Jeff;

The Juki LU-1508N uses the standard system 135x16 (leather) needles and can sew about 3/8 of an inch of compressed material with #138 thread. The LU-1508NH uses a longer Pfaff needle system: 190. These needles are about 3/16 inch longer than standard walking foot needles. Since the shuttle hook is still in the same vertical plane, the needle bar is raised up the 3/16" to keep the needle's eye in time. This also allows the presser feet to raise and alternate higher before they contact the bottom of the needle bar. The difference is that the class NH can sew between 7/16 and 1/2 inch of material. Also, changes to the shuttle allow it to carry #207 thread in the bobbin as well as on top. The list price is somewhere in the mid 3k range.

As for heavy duty cylinder arm walking foot machines, I use the Cowboy CB4500, which has a 16 1/2 inch arm, uses up to #415 bonded thread and sews up to 7/8 inch of leather. It comes on a pedestal table with a powerful servo motor and a 3:1 speed reducer. It can sew extremely slowly (well under 1 per second), up to maybe 5 stitches per second, flat out.

This was super helpful. I’m considering this machine for bag/wallet/belt making. I want and Adler but that just too pricey at the moment, the Juki looks like it too could get the job done. Thx!

I think it would be good in 1508 NH discussion ( along with many 190 sys. others ), to ask others what leather point can be used that best can hide, a need using a bigger needle. 

Im first saying this because I like 190 system. In respect lets assume or I'm saying I aint changin. So with help I think this can be a grest question, and could be called splitting hairs totally!

I would like to key in on a point Wizcraft put in his post; (  This also allows the presser feet to raise and alternate higher before they contact the bottom of the needle bar. ) well said!

Can I also use, This: I think this height benefit is also a running start, or a wind up so to speak.  

Anyway, That contacting the needle bar is a noticeable event in really hard to repeat sewing scenarios. Like while simultaneously turning material, twisting to raise it and possibly using the knee bumper with extra thick paddings etc. etc. 

To my knowledge and usage this 190 system is optional to use on both the 1508 and 1541 series if desired. But as a known the longer anything in the same diameter the more flex it may have. 

Hence my question/backstory, bigger diameter needle but better thread hiding cutting tip. 

 

Have a good day
