What 29K Is Best?

[mikesmith648]

Found a 29k51 and a 29k70. Which one is best for sewing leather?

[Wizcrafts]

The best machine is the one with the least slack in the feed and shuttle mechanisms. So much depends on tight clearances, especially in the ring in which the foot revolves. If the puck shaped actuator is worn down, the machine won't produce long stitches at any thickness.

Aside from the wear factor, They are both short arm patchers with small bobbins and are best suited to #69 bonded nylon thread. The maximum thickness that can be sewn is about 1/4 inch. The stitch length diminishes with thickness, so a machine that sews 5 to the inch at 6 ounces may only yield 7 to the inch at 1/4 inch of leather. A worn machine may not even sew 7 to the inch into thin leather.

I would recommend taking some pieces of 8 ounce leather with you and see if one machine gives longer stitches at 1/4 inch. Then make sure it actually sews a proper stitch. Some old Singer patchers have missing, broken or bent thread check springs and skip stitches no matter what else you do.

I don't know what kind of leather projects you anticipate sewing with these machines. Don't expect them to sew holsters, or rifle slings. They are made for soft to medium leather, from 4 ounces up to 16 ounces total. They are meant for repairing shoes, boots, and for sewing patches onto garments.

Well that fixes that idea. What kind of "inexpensive" machine would do refle slings and holsters as that is where I am leaning towards?

How much would one of these cost? And how thick will it sew?

Please define what you consider "inexpensive."

Next, state the size of thread you want to use mot of the time and the probable thickness you intend to sew.

I can sew rifle slings all day on my flat bed walking foot machine, using #138 thread.

Holsters are another story. A properly sewn serious use holster has #277 thread or even #346. No standard upholstery grade machine can properly handle or tension those thread sizes. You'll need a machine like Busted described (a.k.a: 441 clone, like Cowboy, Cobra and Techsew), or a Union Lockstitch needle and awl machine, like I use.

Hey Wizcrafts, there is a 47w66 on ebay for sale in Texas. Would this do for what he wants?

It will sew around 3/4" to 7/8" material. They cost around 2300 with all the tax and shipping and what ever else you might need.

I hate to cut in here but the 47w66 is a fairly light duty machine max thread size #92 maybe can sew5/16" thick.

I am trying to stay under 1000.00. probable wont sew over 3/8" and if I do I would probably outsource it to someone who really knows what they are doing and has the machine to do it with. That is why I was thinking of the 29k. Not really sure as this is a new aveue for me. All I have ever done in the past is handstitch.
