91bird

I dug deeper into the material specs. Type 13 webbing is 2.90 oz per yard. 0.080-0.120 inch thick. Not sure how to classify its temper. Seems to be a material at the minimum material density of a CB4500 and the top end of thread capability of a Juki 1541 when using #138.

Thank you. Looks like a CB4500 would be a better choice than a Juki 1541 for making belts and slings out of webbing and leather.

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?

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.

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.

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.

I'm also noticing machines from the vintage of 206RB-1 and 206RB-2 are grey color. Where might I find the Seiko embossed on the bed? I can have the seller send a pic of the area.

Am I looking at a real 206RB? Overall picture of the machine.

I'm looking at purchasing a used machine, claimed to be a 206RB. I'm questioning if it is really a 206RB? Or a clone?? The logo on the front of the machine is rectangular. From pictures online the Consew logo is oval. Also the label with model number looks very different from the Consew label I'm able to see from 206RB machines on the internet. Font looks different, doesn't say made in Japan as I would assume a machine from this vintage would say. From machines on the internet, I would expect the Consew label to be oval. The ID tag from the internet is below as well.
