will juki 1341 accessories fit this Typical tw3-343?

[TakashiOkada]

Hello. my machine just arrived! I promised I'd post some pics so here they are. thank you so much for your advice! it ended up costing 2,016 US$

Sadly the smaller table you guys recommended to me has to be imported and it's gonna be prohibitively expensive so I'll pass on that one. 

This is a typical TW3-343. I was planning on buying a typical 341 which is a direct clone of the Juki 341 but the seller told me there's a new version, that's why I went with this. It resembles a Juki 1341 but the bobbin winder is in a different place and it has full self lubrication, not only at the bottom like the 1341 AFAIK. it came with a 550w brushless servo motor. if you guys know which clone this machine is from I'd love to know. I have also want to know if this flat bed attachment will fit.

the bobbins are HUGE, bigger than bobbins on my Seiko tf-5/6 and post bed. It also came with a binding attachment which I appreciate.

I don't know if this is normal but the pedal that lifts the presser foot is not smooth at all and I have to press significantly harder than the motor pedal, it's uncomfortable to use with an office chair with casters, is this normal? I'm asking because I've never used anything other than a knee lift so I don't know if this is something I have to get used to or if it's something that needs to be addressed.

I have a small speed reducer I bought from aliexpress couple years ago that I could Install but I'm hesitating since I've read some threads saying it doesn't work well with needle positioners.

This is a question that you should ask the manufacturer, if you can find their website, and if they have a contact form. If you can't find the manufacturer, contact the company that sold you the machine. Maybe they know how to reach the builder. 

You attempted to link to a flat bed attachment, but neglected to include the URL. Please try again.

Looks very sturdy.

What is the diameter of the bobbins?

Your chain is rubbing on the table. If willing, you can drill a hole closer to the machine that will be a straighter shot to the pedal. Also, if the chain still rubs, replace it with a cable, and make a slide for the cable out of some vinyl and grease the vinyl.

Also at the foot pedal end, the chain is installed in the default (but unfortunate) position of out at the tip of the pedal. You probably don't need that much lift. Mine I drilled a new hole a couple inches down from the tip and it gives me enough travel will less force.

 

Another help is to reduce your presser foot pressure. For very low pressure, I remove the presser foot spring, but on very thin fabrics I need to keep the spring installed.

Oops you're right. This is the link.

It's for juki 341/1341 and clones but this is not exactly a Clone so I'll have to ask the manufacturer. Thanks  

Thank you @friquant . Apparently the problem is not the chain rubbing, I held onto the chain to prevent it from rubbing and there was no difference. Something in the mechanism feels clunky, I'm going to try the pedal and presser foot tension suggestions.
Diameter of the bobbin is 25mm.

You can stand behind the machine and press down on the lever with your hand to check how smooth it moves without the pedal being in the way.

You may need to grease the part that slides up and down near the presser foot.

Cool! The bobbins on my jianglong 341  are 20mm.

I use an office chair with caster on all my machine without any difficulty. I have seen the foot lift to be more difficult then the using the rear presser foot lift lever for two reasons. 1) a missing washer on the pivot point of the the foot lift lever at the rear of machine and 2) the point of contact of the foot lift lever at the head needed to be adjusted / oiled where it made contact to lift the presser foot. You should check and see if the knee lift shaft is binding which maybe contributing to the hard lift when using the pedal to lift the pressure foot.

Also:

1) The location of the cable to the foot pedal should be mounted to a bracket that is mounted to those two rear holes in the pedal. The closer you move that cable to the pivot point of the pedal the more difficult it is to operate.

2) Since you like using using a knee lift there should have been one come with the machine and it bolts to the shaft extending out of the base of the machine.

3) You should check and see if the knee lift shaft is binding which maybe contributing to the hard lift when using the pedal to lift the pressure foot.
