Looking like a nice enclosure there - one slight suggestion though.
It might be worth making the cage around the CHE a little deeper so there is more of a gap between the bottom of the element and the bottom of the gaurd.
It's just a precaution thing really but try holding your hand up to the bottom of the mesh and see how hot it is. I try and give mine about a 2" clearance all round to prevent little flickering tongue's doing something dumber than usual.
What are you using for a cool end hide? I toyed with the idea of making large hides out of concrete once but don't have the skill.![]()
**edit**
I just looked at the bulb holder for the CHE - what's that made of? Even with a good dimming thermostat you really should use ceramic holders or metal at the very least as the plastic ones either flat out melt and burn or become brittle and disintegrate eventually.
