[DML] Re: Strut Pressure and Wings-A-Loft

["Toby Peterson" <tobyp@xxxxxxxxxxxx>]

Shannon - The door opening function is divided into two phases:  When 
the latches are released, the torsion bar is wound to maximum stress, 
and unloads itself by starting to open the door.  At this point, the 
strut is not very effective because it has no leverage to speak of.  As 
the door swings open, the torsion bar is becoming more and more 
unloaded, while the leverage for the strut is becoming more available.  
At the very top of the opening swing, the strut is doing nearly all of 
the work, while the torsion bar is nearly (but not quite completely) 
relaxed.  What this all means is that the initial movement of the door 
is almost entirely based on the torsion bar.  There are several things 
that can influence this first phase of the door opening swing; stiff or 
corroded hinges, sticky seals, struts that have contamination on the 
shaft which could cause drag, and any added weight in the doors.

In your case, the first thing I would do would be to lubricate the 
hinges with a light lubricant that won't cause a stiffness in the hinge 
joints when cold (aerosol white grease, silicone spray, light machine 
oil, etc).  You could also check the seals to make sure that they are 
not binding the door at all.  Application of seal dressing spray or 
silicone spray can help the seals to release from the doors.  Wipe down 
the shafts of the struts to clean them, using silicone spray on a clean 
rag.  Try these things, and let us know what the effects are.  The 
struts do not lose pressure temporarily.

PS - There are small spring-loaded door "poppers" that can be used to 
provide a little extra push during the first inch of travel.  If 
nothing else helps your situation, these might be an option.  Reducing 
weight in the doors would also help.
