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?

Yes, deflection is very possible with extra long, #19 needles in a quarter inch of tight webbing. However, if you use #21 or #22 needles, deflection is less likely. Nobody is going to notice the bigger holes in webbing. Just increase the stitch length to offset the larger holes.

PS: I would recommend using #138 thread in .2 inches of webbing. Then use a #22 or #23 needle which is the right size for this thread.

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.

Yes, the CB4500, or the CB3200 will sew belts and slings all day, every day. Just keep the minimum thickness over 6 or 7 ounces of medium or hard temper materials. I personally keep my sewing on a CB4500 to 8 ounces and up using #138 thread and up.

Note that the standard CB4500 or CB3200 setup includes a 3:1 speed reducer for slow precision sewing on leather. This really slows down the machine to the point you may waste valuable time on long runs in webbing. In that case you can buy an extra long belt, debelt and bypass the reducer and go direct from motor to machine.

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.

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.

In a way, It is kind of like leather. as in soft and hard .
Punching Nylon webbing is same. It Not necessarily how 'thick' a nylon webbing is, ..but It all really depends on just how tight 'dense'  a weave is milled to .
With the Adler 69 . I think you can do it with using 138 and using a type 13 webbing and be GTG with it in 2 layers . the type 13 nylon webbing, is a little softer weave ( not to say loose) but it not as hard to punch threw as some of the other heavier tight weaves of webbing out there .
