Note: Before exposure to weather. wood parts must be painted with two coats of high-quality OIL-BASE or ACRYLIC-LATEX primer to maintain warranty coverage.

Measure the total distance from the bottom of the beam to the platform, minus the combined heights of the cap and the base.
|
|
An easy way to accomplish this is to stack the cap and the base on the platform, then measure from the top of the cap to the platform.
|
|
Measuring from the neck ring and using the saw kerf line, trim 3/8" to 1/2" from the top of the column to provide a square end from which to measure.
|
|
|
|
|
|
|
Use a rasp to level off the cuts so the weight will be evenly distributed across the surface of the column.
|
|
Measure from the newly trimmed to of the shaft to the proper length and make a series of marks around the column shaft.
|
|
Using a piece of cardboard as a guide, draw a line all the way around the shaft.
|
|
|
|
|
|
|
Use a fine-tooth saw to cut the column. Cut through the wall and roll the column to accurately follow the line.
|
|
Using a non-fibrous, solid-drying asphaltum-type roof coating, paint the inside of the shaft from the bottom up, as far as you can reach.
|
|
Paint the bottom cut end of the shaft with an oil-base or acrylic-latex outdoor wood primer.
|
|
|
|
|
|
|
Paint the top cut end of the shaft with an oil-base or acrylic-latex outdoor wood primer.
|
|
Using a jack and post, jack up the beam only enough to remove the existing post, no more than 1/4".
|
|
Determine the top center line and mark it on the beam.
|
|
|
|
|
|
|
Hang a plumb bob from the top centerline to determine the bottom centerline.
|
|
Mark the bottom centerline point.
|
|
Using a square, draw a centerline perpendicular to the outside edge of the platform.
|
|
|
|
|
|
|
Draw a centerline parallel to the outside edge.
|
|
Mark the centerline on all four sides of the base to assist with alignment.
|
|
Center the base on the centerlines on the platform and draw an outline where the base will sit.
|
|
|
|
|
|
|
Mark the location of anchor pins in the corners of the base outline -- 1/2" from either side. Mark for two pins in diagonally opposite corners.
|
|
Drill pilot holes for the anchor pins.
|
|
Place the anchor pins in the platform pilot holes.
|
|
|
|
|
|
|
Center the base on the bototm of the shaft. Use a couple of finishing nails to temporarily hold it in place.
|
|
Drill pilot holes through the remaining two holes in the base.
|
|
Using the pilot holes, attach the base with two 2 1/2" corrosion-resistant drywall screws. Remove the nails, drill pilot holes, and install two more screws.
|
|
|
|
|
|
|
Position the shaft-base assembly over the two anchor pins.
|
|
Use 2" finishing nails to secure the cap in place on the beam.
|
|
Drill four countersunk pilot holes through the edge of the wider portion of the top of the shaft into the cap.
|
|
|
|
|
|
|
Drive four 2 1/2" corrosion-resistant drywall screws at an angle through the wider portion of the top of the shaft into the cap.
|
|
Seal the seam where the shaft meets the cap and the base with a 30-year, paintable, siliconized caulk.
|
|
Fill countersunk holes with an outdoor wood putty.
