So just got started on my frames and have most of my doug fir for the boat, then suddenly I noticed that all my wood is 1/8 smaller then it should be. All 1x4s that should be 3/4x3.5 are smaller. So did I just buy the wrong thing? Cant really afford to restart so im just using what I have, my biggest concern is my chine... will this smaller size wood have a huge loss in strength?

 

O well, its a learning process and after this first day of building I have already learned so much.

You can use what you have without any problems, the loss in strength will not be huge.

If it is at all possible you should use white oak for your chine log and the chine batten. 

Randy (being the expert that he is) is right.  You won't run into problems with strength.  To boot, the chine log should be 5/8 and not 3/4.  It is MUCH easier to bend.

 

But...  I used to work in the lumber industry and unfortunately, like all manufacturing, we ran into defective product too.  You should take back your purchases if you are unhappy, because, as you stated, 1x4 nominal should be 3/4x3 1/2 actual.

i renovate houses for a living, and i spend (on average) $1000 a week at lowes.  out of that money, i would bet 2% is on lumber.  they simply have an inferior product, across the board (wood wise).  please, everybody, do yourselves a favor and build a relationship w/ your local lumber yard.  it doesnt take much to get on a first name basis w/ most average sized lumber yards, and once you do that, they will bend over backwards to help you.  not only that, you will be stimulating your local economy instead of big box lowes or HD.  i am now stepping down from my soapbox.

 

lowes/HD are great when you have ten different things to get, but for wood it is terrible.

Ben:  Randy and Jordan are right on the mark.  When you take the wood back look for a good piece for the chines with minimum  grain runout.  Yesterday I  snapped an inwale.  I gambled using a piece with less than 12" of runout.   The ben in the chines will be severe- so look for a good piece with 18" or more of runout.

Good Luck
