If it was looping on top of the material then it would be the bobbin,looping underneath is always the top thread either too loose of tension or threaded incorrectly(on the top) or to large of thread for the machine.

Ok,I guess I'll have to add my 2-cents,Art makes a very good point these machines are much better than years ago.We do not see abnormal parts breakage or flaws in these machinea.If we did we wouldn't be selling them. The best part with either the 205 or 441 type of machine made in China is if needed you can buy the parts from either Juki or Adler since they interchange.So you'll never have to worry abnout parts not being available.

Hello,have you tired searching the site as most questions you have about leather working have probably already been asked & answered here & are in the archives. Welcome to the site. Bob

Great job there, Welcome to the site. Bob

Nice looking work you have there. Welcome to the site. Bob

Great Job there, very professional. Welcome to the site!! Bob

WELCOME ABOARD, nice looking website as are the conchos. Bob

Hello Bill, You sure found the right place if you want to sew leather. Welcome aboard & if you ever have any questions about your machine feel free to give me a call. Bob

The max would be 3/8",but the stitch will look bad on the bottom side no matter what you do since the bobbin loads from the front instead of the side.The needle threads from front to back instead of left to right. If you want to PM me your email I'll send you some pics of the shuttle & you can see the way it loads from the front. Bob

Knut is right I know thw 105-25 is for sewing moccasins,so the 104-25 is the same machine only a flatbed,the top foot can be adjusted to make shorter stitches than the bottom so you have the ruffled look.The bad thing is on their shoe type of machine like this model the hook runs the different that the standard machine & makes a weird looking stitch on the bottom side.Just sew on some leather before you buy it & you'll see what I mean. Bob

The 29's top foot is what pulls the material & it has teeth on it & it'll leave alot of teeth marks on the topside of your leather. That is why it's called a shoe patcher,for making patches were people don't care what it looks like.

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

The looping underneath is always the needle thread either it's to loose of a tension setting(on the top tension) or threaded incorrectly.

Here's a threading diagram. Bob

Hello, If you need smooth feet you'll have to grind the teeth off(I've done this quite a few times for these machines) as you can't buy em. Bob

another thing I've found helpful since picking up my machine is leaving a healthy 1/2" allowance on things so that there's room for the presser foot to be on the outside edge of the piece, allowing me to get right tight to where I want to be with the needle. That's a great idea.

Be sure to wear a flame retardent suit when trying this!! No,the larger thread could jam it up. Bob

The 135x16 & 17 will still work in this machine. To get to that screw,there's a square hole on the end the the arm,you need to take a flaslight & look in there as you turn the machine slowly you'll see it & go in the hole w/a small screwdriver to check if it's tight. Bob

Your Welcome,let me know how it works out for you. Bob

Hello, Here's a threading chart & we just recieved a large shipment of thread & have the needles in stock too. Bob

I usually recommend the largest you can use without giving problems is #138,IF your careful & you hold the threads carefully when you start sewing & tighten up the needle thread tension alittle more 207 might work. Oh,you need #22 needle for 138 thread & #23 for 207 thread. Bob

A Pfaff 563 is a light duty tailor machine. Bottom feed only. Bob

Yes,there is many different lengths of needles that come in a #22,but you probably got 135x17 which SOME 1245's take but it sounds like you need the 190R for your machine. Bob

Doug, This screw is a 9/64 40 tpi Bob

Usually the race wears,it's cast iron.The hook is chrome steel & doesn't hardly wear,the tip can get damaged though. Bob
