Solar Kiln Build
« on: January 19, 2017, 12:24:06 pm »
I've decided to build a solar kiln and it will be based off of the VT design. I have a large surplus of syp logs so I'll be sawing all of my own building materials. I plan on using board and batten on the interior/exterior walls instead of plywood. Are there any major negative consequences for using board/batten vs plywood? I don't mind using 3/4" plywood for the flooring, just didn't want to spend the extra $ for the 20 sheets of 3/8" plywood for the walls.

Yesterday afternoon, I cut forty six of the eighty two 8' and 10' 2x4's the plans call for...

Hey Deese, welcome to the solar kiln club. The problem with board and batten on the inside is that you'd have a lot of seems to seal. You don't want warm moist air migrating into the insulation. Just my amateur observation. I'm sure someone more qualified will chime in.

I might just buy the plywood for the inside, but not sure yet. Still gotta finish sawing out the 2x4's and 2x8's and get some 14' lumber from another sawmillin' bud of mine (not a FF member) since I currently can only cut up to a 12' board.

We suggest that the interior have a plastic vapor barrier.  With B&B, it is likely that there will be lots of holes in the plastic barrier.  The interior covering is to protect the walls and vapor barrier so cheap plywood is ok.  Usually particle boards, osb and waferboards do not have adhesive and construction that will last in a kiln.  Use plywood with exterior adhesive, like CDx.  A relatively smooth floor is really required, so the interior floor needs to be plywood.

Have you thought about closed cell  (2 or 3 lb) spray foam and then covering with metal siding....closed cell provides a thermal and moisture barrier and no seams and the metal will protect the foam.  More expensive but will retain the heat better and in a more uniform manner

Mr Gene, Thank You for your input. I will do as you say and use plywood for the interior walls and floor.

Woodshax--Yes sir, spray foam insulation did come to mind, but I doubt I will go that route...

DJ--very nice kiln you have sir!

Thanks Darrel!

It seems that sawing more building materials will be put on hold this weekend, as it is going to rain for the next 2 days here. Ugh.

I sawed more 2x's for the kiln build yesterday along with other various pieces of lumber.
 

  

 

The 12' trailer was loaded down. Only had to pull it a couple hundred yards.
 

 

I cut some 3" thick slabs of 16" wide 12' long shortleaf pine. Very clear lumber. Going to let them air dry over the next several months, then dry them in the kiln. I figured they would come in handy for future woodworking projects, whatever they may be...They were HEAVY.
 

  

 

One of my logs had a bad catface. I cut several 2" and 3" thick slabs from this particular log. With a little creativity, I think they could make some interesting tabletop/bench pieces. I would have to set the pitch in these for sure, as they are full of sap.
 

  

  

  

  

  

 

I didn't work alone. I had my sawmill buddy with me.
 

 

I've got access to a small walk-in cooler (appx 8'x8' inside) that isn't used during the Spring/Summer months. I'm hoping to experiment with it along with my solar kiln over the Spring/Summer.

I finally stacked the lumber I cut 9 days ago. I had left it flat stacked on a trailer in the shade. Very little sign of mold. I couldn't have gotten away with that during the summer months. Mainly 2x8's and 2x4's along with some 3"x16"x12' slabs.
Hoping to get started building the frame in a week or two.

With my 15' track, the longest I can currently saw is 12' 2"
I want a longer kiln than that, and I'm not paying $200-$300+ for a bunch of 14'+ lumber.
Instead, I'll spend a tad more and get the 10' track extension.
All I need is a stamp and check will be in the mail tomorrow.
 

 

I see some 22' SYP beams in the near future.
I'm glad my brother has forks on his tractor

Be warned that it is the start of a slippery slope (old saying).

No.     Wait.      You are already on that slippery slope  :D

Looks like your going in the right direction. I use B&B on my exterior walls and used wafer board for the inside...It was laying around in the shop, so I got to use up some scraps.
I also cut all the wood siding and sticks for the frame.
Build the floor super strong, and have fun 8) and welcome aboard!

Look Out! 10' track extension with extra log clamp arrived just a few minutes ago.

 

  

 

Already got it loaded and secured.
 

 

 I've got so much to do it's mind boggling. I need to set more posts and get it attached, but I only have so much spare time...I've got 30+ 12' long syp logs of my own still waiting, and a customer just called this morning and is dropping off 3 trailer loads of mixed pine and hardwood logs. Not sure how big the trailers are or how long he needs his lumber  :o :-X  I will contact him after work to get specifics. I am hoping he wants longer than 12' so that I will be forced to go ahead and get extension attached  :D If not, I will probably proceed with what I have until things slow down a bit.

Got a call from another customer while I was typing the above post. He is searching for a service that I currently cannot provide, so he is being referred to another FF member that I know can suit his needs.
