I am using the 88044 2mm chisels. I have the 2,4,and 6 hole punches. They work good with bigger thread. My issue is the back. I punched the holes in the outside before I assembled it and then used a diamond point awl to punch the gusset after it was assembled. I have never been able to make the backside look descent. Always crooked. The sewing machine is a least straight on the back side. Do you put a stitching channel in the back side? The only time I did that I missed the channel a little in places and it really looked like hammered crap. Maybe a little practice would go a long way. I was just at Tandy and looked at the fine diamond chisels but 7 spi are to small for me. I usually machine sew everything 5 spi with 138 or 207 thread. Mostly small stuff. Thanks Tim
Here is a picture of the only really bad spot, the rest is acceptable. This drives me crazy.
