RE: How I built a wood kiln out of a 20' shipping container
Another serious bit of kit added to your collection. My local timber yard uses a shipping container with radiators. No where near as nice as that though. I thought green oak needed air drying first? How did the timber turn out with quick drying, Did it split at all?
Whether it is hard wood or soft wood, you can dry it all freshly sawed. Having said that it will cost more for time in the kiln since air dried lumber in the kiln will take less time to dry. The soft wood that I put into the kiln had the ends coated with anchor seal, as your probably know, this is a wax paint that keeps the moisture from escaping to fast from the end grain. The wood had also been sitting out for about 1 year. The load came out great with little to no end splitting.
That makes sense. Any checking on the medullary rays? I am asking because I have very little experience with drying timber and get it ready kilned.
There are some checks depending on the board and way it was sawn. Using anchore seal does not guarantee no checking, it just helps in prevention. All lumber is cut an extra 6" on each end so that any checking should it occur can be removed.
Good to know and the 6" extra makes sense.. I would like to kiln my own in the future because I can source the log and get it sawn the way I want. I have clients with windfall tree that want me to make a really personal piece but at the moment that is really difficult. Thanks for you advise
