The first thing I do is check the log with a metal detector. If Anything shows metal you are wasting your time because nobody is going to want to saw it. Had this happen myself with 2) 3' dia 10' long maple logs from my homeolace. Allot of work getting them down & to the mill & then having to take them back to the woods to rot.....
I seal the log ends as soon as I cut them with a sealer, then when I have them sawed I reseal the ends again & also seal any knots or exposed end grains at knots or grain changes, this prevents checking & splitting.
Then I buy firring strips at the lumber yard by the bundle (As it takes ALOT of them) & cut them in lengths to match the widest plank, startin with one stick on the very end & putting a stick spaced every 1' down the length of the plank to the end & one on the very end however it comes out, if it is not exactly to the foot. This gives the wood air space to let it dry out. Lay the plank on the sticks then lay a set of sticks over this plank directly above the last set of sticks & insure the sticks are in line with the bottom stocks so the support stays on the sticks. I spray each plank of wood with a termite spray just to be safe & not have any bugs show up. Repeat til I have them all stacked & sprayed. Then I lay a sit solid concrete 4"x8"x16" on the top plank over each stick to hold weight on it. (A 10' plank gets 11 blocks) I let them sit 1 year per inch in a dry climate & this is usually long enough to dry them & I check them with a moisture meter before using them.
I also stack mine close to a wall where I can tie the stack with ropes to the wall to prevent anyone from leaning on them & possibly turning them over as they are usually unstable stacked this way unless you have rows of 2-3 boards that are all the same thickness & length. If they are the same, they are much more stable as you can cut the firring strips longer & get 2-3 boards with each stick & this helps stabilize the pile..
I have cut & dried lumber this way for 35 years & have had no problems with doing it this way. Nothing fancy or pretty, just stacked & dried. Never have had any bugs in them however I still respray the stack all over about every 2 years.
I can't remember the name of the stuff I use to seal the logs. It comes in a 5 gallon can & you just mop it on or pour some of it into a large dishpan & dip the end of the plank in it & seal the exposed knots or end grain with a paint brush & slop it on heavily. Most saw mills can tell ya what it is called & may have some on hand, but it is not real expensive & well worth the investment as it seals them well. Years ago I used oil based paint to seal the ends & would do 2-3 applications, but it doesn't seal nearly as well as the log sealer stuff does. The paint will dry & crack & the log sealer stays pliable & does a much better job.
