Just bought a well used (from a major us based auto upholstery manufacturer) juki 1508 as my first machine (although i used this same model at a past job). It functions great, and ive seen no real issues, but its missing a few pieces it seems. The top tension knob assembly, tension bar assembly, balance cover, and bobbin winder tensioner are all completely gone from this machine. Ive ordered all the replacement parts (except the balance cover, as they seem to be out of stock everywhere!), and the machine seems to sew perfectly as is, so i guess my question is as much acedemic as anything- why would these pieces ne removed, or were they perhaps optional or revision add ons, etc? The mounting holes for all of it is there, just not the parts. What possible benefit could there be to not having these tension items? My first thought was perhaps this machine was robbed to fix a better (cosmetic) condition machine, but all 29 machines i had to choose from were missing these same parts. It is an older machine, made in japan, model lu-1508n. Also, its a bit late to ask, as ive already purchased, but i ended up paying 900 for the machine with a servo motor. Is that a fair price? I bought it mainly as i have really only used jukis, and i didnt really want to learn much about the consew 206 machine operation (call me closed minded, my old jobs old machines were absolute workhorses, so i knew they were a quality machine!)
Again, ive ordered all parts i could, and machine runs great, so im mainly after general knowledge here.
Thank you all so very much, and i really look forward to learning, and contributing as i can (i focus on auto upholstery for my own cars, but love leatherwork in all aspects, most of you guys are absolute craftsmen, and im thrilled to be here!)
