Contributing Member JLSleather Posted March 24, 2017 Contributing Member Report Posted March 24, 2017 So the "fix" for a bushing with too much "play" is to "one-side" it in the hole? Okay ...

Members brmax Posted March 24, 2017 Members Report Posted March 24, 2017 (edited) Its dry. It may be possible to remove the top presser spring retainer nut totally. In doing this a better oiling of these parts surely could be tried. This seems to be a new machine fit type issue though a pain i think a bit of time and youll be off n stitching. I had earlier tried myself manually lifting the presser foot on mine at its mount point and this is handy. Have a good weekend Floyd edit: oh the ole chatter roller ya!

Okay ... Yeah - I am not sure, it did stop it from skipping. My guess is that when the outer foot is going up, the inner foot is pushing down - and due to how the linkage is set up there must be some lateral force on the outer foot bar with the spring. Both feet use that same spring for tension, so the inner foot looks like the lateral force is counteracted by applying equal force using the bushing against the wall. Without enough pressure on the bushing plate, the rod probably bends ever so slightly. Same with too much pressure is my guess as well. Quote
Uwe Posted March 24, 2017 Report Posted March 24, 2017 (edited) I think the vertical plate adjustment is just a normal adjustment for this machine's design and does not indicate a loose bushing or some other defect. The bearing wheel presses against the vertical surface as it rolls up and down. That vertical surface needs to be in the right plane to keep things aligned properly and provide a leverage surface for the bearing wheel. If the vertical surface is too far away the linkages put horizontal pressure on the presser foot bar and deflect it or press it sideways against the upper and lower bushing walls, rather than guide it straight up and down without sideways deflection or pressure.

Members brmax Posted March 24, 2017 Members Report Posted March 24, 2017 Thats what gets my goat, i got all worked up on mine and so got ready. Did work outs! Push ups everything. Even brang all the tools in, a new pot of coffee. I made the call and like : do this, i did and it was fixed and done. Dam coffee in my cup was still steaming. Floyd Quote
Contributing Member JLSleather Posted March 24, 2017 Contributing Member Report Posted March 24, 2017 From the video, I'm thinking that the noise (which is more obvious when you slow the video down to 1/4 speed) is from the SPRING contacting teh casting in the low end. "One-siding" the shaft in the busing wouldn't be my first "plan", but .. If the shaft is off by that noticeable amount, a guy might think about an eccentric bushing to allow it to pull back in the right place. Question is, does it look like the needle itself is moving laterally with each stitch? Quote "Observation is 9/10 of the law."

Uwe Posted March 24, 2017 Report Posted March 24, 2017 I vote for letting the man enjoy his stutter-free machine. Quote Uwe (pronounced "OOH-vuh" ) Links: Videos
Members JREESER1 Posted March 24, 2017 Members Report Posted March 24, 2017 I second that motion, Uwe! If he is happy with the fix, that should be all that matters. jr Quote
Members MrLentz Posted March 24, 2017 Author Members Report Posted March 24, 2017 haha, well as long as it is not a patch for a bigger problem i'm fine with it! Quote
Uwe Posted March 24, 2017 Report Posted March 24, 2017 I really do think the fix was a normal adjustment and I don't see any indication of some major flaw that needs to be worried about. Quote Uwe (pronounced "OOH-vuh" ) Links: Videos
