Some of you may have noticed from the later pictures that the door is too tall for the opening in which it was meant to swing.
The original intention was for the door to swing under the low hanging wall. I measured a good 30mm clearance between what I thought was the top of the door and the bottom of the low hanging wall. I hadn't realised the door was raised by 100mm because it wasn't indicated on the plans.
A perfect combination of assumptions and misinterpretation. Shit happens.
The door was only able to open through an arc of 400mm before it collided with the wall and this meant it would be difficult to transport the material for the next stage of the build into the chamber.
It also had the potential to delay the schedule by 3 weeks because the shielding test couldn't be completed without the door.
Its always better to get the shielding test done before the next stage starts. Can you imagine fitting all the ferrite tiles, absorbers, wiring etc and then do the test only to find out that 1 bolt wasn't tight enough and you missed an EMC gasket

We decided to complete the chamber with the larger door so that Nick could come in test the chamber. The idea was that he could find problems in other areas that we could fix then and there. After the testing, the large door was going to come off and the next stage would start. All the material could now be moved in. The area around the door frame would be left until the last possible minute. This allowed the 2nd stage to stay on track whilst a shorter door and blanking panel were made up and delivered.
The solution was proposed by the chamber installers who are contracted by the company who supply the chamber. They are on track to deliver the new door mid next week and at no charge to my company. All very professionally handled.

Anyway, I arrived back to work the following Monday to this:

2x4 batons were laid along the floor, ceiling and side walls. 10mm plywood was screwed into the batons on the floor. The chamber smelt of fresh sawdust.
