Got the rest of the plenum sealed and surfaced both sides and glued the spoilboard.
The color difference is when I ran out of oil based polyurethane.

It was a lot of work sealing but I happy with the results. I might of been able to get away with one thick coating instead of two.

Applied wood glue

I put the spoilboard on top and turned the vacuum on for about 45min to an hour while the glue set. I then let it dry overnight and surfaced the top the next day.
My spindle is fairly out of alignment compared to my spoilboard before. I did some adjustments but it still needs more (still usable for normal wood projects)
I didn't cut anything yet but with one stage powered on seems to hold down sheet goods pretty good. I'll decide if i'm going to glue the pvc pipes together depending on the results and in/Hg im pulling, however i'm fairly certain I have all the connections pretty tight.
Things to do
- Seal sides of spoilboard
- Install vacuum gauge
- align the spindle better in the xz and yz axis
