenSCAD and the desk takes shape.

  Working out how the hideaway mechanism will work and whether it will fold out to create additional desk space will be key to this projects success and how easy it will be to create.
  

• Modelling additional detail

  Joni • 10/28/2016 at 13:20 • 0 comments

  I've added the monitor support to the model v3 and you can see that there will be a need for external structure to support the sheeting around and also some serious thought needed if this is going to be a hideaway desk.

  Also some careful measurements to see what amount of protrusion is needed in front and behind the servers to manage the cables etc and cover them nicely with a door.

  I'm also concerned regarding overall stability.

• Dimensioned Model

  Joni • 10/28/2016 at 12:30 • 0 comments

  Right so i've now created an OpenSCAD model of the structure to hold the rails and the rails with the correct size holes and hole spacing.

  It's an interesting exercise and it shows the full size of the desk frame.

  Hopefully I can create the bridle joints in the model as well at a later date and perhaps work out how I want the remainder of the desk to look.

• Rails

  The rails in the rack I bought seem to have an unusual profile. Not right angle and not quite the same as double angle rail either. Total width is 56mm by 120mm deep.

  I've made a rough OpenScad module for the rails to ensure I allocate enough space for them. Measurments wern't really used. It's just a rough guess.

• Modelling the Desk DraftSight vs OpenSCAD

  Joni • 10/27/2016 at 13:52 • 0 comments

  Did a little bit of modelling using Draftsight to rough things out and also had a little bit of a play in OpenSCAD.

  If I can make OpenSCAD do bridle joints it could be a nice way of modelling the desk.

  All elements are 2x4's (35x89mm)

  Internal space is 935x450x600mm which is sufficient for a 21u 4-post 19" rackmount setup.

  If I get a chance I will include the double angle rack rails in the model.
