Hi,
I have a Juki 1181N that I do most of my sewing on. It has been mostly trouble free but yesterday it started misbehaving. While reversing the the thread started partially breaking and bunching up before the needle eye.

I checked the needle timing and it was a tiny bit of so I adjusted it, swapped the needle and the throat plate since it started to be a bit worn. After that I haven't been able to get it to run good at all. If a go slow trough only two fabric layers its running ok while reversing, not good but ok. But as soon as I increase the speed or add more layers the thread starts forming large loops on the underside or breaks. It seems to start unwinding through the tension disc as you can see in the picture.



Forward it seems pretty fine, if I look closely it looks like the thread starts to unwind through the tension disc but I'm not really sure. The thread is Gutermann Mara 40 Z-twist but i also tried some other threads.

Anybody have any ideas of what to adjust or change?

I use Onewrao for some applications but it will always have one hook side exposed to scratch things or get caught in clothes. I need something "onesided". Good suggestion otherwise, its definitely stronger than normal velcro

Materials science / Stronger/thicker hook and loop
« on: August 25, 2017, 04:48:48 AM »
Hi, I have a few bags where I sew velcro to webbing to strengthen it but it's very time consuming and hard to get the finish perfect. I would like to find a thicker, more durable velcro that I could use on its own instead. It's usually not the hook and loop interface that fails first, instead the velcro starts fraying in the edges or it rips apart at the seams if I would use it on its own.

I'm primarily looking for black with an EU source but I could buy international aswell if needed.

Binder clips :) Preferably metal but I have some longer plastic ones as well I got cheap of ebay.

Nice! i usually reinforce thinner fabrics with a small piece of fabric with a heatsealable coating on it. Cut a square with rounded edges, melt it to the fabric with an small iron. I use the same technique to reinforce fabric when I add grommets

Vendors and sources / Re: Source for g-hook alternative?

Funny you mention this. I just saw a Duraflex alternative which doesn't seem to have reached suppliers yet. "Ghost Eye Tensionlock with Hook". If someone can chime in with Duraflex suppliers I will bird-dog more information.

Nice find! I really like how they angled the hook outwards, should help keep it secure!

I just sent Rita at PK supply an Email, I hear she is at a show this week and may be around the Reps.

Rita replied to me today and said she would look when she got back to PK, I will post a review of the sample here if she can find one to send me.

Great! Keep us posted!

I found an ebay seller with some of the Woojin buckles, but he wants 1.5 dollars each plus ~30 dollars shipping :/ Kind of steep but I might go for it unless I can't find another source.

Vendors and sources / Source for g-hook alternative?
« on: August 05, 2016, 08:32:35 AM »
Hi! I want to get rid of some buckles and use hooks instead but I'm struggling to find a good source. Needs to have a ladderlock style tension mechanism built in because of space limitation. I have tried g-hooks but their tension mechanism is as we all know, not very good. Plastic or metal doesn't matter, but it needs to be fairly strong. They will be used to attach various different, optional, pockets or to close rolltops. The main reason why I want to use the hooks is that I don't have add extra buckles to the main bag, only a small webbing loop. I have considered using ITW Quasm molle buckles that the user would add when needed but I want to try and avoid those sorts of solutions to keep the user friendliness up.

Would prefer 20mm as that's what I use today and larger is a bit overkill.

I have looked at Woojin who have some hooks that looks very good, but I haven't found a source that sells low quantities.

Extremtextil also have an alternative but only in 1 inch/25mm. No mention of manufacturer.

Any recommendations or alternatives?

The inital idea for the bags came from another product I've designed and selling, a smaller bag for bikepacking.




It's meant to be mounted on the downtube on mountainbikes to hold spares, first-aid kits or other things you want easily accessible. That bags works really well with only the non-slip fabric on the back of the bag. A local guy saw these and wondered if I could make a couple of larger ones for him. The down tube bag is only about 1 liter big, he wants them around 5 liters and capable of holding much more weight. His idea is to have some spares and first-aid stuff in them so when he needs it, he won't have to dig through or lift out all the other stuff from the back of his car. I've made two prototypes(sorry, no pictures, their in his car right now), but they spin too much so I need to anchor them down better. My thinking is if I could have a non slip-coating on the webbing going around the roll bars they should be much more secure.

I found webbing like this but only avaialble in bulk:


TPU or PVC coated webbing.

That would probably be too thick and stiff to work in the buckles. There's also elastic with a thinner coating on only one side.


Polyester or nylon webbing with a similar coating would probably be perfect for my needs and that's what I'm trying to source.

Introductions / Hi from Sweden
« on: June 15, 2016, 12:53:56 PM »
Hello everybody, I'm an engineering and Industrial Design student from Sweden that just registered here after browsing for a while. I found this forum while looking for some inspiration from tactical stuff to try and include that into the outdoor and sport stuff I'm designing and making. I've always found it quite interesting to see how different industries are approaches and work with similar materials and problems. I hope I'll be able to learn a lot and contribute with my own knowledge!

Hey,
First post here on the forum. Been browsing for a while but finally signed up. So.. I am looking for black polyester(preferably) or nylon webbing with a non-slip coating on one side. I've been asked to design a couple of small bags that are meant to be attached to roll bars on an friends custom jeep-motorhome hybrid thingy.  I need to attach some bags to the metal bars but having a non-slip fabric on the backside of the bag isn't enough. The bags are strapped to those bars with webbing and I think if I had webbing with coating as well it would be enough to stop the bags from spinning and moving. However I haven't been able to find any except some polypropylene coated stuff on alibaba. That's not going to happen so I figured I'd ask here if anybody knows of a source?

Polyurethane, silicone or something else doesn't really matters, but it needs to be fairly durable and not to thick so the webbing can still be used in buckles. Same with the "pattern", full covered or partial covered shouldn't matter.

I'm looking for around 10 meters, preferable 20 mm (3/4 inch) or 25mm(1 inch)wide and i'd prefer an European source since I'm based in Sweden but I regularly buy fabric and webbing from the states so I'm open to everything.
