With the banding done I can now go back and clean up the
round over/banding intersection. As I
said before this is all done with hand tools like a rasp, file and
sandpaper.
Before & After Closeup of Leg Roundover Blending |
Not hard, just time consuming
since there are 44 of them to do. It
takes about 45 minutes per leg to do all the cleanup and blending.
Before & After of Leg Roundover Blending |
The legs are nearly done, just the applique pieces need
to be added but that won’t happen until much later in the process. Since they are stained with a different mix I
will need to do the legs first then apply the applique pieces.
Completed Legs |
Leg Applique Size Testing |
With the size decision made I took the random width
applique pieces, ripped them all to a constant slightly oversize width and ran
them through the thickness sander again using a fairly fine 220 grit
abrasive. While none of the pieces had
gone really crazy there was some minor cupping in a few. So with everything now flat I stickered them
for air flow and set them aside to see what happens.
Rough Cut Applique Pieces |
Next is to select the material for the four aprons. I found a single board that I can get all
four pieces out of and have very little waste.
Fortunately, the knot holes at the right end are outside the area that I
need.
Apron Layout |
I started out by rough cutting the board to length about
an inch long then ripping those pieces to about ¼” too wide. I let them set overnight to see if they are
stable. The next day I ran them through
the thickness sander to flatten and get rid of the planer scallops. With that done I set them where they go in
each leg. This gives me an idea of what
the table will look like. Fortunately, I
had two left and two right legs – they are mirror copies of each other. I know it sounds silly but it can happen that
you end up with 3 left legs and one right.
Test Fit of Table Rails |
While the side rails are stabilizing I pulled out some
more oak for the top arm rest picture frame and the 4 pieces that will form the
sides of the well leading down to the playing surface.
A little creative layout got the pieces I needed out of a
couple of boards.
When I went to cut one of the boards to rough length I
noticed that it looked cupped. Setting a
straight edge across the piece confirmed my suspicions. Actually it was not any great feat of
observation as the board was cupped almost 1/8”.
Cupped Board Inner Rail Board |
Since I was going to rip it into narrower pieces I was
not too concerned so I went ahead, made my rough cuts to length then ripped to
rough width. With that done I set the
straight edge on the ripped narrower pieces and found the cup had been reduced
to less than 1/16”.
Rough Ripped Inner Rail |
That small amount I can take out with the thickness
sander and at the same time remove the planer scallops.
Inner Rail After Flattening |
When ripping boards to width sometimes the cutoff piece
on the outboard side of the saw blade right at the end of the cut will end up
with a little bump as shown below. They
are not always this big but frequently they are there.
Cutoff Piece with End Nib |
If the piece is scrap, then it’s no problem. However, if you are going to use that edge
against the rip fence to cut another piece then it’s a problem. As you make that next cut everything will go
smooth until that bump hits the back edge of the fence and that’s not good. If it’s big then it can stop your forward
progress leaving you holding the board with the saw running and no real option
except to turn the saw off, wait for the blade to stop, remove the board, get
rid of the bump and recut the piece. If
it’s a small bump it can cause worse problems in that it can cause the board to
shift toward the blade allowing the bump to continue on down the fence face and
giving you a taper the width of the bump from the point it hits the fence until
you finish the cut. Now instead of
parallel edges you have a taper at one end.
For my saw I would have the last 18 inches of the cut tapered. Imagine if you are trying to glue up pieces
for a table top with one tapered end.
You end up with gaposis and bad words being used. The cure is to keep an eye on the cutoff and
if there is a bump get rid of it. I use
a knife or a scrap block with some 120 grit sandpaper fastened to it with spray
adhesive.
End Nib Removed & Sanding Block |
With these parts cut it pretty much completes the rough
cut work for the exposed oak. There is
still the structure and interior bracing needed to support the sunken playing
surface. For now, I am going to let the
rough cut pieces set and see if they are stable. I will pay particular attention to the cupped
pieces to see if they are done moving around.
