I will check this tomorrow morning. I was told the mechanic at the company where I bought this should be back from vacation tomorrow as well, so I will give them a call and see if we can figure something out. Machine is maybe 4-5 months old so it is still under the warranty.

There doesn't seem to be a position for the pressure adjuster screw where it doesn't jam up, and it still jams without the screw. When taking apart the machine again today, trying the method Tequila mentioned above, I didn't see any burrs. I also slid the piece that moves through that slot up and down and met no resistance. But I noticed the walking foot was meeting some resistance when sliding it up and down by hand so I removed the "upper feed bar guide" from the "frame driving base", oiled it and put it back together (names are according to my parts manual) This reduced the resistance but when I put it all back together and timed and recalibrated, the problem still persists.

I think you are referring to the area circled in blue, it actually doesn't seem that the wheel contacts it at all during its travel, but I loosened it some more. When I take it apart again I am going to check on this slot circled in red because I don't believe this machine came adjusted to with the presser foot travelling very high, and this issue only seemed to appear when I tried balancing the feet. So there may be something going on there and I never noticed it until I attempted to balance them. I loosened it and it still happens, I took it out completely and noticed that when it starts to jam, the top of the presser bar that sticks out tilts towards that balance wheel side of the machine. At this point I am open to try anything to get this thing working, I'll check this tomorrow or Monday.

Still no sadly, I took out the linkage entirely, checked for defects found none. (I've basically disassembled/reassembled the entire presser bar / walking foot assembly at this point, I'll check again, but I don't have very advanced measuring instruments, just a granite slab and digital calipers) I got the presser foot to start lifting as the walking foot goes down again, but then it still jams once its maybe 1-2mm up , if I lightly tap the linkage with a rubber mallet it will begin the move again in spurts. If I adjust it so the presser foot does not lift at all, then it does not jam, but then obviously it doesn't feed correctly. The L shaped piece is very slightly bent or maybe unevenly flattened. I put it flat on a granite slab and pressed lightly on it and it wobbles the littlest big. Visually I can barely even see the unevenness, so I don't think its the cause. But I've been wrong before.

So after fussing with it some more today I have a few notes: - I believe the other day I actually ended up adjusting the cam all the way around to where it originally was, so it was probably in the correct position and that the walking foot is still supposed to continue to move down and this causes the presser foot to rise. - I took the presser bar out of the machine and rolled it on a granite slab to check if it was bent and then pushed it through the presser screw back and forth and met no resistance. I believe that neither of these parts are defective. - It seems instead of lifting the presser foot after the walking foot goes down, instead all this linkage circled below seizes up. I gave it a generous oiling after taking putting the presser bar back in, which helped notably, but I do not think this is a lubrication issue. And when I lift the presser bar on the foot pedal, it unjams.

I have done this and got the lowest point on the walking foot to match up with when the needle reaches the needle plate level, however now I am getting a slightly bind whenever the needle is almost to its highest and lowest positions. (the whole machine creaks while I push it through, but doesn't stop stop completely. The needle bar and take up lever seem to vibrate the most as I push it through.) Additionally I cannot get the presser foot to lift when the walking foot is down.

Machine: Ferdco Superbull 2500 (Juki 441 Clone, like the Cowboy 4500 and Cobra Class 4) I bought the machine about 2-3 months ago new from Hoffman Bros., it hasn't really had any issues other than a slipping bobbin winder. I had a binding issue a couple weeks ago and after some research I thought it was an eccentrically drilled presser foot pressure screw (I think if this is the case, it caused this issue but I am not sure) Soon after the bind stopped (I don't remember if or how I fixed it) A couple days ago I noticed my walking foot was traveling WAY higher than the presser foot and I was having issue traveling up layers of material. So I watched Uwe's video and this video: After watching these, I attempted to fix the issue, but it revealed that the problem was much worse. The walking foot wants to continue to move down after the needle is already on its way back up. However the presser foot still starts to move up as it should, until it binds. I believe this is causing the whole machine to bind up as the presser foot continues to push down after hitting the feed dog The needle to hook relationship is still correct The walking foot moves backward with the feed dog as it should The needle still travels backwards with the feed dog as well I cannot figure out how to make it so the lowest point of the walking foots travel is when the needle reaches the needle plate. Photos: The machine when the needle is at its lowest position The machine when the needle is at its lowest position (presser foot lever raised) The machine when the walking foot is at its lowest position (presser foot lever is raised otherwise it would bind if I tried getting the walking foot to it's lowest position) I believe the culprit is one of these two, but I don't want to move anything else around until I know for sure what the cause is.

About two weeks ago I was talking with Hoffman over the phone, they told me they bought Ferdco about 5 years ago (If I remember correctly) but they haven't advertised it much. I ordered a new one, but wanted to make sure anybody buying used offers a fair price so they wouldn't feel jipped if they later learned the cost of a new one. Comparably a brand new CB4500 (the same machine with a feed dog and all the accessories) is $3400 + Freight Beautiful work by the way.

You can get a brand new one from Hoffman Brothers for around what you're asking.

About this machine: Compatible with most Kingsley accessories This particular model was designed with luggage in mind, so it has a 9 1/2" deep throat. It is also mounted on rails so it can slide out if you need to reach deeper into something. The machine itself weighs around 30 lbs Everything works; ram, thermometer, heating element. (uses flat mica strip type heater) The dial might have a few dead spots like most of these older machines, I just plug it into a wattmeter so I can see if it's not making contact and move it a little bit. Maybe you could open it up and clean it? I haven't tried. It looks like a carbon contact that slides on a resistive perimeter to vary the resistance. Not sure what the technical term is Note: the handle was replaced with a screw driver, it works just as well (if not better, it's much quieter). Locking pin in the back (which allows it to slide forward off the base) was replaced, so it jiggles a little bit. Includes: - The machine it self - 4 types of foil (Matte Gold, Shiny Gold, Silver and Brown) - Single Line Type Adapter (you will need to get a type holder as well) - Kingsley Magazine / Brochure - Vintage Kingsley "Small Parts" Box (broken hinge) Before you can use it you'll need a type kit, type holders and I would recommend a ruler guide. $250, Local pickup in Middle Island, NY or Shipping estimates after the cost of making a wooden box for it: - To LA, California: $100 - To Dallas, Texas: $90 - To Portland, Maine: $60 - To Alaska or Hawaii: Don't even think about it I'd ship it FedEx Ground or Home Delivery Photos:

Yes I will. PM me so we can exchange contact info. That is quite a drive from VA.
