The Douglas Fir thread!

    Being a woodworker born and raised here on the West Coast… You’d think I’d have a stash of Douglas fir in my wood collection dedicated to instrument building. Instead, I have handled and gone through hundreds of pieces of Doug fir... whether be reclaimed or fresh off the mill or stock shelves at the local Lumberyard. Many of which were of a very high-quality… Very tight, straight grained, heavy beautiful stuff.

    Up until yesterday, I have assumed Doug Fir wasn’t really a suitable Tonewood for instrument making. Thus, its use has been relegated to largely finishing Millwork and or fine furniture pieces IME.

    Yesterday, I was at the lumberyard grabbing some jamb material for my own home renovation… And across from me in the VG Fir section (not hem-fir) was this big ol’ banana’d s4s 2x10 (1.5x9.25) that looked to have been there quite a while. Being the wood snob that I am... I immediately noticed the figure popping out of this board along its entire 10 foot length. Upon closer inspection… I realize the whole thing is curly, right through to the other side and is heavy as hell. Well as you can imagine… I excitedly bought the thing for a measly $7.50 per board foot. After loading it up in my van, I Google search “Douglas Fir guitar” thinking; someone must be using this stuff in guitar builds!?

    Well, I find out that I have been sadly misinformed about this useful species of wood. After seeing several dozen fantastic images of solid body and acoustic guitars with curly Douglas for tops... I go down the rabbit hole only to discover that Doug Fir can and is being used today for everything from acoustic tops & bracing as an alternative to spruce, to solid body tops and even bass/guitar necks instead of maple! Too cool. I’m so excited to build on my specialty Doug fir stash and incorporating the species into future builds!

    For the sake of inspiration... Show me your Douglas Fir! :)

    Nice find; I love it for solidbodies, although only if it's quartersawn which you don't find much around here in 8/4 stock. I also use it for back bracing in acoustics and I have a nice quartersawn 1x3 I've been planning to try for a neck. Have fun with it.

  3. That looks really nice. I didn’t know fir did that. I have used Radiatia Pine for a body but never Fir. Looking forward to how this turns out.

  4. I have a chunk of curly clear 2x (12?) Doug Fir that I salvaged off a job site years ago, and have never done anything with. I’ll try to post a pic. Very unusual stuff!

    I would be fine with a body for a bass made of Douglas fir, but it'd have to be well seasoned/dried - the new stuff for building houses is usually green and wet - not yet stable. If you've ever driven screws in an old house where the Douglas fir studs are old and really dry, it's very hard, tough stuff - the screws literally SCREAM when you drive them into old Douglas Fir.

    There are a lot of pine bodied solid body instruments out there - using coniferous woods (well dried) in that application is completely reasonable. But I wouldn't chance a neck made out of the stuff.

    ^ totally agree. This board was kiln dried before it got to the “lumberyard” which in this case was the finishing section indoors where all the KD lumber lives. Guessing by the overall curve and patina on the board... I’m guessing it’s been indoors for at least a year after being kind dried.

    Im planning to cut it down into a few different lengths, flatten those sections and maybe resaw the ones I plan to use as tops. Then I’ll sticker stack it for a while to see what happens. I might even try roasting a section as well!

    Looking forward to it. That's a lovely bit of wood.
    Dried through and through I don't see why you cannot make a bass out if it. They made them from ply and those sounded fine.

    One of the best woods out there in terms of stiffness to weight ratios. It's a shame it gets a bad rep as a cheap species only good for 2 x 4's because it makes an excellent top for acoustic instruments. You just can't sell them, because it's not a famous traditional species.

    Not highly figured but dry and stable. I found a big piece holding up a porch on an old house. Cut it into this blank for a "National" short scale build. At 1-1/2" thick it is still 4 pounds 12 ounces so not a lightweight. IMG_7119.JPG
     
  14. Wow I really dig the wavy figure, that's almost a redwood looking grain pattern.
    Density is what usually drives me when looking at new species/varieties.

    Good luck, I can't wait to see what you build out of it.

    All the pictures of figured doug fir instruments that I’ve run across online look very similar to redwood. Less red in colour of course by similar. I’ve got some curly redwood in my stash as well and this fir is WAY desnser and harder. The redwood is featherweight by comparison.
     
  16. My house is framed with Douglas Fir.

  18. Cool! Im a PNW guy too!
    I have an old Ibanez neck that i have been thinking about building a body for and have been thinking fir and/or red alder.., we have an abundance of both. All just a thought At the moment. I’ve been wondering why fir isn’t used much.
    This is a deck I’ve been helping build... all fir decking that we milled from 2x4 and 2x6 lumber and finger joined to get continuous length. Very pretty,

    You PNW guys have a lot of awesome native tonewoods. I'm envious of the redwood and myrtle especially. And the claro walnut, and all the fruit and nut trees...
