Hi, I want to use some thick thread (size 554 polyester) which is 0.8 mm in diameter. The standard stitching groover makes a channel that is barely that wide and with a few passes, I can get it deep enough to stuff the thread in. What I find, however, is that the awl piercing extends beyond the groove when rotated to the correct angle: I could rotate the awl clockwise from what the diagram shows, but the piercings would then come close to lining up. A smaller awl would make it very difficult to pass the needle through. Regardless, there is not really enough room in the groove for the stitches to lie properly. Is there a wider cutter I should use or should I resort to making a wider groove with two parallel passes? Thanks in advance!
