Bistro Table, Part 3: Leg Shaping and Glue-up

The undercarriage of the table looks like this:

The uprights get a long cove and the feet and top supports get some straight cuts.  The shaping of the uprights was straightforward.  I used a thin, bendable stick to mark the curve, starting and ending about 1/8" from the bridle joint miters.  Then I made some relief cuts,

chiseled out the waste, and cleaned it up with a spokeshave.

The feet and top supports were easy - just a couple of straight saw cuts, followed by cleaning up with a plane or chisel.

After final surface planing of these parts, I did a dry-run of the glue-up.
Extra clamps make sure the feet and top supports are seated against the uprights
Did my best to ensure things were square, but I knew I could plane to squareness later.

Four leg / foot / top support subassemblies in the clamps
When the glue had dried, I cleaned up the joints with a smoother.  I re-squared the parts that would support the top.  I'll be using some leg levelers on the feet, so it wasn't necessary to ensure squareness there.

Marked one end as "top supports" and squared them
The four legs will be glued to a center "post".  I started by gluing two leg subassemblies to the center post.  Curved cauls were helpful in clamping the curved leg parts.

When that was dry, I glued on a third subassembly, and when that was dry, the fourth.

Glue-ups are almost always interesting, in that you have to really think things through.  It was a small challenge to find good ways to clamp this up.

And here is the result - the undercarriage is complete.
All glued up
Next time: a really interesting exercise in making the subtop.
