An interesting read on screw-holding ability (1926)

[Squigie]

I found this interesting: HOLDING POWER OF WOOD SCREWS (United States Department of Commerce, Bureau of Standards, 1926, pdf)

It covers several aspects of screw-holding ability in half a dozen types of wood and reveals some interesting things, like the fact that quality control and adherence to standards weren't great even in 1926.
All in all, the results definitely tip their hat to Hard Maple.

I thought some of you might like to give it a read, as well.
(Maybe that's why I can't carry a conversation in polite company and don't have many friends... )

While we're at it, another study on screw and nail withdrawal resistance: Determination of Screw and Nail Withdrawal Resistance of Some Important Wood Species (2008)
Rather unsurprising conclusion: Oak is better than pine.

Like reading a book on how to care for Passenger Pigeons.

Those woods barely exist anymore, might still be labelled the same but their physical properties are much much weaker unless you're paying 10x what regular lumberyards charge.

Don't buy from lumber yards.
