How many sqft of flooring can I get out of these logs?

[Tim Einwalter]

I’m working on a cabin project and we’ll be machining our own flooring. I harvested a pair of ash logs yesterday and I’m wondering how much flooring I’ll be able to get out of them.

log specifications
#1 11’ long, 12-18” diameter (lots of taper to this one)
#2 15’-6” long, 21-22” diameter

Sawmill blade kerf is 1/4”
RS board size is 5/4x6
installed area: 420 sqft

Is 20% adequate for waste?

are you going to place a sub-floor in? if so normal tongue and groove flooring is 3/4 inch so you can make the logs go further if milled thinner, and 20 percent should be ok if the logs are good on the inside and no unexpected faults. Ash has some quality's of oak nice and strong. how far what you have will go I do not have a clue. I would saw it see what you got and go from there ,the ash beetles are working on ash so logs might be easier to get in some areas infected.

I should say please do not move non-milled infected logs into a area that is clean of the bugs. Although I have heard it is just a matter of time they will be gone, lets hope they are wrong.

I found this chart https://wunderwoods.files.wordpress....nderwoods1.jpg and then multiplied by .8 to account for my need for 5/4 stock. 271 bdft + 44 bdft = 315 bdft x.8 = 252 sqft. Shows that I'm still short, but with what I already have on hand, I'll have just enough for the project.
