It has been a while since the last update and video has been released.

In this final episode of the DIY vacuum table video series the components of the table are assembled. Furthermore, some final preparations are done, e.g., cutting holes and threads for further work holding features.

Between the top plate and the bottom plate, sealing mass is applied. Instead of this mass, a sealing cord could have been used. But to use it, a groove has to be cut in the bottom part, so that the sealing cord as a defined position and thickness.

I'll test the vacuum table with different parts. First, some aluminium stock material is tested with my whole force to move or remove it from the vacuum table while the vacuum pumps are working. It really does work very well and it is quite impossible for me to move or remove the part from the table. Second, one of two stiffeners for my z axis is machined on the vacuum table. A quick demonstration of this is shown in the video.

Thank you very much for your support. It has been a fun project.
