We are now part way through a big project making benches and other bits and pieces for a municipal park in Suffolk. Part of this is some marker posts which will run alongside pathways. We are making these out of split oak logs.
Splitting the oak is a great job. You start at one end, bashing in steel wedges with a sledge hammer.
And work your way along. We find we can split a big log like this with just three wedges. As you put the third one in, the first one becomes loose enough to pull out. For such a strong timber, it splits remarkably easily when it’s green.
And here it is in two bits. The black stains are caused by the interaction of the steel wedges and the tannic acid in the oak. You can see exactly where we placed the wedges!
Next time I’ll show you how we clean up the oak and turn them into lovely tactile posts.
