I’ve never used a sewing machine before and just stitch bags and wallets by hand. I am considering a second hand Juki LS-341N as my first machine, and I have a few questions. I’m really hoping you could help me out.
Is Juki LS-341n a good machine for stitching 2 to 3 layers of 2mm vegtanned leather?
How about oil or chrome tanned leather? Denim? Thick canvas?
Do I really need a servo machine with it? I was told by a local dealer that it is more expensive than a clutch motor and since electricity in our country is not that stable, any fluctuations will damage the computer board of the servo motor. Will using an AVR solve the problem? Also, what specific things should I look for in a servo motor?
I also remember the dealer saying that locally available servo motors are too weak. We use 220v here. Can I use a 110v servo motor from the US and just have it shipped here? Is that a good idea? If yes, what specifications for the transformer should I use?
If I won’t be able to get my hands on a servo motor immediately and have to use a clutch motor, what should be the specs? What should I ask the dealer/mechanic to do with the clutch motor so I could use the sewing machine while waiting for a servo replacement?
If I use the machine with denim, or denim and leather, do I need to switch to a clutch motor?
For 2 layers of 2 mm thick vegetable tanned leather, what kind of needles should I buy?
How about for 3 layers?
I plan to use Vinymo thread. What’s the thickest size I could use with the Juki 341n and what kind/number of needle is appropriate? If I go a size thinner, what’s the corresponding size of needle should I use?
I’ve read that some sewing machines tend to leave marks on the leather. What is that part called? Is there a special tool I could use to avoid that? I’ve also read that some people had to file down the ridges. Could I buy an already-smooth one?
What other things/attachments should I buy so I could maximize the use of the machine?
Sorry for bombarding you with questions. Although I’ve read some posts pertaining to this specific machine, I wasn’t really able to find out if it’s okay to use it with vegtanned leather. Thank you so much!
