Tripod for the 6-inch

The tripod  comes out of the
suitcase unassembled.  It bolts together
using carriage bolts at the top of each leg .

 
The whole thing is made of poplar.  A
lightweight hardwood with some flexibility.
Each leg is made from two 1.5"x0.75" strips
about 22" long.  A 1.5" square spacer  glued
in the middle keeps them apart.  A #8 bolt
at the bottom squeezes the strips together
and provides great rigidity.

 Each tripod leg has a hinged arm
that meets in the center to bolt onto a
small hexagonal piece of wood using
wingnuts.

This arrangement proved very stable.

  The top of the tripod has three
  teflon pads for the azimuth bearing.
  They are much too big based on  
  the fact that the bearing is VERY
  smooth and the calculations in the
  Kriege/Berry book suggest that the
  size of the pads should be about 3/4"
  square.

This type of tripod would be good
for any use.

   The rocker box bolts  onto  
   the tripod with a 3/8" carriage  
   bolt held loosely in place
   by two nuts tightened onto
   a lock washer between
   them.
