Digital model of the 3L Table.

 

I modeled the table in Rhino using Grasshopper to generate the geometry

for the top. Rendered in Bunkspeed Hypershot.

A view of the underside of the table. This view shows the laminations of the plywood as the thickness changes from 3/4" at the mounting point to 1/4" at the edge.

Bits to Atoms...

 

I used the CNC I designed and built to cut the pieces from MDF.

Material ruled the decision to make the table 24" tall : )

Overall view of the milled pieces.

 

The 3 legs are milled as 6 halves and glued together and then sanded smooth.

Prototype pattern for casting.

 

The prototype after being glued together and sanded smooth. The prototype uses superstrong neodymium magnets embedded in the MDF to hold the legs together.

Prototype at the foundry.

 

Image of the painted leg patterns at the foundry. They would make sandcasts from these patterns to produce copies in aluminum

Pouring aluminum into a sandcast mold.

 

I got to watch the people pour aluminum at Seaport Casting in Toledo, Ohio. Hopefully in the future, I will be able to pour my own metal using a DIY aluminum foundry also in the works : )

Aluminum pieces!!!

 

I received the pieces back with the prototype. I plan to sand the aluminum pieces smooth.

3L Table Diagram.

 

I started to sand one of the legs. This image shows the differences between the three legs.

Legs of the table.

 

Here you can see the difference between the one I started to finish and the untouched finish of the sandcast.

 

 

I hope to have more updates soon!!!
