line thickness and ScatterPlot3D

I am using the the following command on a set of data:

hLines = ScatterPlot3D[ hComps, PlotJoined -> True ]

and then I am defining some axes using the following sort of
cammands:

e1={{0,0,0},{1.5,0,0}}; e2={{0,0,0},{0,1.5,0}};	e3={{0,0,0},{0,0,1.5}};
PO = {0,0,+1}; PP = {0,0,-1};
PFp= {1.000000,0.000000,0.000000}; PFn= {-1.000000,0.000000,0.000000};
PUp= {0.000000,1.000000,0.000000}; PUn= {0.000000,-1.000000,0.000000};

q = Graphics3D[ {Thickness[0.0018],
                Line[e1],Line[e2],Line[e3], 
	            PointSize[.01], 
	            Point[PO],Point[PP], 
                Point[PFp],Point[PFn], 
                Point[PUp],Point[PUn]
             }]


The problem is the following...

When I Show hLines and q using the following:

Show[ q,
      hLines,
      Boxed -> False,
      AmbientLight -> GrayLevel[1],
      PlotRegion -> {{-0.4, 1.3},{-0.5,1.3}},
      ViewPoint -> {2.186, 1.700, 1.945}
    ]

the line thickness for the hLines is much too thick.  If I make
all lines thin from the Graph menu (sorry, Mathematica 2.1.0.2 on
a Quadra 800), then ALL lines are made thin and the lines and pts
I defined become too thin.  I don't seem to be able to set the
line thickness on the Graphics3D object generated with ScatterPlot3D.

Can someone help me?

Thank you.
