Cypress drying schedule

[Joey Grimes]

I have some 8/4 cypress to dry in my l53 does anyone know a drying schedule I'm assuming the schedule would be similar to pine but I'm not sure and if it's like pine am I limited to 300 bf per load ? 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

It can be dried, fresh sawn, but it takes more energy ( $'s ), and time.

Kiln schedule 257 in DRY KILN SCHEDULES FOR COMMERCIAL WOODS, and then do the modification for a DH unit.  OK?

So if I understand correctly I use the higher temperature schedules emc to modify for my low temp dh kiln .so for over 50%mc my dB 90 wb 86 ?

I used cypress on my mill. I know kiln dried lumber isn't necessary for board and batten siding but I wanted it dried. So I sent my cypress to a close friend to have it dried in a Nyle L200. I had the lumber on sticks for about 60 days and made out fine. We sawed about 6,000 bf and have

  

   a lot more to cut, what a great wood.

Yes, The same MC ranges and the same EMC.  You could use the same RH.

Kiln operators here will not accept Cypress until it has air dried for at least 6 months.  I have not found Sinker Cypress to be any wetter than fresh sawn.

[Joey Grimes]

From what I've heard it's not that sinker cyp is any wetter it's that it has wet pockets that do not release moisture as fast as most of the wood

[Den Socling]

The wet pockets don't want to release water period. I'm re-drying some that a vac kiln customer doing custom drying had up to 160 degrees in a vacuum and the 16/4 Sinker Cypress still had wet pockets. But I have a way. It is really hard to get a uniform 7%!
