This is entirely the method shown by Roy Underhill but with color pictures and timbers which he has probably never worked with.
What is a glut?
A glut is a wooden wedge used to split timbers green from the woods.
Made from wood, to split wood! Made entirely with a handsaw and an axe.
Start with about a 2’ section of log 4-5” in diameter. This is my SUV carrying it back from the woods.
Here I am use Australian Blackwood. I have about 50 of these dead standing ones which died in a cold snap about 15-20 years ago when they were less protected than they are now ( Pine trees have grown up around them). Most are still standing, this one fell over but still hard as a rock after all those years – a beautiful grain and color too! This particular piece may not have been the best, but I had nothing to lose to try.
Chop a wedge on both sides of the log using a hatchet or small broadaxe:
Couldn’t resist to plane it a bit to see the color of the grain
Sharpen the other end as well. Keep the length so that it is easier to handle
Cut it into two pieces down the middle
And then trim the other end down to the heartwood and to keep the glut from splitting and done.
Btw, you can’t start the split with these wedges, you still some sort of iron, an iron glut or a splitting wedge but they can be used to continue to split once started. Probably having more than two would be even handier and I might make more later.
As some have suggested, these can be made onsite with a chainsaw too, it’s just that I don’t usually get out my chainsaw for such small pieces of wood.
