How many Hg should I be pulling for the bridge glue-down? I'm getting about 21" if I just use the vacuum side of my pump and I can manage 23" if I stage it with the pressure side. It does take a bit of time to get from 19 to 23 though. Should I look at getting a new pump?
I'm assuming that whatever the answer for the bridge, a similar answer would go for the top or back bracing....
Thanks.

21 inches of Hg will work, I live at 6500 ft and that's about all I can get. I've never had a bridge fail with titebond or hhg.
Of course a good fit is important.

Can I assume that same pressure will work for bracing?

Yes J. That amount of Hg will work.
