I had the Juki 98Q back in the early 2000's and had it stretched by a guy down in OK. His health wasn't the greatest back then but he was training someone to take over his practice of stretching machines. He stretched certain Singers, Brothers 1500 and Jukis. Whether the guy he was training is still doing it I can't say and when the machine has been stretched, its not as pretty as they attached a metal plate over the center area to hide where they cut it into 2. But I never had issues with my stretched Juki on a Grace Pro frame and with MQR robotics no less. I sold it when I went to a larger 26" Innova machine. Good luck if you can find someone to stretch your machine.
