    Global makes what seems to be a Bernina 217 clone with a cam reader. The video in the link below shows the machine sewing multipoint zig-zag stitches.

    Here is a link to the zz-217 Service Manual that shows a picture of one of the cams, that might be compatible. Perhaps you might try contacting Glogalsew.

    Instead of Kevlar thread, you could use PTFE thread which is heat resistant to about 500° F. As for locking the stitches, At the end of the run, leave several inches of thread. Tug the thread on the under-side and pull the top-thread through. Tie off the two threads with a sheet bend or surgeon's knot. A square knot can be used, but a sheet bend or a surgeon's knot is more secure.

    PTFE thread is quite slippery. A more secure method would be to leave even longer threads but do not pull through. Thread a needle on each and sew several stitches back through the same holes in the seam, essentially the same as a manual saddle-stitch.

    I had a Bernina 217 with a cam reader that I wish I'd kept. The original cams were steel, but I found an after-market for some kind of plastic-like cams that worked quite well . Most of the cams are decorative-stitch cams, but there are two cams you might be interested in -- a three-point two-stitch zig-zag and a four-point three-stitch zig-zag. Both are used for sail making. I'll try to find and post a link to the vender later.

    I had a few manuals that went with the machine -- Adjustment Manual, Instruction Book, Owner's Book, and Parts Book. I had scanned the books and if you're interested, send me a PM with your email address and I'll send you copies.

    Mike01230 provides a link for open- and closed-end types of zippers. The choice it seems to me often depends upon the application. Sailright describes these kinds of zippers as finished zippers and continuous zippers. Most of your our applications are different than typical Sailright applications, but the principles are similar, and Sailright has some videos you might want to view.

    I've sewed with both and much prefer the Juki. The Juki is a more modern machine and is still made in Japan. That model Consew was made in China, but the quality of the Consew I used seemed OK.

    A big difference for me was the difference between a top-load and a bottom-load bobbin machine.

    I've been writing an industrial sewing machine self-tutorial, and copied below is that section.

    Top-load versus Bottom-load Bobbin Machine

    Vertical Axis (aka: top-load or drop-in) bobbin machines are more likely to jam than Horizontal Axis (aka: bottom-load) bobbin machines. Sewers seem to prefer the type of machine they learned on.

    Advantages and disadvantages of top-load versus bottom-load seem to be:

    Top-load:

    •  Advantages
    1. Can see how much thread is left on the bobbin without removing the bobbin
    2. Can see and change bobbin without tilting back machine
    • Disadvantages:
    1. Must hold thread when stating sewing to avoid jams
    2. Must remove fabric to change bobbin

    Bottom-load:

    • Advantages:
    1. More tolerant to lack of holding thread when starting sewing, which means that bobbin-wrap jams are less likely
    2. Can change bobbin and resume sewing without removing fabric, especially useful when binding
    • Disadvantages:
    1. Cannot easily see how much thread is left on the bobbin
    2. Must learn to load bobbin by feel or tilt machine back to see and load
    • Other:
    1. Uses a bobbin case, which might be an advantage if bobbin tension is changed frequently and have separate bobbin cases set for different tensions.

    Apologies for the formatting. Copy and past didn't work very well.

    One kgg suggestion is a Juki DNU-1541S. If that machine interests you, you might want to also consider a Juki DNU-1508N. The primary interest when I bought the 1508 was marine sewing applications. In addition to marine canvas, cushions, boat blanket which is quite heavy and some sail repair, I have also sewed leather and fabric bags.

    The 1508 is top-load bobbin machine, which I prefer. The 1541 is a bottom-load bobbin machine.

    A difference between some machines you're thinking of is top- vs bottom-load bobbins -- the Consew machine is bottom-load. I've used both top- and bottom-load machines. Here is what I've learned or read elsewhere:

    Vertical Axis (aka: top-load or drop-in) bobbin machines are more likely to jam than Horizontal Axis (aka: bottom-load) bobbin machines. Sewers seem to prefer the type of machine they learned on. My preference is top-load, but then I first started on a top-load machine

    Advantages and disadvantages of top- versus bottom-load seem to be:

    Top-load:

    •    Advantages:

    -    Can see how much thread is left on the bobbin without removing the bobbin
    -    Can see and change bobbin without tilting back machine

    •    Disadvantages:

    -    Must hold thread when stating sewing to avoid jams
    -    Must remove fabric to change bobbin

    Bottom-load:

    •    Advantages:

    -    More tolerant to lack of holding thread when starting sewing, which means that bobbin-wrap jams are less likely
    -    Can change bobbin and resume sewing without removing fabric, especially useful when binding (sewing fabric advantage)

    •    Disadvantages:

    -    Cannot easily see how much thread is left on the bobbin
    -    Must learn to load bobbin by feel or tilt machine back to see and load

    •    Other:
    -    Uses a bobbin case, and this might be an advantage if bobbin tension is changed frequently and have separate bobbin cases set for each tension.

    I've had both a Bernina 217 that could also sew 2- or 3-step zig zag and a compound walking-foot machines, originally a Singer 111W155 and then a Juki 1508, used almost entirely for marine sewing applications. The Bernina 217 was useful for occasional sail repair. Were I to have had only one machine, it would have been either of compound walking foot machines.

    BTW, I've also used a Consew 206RB-5 sewing marine canvas and vinyl extensively for about two weeks and was less than thrilled compared to either the Singer or the Juki.

    Could the problem be that the machine had been unused for a long time and is gummed-up? I bought a used Bernina 217 zig zag sewing machine in excellent condition but that apparently had been stored for a long time. Zig zag worked erratically. A sewing machine repairman soaked the machine in a solvent -- kerosine maybe -- and the sewing machine worked perfectly.

    A few other folks on the forum seem to have had similar problems Try the following in google to see those threads.
