    Talking DIY 3/4 Differentially Cut UQ - Finished!

    I finished my UQ this week - wohoo!

    Thanks go out to everyone who shares information on these forums, which without, I never could have imagined taking on such a project. This is my 1st DIY ever and I have no prior experience behind a thread injector. It took me a long time to wrap my head around some of the concepts involved, but well worth the effort. Special thanks go out to my wife who put up with me taking over the dining room table and kitchen floor for a week during construction!

    Number of baffles: 7.00
    Baffle height: 2.50 inches
    Underquilt width: 42.00 inches
    Underquilt length: 52.00 inches
    Seam allowance on long sides: 1.00 inches
    Seam allowance on short sides: 1.00 inches
    Width inner fabric (toward hammock): 42.00 inches plus seam allowance = 44.00 inches
    Length inner fabric (toward hammock): 52.00 inches plus seam allowance = 54.00 inches
    Width outer fabric (away from hammock): 54.00 inches plus seam allowance = 56.00 inches
    Length outer fabric (away from hammock): 57.00 inches plus seam allowance = 59.00 inches
    Baffle spacing for inner fabric: 6.00 inches
    Baffle spacing for outer fabric: 7.00 inches
    Outside chamber width inner fabric: 6.00 inches
    Outside chamber width outer fabric: 9.50 inches (7" +2.5" loft)
    Darts on the inner: 1 inch (total 7 inches)
    Darts on the outer: 2 inch (total 14 inches)
    For the head end I made these 10 inches long, and 15 inches at the foot end.

    Down Fill Calculations
    Volume based on trapezoidal pyramid shape of radial baffles calculated above
    Down fill power: 800.00 inches³/ounce
    Percent overfill: 0.20
    Volume per baffle: 844.83 inches³
    Total volume: 5913.79 inches³
    Down per chamber: 1.27 ounces
    Total down: 8.87 ounces

    The above calcs started out using Meteors UQ Calcs:
    http://www.hammockforums.net/forum/s...d.php?p=553311
    And were then modified slightly (using 160 degrees instead of 170) to simplify dimensions for easier construction. (Thanks Meteor and Mad777!)

    Ripstop and Noseeum purchased from: http://www.diygearsupply.com/
    Down harvested from a Bloomingdales My Luxe pillow.

    On to the pics!

    Laid out and marked



    Baffles and darts sewn to outer



    Baffles sewn to foot and head end, also showing corner detail



    Shell completed, baffles sewn to inner and outer shell, 3 sides hemmed



    Shell filled with 800 FP down, Grosgrain channels added





    And finally, suspension added and attached to hammock!








    I hope in the future someone will find a small nugget of info somewhere that helps them as much as it helped me looking through other projects!

    Outstanding job, HappyHiker!!!!! You made a fantastic UQ!
    I made one with about the same statistics and it gets me down into the teens easily!

    That's a perfect looking quilt for a seasoned artisan - beyond incredible for a first timer!
    I can't wait to see your work a couple of years from now, although, I don't know how it could be improved upon

    I hope so, if not for others who have done the same I never would have attempted it. Yay for HF!

    Perfect! That's the temp range I was shooting for.

    It fits the 5 foot rule well (don't get closer than 5 feet and it looks pretty good) Maybe in a few years I'll be able to stitch a straight line.

    Really the only reason it turned out so well is because of yourself and others who posted info on their projects so that others could see how it's done.

    I think my next couple of projects will be much much simpler (need a bit of a break haha). I have a new appreciation for how much work goes into some of this gear!

    If there's one thing I haven't ever made that I've always wanted to, it's this kind of project. You've done a top-notch job of it and should be very proud! Kudos to you.
