Now hear this.

You have a 2 1/2 X 2 1/2 piece of 7/8 " wood. Straight grained, and you drill a 1" hole in the center.

If there will be pressure/stress on the upper side of the hole, in which direction [considering the grain] should the pressure/stress be located.

1. Pressure/stress alligned WITH the grain ?

2. Pressure/stress at a RIGHT ANGLE to the grain ?

I thank you for your varied and [posibly] differing opinions.

With the grain. Cross grain will tend to split the wood.

Take a wooden shingle, cedar shake, or a log splinter in your hand. Bending with the gran it will bend a long way before cracking. Across the grain it will separate early on.

look at the end grain quarter sawn or flat sawn?

properties will vary

if you want it strong in all directions, lay it up like plywood with different grain orientation on ajoining plies

In addition to the above, will the stress be parallel to the face or perpendicular to it?
