I think while holding the thread at the needle when, take-up lever is at top you can pull a good amount of slack to hold stoutly for starting off the stitch seam. Keeping a good amount of that thread in hand on this machine when starting should help. Most times i try to have this slack and also to have the needle buried in the material works really well. Hope that can help, i am finding in listening around here that no matter, they all have their own likes these machines. Good day Floyd

I thought the 1541 juki was based from the earlier 241 type. And my 1541 uses the 111 singer styles. Though many can be purchased i only found factory to be consistently accurate in mounting dimensions. Floyd

Heres a post with some great tips on that one, interesting there is two shank sizes they discuss a bit. Floyd http://leatherworker.net/forum/topic/59564-needle-dimensions/

Probably need some pics, if not using a link to your photo storage site like photo bucket or other kinds some use. Then ive heard resizing a close up picture to about 128kb size. This can be seen when your mouse is on the newly sized photo. Anyway if where the needle area is, and there is 3 seperate post coming down. your on a roll with a walking foot machine most likely. Something interesting is if its a flat bed style or if it has the cylinder arm style off the side and some have the post style sticking up. I seen in a search cylinder arm but without a bit more, my or others search or familar knowledge is up in the air. And we dont want to bother ya with a bunch of links. Glad to help! Fwiw sometimes here in the last 15 years many copies of other machines have been cast. Some have great new mods so it can be tough. As several tags can be installed, some brands with different attention paid to modifications be it dealer design or just dealer adjustments. Floyd

I would consider a bit more towards the machine with a pulley wheel. Good luck Floyd

Its so much easier re-looking up post on a pc versus a d phone. The scrolling for me first gets a rating, and well. Anyway probably best to ask how much or whats hook to needle clearence look like. But it is running about center on feed dog so kinda puts the cover at first ? My standard cover is not slotted at the screw hole on my Cobra. Although in looking at other photos some i seen some use this. So if there is room at edge of cover say next to the casting, slotted holes could be handy. Floyd

The bonded would have a coating applied somehow. And as you mention your doing, running bonded topside. This is the design intention to better help in higher tension or stress areas and these type mechanical situations. I believe speed of stitching also plays a big roll here as this can develop heat. A supportive and may well be a sales point. Is some bonding specific applications this is to also add better results to usage of products. Good day Floyd

Im not sure on which descript in a mobile table im only recalling the typical 4500 stands. On some other ones with top that has a center open design i can see them being easily mobile. Myself struggle with to many seats and heights so try to keep my ocd pattern the same with machine setup. Floyd

I found 3 different factory installed parts. The one in the photo, one with slight drop in the eyelet hole about a 1/16" or better. Another without eyelet just a small tang wraped around so making it easier to insert thread behind it. None of these parts make much difference in this issue. About .015" at the top of the walk foot so .415" bottom side. So one can assume with perfect alignment the outer presser foot will be ok. Though in sewing super thick stuff the part with the drop down would get trashed by the walk foot first. Versus the others hitting the outer presser foot top as i see it. The best option i found for myself is to use the 190 system needles in these 15 series if your sewing over .400". The 190 sys will fit the same wheather a 1341, 1541,1541s,1508n, 1508nh and quite sure the other super pro 15 series. I found this problem in a (few) begining noise moments and said self this banging crap has got to go! So in digging around found the 190 sys will give ya like 3/16 of an inch more. Floyd To offer another great reference: http://leatherworker.net/forum/topic/42556-anyone-have-experience-with-juki-1508-nh/

I recall reading on the site here somwhere, the machine likes to have about an eighth of an inch more clearence than the material. This was a good tip i do believe. On a measurement here i get .400" with feed dog to bottom of foot clearence. With one cup of coffee this morning! It could get more scientific later if needed. The part mentioned in post is touching the top of a factory walk foot in my measurement. This part surely can be had cheaper and in an Original part, totally agree. This measurement i mentioned is with 135X17 needle sys setup. This setup i havent made time to change anything. I think there are options available though, needle bending has been a concern spoken about. Honestly with this thickness of material it may be time to consider other machines. Soft rope cording or the likes i wouldnt have an issue considering options. But with that .400" in a solid well? So if on the lighter choice i can offer a bit more, as others. good day Floyd

The motor looks in good condition from the photo. I agree the wiring can age out and i my opinion think much of this is just the makeup of the wire coating not so much heat cycles though a concern on all circuts. So i would seriously consider what type wires are in the flexible metal conduit. If its can help maybe. I use a hot knife many times at machines. With that and a concrete floor i have installed one of the metal "handy" electrical box on my machine k stands securely. The idea is to benefit using a gfci recepticle and i use the deep double size box as the main input junction. I only mention this as the system there in the photo should have a seperate ground wire added just because that was the next newest update in them days. Im just getting to old for the jolt these day i only want that from the coffee. Good day there Floyd

Welcome to the machine area Yes on two machines, your holster you mentioned needs big thread so a Juki 441 or the famous clones made from that. Seems everybody needs the mid size machine to work a majority of the other load also. You can find excellent new hardly used machines, if i can so can you. The key is patience so in the mean time look for the singer clones, but classed/ called compound walking foot style. This is just the ticket ya need. Listen up to these others on here i have learned a great deal from this place myself. The secret with all purchases cash in hand and willing to travel. Floyd

There maybe somewhere an illustration on the adjustment here but its not in the Juki engineers manual where i have noticed. So any of you are more than welcome to share the typical adjustment and or measurements. I certainly would appreciate the information. Thanks Floyd

Thats what gets my goat, i got all worked up on mine and so got ready. Did work outs! Push ups everything. Even brang all the tools in, a new pot of coffee. I made the call and like : do this, i did and it was fixed and done. Dam coffee in my cup was still steaming. Floyd

Its dry. It may be possible to remove the top presser spring retainer nut totally. In doing this a better oiling of these parts surely could be tried. This seems to be a new machine fit type issue though a pain i think a bit of time and youll be off n stitching. I had earlier tried myself manually lifting the presser foot on mine at its mount point and this is handy. Have a good weekend Floyd edit: oh the ole chatter roller ya!

If when you sit next to it and manualy lift up on the foot at the mounting is there noticeable drag. You could remove the side for a better oil app possibly. I had a great talk with the tech at leather machine so do give them a shout back in the shop good day Floyd

Interesting tip, thanks my cobra has a flat ledge at bottom sticking out maybe? an 1/8" with a small thread hole. Versus the ring band as your photo which looks to have plenty room. Looks like a great mod. Good day Floyd

Hey Zach i found the top of the belt rides on the pulley outside, so easy method is wrap some painters tape around pulleys tape together, mark and then cut. Measureing this is i think spot on, in your hardware stores the appliance v-belts are typically a "B" series and what you need they come in 1 inch measurements. That treadle is a nice one with good end bearing mounts! Any way it looks to be missing a small bracket mounted accross the toe side, left to right. You may need to find or make a 12"flat steel piece replacement with the end having a say a one or two inch long 90 degree turn with a hole drilled to accomadate your purchased linkage. These many times are adjustable on them screws as different motors and the likes. Good day Floyd

Dont forget the newest Cobra 226 machine in your line up. On a side note the photo machine is sure positioned as mentioned to be gone! myself i would look at your list it seems the right path. If you wanted some more discussion on a local option further in your search page is a 335 clone that may or may not be your top choice, i mentioned mine but to be helpfull here in your original post is worth talking here. https://sfbay.craigslist.org/scz/art/6049276746.html good day Floyd

Ya thanks Wiz i did finally go look, not my standard! Okinawa, Japan it is many times i enjoy the curious aspect of questions posted here on the site. No offense here but it seems advertisingly sometimes Floyd

Just a lighter duty walker style and in their materials work fine. Ive seen 1181's used in light canvas as a starter and work ok. I know juki made many for factory setting, so like us they did the cost thing and for them operations worked. We can get a better walker/compound and lighten up the presser n tension if need be. Like for many different upholstery textiles that like/demand a lighter foot presser. Good day Floyd

Likely a savings "somehow" with the servo mounted there and its control screen on the surface. I would think a machine operations not needing the extra typical torque for leather work as one gets from a reducer installed pulley system. I honestly cannot see any usage of oil lubrication on the machine head. Only the air over mechanical system for operations. I would just order a machine from one of the dealers frequenting the site here, when a budget is set. Where is your location ? good day

For no insurance that is quite the rate. I dont think mine were that much with! 2.5k worth of ins and shipping clear across the country. Maybe some of that was preparation cost, in that case thats something to consider. Because in my mind 500 bucks should have included a 1/2 pig iron casing all filled with expanded foam There is no easy answer after these kinds of incidents thats for sure. i hope you can get something worked out Floyd

The many you see on here used dont have the swivel type presser foot. Them as the photo typicaly are in the other single feed type machines and some dual feed machines. It is an industrial though, looks to me for lighter materials than what your projects are seriously into. Good day Floyd

I have heard of the need before to get more height from the hand raise lever. So with some interest i am curious also. good day Floyd
