I've seen a couple threads here about chainmail blankets for assorted purposes, and there are the occasional hits across the web too.
I'm not trying to cure RLS or calm an ADHD child, I just grew up in the great white north and work has moved me to the desert. I missed the weight of blankets and wanted one that would actively cool instead of insulate. Metal was the obvious choice for high thermal conductivity and surface area, and maille was a natural mode of construction. This place was my next stop.
I'm sure most of you folks have been excited about a box like this one that delivered three months ago:
This was my very first foray into mail construction, and it seemed pretty daunting to start off with a 20lb, spool but my girlfriend deployed so I have time on my hands. I wound all 20lbs into coils in a weekend spent on my front porch. I lost a little blood to springback despite knowing it was there, lurking. Took me a little bit to refine my technique, I guess.
First milestone: big enough to sleep under. Mid-June, I had made an aluminum bath towel.
(un-embedded, too big)
Tonight's milestone: it drapes off the edges of the mattress!
I'm sure lots of you have worn this stuff in cooler weather and know just how effectively it serves as a radiator, so you'll understand how my AC set to 78F means I wake up shivering some nights. It may take a couple years to break even on the cooling costs since I only cool my bedroom, but this is infinitely more comfortable.
Now for the technical stuff where you're the experts: as I move out to the edges of the project, should I be concerned with stretching? This is 14g bright Al with 5/8"+ID. I need enough drape to prevent the edges from rolling onto the bed and bunching up around bodies, because the next thing that happens is (thanks to the 4-in-1 bias) a lengthwise expansion where the sheet drapes off the foot of the bed, and suddenly my blanket is made entirely of wheels in a race for the floor.
My friend's sewing a dedicated flat sheet with some ties to attach the rings, but that won't be rigid enough to resist 20lbs of gravity if the thing decides it's go time, so the side tension is important.
If total weight/stretching is a risk, should I reduce the weave density off the sides, maybe by leaving out one in eight of the 4e1, or even further and just putting strands/tassels?
If i want to increase the weight of the sheet at the neck/shoulder edge to help resist rolling down the body's taper, what's a good way to do so? Switch to a few rows of steel, weave the aluminum in a thicker pattern? Both?
