I just thought I'd throw in my $0.02.If your not careful when threading this type of tension unit this can happen because the thread isn't pulled past the little guide on the lower thread disc,called thread controller.Sometimes the little screw loosen & it'll turn clockwise & put this at an angle that will make it hard the get the thread in past the guide, so the little screw should be in the middle of the slot,if it's on the leftside then here is where the problem is,See attached diagram. When you thread this you pull it down the rightside,under,up the left & pull the thread to the right until you hear a snapping noise,then it will be behind were it belongs & won't jump out when your sewing. HTH Bob

Andrew, We have them,give me a call. Bob

The problem with the Boss is the needle is so long & of course when you go maller it'll bend & break alot easier.The smallest size made is a #110 which is what I recommend for #69 in these machines.A 120 would make a larger hole. Bob

Trox,how does the bobbin fit on it? :rofl:

The Consew or Juki would be the best bet.

Ok,once you set the timing so the needle rises 3/32" from bottom dead center,then you need to make sure the needle height is set so the point of the hook is about 1/8" above the eye of the needle & it should sew.

Does it sew?

Hello, Are you sure your sure your using the correct needle? it should be 21/8" long. Bob

The tension discs in the front are used for darning. Bob

Tom, To time the hook,the hook point needs to be @ the needle when the needlebar raises up 3/32" from BDC . Let me lnow if you have anymore questions. Bob

Less foot pressure will make less feed dog marking.If your feed dogs have teeth on them you can polish off the sharpness will reduce the marking too. Can you post a better pic were I can see the top lefthand corner of the machine,it's cropped off on this one. No,a roller foot cannot be put on a walking foot machine. Bob

Ok,I'll sure let you know if I hear of any. Bob

Hello Eric, That's when I got into this business is 1980.I don't have either model in stock @ this time. Bob

Your turning the wrong screw,the correct one is located behind were the spool of thread is in the pic,it takes a screw to go the the hole to loosen it. Bob

Ferdco took the standard Juki feed dog & needle plate off & put a slotted plate & the lower needle guide on these,the problem we found is the stitch length shortened in reverse w/o the feed dog being there.

Now that I'm fully awake,I'll explain it better.When it makes that noise it can lift the foot (with the leather) up on the upstroke of the needle & when that happens it won't make a good loop for the shuttle to catch & that will cause the skipping & frayed threads just like the timing being off will. Bob

Mark, Sounds to me like your sewing on old or dried out leather,that's what the noise is,try putting some lube on the leather or at least between the 2- pieces & I'll bet the noise will go away. Bob

Mike is real close,although it's more like a Juki 563 or Consew 255 w/a vertical bobbin, around 1/2" foot lift should sew 20 oz of leather,use up to #138 thread & it takes very common pressure feet just like the Juki & Consews. HTH Bob

I'd rather own a Mitsubishi than a Yamata there's a big difference in quality.

If it includes the table & motor yes that's a great price.

If I was some 2000 miles closer I'd buy that Juki myself,your right tnawrot2 that is a great buy!I've seen alot worse looking ones than that. Bob

Yes,that is a walking foot machine that would work for upholstery. Bob

That's probably your best choice.

Yes,parts are alittle more than the other machines,so are the feet,all the above machines I mentioned take the same feet so they are inexpensive

Yes,if that's what you want to do is topstitch seats even 138 is plenty large enough.The Nakajima 280 isn't the best machine for large thread.Get a Singer 111w,211,Consew 225,226,255,206,Juki 562,563. There really isn't much difference between the above models except bobbin size & where it loads.
