I dug holes for piers for my drying shed.  I'm calling it a drying shed for now and not a kiln.  It will be a 10 x 16 shed with a dehumidifier.  I will air dry lumber to at least 20%before it goes in the shed.  Tomorrow I will have treated floor joists, joist hangers, concrete blocks and bags of concrete delivered.  I love having a small town lumber yard.  They will deliver and bill me.  Great thing these days.  I plan to have a picture of something to post tomorrow.

If it is piece of equipment, like a kiln is, you can take a tax depreciation deduction.  So, make sure you call it by it's correct name...a humidity controlled lumber holding chamber.

You might want to add plastic sheet vapor barriers to the ceiling (prevent drips) and walls.  Grade the soil outside so water flows away from the chamber.

Thanks, good point Gene.  I will claim the expense of building it as a business expense.  I like the title.

I like that, I guess that makes me a humidity controlled lumber holding chamber technician. Makes me sound smarter than I am.   :D

For permitting purposes, ag exemption, my sawmill shop is a silvicultural support building.

My supplies didn't get delivered until about 2.  Got most of the work done for the foundation.  I'm using concrete blocks filled with concrete.  Tomorrow I will put two more sets of concrete blocks for piers on the long sides.  I ordered 10' 2x10s for joists.  They sent 12'o now I'm considering using them, but they will have to be cantilevered.  Not sure that's a good idea.  I need 7 more bags of 80lb concrete tomorrow.  I need to figure out how I'm going to insulate the floor.

On my solar kiln, built the floor, put the bottom on the joists, then rolled it over with the forks on the skidsteer.  Yours is bigger, so might be more difficult.  Bet you can do it though.
Most everything I enjoy doing turns out to be work

firefighter ontheside

I've seen where folks have done that, but I don't think that's gonna be possible with a 10x16 deck made with 2x10s.  I'll probably nail on cleats all the way around each joist space and lay in pieces of plywood or perhaps corrugated plastic.

a cantilever of 1 foot over each side, is not a big deal since in a kiln, most of the weight is in the center, and the outside is for air flow.  but did you plan to have a beam along the long sides to set the joists on?  or may need more lumber if you had prev. planed just a rim joist.  neat idea.  more bang for he buck.  Gene seemed to think fiberglass was fine for insulation.

I will be doubling 2x10x16's for the beams.  Joists will hang from these on hangers.  What I may need to do is double any joists that will be sitting on the piers, since the double 2x10 will now be hanging from the joists.  Good point about the weight.  This would actually put the weight more over the piers instead of hanging inside.  I think you just convinced me.

You're about to create a bear. The hangers on the doubled rim to doubled canti joist connection would need to be flipped upside down for the rim to carry the common joists load, think about your load path(s).

doc henderson

Don can he incorporate a beam into the floor frame.  maybe just inside the joists that are on the piers.  he appears to have a lot of purchase there.  otherwise would need to extend out and under the rim joist and that would gain height.  I doubt he wants it any taller.  I guess the issue is how to fasten it.  @Don P

Basically its a machine that takes a pounding rather than a deck that you sip tea on. Don't cantilever, use the cutoffs for blocking and keep the joist spans shorter and the load paths straight down to solid bearings. My gut says that double rim is already sketchy for the load.

firefighter ontheside

I had already thought about having to turn some hangers upside down.  10' was already plenty big for what I want to do and 2 more feet would just add more cost to everything else.  I will go ahead and keep it 10'.  The double rim will be spanning 6' at most as there will be a mid point pier on each long side near where you see more blocks sitting.  The corners are 24" in both directions.  Thanks for the advice guys.

as you are building, can we at least get a pic of you "sipping tea"  on the deck?!  :D :D :D.  great job so far, it should stand for many years.

Progress today.  Got the last piers done.  Put all the joists up and one of the double band boards up.  Tomorrow I will double the other one and then put all the joist hangers on.  I need to put posts down to the mid point piers.  Even without them, this thing is stout.  Here's a pic with my "iced tea".  Really it's an empty water cup.

looks fantastic!  I do not see your pinky finger extended... you know to drink your tea, Sir Firefighter on the Side!   ;) :) smiley_beertoast

Thanks Doc.  I have a lot of work still to do, but just happy to finally be moving forward with it.  I really need to get some wood in there.  Getting wood in there makes room for me to saw and stack more.

Not much visible progress today.  I put all the nails and screws in the joist hangers today and hung the doubles for the rim joists.  Squared the deck and installed the middle point posts.  Next time i will insulate the deck and hopefully get the plywood floor on.  I'm only putting r13 in the floor since that's all that will be in the walls.  Ceiling will probably be r19, but maybe 30.  I'm thinking of just a sloped ceiling/roof instead of having an attic space.  Hoping to find some used metal roofing when the time comes.

Because a kiln has fans, so the air is stirred up well, extra insulation on the roof is not necessary.  It does not hurt, except the pocket book.

That makes perfect sense.  My humidity controlled lumber holding chamber will have fans.  Makes sense that there's not much point in insulating higher in one area than in another.  Thanks, Gene.

What about doors?  I'm considering just a 36" exterior door at each end.  Will 36" be too narrow.  Most of the time it'll just be me carrying wood in and out.  Widest thing would be about 25".  It is an LT15 after all.  But then I'm thinking I may want wider, like French doors or make my own door that is more like 48".  So many decisions to make.

how about a man door at one end, and an insulated garage door at the other?  just hate to see you have to carry each board in and out for the next 20 years!
