Terribly confused on how to buy rough lumber....please help!

[George Farra]

Hello Everyone

I'll be visiting my first hardwood supplier next weekend and I am very confused on how to request the lumber for my needs.

I used the board foot calculator on woodworkersource.net and it came up with approx 50 board feet w/ 30% waste. The final size of the parts range in thickness from 4/4 to 10/4 stock. Also, many parts can be cut from the same board as they are 4" and 2.25" wide.

So do I break down my order by thickness and total board feet....4/4 20 board feet, 5/4 20 board feet, 10/4 10 board feet.

OR should I have an exact list of thicknesses, widths and lengths....4/4 8" wide by 8' long, 5/4 6" wide by 8' long, 10/4 5" wide by 4' long, etc

I'm very confused

Thanks for your help

George

What type of supplier are you going to? I go to a local bandmill for rough cut and the sizes (widths and lengths) are not to standard dimensions. For example: a rough 6" board could be 6 or could be 6 3/4. 8 foot lengths could be up to 8' 6".

Sometimes I get my best deals on undersized material: 5' lengths, random widths. One sawyer makes me take whatever comes off the pile, and then, after its laid tight in the bed of the truck, rough measures it and calculates footage that way.

Have a good idea of what you need and make sure to get a bit more. Dimensioning your own lumber will reveal things you may or may not expect. Good Luck!!

George,

What you are likely to face is that the supplier won't have exactly what you want and you'll have to stand there and figure out (quickly?) what you can use from what he has and how you need to adjust what you buy.

If you have the necessary tools (bandsaw, jointer, planer, table saw), it is often better to buy larger pieces if it is vitally important to have good color and grain matching throughout the project (and frankly, this is almost always true).

You might get lucky and find boards all cut from the same log and then you won't need a larger, heavier board.

You may need to face glue boards to get the thicker stock you want.

As long as you know the rough final dimensions of your project, hopefully you can mentally mark the boards you will see in order to help you determine how you can build it from the stock physically in front of you.

When you've done that, grab an extra board just for good measure if you can!

I'd think that George would be able to get 12/4.

If the thick stock is for legs, you could always use the Stickley approach and glue 4 triangle-shaped pieces together to form the leg stock. The seams end up being on the outside corners.

He didn't mention what KIND of wood but if it is domestic, I agree.

George,

To answer your question - if you go in with the more detailed list (8" x 8'), it will make it easier to pick your stock. FAS lumber will be at least 6" wide, so take that into consideration when you lay out your planned cut list and 8' long.

[Michael Pauly]

You definitely should have a cut list in mind so you can pick out boards that will get you the most yield (or if you can't pick out boards, that you get enough to cover the waste). For example if you need 20 bf of all 5" wide pieces, getting 20 bf of all 8" wide boards is going to yield a waste of almost 40% in just the width, then you have to factor in the waste in the other dimension.

[James Hart]

George,

I make a little stick drawing of things I make and I assign a letter to each of the pieces (all four legs can be the same letter, for example.)
Take a sheet of paper and draw out rectangles for each of the pieces you need, with the dimensions of each piece written along the edges of the rectangles.

Take a look at the parts list drawing in a Woodsmith mag project to get a rough idea. The difference is that they lay it out as though you're buying dimensional lumber, which i don't think is what you're about to do.

Moving pretty quickly, I use a piece of white chalk and a tape measure to measure and mark the boards that will work. I then mark the parts on my sheet of paper with a check mark as i go. If one long thick board looks like it will give me all 4 legs, I just write 4XB (or whatever letter I assigned the legs.) on that board.

Then I get about 20% extra to cover mistakes, checks or other imperfections I didn't see, etc. If the wood is more exotic/expensive I might buy a little tighter, but not much.

You mentioned WW source. Are you in Phoenix? If so, maybe we can work out a shopping trip.

[George Farra]

Guys

Thanks very much for all the quick replies. I'm leaning towards red oak but may change my mind to cherry.

Its good knowing that FAS lumber is a minimum of 6" wide....I now better understand why the supplier did not list anything smaller in thier price list. The supplier is a lumber yard. I'm assuming they have a sawmill somewhere close by but not 100% certain. I'll find out when I get there.

The thicker stock is for legs. I'll do some research on the stickley method of glueing up 4 peices cut at 45's.

Thanks again

George

George, to specifically answer your exact question, the quote above is the way to do it. Just noting that you need 20 b.f. of 4/4 stock won't do it, unless your project is quite small or you don't really care whether you have to glue up stock to make panels.

For the first time you try this, see if the lumber supplier will let you come with a stick of chalk, and then chalk out your pieces on a board. Naturally, you will likely have to buy the board once you draw parts out onto it, but this will ensure that you don't leave the lumber yard with less than you need to do your project, which is often a much bigger problem than leaving with more than you need - it's unlikely you'd go over 50% more than required, and while no one wants to spend more than they need to, it's a rare woodshop that doesn't have a decent stack of off-cuts and a few extra boards laying around.

George, this may be obvious, but there are 2 types of places - those that let you pick and choose and those that don't. At one place , which I won't buy hardwood from, they sell mostly to cabinet shops and the rule is if you want 100 bd ft of cherry, you get the 1st 100 feet which is on top. Obviously you need to allow for considerable waste to account for warped, cupped, and knots. Most places I buy from let you go through the lumber and pick out the ones you like, so long as you restack it. Having a list of pieces and where they go, as Jim suggests, makes that go much better. First I try to only select from boards that are mostly straight, no excessive cupping or twist, or warp. From the pieces that pass those tests, I start looking to see what I can use, usually starting from the biggest piece I need and working down the list. I might see a piece that is 8 foot long but has some obvious defects at 3 foot from one end, I will see if I can cut pieces B1 and B2 from the short end and get piece C out of the long end. Or there may be some unattractive parts of one side of a board but the other is clear, then it would probably work as a bottom to a case piece, if it is the right size, but won't work as a side because both sides would be visible. Once I think that I have picked out all I need, I then try to find a few extra boards in clear straight defect free boards, even if they are narrow, with the thought that if all else fails, I can glue up some boards to get my finished sizes. Bring some chalk with you so you can mark the boards once you have decided to buy them.

[Michael O'Sullivan]

The other thing I almost learned the hard way a while back, is that if you give them a bunch of exact dimensions, they will mill the stock down to those dimensions and charge both an arm and a leg for doing so.

Don't know about you folks but where I get rough cut, I have to take the widths and lengths that they carry. If I want 10bf of 10/4 and all they have is 6" wide at 12', that's how much 10/4 I'd have to get. I'd probably opt for glue ups as it's rare I can get 10/4 especially in cherry. For a price they cut it to what ever sizes you want but you still end up with the entire board.
I bring a list of rough cut dimensions with me if it's for a smaller project and stand there and figure out what to buy when I see the lumber. I always end up with a good deal more then what it works out to on paper. For larger projects, I just grab boards that meet my needs till I have at least how much I need of each thickness. Nothing wrong with buying too much, it doesn't go bad if stored right.
Keep in mind the longest lengths you need. If you need a 6' length of 8/4 x 2" and the bds are 6" wide, your buying roughly 3 times what you need to get your 6'er.

[David Kreuzberg]

I buy my hardwood from a local sawmill who also kiln-dry the lumber.
I have them straight-line saw it (this is like running the entire board across a jointer), and also plane it (4/4 rough) to 7/8". This saves lots of time and wear and tear on my machines. With the stock at 7/8", I can go directly to glue-up for wider boards, then plane and sand to final thickness.

I've also found that you usually get the best (straight, not cupped or warped) lumber by buying 12' lengths.

Bob - Just a thought, but if you want wide, thick cherry, you're pretty close to Irion Lumber in Pennsylvania (relatively speaking). Generally, they have massive and very high quality boards, and it's one of the few places in the country that do. You will pay for it - generally about 20% more than you would for an equivalent board at another place. But, of course, those "other places" generally don't have such boards.

I've bought a lot from Irion, and when quality counts, I highly recommend them.
