    For anybody who's interested, here's some pictures of how I'm rebuilding
    my seatpost. I've been riding the FMF Powerstick seatpost, but I've
    broken two of them where the head joins the tube, and as I hate the
    clamp designs on the steel seatposts available in my size(22.2mm) I'm
    rebuilding my powerstick to be a solid aluminum post. It weighs about
    12 oz. but I'm hoping it'll much stronger than my previous post.

    I've simply machined a 1"x1' aluminum bar down to size with a .535"
    diameter stub on the one end that I press fit into a hole on the head I
    broke off the FMF post. All that remains is for me to find someone to
    weld the joint for me. Sorry I didn't take any pics of the head and
    post before I pressed them together.

    When you use the IMG tags, you need to put the url of the picture and
    not the page that the picture is on. Depending on your computer, right
    click the image and either click properties and get the image url or
    click copy "image address" or something like that.

    I knew I was doing something wrong, but I was too tired last night to
    figure it out. Thanks Spencer.

    I got it welded today, cost me $10, and I got the aluminum for free, so
    I don't think that's too bad of a price for a new post.

    Nope, doesn't it need heat treated to be strong? I know nothing about
    metals and such, excuse my ignorance. That does look rather nice,
    hopefully it works better.
