  1. The last time I owned one of those Singer 127 / 128 models was about 10 years ago I got it for $50 from an estate sale in working condition just required the wood work to be refinished. I think people buy them today mostly for a show piece. What I have seen in the used market over the last couple of years here in Ontario is: i) The featherweight Singer 221's asking between $300 - $900 with the white ones closer to $1500. The free arm version always seem to sell for $200 - $300 more. I had a Singer 221 for a short time, nasty little machine, they seem to be popular with the quilter groups as they are light to carry (about 11 pounds) from place to place. ii) I think if someone needs a drop feed domestic the Singer 99K's are pretty bullet proof and can be had for about $200 in excellent condition. iii) Singer 29k's asking range between $400 to $1000 depending condition and on whether they are complete with the original base, flatbed attachment, manual and threading rod. This is up from a couple of years ago from the $200 to $300 range. Why???? I just pickup a 29k-71 with original base and in decent working condition all it needs so far is a little TLC. If it doesn't do what I am hoping it to do I'll sell it in a couple of months. iv) Juki 563 asking range between $900 - $1500 up from $500 - $700 a couple years ago. v) Since Covid 19 the prices have been increasing to point that it is just as well to buy new for what people are asking for used industrial walking foot machines. Just my opinion. kgg
  2. I would say that all the brand name threads are probably within a certain tolerance of one another. The cheaper quality no name brands who knows. The strength would probably be in the far north of a 1000 pounds. kgg
  3. A little more harsh then myself but when I need a good quality item I look at items made in North America first, then Europe, then Japan, then South America with China being a last resort. I have bought fabric out of Paraguay, desktop fabric strip machine for making binding out of Brazil, 3d printers made in Czech Republic and sewing machines made in Japan. kgg
  4. From the information I have see I think it would be be based on the number of stitches per inch. The formula would be the number of stitches per inch X the breaking strength of the thread X the thread loop factor: Example would be: stitches per inch: 5 V69 breaking strength equal: 11 lb thread loop factor for 301 stitch (lockstitch) type: 1.5 and thread loop factor for 401 (chainstitch) type: 1.7 Lockstitch Seam strength = 5 X 11 x 1.5 = 82.5 lbs. Chainstitch Seam strength = 5 X 11 x 1.7 = 93.5 lbs. The reason a chainstitch seam has more strength for the same thread size with the same seam length but there will be about twice the amount of thread used. kgg
  5. I would suggest using 138 in the bobbin. If you use a smaller thread in the bobbin the strength of the seam will be limited to the lesser thread size in the bobbin. If you use a larger thread in the bobbin say 207 the seam strength will be limited to the capacity of the 138 thread on the top. kgg
  6. I believe in buying good quality tools / equipment not necessarily the best or even new equipment but not the low priced cheap quality stuff unless I am going to treat it like a BIC lighter. If you don't like a particular aspect of the hobby chances are you can resell good quality equipment otherwise you maybe stuck keeping or taking a bath on resale. There is always a market for good used quality equipment. Good quality equipment always lessens the frustration associated with learning something new and helps, at least me, to concentrate on learning. I have always liked good quality equipment that was above my ability level, one less thing to wonder about. Equipment or me, most likely me. I typically try to follow the Buy Once, Cry Once method of buying equipment. It really depends on what someone wants to do and how much money you can afford. Example you can make a leather wallet using thousands of dollars in equipment like clicker presses, electric skiver, electric burnishers, electric sewing machines, etc while at the minimalist end of the scale a box cutter, a little glue, straight edge, some tap water, carpenters hammer, rivet setter, and a few copper rivets. kgg
  7. Thank you. That makes things a lot easier. kgg
  8. I just picked up a 1949 vintage Singer 29k - 71 in decent enough working condition complete with original stand and flat bed attachment. I will be starting the process of cleaning / oiling etc. Has anyone converted their Singer 29k -71 to a 135 x 16 needle system from the 29x4? This would make life a little more simple as only having too have one needle system that is interchangeable between my other machines. kgg
  9. This maybe the norm in India but obviously there is little regard for workers health and welfare. Just not worth the price savings. I agree. kgg
  10. What are you planning on sewing? The 8700 series are drop feed machines not a walking foot machine and made more for fabric sewing. kgg
  11. Have you spoken too or emailed the vendor with some pictures? I would send it back and get a refund. kgg
  12. Some of us come from a generation where "common" sense was common. Today it seems to be in seriously short supply. kgg
  13. It really doesn't say much for their quality control which in turn would also make one wonder about their manufacturing process quality controls. Hope they send a replacement with safer packaging. Hope the deliver person is OK. kgg
