Members 91bird Posted December 9, 2020 Members Report Posted December 9, 2020 As I'm trying to come up to speed on thread size, needles, machines, and material my head is spinning. I've found guides showing thread to needle correlation. Is there a correlation of thread size to material thickness? I'm going to be starting with making belts out of 2 layers of Type 13 nylon webbing, each layer 0.1 inches thick. Then move into leather belts up to 1/4 thick. I've not found a good guide of thread thickness to material thickness that would drive a sewing machine selection. Any help would be greatly appreciated. Quote
Members Kcstott Posted December 9, 2020 Members Report Posted December 9, 2020 I've never seen anything referencing thread size to material thickness unless it was concerning breaking strength. doesn't mean it don't exist. My advice on belts is, Do you want to see the stitches or not? if you do then the bigger the thread the better. if you don't then a #96 or 138 Polyester thread for UV resistance. Quote

Running different sizes of thread on your Nylon webbing for a Belt, is going make it less stiff or make more ridged depending on thread size. When your wearing and breaking the belt in to you body. Running heavy thicker thread and highs tension over time It will stay stiff ridged longer . I just did up a new 1.75" wide, 2-layers of type-13 a couple days ago for myself . Nylon heavy square weave webbing for belt, I usually just use 69 for just putting it together . If it a Belt for daily carry and adding stiffness rigidness. I run #207 or 277 down both side and two straight runs down the inside . For making less ridged and more softer after the break-in wear, then use 138 or go smaller size thread . Instead of just straight runs, you can trick it up a little bit also and do things like Diamond pattern and things down the center area in different color tones. . Quote
Members chrisash Posted December 10, 2020 Members Report Posted December 10, 2020 Often its the design that takes presidence over strength on leather made goods, a seam made with 69 bonded nylon is very hard to break as the pressure is across the whole seam rather than a single stitch. on other items strength is more important than design Quote Mi omputer is ot ood at speeling , it's not me
Members sandmanred Posted December 10, 2020 Members Report Posted December 10, 2020 What machine do you have? That's a factor in choosing thread and needle as well. Quote Have Consew 255RB-3, Pfaff 545 H4, Chandler 217, Pfaff 138 and Merrow 60W. Had a Singer 132K6, Singer 78-3 Consew 28, Consew 18, Singer 31-15 and regret selling each and every one of them
Members 91bird Posted December 10, 2020 Author Members Report Posted December 10, 2020 I don't have a machine at this point. I'm working to understand what machine I need before purchasing. A Juki 1541S was on my radar, I'm questioning if v138 thread it's enough for my needs. My understanding is V138 is max thread size for the Juki 1541. My needs are to make nylon belts 2 layers ~.2 inches thick with cobra belt buckle and possibly some other buckle options in the future. The use for the belt is competition, range, inner waist band conceal carry, and outer waste band carry. I would also like to expand this idea into leather belts for the same purpose. Quote
Members 91bird Posted December 10, 2020 Author Members Report Posted December 10, 2020 I was able to dig up this thread talking about the same subject matter with a CB4500 using 138 in nylon webbing. 277 thread in leather. https://www.rw-leatherworks.com/blog/2019/03/watch-a-cowboy-cb4500-sewing-with-inline-presser-feet.html#more #69 may be too thin for the type of belts I want to make in nylon, still undecided. Unfortunately I don't have an industrial sewing supplier near me to test out. I'm at the chicken and the egg point needing a machine to do a few test pieces to decide thread size and needing to buy a machine to make the test pieces. 92-277 thread may be the target. Aside from dumbing down the CB4500 for 92 thread, is there another machine that fits better in this thread range? Otherwise it's a Juki1541S to start and a CB4500 later when needed for leather. Quote
DonInReno Posted December 11, 2020 Report Posted December 11, 2020 For the kinds of webbing belts you’re talking about most that I’ve been around are sewn with 138, but it’s very much a design decision. Some webbing with smooth textures might look better with 92 if you are after a sleek look, but I’d still start with 138. When I see webbing sewn with 92 the first thing that comes to mind is they are trying to save money or their machine won’t sew 138. Once you have a big machine you’ll find some webbing looks better with thread larger than 138. Needles are pretty straight forward - use ball nose for fabric or webbing since you don’t want to cut the fibers. There are some good looking cobra-type buckles out there! Quote

This has made me think about my Adler 69. Going through leather I suppose the upper thread limit is #138. Would this be the same on webbing? Never sewn webbing. Quote
Members 91bird Posted December 11, 2020 Author Members Report Posted December 11, 2020 I appreciate the insight given in this thread. When using a CB4500 with #92 thread in Webbing ~0.2 inches total thickness would I have issues with needle deflection and breaking? Quote
