Hello Eric! Hi people! When you make such a tight stitch, you "dissolve" the material, killing its ability to be strong and perform its bearing function. Apart from an aesthetic function, such a stitch does not carry any other load. My deepest respect and IMHO
Hi Eric, there is a small spring arm on the bobbin case that you need to pull the bottom thread into. This may solve your problem of having the top thread get sucked in. Cheers.
Great video Eric. The alumni goal flashback was a great finishing touch.
Thanks, definitely one of the more weird creative goals I've ever scored.
Just purchased a sewing machine so this video is beneficial. I see I need some patches to practice and learn the various settings.
I enjoyed the hockey replay.
Awesome 👍 Best of luck with your new machine.
Just remember, not all sewing machines can sew all leathers! One can burn out a sewing machine motor….don’t ask me how I know.🎃
The only thing I'd add is stitch length; for woven fabrics, you can almost run any stitch that catches at least 1 woven thread; however, with leather, other natural products, plastics, rubbers, the structure is essentially uniform; strength comes from the cross section of the material; a line of holes is a perforated tear line. So for most of those, a stitch length that is close to or less than the thickness of any individual layer is asking for failure. 2x & up is often better lor longevity, tho often undesirable for appearance.
Consideration for thick thread (and the thick needle/hole) may also be necessary.
If you're using a natural material, expect variation in material properties: natural leather is not uniform, and you need to know about the various properties various parts of the hide have.
Glue/alternate binding can help, but even then you don't want a 1:1 or lower ratio.
And the softer the material, the wider the stitch, if you can't legthen the stitch while maintaining sufficient hold/tension then go to a glue
Yes, very sound advice! Thanks for sharing that with everyone here. Much appreciated
Add more tension to top tread.
Great video. Learned much on seam stitching. Sewing is harder than welding. : ) Mahalo for sharing!
Woot woot
thanks for making this video. i feel like there aren’t many industrial sewing videos out there. as an amateur industrial designer. this answers a lot of soft good assembly questions, i hd been trying to figure out.
Awesome
hope to see videos about overlock
Actually. "lock stitch" refers to the kind of two thread stitch that sewing machines make. The top thread is poked through the fabric, looped around the floating bobbin and then pulled tight.
It is distinct from "chain stitch" which uses only one thread. A loop is poked through the fabric and through the center of the loop from the previous stitch. I think chain stitch is still used to close bags of bulk goods like cat litter and gardening products. If you can find the end you can just give it a tug to unravel it. Chain stitch is also what one makes when crocheting.
A serger makes an "overlook stitch". These are used to protect what would otherwise be a bear edge. This involves multiple threads which loop through each other and around the edge of the fabric in a complicated way.
Super helpful information Eric, thanks !
You're welcome, good luck on your projects
I have been looking for an old industrial machine to purchase. Great video! I enjoyed the hockey footage! Nice goal!
Thanks, I have another video about how to modify your industrial sewing machine. You should watch that, you can pick up machines pretty cheap on craigslist
Very helpful, thank you!
the thread issue 4:33. what i have found is usually it’s a one of three things. thread tension too loose, i’m not holding tension on the access thread as the first couple stitches go in, or when i finish a stitch run, i don’t turn my wheel so needle is too dead center , and enough and it won’t let go of the thread
Good insight, I will note that next time I use the machine
Very interesting. I bought a HD Singer for just that type of sewing a couple years ago and I'm afraid to take it out of the box!! Maybe this year. LOL. Thanks for the video, it's going to MAKE me learn.
Good luck
To stop the top thread staying 'sucked in' (at 4:35 min) simply make sure the take up arm has gone to its highest reach. This releases the thread from around the bobbin,. Cheers
I will make a note of this. Thanks
That's a cool clip in the end of the video man! Do you still play hockey? I grew up rollerblading and we played street hockey abit never had the opportunity for ice hockey because there wasn't a rink close by lol but of course now there is a rink 10mins from us ha ha funny how things like that always happen ha ha! Thanks for the cool video I always like learning about stuff I have no clue about and this was informative.
Yes, I still play once or twice a week. It's a must! And it's so much fun.
Digging the goal. 🙌💯💯
Thanks for sharing this. I have a couple of machines I rarely use. Overlock machine is my nemesis but the finish is 👌 Do you use that at all? I use it for clothing.
Nope, I only have a straight stitch machine, no overlocking capabilities whatsoever.
Regarding the thread getting sucked in, someone said tension was the issue. I just had this issue and in my case it was the timing. I don't know how your machine works vs mine, but on mine, the bobbin was too too far into the rotation. It required a very small adjustment on the bar driving the bobbin. I was unable to resolve it by rotating the bobbin holder.
I'm not saying tension is not your issue, though. In many of your examples, you can see your tension is not adjusted correctly as illustrated by the thread from the other side having been pulled through and visible.
So, I suspect you are correct about the timing, The issue is not consistent and does not seem to have anything to do with thickness of materials quite honestly. I may need to have the machine serviced or figure out how to adjust this timing issue
The threads get sucked beneath the needle plate because the thread tension is too low. Also this is made worse by flexibility of the material being joined, such as spandex.
I will investigate that. Thanks for the feedback. Much appreciated
@@EricStrebel Just to add to that, the bottom thread tension is higher than the top thread tension, it's a game of balance between the two tensions. Slippery fabrics/threads make things more "sensitive" to any imbalance, as do fluffy fabrics like fleece
Okay, more good information! Thanks 👍
Not really, most likely he is trying to remove the work on the wrong position of the hook. Thread take up lever must be all the way up so you can remove your work the easier way, the hook will be on opposite side of the needle so the loop will be completed and the take up lever will pull al the lack underneath the top thread. for best results remove your work with the thread take up lever when its moving its way down but still up. This way whenever you re-start sewing you will require less effort to hold your upper thread on the first stitch.
Ahhh, interesting.....never thought of that
If the thread is getting buried around the bobbin, in my experience, it turned out to be that the needle wasn’t heavy enough for the thread/fabric combination. The thread gets stuck in the groove of the needle because the groove isn’t deep or big enough to allow the thread to slide back easily when the tension arm is pulling it back. I ran across this when stitching upholstery weight fabric. Thought it was a tension problem for a long time.
Cool, good to know, I will investigate
Oooh, great info. I'd have thought it was tension as well.
Do you have a video or list of some sort you could comment or email me containing ALL of your preferred tools for stitching sewing , foam board stuff, kilns and ceramic + mold casting also, vinyl and how to work with it, and basically everything to do with creating Knick knacks I can personally theme to a festival I’m working or merch for a band or a rapper that’s hired me on, etc. I’m attempting to start a business in the field of industrial creation NOT cheap DIY crap although I may have to start there to get the income generated at first. I’ve already got a few ppl on board such as my fiancé and long term best friend from childhood and I’m currently 28. I want to do commission work for interior design and decor with my own pieces of Artificial plants and custom built furniture that doesn’t look like middle school art class. I know it’s all about the technique and practice. But being a professionally trained classical and jazz pianist who picked up audio engineering and the skill of sound design mixing/mastering recording etc , trust me when I say the professional tools I researched out and invested my own money in not only helped me get better faster, understand it more in depth just by trial and error, but the sound quality of a composition on ableton using native instruments Komplete aka bundle of synths and other digital software for your “canvas” aka Digital Audio Workstation aka Ableton, but practicing sound design instead of depending on presets is what took my work to another level than had I stuck with garage band and used presets. There’s no comparing the two, and I’m a professional in every sense of the word , I’m not a shoddy DIY hobbiest looking to make a quick buck. I’m trying to be in YOUR field because I’d compare the DIY ppl to the presets on garage band ppl vs the pro equipment industrial sound designers are more so like yourself and the field you’re in comparatively. Sorry this is so long and convoluted hahaha. But yeah If you’d like to personally swing me an email of the gear you’d recommend and even chat a bit about our vision here altogether. My email is oqulomusic@gmail.com
And my music if your curious to listen to the progression over the years is
Sounscloud.com/harrymeds
My vision for this company goes parallel with my music and involvement with the industry where this type of work compliments that and back and forth while also catering to different demographics altogether as well. So thanks for your time, hope to hear from you soon. There’s no money to be made as a DIYer preset using hobbiest. It’s all about the industry baby!! Thanks!
Nope, but all the videos have links to all the products used in them in the description.
