I think I'm closer to solving the vibration issue - I made an adjustment to the front wheels on the machine after speaking to a woman at the Gammill booth which made it a LOT worse. This was a good thing however because it let me know I was on the right path. I made a second adjustment and the vibration is better but still there. I know it's something that occurred during the move because it wasn't there before so I'm hoping with some more tweaking I can get it back to pre-move condition.
Can you see the white clamps in this next photo? This quilt belongs to Kathy, a member of HeartStrings and this morning when I was struggling to get it positioned for quilting - I decided to try out these new clamps from Tomorrow's Heirlooms that I bought at MQS. I usually only do a full float on my really small donation quilts (crib size) and do a partial float on all the others. Who knows, after this I may start doing full floats on all of them.
Here's a peak at the quilting - it's a pantograph called Plumage from Willow Leaf Studio.
