Members Instinctive Posted March 4, 2017 Members Report Posted March 4, 2017 I use really good 3/32" lacing chisels to punch holes from both sides to meet in the middle. I have been consistently able to do this with very good results with a total thickness up to 30oz. My process is: Everything is glued first and clamped over night. Sand the edged with a drum sander. Groove both sides 3/16" from the edge. Use a 1, 2 and 3 prong 3/32 chisel set to punch holes down one side. Use a stitching awl to punch through the first start point hole for the back side and then punch the holes on the back side. I use .045 (1.1mm) thread to saddle stitch. I keep the awl handy to open any holes that may need it. Slow, patent chisel work is key to making this work. This is a typical result.

You'll end up making an 'X' instead of a '/' at each hole. But I really like the idea. You could punch from one side with the stitching chisel, use the awl to identify the start point, mark (not punch) the back then use a thin scratch awl from the back to open the holes and provide a path of least resistance for the awl as you sew. I know it's a lot of work and I should just learn to use the awl properly but this might aid in developing good technique. Quote

That right but a lacing chisel gives you a '-' and I find that works perfectly with this heavy leather. You don't need a '/'. See my next post.

Here is a picture of the chisel and a sample piece I was recently playing with. Holes are chiseled on the back exactly the same way. In this case I was opening the hole a bit with a thin round awl after both sides were punched. Total leather thickness is 12mm. My chisel tines are 8mm long.

Members battlemunky Posted March 5, 2017 Author Members Report Posted March 5, 2017 Thanks for the responses everybody. Not only good advice but some good discussion in general. I have several different types of chisels, / and |, along with both round awl and diamond awl, and a dremel and bit but I pretty much left that behind opting for chisels and awls. I guess I need to keep on practicing, slow down, and be patient with all the methods. I also have the overstitch wheel too which I use to mainly set my spacing evenly. Quote
