Members Memphis514 Posted October 4, 2020 Members Report Posted October 4, 2020 ok so i have a CB3200 and on the threadexchange site they say you can run 277 thread through 180/24 and 230/26 needles. what would be the advantage to running this thread through different sizes of needles? TIA, Memphis Quote
Moderator Wizcrafts Posted October 4, 2020 Moderator Report Posted October 4, 2020 I would only use an oversize #230 needle if the bottom of the hole healed up before the knots can be pulled up. This might happen on Biothane harness or heavy webbing straps. For instance, I occasionally get hired to sew vehicle tow straps that are 2 inches wide and about 1/4 to 5/16 inch thick along the overlap. I use #346 thread with a #26 needle to offset the hole bottom closing up. This makes it easier to pull up the knots and center them in extremely dense material.

Expand No. I use a #25 needle with #277 thread. A #24 needle hole is too tight to let the knots come up easily in veg-tan leather. You would have to really crank down the presser foot pressure screw and crank up the top tension, and/or lower the bobbin tension.

Expand Well I'll be damned the #25 worked flawlessly...thank you Quote
