Portable Saw Milling

[MarkV]

Wow, lots of good advice so far. Thanks. I’ve been cruising around the web on some sites that deal with milling and it sounds like .40 cents per board foot is on the high side from what I can see. The guy I am talking to uses a Lucas Mill which is a circular saw mill. I think this limits his cuts to an 8” width. My thoughts were to use the lumber on/in the barn project as siding and 2x4 framing lumber. A rough sawn lumber would be fine for the look we want. May also have a few beams cut for another project. The state forester estimated the stand of trees to be about 45 years old and considered them lumber quality. Other than that I have no idea how to guess what they would yield or their quality. Thanks for the idea of checking the local rate for rough sawn green pine. I don’t think I would go through the effort to save .10 or .20 cents a foot.

I understand the lumber needs to be stacked, stickled and dried before use. How long are we talking for 2x framing material and ¾” siding material? Someone told me to nail up the siding green to help prevent twisting. I would not be anywhere near ready for that yet. Also I was told that with pine it needed to be milled with in a week of felling the tree to prevent stains. Anyone know for sure?

Here are pictures of a cabin I built on my farm. The logs for the exterior walls are 6X7 and were sawed by guy with a Woodmizer portable bandmill. He also sawed 1 bys which I used on the interior partition walls. I utilized about 80 pine trees which were planted by my grandfather back in the day. The guy who did the sawing was a very nice gentleman and he only charged me $1500.00 for the entire project. I have been told that was a steal. Anyway, the cabin is my weekend getaway. I completed the project about 4 years ago and have spent many a fun weekend in it.

Beautiful cabin! Love the interior. I wanted to go with logs for my cabin, but I was intimidated by the labor involved. I went stick built and I'll probably regret it my whole life, although I'll finish the cabin sooner.

i felled my pines in the late fall and they weren't milled until the next spring and there were no stains. Keep it off the ground.
if you nail up siding when its green then the out facing side will dry faster then the in facing side and it will cup. you need to sticker and cover it for a few months. If you are going to put a finish on it then you should seal both sides.
I had mine milled to 1x8's and i nailed them up with stainless steel ring shanked nails. It board and batten. The siding on the sunny side of the house gets the most abuse from nature.

GOOD MORNING,
The circular mill probably has an 1/4 kerf blade,where a band usually will be an 1/8th.Most operations convert to band because you can gain an extra board or two on a log,and make a little less waste[sawdust]
How long it takes pine to dry depends on the drying conditions.If your area is wet,or damp it will take longer,and a greater chance of stain setting in.It also depends on your"drying season"Up here in MAINE late APRIL to AUGUST is the best,The sun is the hottest on the surface believe it or not in APRIL,MAY and there isnt any dew falling at night.At our mill ive seen white pine[1inch] dry in 4 weeks ,down to 15% in MAY[with no rain of course].Starting in AUGUST everything must go in the kilns,because it takes to long.
If your gonna use it rough,i wouldnt bother to dry it on the rafters,if its white pine[that dont usually twist] Red pine ,and southern yellow ,usually will.
Just remember ,lumber is gonna shrink if used green,so on that siding youll end up with large gaps between the boards.The wider the board ,the more it will shrink.Its just a barn,so that may be ok,or you can add a batten strip at a later time.
The stain in pine are actually a living micro organism,according to the inspectors who certify us to inspect lumber,from the NORTH EASTERN LUMBER ASSOCIATION or NELMA .Most large scale mills like ours have a dip tank,with chemicals to kill these organisms before they get started.We dip whole stacks of lumber after the sawing and sticking process.If logs sit to long STAIN will set in too.This is one reason you see larger mills watering excess logs,so dont wait to long after you saw them,if you are lookin for finish quality.
As A Planer man for 22 years I can tell you if you want finish Quality,pine must be down to at least 15% moisture content ,for the best finish.Green or wet wood causes raised grain, tear out,and a fuzzy finish,even with the sharpest of knives.You can run it green right off the saw,if its just to SIZE IT and thats fine if your not trying to get finish quality.Also remember again if you shiplap it or tounge and groove it,its gonna shrink apart if its green.If you try to dry it after you plane it green,you will find it all wont dry down to the same size.The sap wood will shrink different then the heart wood.If you are gonna just surface one face and no edges and add a batten strip for your siding,you will be ok,just expect sticker stain,if you stick it after.It takes longer to dry under the stickers therefor stain can set in.
GOOD LUCK AND TAKE PICS OF THE MILLING ,AND THE BARN RAISING

MARK V,HERES SOME ADVICE FROM A MILL RAT,
Try to find out before you hire a porta mill,if the person is worth beans as a sawyer.Although rough lumber isnt perfectly sized,its a pain in the butt to use ,if the sizing is way off.
alan

Just to add to what Alan has allready stated. If the size is off it can definitely be a pain. Many of my wood working projects require 3/4" thickness finished. If the rough boards are milled to 7/8" and warp while drying, youve got big problems tryin to finish them to size ! Id rather joint and plane an extra 1/16" than have scrap ! Jst an example of what Alans' sayin .

Alan, the lucas mill utilises a thin kerf blade on a motor, the saw head moves back and forth just like on the band saw. It supposedly has less waver than a band though, and especially in knotty wood. .40$/ft would be high around here, but that can vary by region. According to the web site he should be able to cut ut to 16 inches by cutting from 2 sides.

How tall and how big in diameter are your trees?

Stain isn't as much of an issue in the cooler months up here; once again though I'm not sure about your region. At any rate it won't affect the structural quality. (I've also heard of people who make nice gun cabinets out of stained wood.)

I second going to the forestryforum which I frequent a lot too. there you will get every thing you need answered as well as probably the ability to get in contact with a few other guys in you're area who have sawmills and or do this for different rates...

sounds like you may have some useable lumber there... it is better ti give it away rather than simply cutting & burning if possable. this happens more than most people think, small lots or a few trees needing cleared are all over the area I live in and people are hapy to get them removed and have them USED rather than simply haveing to push into piles & burnt... which not only time consumeing is slightly wastefull on top of being unneeded.

i think if someone made a bandsaw mill that could run off a tractor pto there would be a lot of customers for it. i guess the log would have to be moved through the blade instead of the other way around.
