This is the first time I’ve heard of the “bobbin drop” technique. I’ve never known how to determine what was a reasonable tension on the bottom thread so I found this very helpful. Thanks!
Hi Harry, I just wanted to give you an update on my tension problem. My problem was, on my JUKI, after tightening the tension on top dial quite a lot, the stitch was fine on top and on the bottom, BUT anymost exactly every 6 inches, there was one stitch on the top that had a raised visible knot and that was one stitch almost exactly every 6 inches. After about 100 hours, playing around with it, including checking play on my pressor foot knee pad, I found out that 'I was using a needle that was 3 sizes larger' than the correct needle for thread (as per needle thread chart). I changed the needle to correct size, loosen the top tension and it stitches fantastic.
As always, Brilliant that you're providing us with such valuable advice ! Before seeing this, I was just blindly experimenting to try and get the stitches looking right. Even worse, they'd start right and then disintegrate. Now I have a full understanding of how to check everything ! In my case, I can't do a bobbin drop, as I have a flying shuttle - but everything else you've covered is so useful ! Thank you !
Great tips Harry! I started a TH-cam channel called Right On with Jon Crane. I mentioned you and put in a link to your channel in my first video as you are an inspiration! Thanks for all that you share on TH-cam!✨🏆👍🏼🙏🏼✨✨✨✨✨
Thanks Harry, much appreciated. I was having a bit of tension issues on my CB6900. Twiddled the top tension knob and now (so far, so good) it has been resolved. Thanks for sharing this tip.
Glad I've found your video, I've been an orthopedic shoemaker for about 12 years now and I've suddenly felt the urge of branching out into learning more about leather work. We have a fantastic in-house upper maker who I hope to soon learn the basics of upper making from but since he doesn't use the Singer repair machine (old one, handwheel and footpedal) we have he doesn't care to adjust it properly, which sucks for me cause I occasionally have to use it. Now I have a better idea of how to do just that!
You’ve just answered my prayer my good sir.. I’ve been trying to figure out and been asking people why I keep getting loops under my work. Thank you very much
Thank you Harry. Everything you said fits with my experience. This video was as excellent. The only problem with it is that I had a case of absolute envy when I saw your sewing machine. Good for you that you were able to justify getting one. I have no doubt that you use it at it's full potential - that would not be my case. I am looking forward to the next video.
Thank you, Harry. Just getting my first industrial up and running (a 331K) and have been having heaps of tension problems. The bobbin drop test uncovered mine was way too tight. Damn good channel. Regards from Arizona.
Thank you this helped. Anither question i have an Artisan 794 Toro 3000 leather machine and it was seeing just fine yesterday now today it wont pick up the thread ive tried all i know but it still wont pick up the thread in the bobbin area. Any ideas. Thanks
Excellent as always. I noticed you seem to have a variable speed motor, my Juki with a digital motor has a fixed speed peddle and controller, can you tell me you what have done please?
Hi its a variable speed Jack Servo but I have also geared it down with pulleys and there are a couple of films on this in the Leatherwork playlist. Rgds Harry
Hello, thanks so much for the tips. Question: does it matter if the bobbin is full or it doesn’t matter. Just thinking the bobbin can weigh a little more if full during the drop test. Thanks
This is great advice as usual, but, I use a cowboy 3200 (Hightex 3200 in the UK), and as far as I am aware cannot do a bobbin drop test like you demonstrated, as the bobbin holder does not detach from the machine like it did on your Juki, do you know if it's possible to do this type of test on my machine some other way, or do I have to just keep altering the screw tension and hope for the best so to speak?
Hi Peter...hopefully someone here knows, but I am guessing you could tie another bobbin to the end of the existing bobbin thread in your machind and see how much tension is on it by then dropping the spare bobbin.
I have no room for a dedicated table for a leather sewing machine. I was looking at the Sail Rite machines. 'Portable', in a case. Have you heard about these machines? Plus, way off topic, what does a conscientious leather worker do with leather scraps. Too small to make anything. Can leather be 'recycled'? I have never been able to find out. I know it will degrade eventually. Thanks Harry.
Hi I have never used a Sailright but I believe they are pretty sturdy machines....I guess there are reviews on here somewhere or someone can advise. I was wondering about doing a patchwork or leather animal with my offcuts.

Harry Rogers thanks. Looks really good quality and much better than the generic Juki clone I bought. I may have to change to a real one. Love the bobbin drop test btw.
@@harryrogers When I say bottom I don’t mean a loop from the top thread poking through. I mean the entire bottom thread appears to be loose. Could it be a take up lever issue?

I really admire everyone who makes and/or fixes things. And, people who make vids about it are amazing.

You are amazing. Thank you for sharing this. Even the small tips are great! Lovely showing voice. Very soothing.
Boy could I have used this video two weeks ago, lol. Great video!
Thanks Dave. Rgds Harry

Thank you Harry. I am learning so much from you.
Very handy little tutorial. Thank you
Thank you for sharing such valuable information Sir
Learnt something new,thanks
You saved my life thank you
Yes, Very Helpful advice...Thank you Harry

Thanks Thomas that's great to hear...nice machine.
Just picked up a 331k5!
I don't suppose either of you have an operating manual for that series?
I can't find one anywhere so far!!
Very useful information! thank you!
Thank you profusely!!!!!
it solved my problem...no one else mentions the bobbin drop test.
Very useful / helpful information, thank you.
Thanks Harry, very informative.
Thank you so much i have learn from you.
Awesome video. Ty!
Big Thanks 🙏🏼
Thank you!
I also use the drop test, pretty much the same, it should hold when steady but move if you jiggle it about.
Thank you Harry
wow...very helpful..thank you!
Thank you Harry and Happy New Year
Thanks for the video .
Hi Harry! Thanks for the useful info. I have an old Juki 241H. Where did you get that nice set of feet, on the left hand side only? Thanks!
Hi it was probably Ebay or College Sewing Machines
Thank you this helped. Anither question i have an Artisan 794 Toro 3000 leather machine and it was seeing just fine yesterday now today it wont pick up the thread ive tried all i know but it still wont pick up the thread in the bobbin area. Any ideas. Thanks
I would change the needle, check the thread run and rewind a fresh bobbin....Good luck.
Awesome! Thanks.

I have this machine ,Jack 8720 , and can I saw leather on it?.....I have tried but couldn't...
Hello, thanks so much for the tips. Question: does it matter if the bobbin is full or it doesn’t matter. Just thinking the bobbin can weigh a little more if full during the drop test. Thanks
No.
Interesting point, but I don't think it matters as most bobbin cases are relatively heavy compared to the thread inside. Rgds Harry
Harry, what about if the stitch tension looks fine, but you feel the stitches look too loose? Perhaps too big a needle or something?
Yes and you can tighten both lower and top tension equally.
This is great advice as usual, but, I use a cowboy 3200 (Hightex 3200 in the UK), and as far as I am aware cannot do a bobbin drop test like you demonstrated, as the bobbin holder does not detach from the machine like it did on your Juki, do you know if it's possible to do this type of test on my machine some other way, or do I have to just keep altering the screw tension and hope for the best so to speak?

Harry is that a Juki 1508 or 1541 machine?
Hi David it's a 1541.
Harry Rogers thanks. Looks really good quality and much better than the generic Juki clone I bought. I may have to change to a real one.
Love the bobbin drop test btw.
What about a loose bottom stitch?
Hi increase top tension...
@@harryrogers When I say bottom I don’t mean a loop from the top thread poking through. I mean the entire bottom thread appears to be loose. Could it be a take up lever issue?
@@chandlersanders Correct needle size?
@@harryrogers yes sir. 138 thread with a 21 needle.
