Consew 310?

[blafleur]

Anyone know anything about the Consew 310?  Found one locally that looks to be in good shape and was very cheap, so took a chance and got it, figuring that being an industrial machine, it has a good chance of doing leather.  But I can't find anything about it, no owners manual available, even from Consew. 

I don't know how to sew yet, but if this one would work for 8-10 oz leather, I'd like to start stitching my belts and straps with it.

Thanks,

Bryan

Could it be 210?

[blafleur]

Definitely a 310.  But I did find an owner's manual for the 210. I wonder how close they are.

[CowboyBob]

Yes,I found a 310 parts manual  & it looks very similar to your model.

The Consew 310 looks to be a bottom+needle feed design, based on the Consew 310 parts diagram.  Not a bad starting point for leather work. 

Finding parts and service information for this oddball machine may be hard. The fact that the parts book doesn't even tell you what needle system to use is not encouraging. Hopefully the machine came with a pack of needles or a sticker that indicates the needle system.

Since you already have the machine, the best way to find out if it will sew 8-10 oz leather is to just try it out. Get some leather point needles of whatever mystery needle system this machine uses and experiment.

It did not come with needles. Is there a way to tell by looking at the needle holder?  On the Consew parts list, it lists needle as part number 2110102-194 but I can't find any reference to that.  Mystery machine is right.

I guess a good place to start is with the 210 needle size (Needle style 16 x 257)? Put one in, turn by hand and see what the timing looks like.

I believe that needle number is 2110402-194 in your parts book 

Over on thread exchange their showing some Groz Beckert needles for the 310 as these: DBX1- and or 1738A. 

Showing a few different for thread sizes. 

 

Good day

Most needlefeeds take a larger shank then the 16x257,the same length is 135x5 or for leather 135x8.

This may be an uphill and loosing battle. Remote crowd sourced support, being new to sewing, dealing with a mystery machine that has experts guessing at the most basic information is not an ideal combination. I predict lots of frustration all around.

Post some detailed photos (good luck figuring that out on this forum) of the machine including any markings or brand stamps you can find on it or on parts inside or under the machine. Your only real hope may be to find out who actually manufactured the machine and what the original model is. Consew doesn't manufacture machines, they only put their label on machines made by others (Seiko etc.) - and obfuscate documentation to render it nearly useless. If you can find out the original make and model, you have a chance. Otherwise, you may be better off starting with a different machine.
