I Have Regressed

The build of the distlation tank and engine is coming a long. Although the engine has been completed the distlation tank still needs a few details:

1. Steps up to the tank platform
2. A wooden ladder up to the top of the tank
3. Two feeder pipes from the top (I need to drill a couple of wholes on the top of the tank)
4. Door for underneath platform

Most of these components have been completed and are wating to be added in.
