Trying to figure out the board feet need for a shuffle board table. The hard maple will be used on its side instead of the face so I am confused as to how to figure out board feet.

Playing surface is 3” thick 20” wide and 12’8” long
I plan on using 8/4 stock

It is simple math if you know how to do math? I can do it without a calculator, in my head, Kids!!!
Roughly 50+ Brd Ft. 5 brd ft for each 3×13 ft piece, 20w divided by 8/4, 2 inches =10, 10×5brd ft =50
What the freck they teach in school now a days????

The calculation is the same. Board foot is a unit of volume not area. 12”x 12” x 1” = 144 cubic inches = one board foot.

In your case 3×20x152= 9120/ 144= 63.333 board feet, after being milled.

8/4 stock is 2” thick

12’ = 144” + 8” = 152” long

3×20 x 152 = 9120 / 144 = 63.33 bft.

I think… :)

So, you are going to rip everything into 3”+ strips… plane, etc. & glue them together to get 2 slabs 10” wide, then glue them together to get 20”??

Sounds like FUN!

Actually a bit less 3 divided by 12 is 4brd ft but I a lotted for 13ft and checked ends and scrap.

The 8/4 stock will need to be milled, lets say you get 1 3/4 of finished stock from each board. That means each 3” wide strip is 5.54 board feet ( 3”x 152” x 1 3/4”).

Everything depends on the amount of usable material each board you buy yields. If you buy 6” wide boards then you can not get 2 3” pieces unless you are willing to change the thickness. If you buy 8” boards there will be waste after you cut two strips from it.

My mistake on my calculation, yes 8/4 yields 1 3/4”’ not 2”’

BDFT is calculated AS IF things were really 1, 2, 3, 4, etc. 4//4 = 1… 8/4 = 2 for BDFT calculations…

Building wise, figure the real dimensions… not the make believe ones… LOL Right?

If you rip’em using a band saw, you will not wast 1/8” per cut… You must figure kerf size and get the boards wide enough to give you the least amount of waste. If using a 1//8” kerf, figure 1/4 for cleanup,,, so 3.25” strips is what you should figure on… 6.5”(2), 9.75(3), 13”(4) widths…

Kirf, if you the right rip blade you may not need any clean up, if not, a 32nd to 16th at most, if you need a 1/4 a Beaver must be doing your ripping

If with the right blade and tension, and a good fence and set up for drift.

At 13’ long it comes out to 65bf.
I keep a board foot calculator on my phone. Free download from the play store.
Yes simple math. Simple calculator too, and I make less math mistakes that cost me money.
Good luck.
