Look on the leftside of their homepage(it says manuals),for some reason I couldn't cut & paste the page into my post.

try Proleptic they have them.

The easiest way to change it is,take both feet off,then take needles plate off,the take the bobbincase opener off,then you can loosen the 2 screws on the small gear on the hook pull it out being careful to not let the gear fall off,also notice were the slot is in the gear so you can line the now up the same.Re-install everything & then check to make sure the new hook point doesn't hit the needle & that's it.

Nakajima was bought out by Juki many years ago.They redsigned the machines & parts put new model # on them & some parts are no longer available for this model.

Catskin, Yes,you have the same motor.We have always felt they worked pretty good esp when connected to a speed reducer,but I guess it's like anything you buy some people need it to be different.Look what they do to a new car or truck,jack it up big tires,loud exhausts.paint,sunroofs & etc. It has been some very interesting reading & way over my head since I'm not into electronics to understand it all. This motor is 1000x better than the one we used to sell that you had to program for the speed,it went from 0-wide open in 1/2" of foot pedal push.

To be honest with you I don't fully understand what you are referring to.Do to the way this machine is built it is pretty hard to put it together wrong.. Some pics or parts # would help me understand better.

Hello Manny,did you get your machine going?

They are a great machine as long as you want to sew under 1/2".Don't forget to take some samples along & try it out.

The 345 will sew much thicker than the 335 so you should try to sew on the 345 before you buy if possible to make sure it works for your thickness.

Yes,the 111w153 is almost the same machine,put a D.C.Servo motor on it for slower sewing.Parts are also readily available for it too.

This is a good machine for sewing canvas or vinyls BUT I would never recommend it for sew leather esp fine or thin leather.Reason being is this machine has feed dogs & feet with teeth on them,you can grind off the teeth on the feet & stop the marking on top but you need the teeth of the feed dogs to pull the leather through which can leave marks & can scratche when turning.You would be better suited to look at Juki's 1541S model or similar machine like Consew 206RB-5 which have a walking foot & needle feed,the 206 has an optional slotted needle plate for it the eliminates the feed dog so you won't have any marking on your leather.Highlead 618 is another good one to look at.

Yes,a standard bobbin winder will work.We always use the 135x16 needles in these as the 16x99 &100 aren't made anymore.

Do you have a machine now?If so what is the model#?

You have some good susgestions here already but,I'd like to add one more,watch the thread as your sewing between the thread stand & machine to see if it ever looks like it tightens ,once in a while a spool is defective & as it comes off the spool esp on the bottom it gets pinched & causes this problem.

So what he needs to do is spray some penetrating fluid around the button,go underneath & push it up & then push it down from above to get the fluid worked into it.

I have one in my collection that I got to make some stitches.I'll have to get my camera over here & take a pic of the threading for you.

It isn't the best for leather & the price is alittle high.It has an outside foot that has teeth on it that grips the leather as the feed dogs pull back.These teeth will leave marks.A walking foot needle feed machine will work better for you.

Yes,the needles now have the scarf in them.

That adjustment is for the front to back of the hole.Is your feed dog loose?

There is nothing in that part of the machine that would adjust the needle to the right,only front to back.Is there any left to right play in the needle bar?Sometimes this model can get play (left to right) in the feed dog,the track the feed dog slides in may need adjusted.

I got a good buy on some 29x3,that's all that's on the box they are Groz-Beckart,but they are really 135x17 they have the scarf on them.It is my opinion that with this scarf that the 135x17,16 has is that you can move the needle closer to the shuttle for less chance of shipping stitches. To my knowledge there is no more 29x3,4 left.We have been selling them 135x16,17 for years instead & they work.

Here's some directions,you only have 5 seconds to complete your task or you have to start back @ the beginning.

The stitch length is the square thing just above the foot,the lower you adj it the longer the stitches.The knurled screw is the foot pressure adj.,the wingnut lifts the foot so it clears the leather as it goes foward.You can usually push the wingnut part as far towards the center of the spring as it will go & leave it.You might need to get a new foot as the teeth get dull after while.

The best thing to do is take some samples of what you want to sew & try it out to make sure it'll handle it ok.

This model 28 is the same as a Singer 78-1 or-3 machine.It should sew the same as a 31-15 up to 5/16" around 20 oz of leather,it would be good for wallets,chaps & etc.
