mickyd's Woodworking Projects

Sorry, Mike! I'm a little confused!

If I add the 2 board feet plus the five "scrap" pieces (4 ea at 1x4x8 and another piece measuring 1x8x32) This seems to me to be approx. 6.5 board feet.

Where is the rest of the wood?

Sawdust???

That is the total that he STARTED with, not left over pieces.


Color better???

These are three tiny little lanterns Chuck....not the 'spruce goose'!!!!

My initial 2 B.F. included mbcabinetmakers &#8216]

I used 144 cu. in. = 1 B.F. My 2 B.F. starting figure was based on actual measured dimension, not nominal size.

Crystal clear now you young whipper snapper you?

My initial 2 B.F. included mbcabinetmakers ‘scraps’, and the board purchase indicated. In addition, the units of measure on my stock lengths is in inches, not feet. That had to be what threw you.

Really Mike, you need to be more careful/accurate!(remind me to not cross any bridges you made stress calculations for)!:D

Use of[ '] and ["] or [in] and [ft]With or without a trailing period[.], would totally eliminate the 'confusion' alluded to.

• Keep making these omissions, and I will start referring to you as an old fogey!:eek:Coming from me makes you a really ancient being!

I have NO IDEA where that Bullet came from. Maybe some young grasshopper can tell me what I did to cause it!

• 'Spuce' is now 'Spruce'. I watch Elmer Fudd yesterday and he calls them "spuce twees".
• Although your technically correct, saw no reason to use ' or " as units for my lumber units. I mean now, other than Chuck , who would ever think these little things would have taken 64 linear feet of '1 by' lumber?
• Also, I'd love to see how I would have gotten that 1" x 8" x 32' board home, red flag hanging off it and all.

And also, I have no idea where your 'bullet' could have come from. You can't make bullets on this forum.

Would Elmer have called it a spuce gwose???:D

I see you can create them 'unconsciously' also!:rolleyes:

But how many ounces of sawdust???

Good question. I'll weigh my lanterns tonight and let you know. Those 1/2" x 1/4" stiles and rails created a lot considering a kerf of about 1/8".

As my Son reminds me - many engineer's errors are because lack of the appropriate UNITS.

The lack of proper units along with mirror images are both "huge" in the error column - so he tells me.

Yes, I inadvertently called the flooring boards as 1"x4"x8'. The 1"x8"x32" was interpreted as that size, because I didn't think you would buy a 32" long board. (An excuse - When thinking of board feet, I find it strange to figure length in inches.)

Told you I was confused.

So - I now understand (I think) the wood from mccabinetmaker was approximately 128 cu.in. Added to this was the 256 cu.in. of wood you bought locally. And the total of these pieces, expressed in Cubic inches is; 128 in.³+ 256 in.³= 384 cu.in. If this number were to be converted to board feet using a factor of 144 in³/ board foot, you would have started with 2.67 board feet.

By these figures (assuming my arithmetic is correct) They agree with your analysis. You started with a little over 2 1/2 board feet and had 1 board foot of scrap, not counting sawdust.

Man! That's a pretty good record for your first project and a really complicated one at that! Once again, Mike - Good Job!

Now I must put in a disclaimer in case some of my forester friends are reading this:

Granted, conversion from cubic inches to board feet is a very rough conversion, as board feet are not measured in exact inches. The two measures (Cubic and Board Feet) are really entirely different measures. To jump between the two measures is somewhat analogous to comparing troy weight to avoirdupois weight. (the reason a pound of feathers weigh more than a pound of gold) Conversions, or the lack of, between cubic and board foot measures have been the subject of endless discussions and disagreement between researchers and wood product people for a long-long time!

Another 'mistake is mis-typing the data! 384 makes more sense than 129.85!!!!!

Also ALWAYS use 'nominal' dimension when doing board foot calculations.

Thus a 1x8 is not 3/4" x 7.5"! You think that is confusing, a 2 x 4 used to be 1 5/8" x 3 5/8". Same for larger sizes.

In order for cu in to be 144 per board foot, one must use 'nominal' cu in, not actual. Thus a 1"x4"x3ft (1x4x36 = 144) is one board foot, not (.75x3.5x36 =0.656) board foot.

I do not understand any reason for 'endless discussions' if the procedure above is adhered to.

However when we delve into 'shrinkage' due to saw kerfs and moisture content, it does get a bit murky. Fortunately for us 'consumers' the nominal dimensions are pretty standard(for a given moisture content which most folks don't know or care about).

I find it interesting that the 'lumber industry' sells a 'finished' product priced by the 'unfinished' dimension of the raw material prior to ANY processing.
