Quantum Tunneling DEMO - Part 4

This general assembly table will solve problems with unaligned pieces of DEMOs and makes it easy to keep everything together.

This table was originally created to help with steady and alligned locations for holders for a laser and prisms to make it possible to create a quantum tunneling effect.

P.s. As can be interpreted from the text above, this is part of a bigger project where we (Larissa Krab and Mark Lemmens) worked together with Helen van Rooij.

The following materials are needed:

• Plywood
• 1 plate of 6 mm thick, with pin holes
• 1 plate of 6 mm thick, without pin holes
• Lasercutter to cut the design
• Wood glue to glue all the layers together
• If preferred:
• 4 screws with a length of 14 mm, instead of the wood glue
• At least 2 big elastic bands, instead of the wood glue

For a general assembly table to come to be, a design is needed.

The solution to keep it easy consists of an 'IKEA-style' idea where there's basically pins that go both in the table and the part you want on the table in a specific place.

The workplace where we get the supplies from, Makerspace, only has certain thicknesses available. Because of this, the decision was divide the table into multiple layers: One layer with holes and one layer without, both 6 mm thick.

Handy tip: For the pins, we recommend they have at least 1.5 x the height of the holes in the table if you want your pieces to be secure enough.

NOTE: This design was made with a specific size in mind. If different numbers are needed, you can use the Inkscape files and alter the values.

With this step, you can just let the lasercutter do its job!

Now that we have all parts required, there are three ways to put the table together.

The first option uses wood glue where you simply put all the layers - alligned! -on top of eachother with some wood glue in between.

The second option needs 4 screws of 14 mm. This can also be seen in the sketch provided earlier, as this was the original idea. Here, it is possible to disassemble the parts.

The thirds option is mainly meant to consider if the budget is very tight and you want to keep all parts unharmed. You have to place the two layers on top of each other and put the big elastic bands over them to keep them together. Try to not cover any pinholes.

And there it is! Your general assembly table, ready to be used for all kinds of DEMOs!
