Closed-cell seat foam Anybody have experience with it?

    Some might call me silly, but I have this ass-burning urge to re-do my seat.
    I have just enough knowledge to be dangerous. I have read about closed-cell
    foam vs. open cell foam, and I like the idea of having something that will
    last longer without absorbing water. I know there are some materials like
    polyethylene, polystyrene and polyurethane that aren't what I want, but what
    I was hoping for was someone with experience in this area who might
    recommend a certain type and density that is known to work. I intend to
    install gel pads as well. I have all the time I need, so the biggest
    obstacle I want to avoid is doing it three or four times before finding the
    right stuff. Any recommendations?

    Closed cell backpacking mattress pads from a camping supply place aren't
    bad. Good density and fairly cheap. Just don't let them sell you a
    ThermaRest unless you want to invent your own AirHawk.

    A good upholstery shop will also have a selection of different densities,
    but they may not be interested in selling it for a DIY project. Or they
    might just give you scraps. Depends on who you talk to, the phase of the
    moon, etc.

    I had a gel saddle when they were popular for bicycles. As far as I could
    tell, its purpose was to mold itself to your intimate parts to allow a more
    efficient transfer of road shock. After reading the reports on the factory
    gel saddle for the DR650, I passed go and went immediately to Corbin.

    The problem with many new bikes is the stock pan. The best foam in the world
    won't help if the foundation sags and twists under it.

    Bowman, Bruce, thanks for the input.

    I like throwing the gel pad idea out there, because every time I do I get
    some comments about them that make me re-think that particular want. The
    seat pan is one of those molded plastic affairs, and while it's possible to
    build a new one from composits, I would want another seat to use for pattern
    purposes because I couldn't stand to be without a seat for that long.
    I think at this point my biggest hurdle may be finding out how stiff a
    needle I need to sew leather on my wife's sewing machine. That, and
    selecting the right thickness of leather.

    adhesives, including one with 'memory foam'. Use an electric (turkey) knife
    for cutting. Marine grade stuff seems best for obvious reason. Thinking of a
    layer of dense, closed cell under a thicker layer of medium density, glued
    together into a single pad. Might want to try the 'memory foam' for the top
    layer. Have heard good and bad about gel pads, leaning more towards the bad.
    Best of luck with your project.

    IANAE, but many (most?) home sewing machines simply don't have enough
    power to punch holes in leather, no matter the needle. You definitely
    don't want to burn out the sewing machine on your project, but you might
    arrange for a trade: new sewing machine for more bike projects. ;-)

    Good luck with it.

    For a one-off project like this you might consider having a local shoemaker
    do it. Also, Tandy Leather, who have a website, have a book on handsewing
    leather which might solve your problem and answer your question. They also
    have leather, including upholstery leather, and tools and materials.

    I've already been to the local Tandy store, where I was pleasantly surprised
    with the offerings. I've handsewn leather in the past, which is why I'd
    much rather run it through the machine. :) A buddy of mine sews a lot of
    kites, so I'll ask him where he gets his thread that lasts so well. I'm
    pretty sure my wife's machine has enough oomph. It's one of those old
    Japanese things that's built like a tank. I just can't read the
    instructions. And any mechanical skills our kids have definitely didn't
    come from her, so getting good tech info from Japanese stuff can be a
    challenge. :)

    Nice links. Thanks. I think I'll stop by a sporting goods store on my way
    home to see the camping pads. The ideas are starting to take shape.

    One thing you can try with one of the old Singer type machines is to hand
    crank it.
    Slow but very powerful and nice and even spacing and tension.
    Can't burn out the motor if it ain't running!! :)

    foam. The good thing about it is that you can buy a small piece that would
    be large enough but so big it costs an arm and a leg. Please keep posting
    about project. Interested in how it goes. Mudge.

    Just had another thought. The reason I said earlier thet it might be best to
    lay out the covering, maybe glue it up with Barge leather cement, and take
    it to a local shoemaker, or saddlemaker if you're in an area that has them,
    is that there probably won't be enought clearance between the needle and and
    upright support of a standard sewing machine, even a heavy duty one. Most
    pro shops will have what's called a 'harness machine', which will be both
    capable of sewing leather and have enough clearance to do it.

    Not everybody can bid $20 worth of foam up to a Concours...

    $20? Dude, that's way over budget. It was only $7.00. :) The fact I put
    together enough cash to buy one last year, but bought her a new car with it
    instead, may have helped. :)

    at all, that will prompt a wife to tell a man to just get a new bike instead
    of doing has unlimited potential for greatness!

    And a mighty fine repair it has turned out to be. I heartily recommend it
    to anybody with seat issues. I need some reassurance the hammering sound
    emmanating from the cold engine is normal, though.

    Me first! I bid $300 for the foam as long as the wife changing
    attribute is guaranteed. : )

    A jeweler friend of mine has a saying that might apply here- "I can
    guarantee the ring, but I can't guarantee the girl". Switch foam for ring,
    and I recommend trying your luck with the $7.00 stuff. :)
