I was sewing some today on my DIY saddle using my Necchi Supernova. The Supernova is heavily constructed and has a lot of power but it only has 3/8 inch of presser foot lift. I had a hard time sewing on a section. I thought I sewed on thicker webbing layers before and measured a few of my machines. My Singer 15-91 and my Singer 15 clone has 1/2 inch of presser foot lift. My Japanese Kingston machine from the 1960's has 9/16 inch of lift. A Singer 237 had about 3/8 inch as well. If I measure more I will report. IMHO, the Singer 15 class machine is the best domestic machine for sewing webbing I have tested. The Singer 66 class may be good as well but I don't have any of those so I can't comment.
