Touch & Sew 620 timing problem
Hi everyone, hope you can offer some suggestions for my Touch & Sew 620 problem. The timing keeping going out. Here is the history:
Oct. 2008 - I was trying to edge a very fine piece of fabric like chiffon but just couldn't get it right. A friend suggested I try putting in rubber feed dogs. Not being one to mess with my machine, I thought it sounded like a simple project and I would try. So I took out the metal fed dogs just to see how hard it would be. Easy enough...so I put them back in until I could order the rubber ones. Never did...but ever since then the machiine started to skip stitches. I took it to out local VacWay for repairs in Dec.
Here is what they did:
reset needle bar
adjust feed dog timing
adjust hood timing
It has never worked well since. I had it back four times and each time the guy would adjust the timing.
I'd only get about an hour out of it and it would be off again. I find that it will not sew over thicker seams without going out of time. I was sewing doll clothes for my granddaughter. A piece of stretch denium was the first culprit. The thicker seam would not go through the needle..the needle would just sew in the same place. then it was out of time, I could hear the needle hitting on the bobbin or something underneath. Back to the shop.
Reset. Now I am sewing on T shirt fabric and the machine will not start at the end of the seam. This fabric is not that heavy for it not to handle it. It just again would not go through. And again, it is out of time. This time it won't even pick up the bobbin thread.
So I'm convinced that I may have messed it up taking the feed dogs out. Even though the guy adjusted the feed dog timing it just won't work for double seams. Is there something I can do myself or do I have to take it back to the shop? This is why I never tinkered with my machines in the past.
Oh, and the worse thing is...I pulled out my Athena which I haven't used in over a yr. and lo and behold it too skips stitches. It never fails. Whenever I have projects to complete something goes wrong.
Thanks for listening to my sad story. Anyone have any suggestions.
I think I may have to try another repair shop and pay another $100 to have it fixed. Hope not. Kathie
