Short answer, no.  Where I'm working on it in my garage is a long way to 
its PSU & the rest of the kit in the basement.  I first need to get it 
mounted so as not to short something out, so it will not get powered until 
attached to the bottom of the sandwich.  And that's 15 minutes here, and 15 
minutes there because my garage is also the assembly/finish area for a set 
of 8 storage boxes I am making for the next door neighbor, which will also 
double as seating around their 1/4 acre dining room table.  They are all 
cut out, and I now have the 5th one about glued up & finished.  One, maybe 
two more coats of Sam's recipe, to which I have added a bit of stain, and 
that one will be ready to carry up the hill.  In the meantime the 6th one 
is being glued up slowly.

Yeah, it keeps me out of the bars but this has turned into a bigger project 
than I envisioned, primarily because of the difficulty in making stain work 
on wormy poplar.  Natively, it has extreme color variations & it takes real 
care to stain it so as to override its greenish tint.  Tough, strong wood, 
but the first coat of finish absolutely must be a couple coats of 1 to 2 
pound cut shellac to seal it so stains don't soak into it like a desk 
blotter.  Once that's done, then you can wipe the Sam's on & start tinting 
it till you get roughly the right color.  Sometimes 7 to 10 coats to get it 
right. About 18 hours a coat polymerizing time.  Dry in 3 hours, but not 
hard enough to re-coat till about 18 to 24 hours, so it's a slow process.

Next time I go back to white ash, even if I have to drive to NY to get it.  
My local sawyer only has it in 1" thickness & a tabletop needs more.

Cheers, gene
