    So where do you buy the composites and spruce in the lengths needed?
    I personaly would not use spruce. It is more prone to rot than doug fir. It may be lighter and stronger but if you get any water intrusion at all you will regret useing it. From what I have seen in most boats with wood stringers they have used doug fir. Spruce is not cheap, but if you decide to use it I do have a friend that sells it. No matter what you use for the stringers make sure you use an epoxy resin for the install. Good luck on your project.

    How did I know you were going to say that? Last time I was in there, though, the people acted like I was a bother and really weren't too interested in helping. I'll give it a shot again, just because they are so close to me, maybe 5 miles away.
    What is the best way to cut out full length stringers for total replacement?
    Thanks,
    Greg

    Yup..Sometimes ya' gotta let them know your even there..... Ask for Debbi or Michelle, tell them Mike from vacaville sent you over... If you have the old stringers to trace off of it makes it easier & cut on Bandsaw or a jigsaw....

    composie one is in sac and a lot cheaper than tap plastics. We built a boat with foam stringers and carbon. You need to up inserts in the hole so you dont crush the stringers. Good luck.

    Do they have a web site? Or do you have an address/phone number? I planned on using SS inserts on these old stringers until I replace them just to make sure that the pressure is off the wood, to a point. Thanks, Greg

    Hi Mike and thanks. I'll try that. I'm thinking about buying an old Sanger Shovel Nose (Bull nose) and I know it's going to need stringers, or so the ad said. Also, the dash area has holes that I'd fill and place the steering and gages where I would want them. Right now I've got to get my BUTT in gear and plug the old mount holes with some hard wood dowels and then re-drill and insert for new bolts. I'll give the dowels a skin coat on the inside of the stringers and then lay in a layer of mat on the outside. Got lots to do and seem to have dropped the ball when the motor let go.
    Darn, this summer went by fast and I've got a new engine coming back for the builder this week. I hope an Indian Summer comes along so I can get out a couple more times to see how everything runs.
    So much to do and winter is coming on.

    If I was going to build a new boat I'd use composites, no doubt. Doug fir and philipine mahogany are heavy compared to aviation spuce...think about it, Spruce goose? Light and strong.
    Don't use kiln dried, softens the wood.
    Comment with no real value-> The Spruce Goose is housed at my old Job in McMinnville, OR. (Evergreen Aviation)
    That is one big MoFo! All made from spruce, very light and strong!
    About stingers- I'm about to do some stringer work on my 75 Kona. I am toying with the idea of having solid carbon fiber/resin stringers. I know it will be heavey but who cares? I want to be able to trust that the engine won't start barrel rolls in the engine comartment. That foam would have to be some serious stuff for me to even think about using it to hold my engine in place. Besides, I have buttload of carbon waiting for a project.

    Kona's already heavy...
    You don't mean make a solid 2 x 6 stringer out of carbon fiber? Geez! Make an I beam or a triangle or a shape with strength.
    But since they already make a synthetic stringer substitute...why reinvent the wheel?
    Yeah, I may be over-engineering it like everything else. I just picture that 500lb piece of iron bucking around in there and breaking some foam stringers out like nothing. I guess that fiberglass is stronger than it looks. I have water inside my stringers for who knows how long and they still hed up fine with the Olds 455.
    What about 2x6's made out of hard plywood? I could put some serious clamping force on that!
    sorry for jacking the thread...
