Maybe my A D D is kicking in now. Our process starts out with green logs on stacking sticks to let air go through them. They remain outside, on sticks, for months.
After 6 months we call them PAD or partially air dried. Then, sometime after a year or two at the most, they are moved to a shed under roof. These are referred to as "air stacked" or Partially Air Dried. The only way to uniformly dry lumber to the core homogenize it is with very high heat. You literally cook it in a temperature kiln. Although kiln-dried cypress dimensional lumber is readily available, heat tends to damage cypress timbers too much, so we don't do that.
We are then not selling moisture content directly, but time on sticks as in being air dried. Do you check moisture on the ends? One foot from the ends? One inch from the outside? Two to three inches down? Defects show up in logs as they dry. If we plane a load of green logs what most of the competition sells , there will be almost no defects. These are logs that would have been in your house had they not been dried first.
However, on average, green logs with a complete settling allowance will give you a good house down the road. Send this topic Print. Pages: [ 1 ] Go Down. Author Topic: Cypress drying schedule Read times. It is not sinker cypress. I was just getting ready to write that you should forget a DH kiln if it was sinker cypress.
The wet pockets in that stuff are worse than any I have ever seen. Unfortunately, I can't help you. I have never dried Cypress that wasn't infected. Not sure on the schedule but it has to be air dried for about 6 months before thinking about drying. I have had about 5mbf dried and he insists it be stickers for 6 months first Thanks Buck.

The lumber has a tendency to develop surface checks and end checks. Gene Wengert. What is the difference between rough sawn and smooth planed lumber? Rough lumber refers to the texture of the lumber as it comes directly off the saw blade. Planed lumber can be S1S, surfaced on one side only, S2S, surfaced on 2 sides, S3S surfaced on 3 sides, and S4S surfaced on all four sides of the lumber.
How many different types of cypress do we have in the U. There is one species grown in the United States, scientific name Taxodium Distichtim, Bald Cypress is the most common name. It is know by other marketing names as red cypress, tidewater cypress, coastal cypress, gulf cypress, pond cypress, white cypress, yellow cypress. How does cypress compare to pine? Cypress grows much slower than pine, which is a faster growing tree in its natural setting.
The growth rings in cypress tend to be much tighter, which can improve the energy efficiency of the log compared to other species. Cypress by nature is a very stable and durable wood.
