How To Choose the right sewing machine?

[MtlBiker]

@Margherita - No photo showing the motor area?  Do you know if it has a clutch or servo motor?  I'd be willing to bet it's a clutch motor.  And if so, you'll definitely want to change to a servo.  Is that some sort of machine dealer, or a sewing workshop?  (Meaning if you can tell if the machine has been used in a high volume production setting.)  

I may be missing something but it looks like the machine has no way to adjust stitch length, which would be something I would absolutely want.

@Margherita - Have you seen this thread from about 3 years ago about that machine?

I didn't sometimes I type on here what I look for and nothing comes up. But anyway I didn't look at motor also because being ignorant I really would have just looked and noticed nothing to be completely honest.
I was pleased with the 6 month warranty and the fact I can notice if something is wrong and bring it back

@MtlBiker but I saw this very useful video and it seems you can adjust your stitch length...

They will install for me also the drop down edge, give me 6 months of warranty, bobbins, needles and shipped it for free.
Since I'll work from home they also said the table could be cut 8' to adjust my space.

It seems in good conditions for 750$ but since I am not an expert I'll ask you

The warranty and delivery at $750 is a decent price. Needles determine what size of thread you are going to use. Typical would be V92 and V138 thread so you would need needle sizes from #20 to #24 depending on thread and thickness being sewn. For Fabric you would need system 135x17 and for leather system 135x16 needles. A good needle reference chart for thread size can be found at https://www.tolindsewmach.com/thread-chart.html

My suggestions:

i) Since this machine has a non standard size table I would ask them to swap that table for a normal size industrial sewing machine table. That table does suggest that the machine was used in production environment.

ii) I would venture to guess this machine has a clutch motor so ask them what the cost of a 550 watt servo motor would be?? The retail price for a servo motor would be somewhere around $200 CAD. If their price is too high then I would strongly suggest buying one and installing it yourself. The learning curve of using a clutch motor can be steep and they are always running whereas a servo motor will give you the control that you need as well as being almost silent when running while you are sewing. I think @MtlBiker may know of un-used 550 watt servo motor.

iii) Get them to go over the machines operating the basics of threading the machine, winding a bobbin, installing the bobbin, oiling etc.

Thank you so much for all the tips I asked the vendor and I am waiting for his reply.

@Margherita - After checking out some reviews of that machine and watching the video you linked to (thanks) I think this might be a really good machine for you.  I don't understand how the stitch length works with a button and no dial or lever, but I guess it does.  Nice things are that it's got triple (unison) feed, a safety clutch and those older Jukis are built like tanks.  I'm pretty sure you'd be able to sell it in a year or two without losing much (if any) money.  Juki machines probably hold their value better than any other brand.

The six month warranty is good, but remember that the machine (even just the head without motor) is really heavy and you'd probably have to take the head off the table and bring it back to the dealer.  But luckily there are lots of repair/maintenance videos around and parts are readily available.  Besides, the experts here are always willing to offer helpful advice.  I do agree with @kgg about trying to get a standard table with the machine even though you're limited in space.  Make sure the machine is in good operating condition and that the dealer shows you how everything works.

I'd say go for it.

One more thing... if the dealer gives you a good price on a servo motor (in case it now has a clutch) and will install it, see if he could possibly install a smaller motor pulley, like maybe 45mm.  You don't need a speed reducer and the smaller pulley really helps with slow speed sewing control.

Thank you again and again! I just called again the dealer and yeah the machine now has a clutch motor but I asked and he offered me a servo motor (plus installation) for 195$, and reading about you and @kegg comments I think it could be a good deal!
My only doubt on it is that I will need to be slow and precise so maybe clutch it would be better for me to start?
Anyway I am pretty set on this machine and tomorrow I'll go there and try it, so I did everything that I could in terms of research before buying it.
The table that the machine have now I think is the standard one, 48x20 or am I wrong? So do you think if I make him cut it a bit smaller it wouldn't be a great move?

When I started accumulating industrial sewing machines, they ALL had clutch motors. There weren't any servo motors available yet. So, I asked the dealers how I could get control over the clutch and they explained the tricks and techniques to me. One thing I did (and still do) is to add slack movement to the control arm so it takes more movement before the disks engage. This is done by backing off the large screw that goes into the motor on the clutch cap end. The more you back it out, the greater the free movement. Next, I learned that applying a very thin coating of machine grease allowed the clutch to slip a bit before it fully engaged. I eventually stopped needing to do that. The final adjustment was positioning the floor pedal to take any stress off of my foot. The linkage coming down from the control arm can be adjusted to raise or lower the inside edge of the pedal to suit your foot and ankle.

The problem I found is that if you are a little tired, have a little leg jerk or otherwise slip a little bit you stand the chance of royally screwing up the piece you are working on. The servo motor provides much better control right out of the box.

The price of $195 for a servo motor installed is a decent price. Definitely worth the investment.

I assumed the table was larger as you said it could be cut 8 feet (8').

Yes the standard is approximately 48" x 20". Unless you are really limited in the space you have I wouldn't bother.
