Parts of a door for forensic scientists & barristers

Colonel Johannes Vermeulen with Oscar Pistorius bathroom doorDay 8 of the trial of Oscar Pistorius, charged with the murder of his girlfriend Reeva Steenkamp, included the testimony and cross examination of Forensic investigator Colonel Johannes Vermeulen (pictured above).  Vermeulen’s investigation centres around the condition of the bathroom door and the baseball bat which Pistorius says he used to break down the door after the shooting.  A vigorous exchange over the height of the perpetrator ensued.  Vermeulen maintains that Pistorius would have had to be on his stumps (contradicting his statement) to make the observed marks, so the defense attorney Barry Roux attempts to pick apart every thread of his evidence, including what happened to the missing shards of timber (seen lying on the floor in the crime scene photos), and could Vermeulen balance upright on his knees in front of the door with his feet raised behind him (he tried and couldn’t).  Anyway, Doorstuff’s attention was drawn to this court session when it was apparent that no-one, even Vermeulen with 29 years experience in Forensic Science, accustomed to giving evidence in court, could name any of the parts of a door.  Thus there was much pointing, stepping in and out of the witness box and botched descriptions, for example “this part of the door”, or that part, “the edge of the door”, “no, the frame of the door” etc.  So although it is undoubtedly moot now, Doorstuff has made a diagram (below) for forensic scientists and barristers giving just a few of the basic terms relating to a mahogany two panel bathroom door like the one in question.

Q: How do I determine the overlap required for the door compared to the opening for my sliding door?

March 18, 2011 by · Comments Off on Q: How do I determine the overlap required for the door compared to the opening for my sliding door? 

A:  It is an aesthetic decision, but perhaps between 20mm and 100mm each side.  Slightly more overlap might be prefereable, as this may help reduce noise transference between the rooms.  The dimensions of your existing architrave and skirting boards will affect the distance off the wall that the door will run, so bear in mind that may present an additional gap for draughts and light to escape through and affect the finished look.

Does the Rollan sliding door track cause the doors to sit proud of the door frameor architrave, or do you sell spacers to bring the running gear forward?

If you’re using double doors to part and slide alongside a wall either side of the opening, and the opening has architrave/frame protruding, the doors will have to pass that and thus will stand out further than otherwise.  The wall brackets which come in the Rollan kit do not act as spacers, and so you could perhaps consider making a wooden baton and fixing the track to that.

Can a door closer arm be fitted to a curved architrave?

When an architrave has moulding or curved features where the foot of the door closer arm is supposed to go, one usually chisels out a flat surface to screw the shoe on to.
