8" Solid Tube Dobsonian

 

 Here are the photos of 8" Solid Tube Dobsonian.  I've photo-documented the building process and will be adding photos soon.  Stay tuned.

 

Thanks to Chuck Dethloff (Telescopes and More) for the use of his excellent design and excellent advice.

Building the 8" Dobsonian

 

8_raw_rocker.jpg (44827 bytes)  This is the raw rocker box.  I used Baltic Birch, instead of the Apple Ply I normally use for scopes.  This wood is just as nice, but brighter in color.

 

8_Ebony_star.jpg (41993 bytes)  Cover the bottom of the rocker box with Ebony Star laminate and it glides like grease on the ground board's virgin Teflon.

 

8_ground_board.jpg (160160 bytes)  Here's the ground board.  Place the Teflon right above the feet so as to steady the scope by relating the weight and stress above right into the ground.

 

8_rings.jpg (45630 bytes)  The Altitude bearings are shown here.  The cradles are already stained with the cherry stain.  Use gloves when staining.

 

8_pieces.jpg (43860 bytes)  Here are the stained components drying.  After the stain soaked in, I applied a couple of coats of a water-based varnish.  I normally use marine spar oil-based varnish.  We'll see how the protective coating works.
