Well, the limit appears to be somewhere between 11.5 to 12.5... and that's a limit that looks to ME like it's a combination of the FRAME and the machine... you wouldn't (I think) have that far with the 13" Bailey - if somebody has a 13" and knows for sure, they can jump in here and let us know...
the top two bars at full extention (shown in machine1 picture) are 15" apart -
I have 4 yards of flannel rolled on both front rollers (12 feet) so not a teeny amount :lol:
from bar to bar -15" machine travels the full distance
showing the carriage the machine rides on
needle as far forward as it will go because of front bar and 'carriage'
