Off Topic / New (gingerbread) machine

Figured some of you might enjoy this gingerbread Juki, or Julki ("jul" means christmas) we made at Norrøna for a gingerbread competition.


We couldn't get the thread through the take-up lever so if anyone have a suggestion to fix this we'd appreciate it! ;D

I have the same machine and am running A&E T-70 through a #21 needle, between 800-1200 SPM?
Along with thread tension as stated above, I had great results by replacing my hook with a new Juki branded one. It costs a few dollars but my stitch was noticeably better.
I also give the machine a good cleaning in the hook area as well as cleaning the gunk out from under the bobbin case spring when I notice problems.

Sil-Nylon can do this as well, but curious to see where this goes.

Materials science / Re: Alternative Fabrics for direct on-skin contact

Fleece (Malden Mills' Polartec and others versions) has been used in the outdoor climbing community for decades. In fact, they were using it to line the inside of climbing harnesses back in the late 80s. Companies moved away from it, even on the waist belt (many rock climbers climb without shirts in warmer weather), so I assume there had to be some issues. Perhaps durability was an issue – fleece is a knit fabric.

   

Having climbed in a number of harnesses that used fleece to make them more comfortable, it does do that on a contact basis, but it is too warm to be worn directly on skin while cinched tight against the body. It will get wet from perspiration, and leave a brief clammy feeling when removed. It works well when there can be airflow either through or around it because it is loose. I don't know that this is why it isn't used as much, since closed cell foam between a woven and nylon and webbing doesn't exactly breath well either. I think that it has more to do with Arc’Teryx re-writing the book on how climbing harnesses are built and fit. After that, everyone else had to catch up with their designs.

Agreed. The thermo-formed Vapor (and Zrill) re-wrote the book on harness construction – and yes they were completely non-breathable!

You still climbing?

Not much these days, still spend a fair amount of time in a harness doing chairlift evac trainings, rapping out of places I shouldn't have been with skis, and running our resort rope rescue program. We have hit the gym with the little guy a few times and it has been nice to move that way again!

Thread - 69 nylon bonded, I did switch spools soon after my last post and this spool is functioning well.

After I got it dialed in, I also adjusted the cutting knife moving blade and checked the other blade for spec. I need to play with this some more as I occasionally get a tack that doesn't cut the needle thread. I didn't check the knife edge, so it could well be a dull knife for this issue.

Neat machine to start learning about, thanks for all the support!
