    Thanks for the info, TeeDee. I'll try making an IX UQ for my blackbird along your guidelines and see how it goes. I know you made a bridge-specific UQ, but any other suggestions from your experiences which would apply to a gathered-end hammock? Sounds like I should try to get the inner lining designed to fit snugly, then build the outer layers around that?

    For a real good fit on a gathered end hammock, I'm thinking of making an insulated hammock sock with the top removed, kinda like a HH SS UC.

    Thanks TeeDee.
    I apprecate you posting your ideas and feedback. Another IX TQ is on my list of projects to do. The IX TQ that I have now works fine but, do beleive the differential setup that you made, will work better on it's own and deffinately work extreamly well when used with another TQ to extend them to a lower temp rating.

    After making stuff for a Hennessy ULBA a few years back before moving exclusively to my Bridges, I think that fitting under quilts, under covers, top covers, socks, etc to gathered end hammocks is orders of magnitude more difficult than a Bridge.

    That is a long winded way of saying that I have no insight into fitting stuff to a gathered end hammock.

    I can only say I know it can be done and done well since Hennessy succeeded very well with his SuperShelter.

    Fitting full-length underquilts to a gathered end hammock is difficult, but fitting a 1/2 or 2/3 underquilt is pretty easy if you do a differential. The problem with a full-length one is fitting it to both the curve of the back and under the legs at the same time w/o compressing anything.

    I imagine that problem is still there with bridges, but MUCH less pronounced.

    MUCH less.

    Fitting to a gathered end hammock is a compound surface, i.e., a surface that curves in more than 1 direction. For the gathered end hammock, you have the bottom surface curves from side to side and also from end to end. You have to fit the under quilt to fit both curves at the same time. Not an easy task.

    The Bridge is much easier to fit since the end to end curve is drastically reduced compared to the gathered end. So much so, that it can be virtually ignored. Not entirely, but mostly.

    What really makes a Bridge much easier to fit, is that it is possible to make an exact duplicate of the Bridge and use that as the top shell of the under quilt. Hang that from the four corners of the Bridge and it is a "second skin" for the Bridge. Fitting is done. 2 exact Bridges, the second as the under quilt top shell.

    This "second skin" approach for the top shell of the under quilt has another decided advantage in that air leaks and air pockets are totally eliminated. They are simply not possible when the "second skin" is made properly.

    This also makes flexible pads such as the GG ThinLight pads on top of the "second skin" and under the Bridge work very well. The pad is essentially "molded" to the occupant.

    This, of course, assumes that you make your Bridges from a pattern and so can cut both from the same pattern.

    If it was possible to do so with a gathered end hammock and arrange to hang it as a "second skin", then the same could be done with the gathered end hammock. I think making the exact duplicate would be easy, but hanging it under the gathered end would be problematic. That is why Warbonnet's double layer hammocks work so well.

    The second thing that makes a Bridge so much easier to fit is that once you have the top shell fitted as above, you can reduce it to a 2 dimensional problem, i.e., reduce the computations for the outer shell fabric to computing the fit from side to side. If you have used a computed arc such as a parabola, then you can do all of the calculations easily before ever cutting fabric. Hang the outer shell from the top shell "second skin" fabric and it is very easy to compute and fabricate the outer shell to eliminate any compression of the insulation.

    Thanks. I may use my HH SS as a model for this and see what I come up with. Making a mock-up or two out of cheap fabric until I get it right may be the best approach.

    Very good points, TeeDee...especially this one.

    Hey TeeDee, so I get the idea that you don't want the IX snugged up against you be cause that would make a cold spot. But in the UQ application, how far away do you want it to hang? From your instructions, I'm picturing that you would have maybe 3 or 4 inches of air under your butt and shoulders. (Not that I'm picturing your butt) How much space would be too much?

    In my original experiments I was trying for 1/8" to 1/4" air gap under the butt. Never could get that reliably. So I just opted to do the simple thing and use the full 60" width for the end width for the under quilt. With 9" deep arcs that leaves 42" center width for the Insultex and bottom shell material. This is for a 44" end width Bridge with 6" deep arcs.

    The amount of air under the butt? about 1/2" to 3/4".

    If I had the money to buy lots and lots and lots of Insultex from Mac and more 1.1 ripstop and lots of time, I would experiment with varying the Insultex end width from 50" to 60" in 1" increments and see how much less than that 1/2" to 3/4" air gap is optimal, but it's working now, so I'm off to other projects.

    Making more Insultex top quilts and under quilts for family - I can now make a top quilt in 1 day with maybe only 1 or 2 obvious sewing blunders and minimal swearing.
