Another Coffee Table: Rounding the Ends
When
we left off, it was with the carcase together ...
Step
1: clean up the carcase
Low
angle plane for the end grain and cross grain ends ..
Then
the face grain top and bottom ..
And
I had a chance to use a small BU infill smoother I made several years
ago on the edges. Perfect for one-handed smoothing ...
Step
2: Time to round the ends.
In
the test piece, it looked like this ..
This
lacked the inside hollowed filet. The build today starts with the
making of the filet.
The first decision was that this had to
be made of end grain. If it was made of side grain, the sides of the
filet would be end grain, which would clash - darken - with the side
grain of the carcase when a finish is applied. Fortunately, I had
this one last offcut. Just enough ...
The
filet is triangular with a hollow on the outside. I first tried
shaping this with a hollow plane on a sticking board, having sliced
off a triangular section on the table saw. It was impossible to do.
No way to hold the wood and plane it. I tried a number of variations.
I won't go there. They were all impossible. You do it, you're a
better man - or woman - than me. You're probably better
anyway
Finally
I came up with this. Start with ripping a 45 degree bevel on the
table saw (slider here, with board held in a Fritz and Franz jig)
...
The
router table is set up with a round nose bit ...
The
mitre can be run past this and the bit will shape a round hollow
..
Now
slice this off on the table saw ...
I
made a bunch of them (as they are a little fragile) ...
Before
glueing them in, each was sanded - 80/120/240 grit on a dowel, with
the filet held on the sticking board ..
The
filets were then glued in (Titebond hide glue for everything). A
dowel was used to place pressure evenly on the corners ...
Step
3: shape the ends
I
used a larger washer than this one this time to mark out the curve
(as the radius needed to be reduced) ...
Then
began planing ...
Refined
with a block plane ...
...
and finished with sandpaper.
That's
it for today. Next I begin the tapered and splayed legs.
