(the shorter pieces will fall into line and have improved trim allowances)
We won't likely be able to buy a board that's 48" wide, so we'll buy a board that's narrower, but is long enough to contain 7" long parts that total 48" of width. I believe a defect free board - that's nominally 6" wide (actually 5 1/2") and 10 feet long will do the trick. (remember - we will only be able to use 5 inches of that width. Saw kerf will take the rest.)
That comes to a board that is nominally 1"X6"X10ft. (We should probably buy one 12 ft long just for kicks) This amounts to 6 board feet.
But wait again! You will need some wood for the jig, if you are going to follow the plans. Notice - - the "we" became "you" when work starts.
I learned a couple of cool tricks for estimating B.F. from you after chewing over your post. One, add up widths and assume all pieces are the same length and two, assume the board you buy is a 1" x 6" since 1/2 it's lenght is the amount of B.F. Cool tricks.
The first time I read your post, I didn't read it with math in mind. I read it for methodology.
Here's my take using the methodology.
To get the rough B.F. estimate, 'we' add up all the piece widths to get the overall lumber width estimate. All the pieces combined totals 48"....check. This represents an imaginary board 48" wide.
Then, assume that all the project pieces are the same length equaling the longest piece which is in 'our' case is 6-3/8" rounded to 7".....check. This represents an imaginary board 7" long.
From the above, 'we' have an imaginary board that's 48"W x 7"L.....check.
Here's where things got real fuzzy for me.
If 'we' were to use a 0.00" kerf blade to cut this imaginary 48"W board into a board width that a lumber company stocks, say nominally 6"W (actually 5-1/2"W), 'we' would make 8.7 cuts or rounded to 9 cuts. 'We' now have 9 pieces, each measuring 7"L x 5-1/2"W. 'We' lay these nine 5-1/2"W x 7"L pieces on the floor end to end and 'our' imaginary board measures 5-1/2"W x 63"L. 'We' convert 63" into feet and come up with 5'3" and round up to 6'.
'We' believe a nominal 1"T (actual 3/4"T) defect free board - that's nominally 6" wide (actually 5 1/2"W) and 6 feet long will do the trick. Oh but wait, 'we' forgot that the project pieces are mostly 1/4" thick so that means that we can resaw the 1"T nominal board into two 1/4"T slabs, discarding the center as waste, thus halving the required total length from 6' to 3' .
That comes to a board that is nominally 1"X6"X3ft. ('We' should probably buy one 4 ft long just for kicks) This amounts to 2 board feet.
Here's my fuzzy. Where / how did 'you' come up with 10' / 6 B.F? Notice how the 'we', 'our' became 'you' at the first sign of a discrepancy!!
