CREATING A SPLIT COLUMNS TO COVER EXISTING STRUCTURAL POSTS


YOU CAN COVER A STRUCTURAL POST THAT IS ALREADY IN PLACE BY SPLITTING A COLUMN 
FOLLOWING ARE SUGGESTIONS ON CREATING AND INSTALLING A SPLIT COLUMN

Click images to enlarge

           Fig. 1
DRAW A LINE ON BOTH SIDES OF PIPE TO BE CUT. USE A CHALK LINE OR PENCIL  LINE.  CUT PIPE WITH A THIN, FINE BLADE ON A CIRCULAR OR TABLE SAW. (Fig. 1)

CUT CAPS & BASES INTO HALVES USING A BANDSAW, HACKSAW, CIRCULAR   OR TABLE SAW . (Fig. 2)

  


            
Fig. 2
IN ORDER TO JOIN THE TWO HALVES BACK TOGETHER YOU WILL NEED TO CUT PIECES FROM PIPE THE SAME SIZE AS YOU ARE INSTALLING. (PIECE SIZE: APPROX. 6wide X 10tall) OVERLAP ABOUT THREE INCHES OF EACH PIECE BEHIND THE CUT EDGES OF HALF OF THE SPLIT COLUMN. (Fig. 3)

CLEAN THE LAP JOINT PIECES AND THE INSIDE OF THE PIPE HALVES WITH PVC CLEANER ALONG THE GLUING AREA

 

             Fig. 3
 USE PVC GLUE ON HALF OF THE WIDTH OF THE CUT PIPE PIECES AND CLAMP INTO PLACE.  BE SURE TO LEAVE THE UNGLUED HALF PROJECTING OUTSIDE OF THE COLUMN  SHAFT TO  FORM THE LAP JOINT. (LET GLUE CURE AS RECOMMENDED BY THE PVC GLUE MANUFACTURER.) (Fig. 3

(NOTE: IF YOU HAVE AMPLE EXTRA PIPE, YOU CAN ALSO CUT LONGER OR FULL LENGTH PIECES OF PIPE FOR THE LAP JOINTS)

WHEN THE LAP JOINT PIECES ARE DRY THE TWO COLUMN HALVES CAN BE POSITIONED AROUND THE SUPPORT POST.


STAND IN PLACE BEFORE GLUING TO MAKE SURE THE TWO HALVES LINE UP PROPERLY.


              Fig. 5
TAPE OR CLAMP THE 2 HALVES TOGETHER "DRY" (WITHOUT GLUE) AND PRE DRILL HOLES ABOUT ONE INCH IN FROM THE LAP JOINT,AND ABOUT SIX INCHES APART FROM TOP TO BOTTOM OF THE AREAS WHERE THE BACKING PIECES ARE LOCATED

THIS WILL HELP PULL THE COULMN ROUND AGAIN. YOU MAY WANT TO PUT EXTRA SCREWS FROM TOP TO BOTTOM IN ORDER TO HOLD THE TWO HALVES FIRMLY TOGETHER.  NOTE; THE SCREWS CAN BE REMOVED ONCE THE GLUE JOINTS ARE DRY.  BY PUTTING THE COLUMN SHAFT TOGETHER DRY BEFORE GLUING YOU ARE ABLE TO CHECK YOUR ASSEMBLY ALIGNMENT.

             Fig. 6
AT THIS STAGE YOU MAY WISH TO INSTALL HALF OF THE CAP AND BASE. (Fig.  6 & 7)

WHEN GLUING "L" BRACKETS TO THE CAPS & BASES PLACE ONE HALF OF THE CAP OR BASE ON A FLAT SURFACE, AS SHOWN  (Fig. 4 & 5)   PLACE THE L BRACKET FLAT WITH THE PRE DRILLED HOLES FACING DOWN.  LEAVE HALF THE BRACKET EXPOSED TO OVERLAP AND ATTACH THE SECOND HALF OF THE CAP OR BASE. MEASURE AND SET IN PLACE WITH GLUE AND SCREWS THE HALF CAP AND BASE NEXT TO THE POST TO BE COVERED.  BE SURE TO MEASURE CAREFULLY, AS THE PIPE MUST EASILY SURROUND THE POST TO BE COVERED.

             Fig. 7

CLEAN THE LAP JOINT AND THE INSIDE OF THE COLUMN AREAS TO BE GLUED. COVER THE LAP JOINT SECTION WITH GLUE MAKING SURE THAT ALL SURFACE AREAS HAVE ENOUGH GLUE ON THEM FOR MAXIMUM ADHESION. 

 


             Fig. 8

STAND THE TWO COLUMN HALVES INTO PLACE AND ASSEMBLE QUICKLY WITH SCREWS. SECURE WITH METAL L BRACKETS OR EQUIVALENT TOP AND BOTTOM. (Fig. 8)

 


              Fig. 9

POSITION THE SECOND HALF OF THE CAP OR BASE AND GLUE TO THE PLASIC LBRACKETS AS WELL AS ALONG THE CUT EDGES. TAPE IN PLACE UNTIL GLUE SETS. (Fig. 9) 
 

 

               Fig. 10

WHEN YOU ARE SATISFIED THAT THE GLUE HAS SET, REMOVE SCREWS, SAND OFF THE PLASTIC FROM AROUND THE SCREW HOLES, FILL WITH BONDO OR GLAZING PUTTY (AVAILABLE AT AUTO SUPPLY STORES), SAND, PRIME THEN PAINT. (Fig. 10)

 

 

              Fig. 11

NOTE. IF CAP AND BASE HALVES DO NOT LINE UP PERFECTLY, USE A SMALL PIECE OF WOOD, NAILED OR SCREWED INTO THE FLOOR OR CEILING TO PUSH THE FLARED PIECE INTO PLACE UNTIL THE GLUE HAS CURED.
