Feelings on Ash for wide board flooring

[thecfarm]

With all this talk about how ash look I might use it on the wife's veggie shack. I will saw it all 3-4 inches. I have no way to do anything to it besides plane it.

just to get a rise out of someone..   

still wish this log was uncut when i got it.  3 ft and 4 ft.   the 4 ft one is 17 in dia.  took everything me and a buddy had to get it in the truck to get it home.

the cluster of the 3rd stall.    that one cant..is 6 inches thick and 3 ft long.   it will be resawed as soon as i bring a welder here to fix an issue, currently i get about a 75 deg angle not a nice 90 after i 1/4 turn the log ...lol

Now you've got to figure out a nice project for that beauty.   ;D

i havent seen the question on this thread asked...  for flooring and cabinet stock,   should the board be ripped to rough dimensions prior to drying ?

[dboyt]

Ripping can save a little room in the kiln, but drying can reduce the width by as much as 10%, depending on species, type of cut, and whether you rip it green or air dry.  You will also lose some width when you tongue and groove it.  If you rip the boards before drying them, be sure to account for this.  An 8" board on the floor would need to be cut 9" wide on the mill.

I'd take a wide floor with cupped edges any day over that narrow main-stream material. I think the negativity about wide flooring has been propagated by the manufacturers of the other stuff.  :(

I've done quite a few wide floor installs for my own projects and haven't had a single problem with any of them. Proper handling (drying) and installation is key. I always let the material acclimate to the house for at LEAST a week...more if possible. Tongue and groove makes is near impossible for the edges to lift/cup. 

Wide ash will be lovely! Post pix!

This topic is 6 years old but I did indeed use 6" & 8" Ash for flooring in my Cabin Addition

This is an old topic that has been resurected.    Here iis another one I started more recently on ash flooring.   Some of the post have pictures.  ;D   

Ash for flooring in General Woodworking
   

I still haven't started my flooring as we have not yet put on the new addition.   That effort starts in mid April.    I hope to be making flooring by late summer this year.

Years ago, maple flooring up this way was 2", built in the 40's. It's in all the local farm houses of the day and old school house floors where hardwood was put down. The oak and birch stuff you buy now for floors are an 1-1/2" -2" wider.

Ash of course is commonly used for flooring so no issue there.  I can tell you that 12" wide Ash boards from the outside of the log will many times want to cup.  Sometimes you get lucky and it's only slight and you can plane it out, but sometimes it will cup all of a half inch or more.  Manytimes the cup is much worse at one end of the board than the other.  Cut off the worst part, then rip it into two 6 inch wide boards if you think you will be able to plane those flat.  If it's cupped too bad, burn it.

I've never quarter sawn Ash, but I'm sure if you did, on a big enough log, you'd get stable wide boards.  When I flat saw wide boards from the middle third of the log, they are generally pretty stable(they are by default rift and quarter sawn).

You know, could do traditional quarter sawing(as opposed to Reverse Roll Quarter sawing), and end up with some pretty stable stuff and mix widths in your floor.  If you're dead set on all wide, you'll need 27+ inch logs and Reverse Roll them.  That will take you some time, but you'll get more wide boards and they'll be stable.  You may need larger than 27 inch logs in order to remove the pith and the sapwood.

After the rough lumber has been dried and planed it should be dried again in a warm, dry, airy place.  Immediately after the floor is sanded it must be painted with whatever you are using [first coat]  Don't wait until the next day. If the installed floor shrinks anymore it will reverse cup and not be a problem. Ditto on table tops, etc. This tip can make a project successful that otherwise would not have been.

Go wide
Then go thick
My 2000sqft floor was sawed with my old lt25 5/4 red and white oak
Finished board was just over 4/4 some widths up to 10"
Good results but floor is rustic
Some cupping occurred but acceptable for this guy

Possibly get better results by drying wide, then ripping. If you rip to final size, the board will both shrink, and possibly crook (side bend). Then you have to straight line rip the crook out, and end up with an even narrower board. 
And if a wide board does happen to cup badly (more than you can plane out) you can always rip it into a couple of narrower (but but still usable) boards later. 
But with my mill, I saw dimensioned boards anyway. Wider boards are slower and a lot more brainwork, so I would generally just cut 4" or 6" x whatever and straighten them up as needed later.

To me ash is way prettier than red oak and has been my experience that ash has way less moisture in it and therefore does not want to twist, cup, and split hardly at all compared to oak as oak generally is going to air dry to fast and act up.

So, I read through this post. I'm at the beginning of an Ash wood floor project myself. I want to go wide. So, if I want to go 8"-10" wide boards, how thick should I go? Is thicker more stable from cupping/warping? I will be bottom kerfing. Undecided on square edges or shiplap. Not going T&G or Splines. Its a shop floor that I want to be able to pull up boards to replace if they get damaged or too soaked in the inevitable transmission fluid spill....

Also going with sleepers to face nail to. How thick and wide should the sleepers be? Thicker than floor boards? 

[petefrom bearswamp]

Is it on a slab or joists?
Air or kiln dried?
If joists what spacing.
Screwed or nailed.
IMO thicker is better for shop floor to take the abuse and I wouldnt worry about gaps due to shrinkage and some sweep in the boards.
I wouldnt worry about some oil spilling either.
Some old machine shops and factory had purposely oil soaked floors.

Its being screwed to sleepers, not sure on spacing. If I go with 8" wide final boards, I'm shooting for over 1" thick. maybe 5/4 or 6/4 final? 
I am guessing 6/4 rough sawn, then air dry. Plane and rip cuts to final dims of 5/4 x 8" wide, shiplap, kerfed bottoms. I think 12" sleeper spacing is pretty close, so maybe go 16". I might tighten up the spacing under where the four post lift will sit.
Pic below shows from bottom...subsoil, 4" gravel, 1" leveling sand, 1" foam, 1" thick sleepers with foam in between, then final layer of floor boards. Also shown is a perimeter foam board to serve as insulation/water barrier from outside. Only shown 12" deep but should probably go 24". 
So, I really just need help with sizing the floor boards and the sleepers in respect to the moisture content, cupping etc.  I will be milling on an HM126, and air drying in the barn they will find their final resting place in.

I use ash for the floors in my shed kits, I cut it 5/4 and shiplap it, works great in that application but shed floors don`t tend to get too dry.

Nice, so you sell shed kits? That is cool

yep, I sold a few, along with a family giveaway, I came into a *stuff ton of pine logs from blow overs so its a way to move some, also have plenty of ash

Guys, for wide board flooring, a good trick, is to put a screw in the middle, with a wood plug to hide it.
