Quote from: forrestM on June 21, 2021, 06:36:39 PMAlso, for a house with wood heat, and minimal air conditioning, what should my final mc be for Virginia? My plan was to take it down to final mc, remove from the kiln, straighten to 5 1/2 inches, and take to my friend for tongue and groove and then install.

If your heating with a woodstove 24/7 I would be concerned about the significant cracks that will develop in 5 1/2" wide strips.  With minimal AC I can see the MC going from 9+ summer to 6 late winter.

There is basically only one insect that gets into DRY pine...the old house borer...and it does not cause extensive damage and seldom is able to reproduce.  All other insects need wetter wood.  This is for the US and Canada.  Of course, we get the carpenter bees, but sterilization is not a solution...same with termites.

Now, if we have ambrosia beetles and the wood is used in a wetter location, even with sterilization, insects can be expected.  This is why we use pressure treatment in wet locations and for ground contact.  Borates can be used when water will not leach out the chemical.  Getting borate deep into the wood can be an issue.in other words, borate treatment is often a multi day procedure.  Plus retrying after treatment may be necessary.

Bottom line is that sterilization for softwoods is not effective for protection of the wood used in wet locations.  Chemical methods, usually PROPER pressure treatment, will provide thirty years of protection or more.

I use heat as a means to routinely kill anything that has taken up homesteading in my air dried wood stacks and pallets. 

As Gene mentions, carpenter bees are very bad here until late summer, and they will bore into anything they can, even old pressure treated wood.  I have 8 traps hanging around my barn and they fill up. 

The bottom of my kiln is littered with all kinds of after air drying creepy crawlies, and includes hundreds of carpenter bees hidden in the wood and pallets, scorpions, mud dobbers, wasps of several species, hornets, black widows, mice, snakes, etc.

There is nothing worse than unstacking a pile of air dried stickered wood and having a scorpion crawl out and land on your foot, or bunch of hornets come boiling out at you.  So I heat sterilize everything, not matter what is is, take it out of the kiln, dead stack it immediately, and put it in stasis in the main building.

Setting the pitch in pine serves the same purpose.  It also simplifies the questions I get asked all the time from "green minded" customers.

Question #1:  "Is it kiln dried?"  Me: "Yes"
Question #2:  "Have any chemicals of any kind touched the wood? Has it been sprayed or treated?"    Me: "No"
Question #3:  "Has is been sterilized?  Is everything dead in it?"    Me: "Yes"
Question #4:  "How much does it cost?"  Me: "Not too much, let's load you up." :D

If it won't roll, its not a log; it's still a tree.  Sawmills cut logs, not trees.

@GeneWengert-WoodDoc 

Just to clarify, sterilization will kill active insects - including termites. It just isn't necessary for dry pine, and won't prevent further infestation from the pine borer you mentioned, termites in wet locations, or carpenter bees. 

Thanks!

here's how it turned out! the yellow pine is on the floor, 5" x 3/4" tongue and groove. the walls are white pine with a shiplap. The floor has a water-based polyurethane on it. 

everything was between 9-10 percent MC when machined and installed. So far, it looks good.

thank you!
