Whenever I have an offcut of straight-grained clear oak that’s at least 5 inches long, I save it. That’s pin stock and you can never have too much of it around. I like to split it out ahead of time, and lay them around the shop in various corners to let them dry out.
the pins are the most demanding stock in joined furniture, when it comes to moisture content. They should be the driest stuff around. Dry dry dry.
Here, the kids are splitting out some green oak for pin blanks. A cleaver and a rawhide mallet are excellent for this task. Any wiggle in the grain, chuck it. ANY. It has to be straight-grained.
I aim for spliting them them down to about squares about 3/8” to 1/2” thick. Then toss them aside in the shop & forget about them. I probably have 200 of these around most of the time…I tend to keep the oldest, i.e. the driest, in one spot under the window near the bench. when that stash gets low, I scrounge around the shop, looking for pin stock that’s covered in dust and clacks loudly when I knock them together. That should mean they’re dry enough to move into the favored spot in the rotation.
