Building a Kiln Chamber

[Neil_B]

Bizie, If you leave it on the skids you can classify it as portable and won't need a building permit

 I just can't decide where to put this thing I want it close to the mill but there's not enough room with all the logging trucks coming and going. I think what I'll do is do what I always do when I have a tough matter to decide on, I will ask my little boy.

 Building permit??? What's a building permit.
 Oh yeah that's one of those things that I should've obtained when I built the workshop, the deck, the saw shed, the addition that I put on the house, the deck and carport on the parents house.
 It will look real good explaining to the bylaw officer about not having permits when I own a construction company and pull permits all the time.

bizie, bizie, bizie. Didn't you know? Just remember that when you get a raise in your property tax that you don't ask for a re-assessment . A friend down the road from me had mentioned not getting a permit for his workshop, and a few sheds and a few minutes later were talking about taxes and he thought about getting re assessed. Mentioned it may be a good idea to just pay the tax

Why worry about log trucks when you can just pull it out of their way

A couple of clarifications on the Nyle L200 Dry Kiln:

The drying capacity of the unit varies with the allowable drying rate of the species being dried.  The unit can handle up to 4000 bf of a green, slow drying species such as red oak(max MC loss/day of 3.8%).  On a species such as black spruce (max MC loss/day of 20%) the load would be limited to about 1000 bf.  

It is recommended that additional fans be installed in chambers over 17' in length.

The refrigeration system is not designed to operate at temperatures over 120 degrees F.  Pitch can be set in pine by first drying the load to the target MC and then shutting off the compressor prior to turning the heat up to 160.  

Please feel free to contact me with any additional questions

Hello, Joe and welcome to the forum!

I was thinking of enlarging my soon-to-be-built chamber to handle the occasional 20' boards.  I thought I could limit the capacity for shorter loads  (usually 16'-17') by employing baffles.  I have two fans that came with the kiln.  Should I add a third fan and if so, should I run it all the time or only when drying the longer wood?  I will be drying red and white oak, ash, maple and beech mostly.

If you want to dry 20' lumber you need an additional fan.  The base unit was set up for 16' lumber.  I would wire the additional fan to a remote switch rather than the controller so that it could be shut off when drying shorter lengths.  You have the right idea w/the baffles.

It's been awhile but the kiln is finally ready to go.The last thing to do was seal the doors,and I had a retired carpenter help me do it properly.

I'm loading about 1800 bf of 1x8 D fir that will be flooring.I got the lumber from another mill on a trade for less that I could mill it.It is random length from 10' - 20' and am cutting it on a chop saw at 12 & 14' lengths,and trimming both ends so there is no grit that might screw up the planer.











I used backlight on some pics because the chamber is black,but it has alot of glare.



A shot of the fan,and fan truss.





We put aluminum around the doors with stainless steel nails to cover the joints between the plywood and the 1" foam insulation.It was gooped well with tar before getting slapped into place.The doors and walls are 8" thick.

Will post a few more later.
