Assignment Make something BIG

Target and References

After a long discussion, I decided to realize a foosball table from an inspiration of an old foosball table at the D9 pub located near the school.

First of all it is necessary to scan the real model and find some reference on line.

This is the 3D scan made with a structure sence. I used a 3d model as first reference.

This is the reference I liked more and appointed to be the model for the style of the design.

3D model

I started designing a table 3D model from the design reference and the 3d scan. I also found in internet some technical data about the standard regular dimension.

Here it is some screenshots about the project and some structure parts

Milling

The 2D drawings are ready to be milled. I am waiting for the delivery of some mechanical parts that I could not accomplish in DIY.

Milling Machines Parameters cut depth 50% of the pannel thickness (here 7,5 mm OSB for pannel 15 mm)

Laser Cutting

For the lower part of the table I decided to design and laser cut a cover by a bending pattern. The surface is 1,5 square meter 3mm thick of playwood: let's laser!

Assembly

Press Fit Joint... It need to be pressed with all the kindness you have!

Tolerance
Press fit female: 0,5 mm offset

The assembly phase is very important (and a bit stressfull). Care must be taken of the correct sequence of steps. First the bolts, washers, wood frame, and then again the washer and finally the bolt.
