I've got a pair of wooden gates across my drive. The frames are OK, but the planks on them are very prone to swelling and contracting. In the summer they contract to the point where the wood started to split, and in the winter (about now), they swell to the point where they jam, so I'm unable to open them. Is there an easy solution to this, or am I either going to have to live with it, or replank them with some different timber ?
TIA
