How To Construct An 8″ Round Table With Lazy Susan Part 1

This series of posts will show the construction process of the 8″ Diameter round table will an inset lazy susan.  Following are 2 drawing of the basic math and cross section of the top.

Table cross section

 

An important step is to build a platform without any twist (wind) that would translate into the top. Cross site the 2 levels and shim till they line up.

Making sure there is no twist

We built a flat framework to be roughly 6” inside the finished table OD.

 

2 sheets of 1/2”  multiply form the center layer of the core.  They were joined using Lamelloes and glue. The finished top will be 2 ¼” thick with 7 layers total.  With resin-impregnated honeycomb used for 2 of the inner layers, it becomes a torsion box structure.  Some of the tables I have built in the past have been so heavy that you have to get a crew of young men to move it.  The goal was to build a top that could sit on a minimally sized base and have its own structural integrity and be light enough not to have to get the young boys to move it around.

Eryx making sure we do it right

From our center point, the circles were drawn and the outer edge routed.

All the poplar framing that gets glued and stapled to both sides could then be flushed trimmed with a bottom bearing router bit.

The inner circle was routed on the first side through the poplar and halfway through the plywood.  It was then cut out with a saber saw and flush cut after turning the table over to do the framing on the 2nd side.

Adding the framing

We divided the circle into 12 segments for the framing and for compartments for the honeycomb material.  We used a long thin tape measure around the outside to easily do the layout.

Cut almost through

Ready for the honeycomb

This last picture shows the top with all the framing and ready to cut in the honeycomb material. We put in an extra batten over the plywood joint for a little extra stiffness.  The ¼” layer will go on crosswise so as not to create a hinge line.

If there are any questions on specifics I would be happy to answer.

Very nice, What will that top weigh when it’s done? How are your shop sawn veneers glued to the substraight. You sure do beautiful work.

I haven’t actually figured it out. The stone lazy susan will be separate, along with its bearing and base ply, for moving and delivery. I am still debating on the glue for the veneers to substrate. It is either going to be 3M Fastbond WB contact cement or Unibond 800. The veneers are edge glued with hot hide glue.
