Before I could turn this:
Why is there a diapers box in my planer dungeon?
into this:
2/3 of the core slab.
I had to replace these:
I wonder if the old blades are re-sharpenable…
The previous blades got pretty beat up when re-flattening the old planing slab. It turns out that water-based wood filler > carbide blades. But I must have known this day was coming, because I had a spare set of blades.
So after a morning of flattening one face of each board (by hand), then an hour or so of thicknessing (by machine) and smoothing for final glue up (by hand), I had eight boards at a total depth of 10.5″. Exactly half of the total depth on the new workbench.
It’s actually 10 9/16, but who’s counting?
The glue-up was a nightmare, though. Despite some aggressive shaking, the older PVA glue was starting to get viscous and kept clogging in the nozzle. I am hoping the glue holds up, as it was over two years old. It would be a pain to redo the glue-up, but I do own a heat gun if worse comes to worst.
Ordinarily, the sign of a good glue-up is squeeze-out from the knots!
I can add two more boards to the core and still be narrow enough to pass through my thickness planer. Which I will do next weekend.

Your planer blades can be resharpened, but I wouldn’t try to do it yourself. You can unbalance them and give yourself a headache.
PVA glue has a lifespan, if it’s more than a year old – throw it out. There’s a code on the bottle that tells you how old it is: http://www.woodmagazine.com/materials-guide/adhesives/cracking-the-glue-code/

Actually, the article says 2 years for PVA. Sorry. I’ve probably been throwing good glue away, lol. I always thought it was one year.

I called Titebond and heard on the phone it was 2-3 years if kept at room temp. I also heard that if it expired, it will just fail, so maybe I’ll luck out and it won’t have failed.

I worry about such things more than I should, perhaps. I like to err to the side of caution.
