The new upper base is dry and marked, so I cut the circle out on the bandsaw.
I sanded the edges on the spindle sander, taking the edge down to the pencil mark.
I set the 3/4″ round-over bit back in the router and trimmed the top edge.
I sanded down both the upper and lower bases.
I did a dry-fit to make sure the columns fit as planned.
Then I realized that the outside dimensions of the columns was 14-1/2″ when measured across the top. The rim around the dome is only 14″. I really should have had a more detailed plan than a pencil sketch that took 30 seconds to draw…
I set the table saw blade at 10 degrees, and carefully ran the columns back through, taking off another 1/4″ so the columns would fit beneath the dome.
Its tight, but it worked.
Next step is to put the walnut bead around the columns.
To do this, I ripped a piece of walnut down to 5/16″ x 3/4″. I placed a 1/8″ round-over in the router table and rounded each outside edge.
When all four edges were round, I ripped the piece in half. This gave me two tiny pieces of trim.
In order to cut these tiny things, I created a sacrificial base and back board for the miter saw. Otherwise, the 3/4″ and smaller pieces I need will get shot off of the saw. Setting the miter saw angle to 22.5 degrees, I began cutting my tiny trim.
I clamped a spacer block in place and glued the first piece in place, then pinned it there to dry. When cutting the trim to length, I often had to tape down the short end, so the blade wouldn’t pick it up and throw it because it was so small.
My longer pieces are about 5/8″. The two shorter pieces are about 3/16″ long. To make micro adjustments, I sanded the angled face on 150 grit paper.
In the end, I did manage to install one of the bands, but it is nearly 1:00 AM and I am too tired for this detail work. I just wanted to make sure that it was possible.
