  1. To Make Something Big


Deciding what to make

I decided to make a chess table & two stools. First I prepared the rough sketch of my design on paper. As I am still learning the solidworks I decided to keep my design simple

3D design in solidworks - Designing Table

First I designed two parts for table namely "table top" & "table leg" asshown below:

Then I prepared assembly from these parts. Here is the final table assembly..

3D design in solidworks - Designing Stool

First I designed three parts for stool and then I assembled Them..

Creating Layout File

Here I created a plate of 5 feet x 5 feet and then put all parts on this plate Using this method we can create layouts in solidworks assembly

Creating DXF file

In solidworks, we cannot export assembly directly into dxf file. However, it is possible in part mode. Hence I have created Drawing file (.SLDDRW) then exported it to dxf from drawing file.
Here is the dxf file..

Cutting the parts & assembling them

We used a canadian make router with following Specs:

Then, I received all the cut parts..



As shown below, cut edges were not sharp. So first, I polished all the cut-edges using a wood polishing machine.

Smaller wood polishing machine
Larger wood polishing machine


Here is the result of polishing...

Before polishing
After polishing

After this, I assembled all the parts. Here is the Hero shot of assembled chess table & stools...
