Hi Tom,
In regards to the lid; I cut a piece of hardboard to fit, sprayed the lid with expanding foam put the hardboard on and clamped the whole mess overnight. trimmed of the squeeze out with a razor blade. Marked & drilled the 3 inch hole & the mounting holes. The DD comes with a rubber gasket which goes between the DD & the top of the systainer.
If I were to do another, I think I would get some of that dense insulation board that's covered with foil, press it on the lid & then slit it with a knife where the ribs in the lid mark the foil. I think you could then press it into the lid and cover it with hardboard or whatever if you needed to. I think this would be easier to do and just as or even more effective.
The liner is just some scraps of ply I had in the bin with some foam tape along the top edge to seal against the hardboard in the lid.
The lid MUST seal against the hardboard so no air can be sucked in outside of the liner or it won't work properly (and you may break the systainer)
When I can get back to the shop I'll try to remember to take some more photos, maybe this weekend if I'm lucky.
