Memphis514 Report post 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 Share this post Link to post Share on other sites
Wizcrafts Report post 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.

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. Quote Share this post Link to post Share on other sites

Well I'll be damned the #25 worked flawlessly...thank you Quote Share this post Link to post Share on other sites
