I bought this machine a few months ago and started “to sew” 2 weeks ago...
yep not happening, why?
Help help help!
Hook issue.
Falcon 269 FN1 cylinder bed - (Adler 267/373) - (Techsew 2750)
current issue: hook-shuttle binding
“hook” picks up thread, but thread doesn’t seat in the ‘groove’ behind the hook & goes passed the groove causing ‘Timing’ of pickup bar to begin upward stitch lock- “popping” thread around bobbin carriage causing a residual loop that the second hook rotation catches, birds nest, miss or sometimes (rarely) a complete stitch. (But never next cycle)
what I see is that the thread needs a certain angle/distance to catch the ‘loop around’ groove that is too wide (too far from dog-foot-plate needle hole to successfully catch the loop around after the hook pickup) the angle it seems to need, requires the needle to be nearly out of the needle hole up, but at the same time the rotation distance of hook-loop-around vs highest successful hook catch meeting is still nearly 7mm shy with no “obvious” adjustments.
things Ive tried: centering walking feet to zero, moved the hook assembly closer, 0.1 mm (yep), backing the timing all the way till the hook meets 0.15mm above eyelet (loop) & bottom of scarf; as well forwarding the timing until the hook touches the top of the scarf.
since my machine is a Falcon FN1 296, the timing seems to be only adjustable from the main pulley (transfer belt/safety clutch) because the rod connecting to the hook drive gear has a groove cut into it on the “A-Typical” adjusting area, which only seem to be able to adjust horizontally on the center rod (rotates continually)
what am I missing???
(please tell me correct terminology)
thanks in advance for reading and giving your opinion, suggestion!
Hours logged so far 32... very embarrassing, I’ve swapped motors out in less time...
