Step 5 - Top PlateAll thumbnail pictures can be
enlarged by clicking them.
The top plate of this desk is the over sized, very visible
part that sits on the very top of the whole structure. I
made up the blank previously by gluing together two pieces of a
single board that had nice straight grain along one side so the
joint would be easy to hide.
Our first step is to sand the ugly away and
leave a good smooth flat plate to work with. This sanding
is done with the wide drum sander and many, many light passes
that will remove any curvature in the blank instead of mashing it
flat like taking fewer, heavy passes would.
Then I joint one edge smooth, square
and straight and trim the blank to width in two passes, jointed
edge against the rip fence. The first removes all but
1/8" of the waste. The second, light, pass takes it to
finished width and reduces the chance of burning the wood (cherry
is prone to this) on this final clean-up pass.
I mount the big cross-cut sled to trim the
ends to length and square. I trim both ends to be sure
they're both straight and square to both long edges.
With that done I check to see how well
I did by confirming that the width and length are correct and by
measuring across the diagonals to see if the panel is perfectly
rectangular. It is.
Now we begin shaping the top plate.
First I lay-out the cuts to be made in pencil on the plate.
The under-side edges on the sides and front get a 30° bevel
to reduce the visual "bulk" of this plate. I
mount the proper router bit, set the height and depth of cut and
run the panel through vertically.
The first pass takes off about half of
the waste, I'll take two more passes to remove the rest.
I set the fence to leave 1/16" of wood on
the second pass, then make the final pass as a clean-up pass --
again, to remove any burn marks and prevent more by taking a very
light final cut.
Then I swap out the beveling bit for a
round-over and dress the top edges and the lower back edge.
It will have a much shorter overhang in the back, allowing the
desk to sit against a wall, so it gets a slightly different
treatment.
That completes the shaping of the top.
Now I set it in place, measure the overhangs and check to be sure
it turned out right. Looks good, AND it even lays nice and
flat on top of the cabinet.
The final step is to apply cherry wood
filler to the end grain and sand all surfaces to 220 grit.
I'll set this part aside until the casework can be glued
together.
