Technical Information

Quick Fixes

• If you are experiencing tension problems, looping, or pin dotting, we know this sounds weird, but the first thing you would want to do is re-thread your Gammill sewing machine to ensure proper threading.  A simple re-threading of the machine often corrects many tension issues.

Common Causes for Vibrations

• Tight spot in head.  Turn machine very slowly by hand to verify.
• Rubber axle grommets too hard or too tight.  Replace with blue rubber grommet tightened only hand tight.
• Front wheels not supporting weight equally.  Use eccentric in axle to adjust.
• Operator running machine at speed range that produces harmonic vibration.
• Needle bar guide cylinder not getting oil.
• Pattern board not secured.  Place small strip of batting on board support to cushion.

Common Causes for Thread Breakage and/or Thread Fraying

• The most common cause for thread breakage and fraying is the poor quality or weak thread.

• The second most leading cause the Improper threading of Gammill quilting machine.

• Check to ensure you do not have an Improperly installed needle and...

• The installed needle is not too small for thread being used.

• Make sure there is no damage to a thread handling part, like thread guides, tension springs and the tension mechanisms.

• Check to make sure the needle bar is not too high or too low.

• The Sewing mechanism could be out of time with needle.  Contact us if you need assistance with this.

• The sewing hook point is too far from the needle.  This again is a timing issue as well.

• You could have a Bent or blunt needle.

• The hopping foot (or presser foot) is set too high, thus allowing flagging of fabric.

• The hopping foot could also be out of time with needle.

• A common, but sneaky error, could be the Pick-up roller is set too high.  Ensure proper distance between the pick-up roller and the base of the sewing machine.

Threading Hints

• Use tweezers to grab the thread while threading in tight, hard to reach areas.

Things to Check

• Make sure you thoroughly oil your machine at the end of the quilting day.  Remember, the hook assembly requires one drop of oil about every 2 times you oil the machine.

Threading Changes

 The Gammill technicians and professionals have determined that we need to revise our threading instructions slightly.  The changes are minor, but very important to ensure proper thread tension.  

FOR THE PLUS Systems:  

Instead of threading the thread lead-off from top to bottom in the rear thread guide, as we have been doing, we should instead thread this guide from bottom to top, but wrap the thread around the thread sensor wheel TWICE instead of just once.  (The second wrap will provide enough tension to grip and turn the wheel properly.)

FOR THE CONVENTIONAL Systems:
