Okay this is great advice. I did end up adjusting needle bar height a recently so maybe I adjusted it off a tiny tiny bit. Thanks for the tips!!!

Do you have any ideas on why the top thread was slipping down along the outside of the bobbin case? All the sewing frustration aside, I was worried that I had messed up my machine. The sound does bother me but more importantly I was worried that this sound was related to why the thread kept falling getting caught alongside the bobbin case. I only have 1 spool of thread (tex69 and I'm using an 18 needle) so when I loaded a bobbin I would go full speed and max out the revolutions to fill up the bobbin quickly. After doing this like the 3rd time then this loud metal clacking sound developed.

Thanks Wizcrafts! Just to make sure I'm following you....the purple/yellow circle is the opener arm. That needs to slide forward just a hair. The purple circle is the screw where I could bring the arm forward.

Bravo that looks amazing

This video might show the sound I'm talking about a little better. PXL_20210120_001546704 (1).mp4

Hello amazing leather workers and sewists! I need some help figuring out what going on with my beloved Juki. I'm 2/3 finished reupholstering a sofa and I started having issues with top thread getting stuck outside around the bobbin case. Thought it was just thread tension issue, but then this clacking / grinding sounds developed. I oil everything regularly and also oil around the bobbin case. I took out the bobbin from the bobbin case to look for jammed threads....nothing there it seems to be nice and clean. When investigating I noticed that the whole bobbin case assembly seems to have a significant amount of play. Like something is loose but I can't figure out what. Any help would be super appreciated. Thanks! hook (1).mp4

**update on the skipped stitches situation. I took Northmount’s advice and went back to the basics. I mentioned earlier that I bought this machine in rough shape. The table it came on was broken from a move, so I had to make a new table. After setting up the machine on my new table, I noticed the fit wasn’t perfect but figured it wouldn’t matter too much. well before messing with the settings on my machine, I decided to put shims in the spaces where there were gaps between the table and the machine head. Now the machine sits really snug and doesn’t not move or vibrate at all while running. And....no more skipped stitches. Another factor is that the fly wheel is a little bent so the machine rocks a bit from that wobble. Maybe that was contributing to the problems I was having. I tried to straighten the shaft by taking off the flywheel, using a pipe, and attempting to bend the shaft. I had no success with that. Anyway, the journey continues, and I can finally start working on projects again. pic shows gap , now I have this space fitting more snug using shims

Yes I will take some pictures today. I haven’t made any progress on it, so I plan to get back tot the basics and start from scratch with the whole process. I’ll post more pics this afternoon

So, I messed around with hook placement and needle height some more. Still lots of skipped stitches. Ugh. Feeling pretty frustrated since I spent a few days getting the hook timing and rotation set up correctly. I must be just a hair off. Has anyone experienced this problem before? And do you think just tiny little adjustments to the hook/needle height can make a dramatic difference in how the machine stitches. I definitely notice that skipped stitches tend to happen more when I'm running the machine fast I bought this machine used, and it came in rough shape. It had stitching problems since the first time I tried it out. I have switched up a bunch of different needle size and thread size combinations, as well as top thread tension. Still skipping stitches.

Here’s a pic of the clutch

Just a test

Thanks for the tips with the photos. I do most of my posting with My iPad but the forum doesn’t allow for me to upload the photos because file size is too big. Any tips for downsizing photos on an iPad? I try out hook timing and hopefully that will solve the skipped stitches **edit. Got photo uploading figured out!

Hello, I am reaching out for help again. I got my machine working now! Very excited about that. I ran into some trouble with skipped stitches. I put a new size 18 needle in with TEX69 thread. I messed around with tension alot which didn't seem to affect the skipped stitches. Here's a photo to see a sample. I did different stitch lengths and that seemed to help just a little bit. Smaller length stitch = less skipped stitches. Any tips to get my machine stitching every time? Thanks!

I was able to get the machine stitching beautifully. Thanks all once again. I have another question about my safety clutch on my machine. I noticed mine doesn't have a spring and if I want to engage the clutch I have to use a screw driver to force the clip down into the groove. My question is, do I need to buy a whole new clutch or can I just buy that little finger and spring? I found some springs on ebay but no luck with the finger. Link shows what my safety clutch looks like now. https://photos.app.goo.gl/mC9RSFmaMTb1G7J78

Thanks y’all. I’m working on it again today and will report back. cheers
