We are building a log cabin in Uganda. There are a lot of Eucalyptus plantations around, so we hoped to use these to build with. We can get around 13inch diameter trees, but because of the climate being tropical the trees grow very fast, these are only 8 to 10 years old. If we sealed the ends, treated the logs very soon after felling and kept them covered out of the sun for a while do you think it would be ok?
