Ready for the big pour

May 29, 2010

I built a platform to support the cement mixer and bought 25 bags on concrete.



The table is loaded with rebar and has angle iron on the edge….



…and laid in a space so MDF board can be mounted to the bench. Note the floating 2×4 in the back, that will be a depression in the concrete to holds pencils, etc.

Building form for concrete workbench

May 24, 2010

This is the makings of a concrete workbench. I made a recent addition to the wall behind the frame which are two 4×8 foot 16gauge steel sheets. The form is A LOT of 2x4s and plywood – this was built with an excess of wood to support the unbelievable amount of concrete that is going into the bench top. The bench will be 5 and half inches thick. A lot of rebar will be going into it so I can really pound on the thing.

….but this component pretty much completes the laser cutting system. Its the motor speed control for the ventilation. I can now draw off all the fumes and oxygen generated when the laser is cutting.

Basically, the system is now fully functional.
