Members davehorseblanket Posted December 25, 2017 Members Report Posted December 25, 2017 I know of a sunstar km-380 cylinder arm machine, has anyone used one of these or any other sunstar brand, I've googled brand and model, just not finding much info, I don't sew much leather, mostly horse blanket repairs, and other items of thicker materials, polyester web strap materials, sometimes bed of my other two industrials is in way to do certain things, cylinder type machine would work in those situations, but I don't know anything about this brand Quote
Uwe Posted December 25, 2017 Report Posted December 25, 2017 My googling brings up good info like manuals with specs: http://lmgtfy.com/?q=sunstar+KM-380 Sunstar is made in Korea. It's actually a good brand based on what I've seen. I have a Sunstar KM-380 but haven't sewn with it yet. It's not a direct copy of any OEM machine I know of, but rather a Sunstar design based on various other machines. Arm, feed dog, and throat plates are compatible with Durkopp Adler 69 class. The feet are very common and cheap Singer 111W style. I've never sewn or repaired a horse blanket, so I can't say if the Sunstar KM-380 any good for that application. Realistically, you'll probably need a Juki TSC-441 class sewing machine (for example: Cowboy 4500, Cobra Class 4, Techsew 5100, etc.) for sewing horse related items. If you're not good with a computer or figuring things out yourself, you may be better off with a sewing machine from a dealer you call for questions (check the banner ads.) Also, don't be afraid of proper punctuation. It's your friend and lets people understand what you're asking or trying to say. Quote Uwe (pronounced "OOH-vuh" ) Links: Videos
Members davehorseblanket Posted December 25, 2017 Author Members Report Posted December 25, 2017 Thanks for the info Uwe, do you know if it uses the bigger bobbins? Quote
Uwe Posted December 25, 2017 Report Posted December 25, 2017 The Sunstar KM-380 uses "normal" bobbins, similar in size to Pfaff 335. On the plus side, the Sunstar KM-380 does have a full motion feed dog, which is somewhat rare among small diameter cylinder arm machines . On most Pfaff 335 and Adler 69 class machines the feed dog only moves back and forth, but not up and down. Quote Uwe (pronounced "OOH-vuh" ) Links: Videos
Members dikman Posted December 26, 2017 Members Report Posted December 26, 2017 From what I've read repairing horse blankets can do nasty things to sewing machines as the blankets are generally filled with all sorts of grit and hair. Quote Machines wot I have - Singer 51W59; Singer 331K4; Seiko STH-8BLD; Pfaff 335; CB4500. Chinese shoe patcher; Singer 201K (old hand crank)

That was my thought too - I would guess a barrel hook machine (CB 2500, CB3200, Singer 45K, Adler 5, Adler 105 and the like) would be easier to clean / maintain around the hook and feed dog.

Would u describe any advantages/disadvantages of a full motion feed dog? Quote
Members R8R Posted October 25, 2018 Members Report Posted October 25, 2018 Many (most) narrow cylinder arm machines can be set up to be dedicated synchronized binder machines. The feed dogs operate horizontally only (back and forth) in unison with the inner presser foot and binder attachment. Most larger cylinder machines operate the same way most flat bed machines do - with elliptical feed dogs. The feed is up/back/down/forward. This is a more aggressive and active feed, but is tricky to make work smoothly with synchronized binding. There are some exceptions, one example is the Juki DSC-246, which can be converted from elliptical feed for general sewing, to horizontal for binding by swapping a few parts when installing the binder features.

Would u describe any advantages/disadvantages of a full motion feed dog? I don't actually do much sewing beyond testing that a machine works as it should. I generally don't make products with sewing machines, I make products for sewing machines. I'm trying to sell most of my machines once I fix them up, except for a select few "keepers". The KM380 is actually a nice machine, but parts are getting nearly impossible to find. I eventually scored an OEM feed dog and an arm cover plate. Throat plates are positively impossible to get - I tried for over half a year. I ended up modifying a throat plate made for the Adler 69 to make it work on the KM380, just so I can make the machine functional. The modification was simple enough, grinding out the underside of the throat plate to make room for the swiveling feed arm to also move up and down. In my mind, the downsides of the slim arm full motion feed dog machines has nothing to do with the function. The full motion feed dog is definitely a plus in my mind, save for certain binding applications as mentioned in earlier posts. The main problem I see is that these slim arm full feed dog motion machines are so rare that nobody bothers to make parts for them (unless they're current OEM production models.)
