I might be able to get my hands on some nice older sitka spruce and was wondering if anyone has experience using sitka for lams on glass backed bows. This would be for ASL and mild D/R longbows. Thanks, Dave

If it was good enough to build airplanes out of, it should be excellent for bows. I'm surprised it isn't used more.

I just glued one up last night with spruce and sassafras lams. I'll let you know how it shoots after I get it finished. Dave

Hmmmm. Don't know. Sitka spruce doesn't like to bend. I use it for canoe gunwales, and it's difficult to bend, even with steam heat, without breaking. May work OK sandwiched between glass. Let us know how it works out.

Backcountry, I thought of the Spruce Goose as well but as Orion stated, not sure how it will like bending. Although it sure had to flex some to be used on a plane. I could build a 4 lam ASL instead of my usual 3 which might help.
wendigo, yes, please let me know how yours works out. I've used sassafras before and I like it for lams. I've also used walnut, ERC, and vertically laminated flooring boo. All worked well.
Appreciate the responses.

One thing I forgot to mention, I used 5 thin lams in total. 2 spruce and 3 sassafras. The spruce lams were .070 thick. I pulled it out of the form today and cleaned up the edges. Glue lines look great, so hopefully I will be able to get it shooting in a week or two. I will get back to you as soon as I put some arrows through it. Dave

They make ASLs out of cedar, spruce is stronger, and most importantly, it is a lot more resistant to splitting than d-fir or cedar.
They do make airplanes out of spruce, though they don't normally make the spars with glass caps, so the analogy doesn't hold.
The Spruce Goose was just too good to pass up as a name, even though the main construction material was birch. An interesting fact is the nail or staple gun was created for that project.

Jack Harrison/Alaska Frontier Archery made a bunch of longbows with a Sitka spruce limb core. It's a very fast limb core but it didn't do well with longer draw lengths so they went to bamboo. A buddy of mine with a 29" draw shoots an American Wolf longbow by jack Harrison with Sitka spruce limbs backed with carbon and it hasn't failed yet and he's been shooting it for years.

Your right Justin. Jack had a whole garbage can full of spruce failures when I was at his shop. He got a grant to try to come up with a viable use for all the spruce the beetles killed. Not sure if he ever did find a use besides fire wood.

Thanks guys, all great information. This could be an interesting project. My draw is only 27" and I'm thinking I'd go with 4 lams on a slight backset ASL. Maybe start with 2 lams of spruce sandwiched between 2 lams of bamboo.
wendigo, love to see some pics and a little report once you're done.
