I-Channel CNC Egyptian plasma

**Islam** · 02-07-2012, 04:12 PM

Hi all,
Till now nobody knows clearly how ancient Egyptians could engrave their alphabetic and drawings on their temples walls and obelisk by such accuracy.
Also me don’t know, however I think that my grandparents had invented a special router - not necessarily to be cnc - which had been used for their engravings on the very hard rocks.

My name is Islam from Cairo, after I have been lurking in this forum for some months, gathering information and working on parts lists, I put my first design and laser cut parts drawing of my cnc plasma cutting machine by using the sheet metal Autodesk inventor and started the implementation of my project.

My design is based on the (I) channel as the gantry rail without need to use linear bearing or gauge plate taking into account the precision conservation as we shall see together.
Water table will be a standalone table carrying a standalone water tank.
The machine designed to be able to be dismantled into parts and pieces which are easy to be carried by man ,delivered in a small truck and installed in any place without need a fork lift or a wide door.

Firstly I would like to thank in advance cnc zone for providing such a wonderful resource.

Hers my progress so far, comments and suggestions will be appreciated.

The chasis progress.
I used a flat board, DIY right iron welded angles and G & F clamps to get an accurate and precise chasis as illustrated in the photos.

These are the photos of the leser cut parts of my DXF design.
