I had already heard about the bladder weight system, so thatís what I was referencing.  

Iím still wondering, if vacuum kilns eliminate drying defects, why is a weight system needed?  Just thinking out load.

Gotcha.  The only reason I can think of for the bladder would be for that lil extra effect on flatter boards.  And when you get a board that is warped going in will be flat coming out.
If you are enjoying what you are doing,  is it still work?

I can see it reducing or eliminating drying gradient stress problems but wood is still shrinking and squirreling around. If you restrain it until it takes a set I think it would help in any kind of drying.

The bladder will exhibit 8 lbs of downforce per square inch.  Personally, Iíd Prefer to not dry my wood without some substantial weight.  A thousand lb. slab thatís 4íx4í will only exert  .43 lbs per square inch.  They will probably offer bladders in multiple sizes such as 8í and 12í lengths  to accommodate the length of your stack.  The downside is that will be sold individually.

I spent Wednesday and Thursday and it seems be be very well attended.  Especially today.  I actually walked 10 miles between the two days

I am trying to understand these vacuum units. I use one up here, (Radial Kiln) but my red oak comes back with stress cracks. 
I like the idea of the ivac unit, complete and ready to go, and with a quick turnaround of product, weather it is mine or a customer. 
I like the idea of being able to schedule customers wood. An in date and an out date. Scheduling would be key..... I can custom cut a log for the customer and have it ready to go in 2 weeks....not 2-3 months

Some defects that are seen after drying are due to issues with the resource and some are due to sawing issues. The kiln will not cure them.  The wood also shrinks so shrinkage defects can occur, like around a knot.

I saw the kiln at IWF.  They are selling like popcorn.  I am impressed about the turn-key kiln.

Took a look at the kiln myself and met Jim. Very nice kiln and super nice guy. Just have a problem with this budget thing.
Two LT70s and to much other support equipment to mention.

Stephen, I think it's probably a radio frequency/ vacuum kiln you're using. I've not been around one but have run rf glue presses. There is a ground plate on one face and basically an antenna plate on the other face. Punch the button and it "broadcasts" fm radio through the moisture in the glueline or the wood. The oscillating wave gets the molecules bouncing around which creates heat. In a vacuum where warm breezes don't blow it's another way to get heat energy into the wood.
On another thread we were talking about lightning strikes. Oak would often peg the machine, I'd have to dial it back and cycle a little longer. Anecdotally it is the most frequently hit tree. We figured oak is the best conductor in wood.

Thanks Don, I understand that. 
with the IDry, is it just using vacuum? Or does generate the heat with another heat source?

Be aware that the cost of a kiln for drying lumber (a piece of equipment) can be depreciated in the US (and Canada?) when filing taxes, even though it might look like a building.  This helps lower the cost of the kiln.  Many banks are interested in funding business investments, but you will likely need a business plan.  County extension offices can often help in developing a plan.

Stephen1,  is the Radial kiln using steam or radio-frequency and vacuum?  Where is it made?  I am not familiar with the name.

It is my understanding it is made in North America, it uses radio frequency and vacuum to dry the wood. I do know he has a large waiting list for his 2 kilns. When ever I have taken wood to him, I wait about 6 weeks to get it in the kiln and then i have it back in under 2 weeks. I am seeing a need for a fast turn around of Kiln Dried wood, mine or another sawyers. i would prefer not to get in the business of running a store.
In this day and age and my location to the big city Of Toronto, full of people that want their wood back yesterday, I do see the need for fast Kiln service and a sharpening service. 
Sawmills are popping up all around me and I think that servicing the Sawyer, Kiln and Sharpening I could have a nice business.  
so because of the way I have been thinking, I am paying attention to the Kiln side of the lumber, I have been doing pretty good on the sawing part, now onto something new.

After much deliberation I finally pulled the trigger on the idry. Very excited about what this is going to do for our business.

Sounds like a long lead time.  Obviously pictures wanted!  Our own build is so slow this would be faster.

Nativewolf, there will definitely be some pics. Not excited about the lead time but what do you do. Vaccutherm is saying about ten weeks. It took about that for woodmizer to get me my mill and Baker just told me they are 6months out for a mill so I guess ten weeks isn't that long.

Looking forward to the pics.  I guess a 10 week wait is also a good sign, they are selling like crazy.

Good for you Busy.  I am leaning that way hard myself!  Can't wait to pick your brain.  I am actually going to the guy who bought the floor model from the IWF here in Atlanta a few weeks ago.  Going to see what he thinks about it.
If you are enjoying what you are doing,  is it still work?

Detailed report requested.  Wood quality, drying time, species he's tried, loading & unloading issues, energy use, heck what type of coffee he drinks :).

I did have a chance to talk to the guy running an Idry.  They love it.  He did notice on some mega wide poplar that there was some cupping.  But nothing but good things to say.  I asked Jim parker about shipping and he said pan on 8 to 10 weeks.  Hope this helps.
