Cobra Steve Report post Posted November 22, 2009 what is the best thread size to use on a 29k62 and what is the heaviest thread this machine can run . Hi alberta, the best sizes of thread for the 29 class machines is # 46, #69, #92, and in some cases #138. These are the bonded nylon sizes, which in my opinion, is the best thread for sewing leather. Thanks, Steve Quote Share this post Link to post Share on other sites
