rickmenefee Report post Posted August 24, 2012 I have a 205 adler that i have been useing without a glitch. I changed motor today to a variable speed. Its like a whole new world. My problem is the stich is setting on the top side of the leather know. It appears the bobbin is not pulling the thread tight enough to pull the loop down between the leather. I am sewing 3/8 thick leather for knife sheaths. Any help ? Quote Share this post Link to post Share on other sites

Ferg Report post Posted August 25, 2012 Sounds as tho- you need to readjust your tensions. Loosen top tension a little each time you test. If two or three changes doesn't appear to help, you will need to increase tension on the bobbin. If you do not know how to do that someone on here will help. ferg 1345852215[/url]' post='261675']I have a 205 adler that i have been useing without a glitch.

Wizcrafts Report post Posted August 25, 2012 I have a 205 adler that i have been useing without a glitch. I changed motor today to a variable speed. Its like a whole new world. My problem is the stich is setting on the top side of the leather know. It appears the bobbin is not pulling the thread tight enough to pull the loop down between the leather. I am sewing 3/8 thick leather for knife sheaths. Any help ? Three causes come to mind: The top thread is caught in a guide, post, or stud along the path to the needle. The needle is way too large for the thread combination and is making too big of a hole. The bobbin thread has slipped out from the output guide in the bobbin case and has little or no tension.

KAYAK45 Report post Posted August 25, 2012 Just changing out a motor should never effect the stitch the machine was making before the switch. Something else changed. Start w/Wiz idea and trace all the obvious. One other thought. Do you now have the correct length drive belt? My change-over required ~1" less belt. Maybe? .. you are having a slippage problem??? Good luck, and when fixed you will love the Servo. Kevin Quote Share this post Link to post Share on other sites

rickmenefee Report post Posted August 25, 2012 I think the problem was the belt was to tight. Know i have missed with it so much i really have a problem. Quote Share this post Link to post Share on other sites
acowboy Report post Posted August 26, 2012 a motor change or belt tension doesnt have anything to do with your thread tensions...youre looking in the wrong place... id check my top thread back to the spool looking for a bind...you may have knocked something out of whack working on the motor Quote Share this post Link to post Share on other sites
