Computer-Controlled Machining

Chess table
Make something big was the assignment this week. I was in a way a bit relief to get a week of from programming and do some design work.
My idea was to make a table but I didn't like how unoriginal that was so I thougt about making a board game table. To keep going with the chess theme I have been doing the last few weeks I made the table foots out of a chess pawn. The top part of the table has 4mm engraved out of it so I can put a 4mm wood with diffrent board game in it. I did all this in a ShopBot and all the design was done in Inkscape and PartWorks.

The first design of the table had four feets connected with small bits like a puzzle. After I cut that out the bits wern't connecting each other like I wanted to so I thought of another idea to make the table stand.

Here is a picture of the first design of the table

Next thing I did was that I found a good picture of a pawn on the internet and I traced it in inkscape. Now I made two bits on top of the other one and then I made other two bits in the tabletop, so the feets should go right into the top.

Here is a picture of the design

I cut this out in the ShopBot and used 5,7mm end-mill drill. Just make sure that you do Fillets in PartWorks. If not the drill is not going to take the cornest correctly. The Fillets makes the all the corners bigger and puts them in a circular shape. A circular drill is not going to drill out a 90° corner.
You can't see on this design that on top of the table is a box wich is 32cm x 32cm. This is the box I engraved out so I could put in a diffrent types of board games.
This design is 60cm high and the tabletop is 50cm.

Here is the table after the shopbot cutting
The lighter wood is going to get rastered in a laser cutter with all kinds of board games

Now I began the board game desing. The first two board games I wanted to try out where Chess and Backgammon. After I designed it in inkscape I rastered it in a plane wich was 32 x 32 cm (just like the engraved part on the tabletop).

Here are the rastered board games:

Like you probably noticed on the blueprint abow I made two holes on each corner of the table top. These holes are there to help you take the board game out and change it too a new one. You simply reach under the table and push your finger trough the hole.

And finally here are some pictures of the outcome.
When I have time I will paint it and then maybe make more games for it
