Gregspitz Report post Posted July 17, 2015 wherre the leather got a little thinner on this watch strap the knot pulled tighter to the top and shows... any way to manually fix of hide this any tricks besides not letting it happen in the first place!?..I know I am being picky and obsessive but my customers expect the best job especially on shell cordovan this is shell cordovan with a veg tan backing ..top stitch is 92 bonded nylon red and the bobbin is 46 bonded nylon black using a 18 needle.. Thanks for looking Quote Share this post Link to post Share on other sites
JLSleather Report post Posted July 17, 2015 You can tighten the stitch (down) with a modeling tool (or anything else that wont cut) but it may help avoid it in the future if you step the needle down one size (16) or I would likely bump up the thread size one notch -- 92 top and 69 under.

Gregspitz Report post Posted July 17, 2015 thanks..I always thought from my charts that 18 needle would be good with 92 thread..but looks like 16 with thin leather. and 69 under would make a difference also. Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted July 17, 2015 The needle/thread combination is fine. The machine f-d up. When this happens to me I use the tip of a fine point marker to dot out the knot. Quote Share this post Link to post Share on other sites

Cobra Steve Report post Posted July 17, 2015 If you are using a #46 thread in the bobbin and a #92 thread on top, then I believe that the #46 thread is too small for the hole that the #18 needle punches. You should use a #69 thread in the bobbin which will help fill in the hole. Quote Share this post Link to post Share on other sites
