Members blueblade3000 Posted October 13, 2018 Members Report Posted October 13, 2018 (edited) I'm working on my first leather project, a pair of Jorvik turnshoes. I found a few tutorials online and feel like I understand the technique, but I ran into an issue with execution. I'm trying what one tutorial refers to as an "edge-flesh" stitch, stitching through the flesh side and coming out of the edge at an angle. This is with veg tan sole bend from Tandy Leather. The problem is that the sole bend is tearing very easily, sort of separating and losing its integrity. I think one problem might be that my stitch holes are too close together at about 1/8 of an inch. But even after punching the awl through the first hole, I could see the problem. What am I doing wrong or what can remedy this? Should I wet or oil the leather? Edited October 13, 2018 by blueblade3000 Quote

Contributing Member fredk Posted October 13, 2018 Contributing Member Report Posted October 13, 2018 a. your leather is too soft b. the leather is too thin for your thread and stitches. Thread and hole should be no more that 1/4 thickness of the leather for going via the edge Quote Al speling misteaks aer all mi own werk..
Members Matt S Posted October 13, 2018 Members Report Posted October 13, 2018 I've never made shoes but soling bend that tears? That doesnt sound like the soling leather I've handled or used. I suspect either the leather is substandard or you're pounding a very blunt awl through the stuff. Quote
Members blueblade3000 Posted October 13, 2018 Author Members Report Posted October 13, 2018 I can't upload a picture right now as I'd have to reduce the quality due to permissions, and I don't know how to do that on my phone. The leather is 1/4 inch thick, but one of the needles I'm using has a "spoon shaped" flat section that's over 1/16. I suspect that's my mistake. As far as sole bend tearing, on a test piece, if I pierce through, it pretty easily tears if I try. A little twist of the awl will do it. Is that abnormal? Quote

I suspect that's my mistake. I never did grain - edge on shoes, only on knife sheaths. I used a thin parallel sided diamond section curved awl to make the holes and a thin curved saddlers needle to sew 55 minutes ago, blueblade3000 said: As far as sole bend tearing, on a test piece, if I pierce through, it pretty easily tears if I try.

Members Aven Posted October 13, 2018 Members Report Posted October 13, 2018 (edited) Blueblade, using an awl to make your holes first may help. You need to use a curved awl. Start about 3/8 back from the edge. Start the hole go in about a third and kinda pivot the awl so it slides along the blade curve and aim to come out about 2/3rds down from the top edge. It's easier to do the holes before hand. This is a picture of a curved awl that Jason Horvatter from Laughing Crowe sells. Jason also teaches shoe making. One of the styles he teaches is a turnshoe. If you can't get to one of his classes, check out the turnshoe video he did. Well worth the price. Edited October 13, 2018 by Aven Quote

Members blueblade3000 Posted October 13, 2018 Author Members Report Posted October 13, 2018 The sole itself did not tear through, but it seems to want to separate like flaky pastry. And I think a couple of the holes joined together as the thread "cut" through, but I couldn't tell for sure. Quote
Members Aven Posted October 13, 2018 Members Report Posted October 13, 2018 That sole leather looks thick, but not compressed like it should for a sole bend. I'm seeing some shallow holes. It's easy to go too shallow and rip through. My stitches are spaced about 3/8" apart. Quote
