LSZ-1 Portable walking foot Upgraded

[kgg]

I had a special need for a small footprint machine and table to do basically one function in a particular location and at a low cost. I decided to get a portable walking foot machine and build a small table. The machine is one of the Sailrite clones so it is the same as the Reliable Barracuda, Rex, Consew and Omega to name a few. The job of this little machine is to do edge binding with either spools of raw edge binding or short lengths of binding with V92 thread. The Warlock purple color is to protect the innocent and is just some purple car wrapping I used.

The problems I needed to solve:

1) Have an almost full industrial size table in the least amount of space.

Solution: Build one. A standard table is 22"x48". Mine is 20"x47" when the 17" extension is in the up position. Which should I ever need to install a servo motor there is space.

2) Have quick access to such items as scissors, needles, bobbins, screwdriver, seam ripper, etc.

Solution: Design and build an Accessory holder for the left side head cover and one for the top of the machine. That lead me down the rabbit hole as the Sailrite has a real metal front but an Aluminum top cover while the look a likes have Aluminum front and top covers. So I had decided to a version for:

i) the Sailrite that uses real earth magnets

ii) flat faced machines like the Juki LS-341 and Juki 1341 and clones

iii) side mounted one that uses real earth magnets for the 441 style machines like your Cowboy's, Cobra's

iv) The version for the Sailrite look a likes required the Accessory Holder to be mounted to the left side head cover.

3) Have quick access to the left side head parts for oil and not having to remove the cover as those tiny little screws always go on a wonder.

Solution: Design and build a whole new left side head cover that had a hinged door that would accept an adjustable angle (horizontal to about 25 degrees) Accessory Holder

4) Fix up the clumsiness of having to reroute the top thread to the bobbin

Solution: Remove the top carry handle and utilize the existing holes to mount the modified top / bobbin thread guide, install a thread guide pin and replace the tiny screws with thumb screws. Never like the handle even when I own a Reliable Barracuda, the tiny hinge screws are, I think, just not strong enough to support the weight of the machine for much abuse.

5) Replace the cheap top thread guide with a proper one.

Solution: Remove and replace the guide with a proper one.

6) Get proper height distance from the top of the thread spool to the machine guides.

Solution: Install two thread spool holders under the table for both the spool height clearance and space savings on the table top. Route the threads up through the table to both table mounted guide rods. The purple one is one I made to look close to the original.

7) How to contain short lengths of edge binding rather then having it drape to the floor.

Solution: Design and build a large binding bobbin, bobbin holder guide that can be quickly installed on the front edge of the table top up to about 2 1/4" thick. My design can be used with domestic, portable walking foot and flatbed industrial sewing machines. I also designed and build one for cylinder bed industrial sewing machines.

8) How to wind short lengths of edge binding.

Solution: Design and build a binding bobbin that can be wound by hand or using either a domestic bobbin winder or a industrial sewing machine winder.

9) How to use the cost effective spools of raw edge binding up to 2" wide.

Solution: Design and build an adjustable spool platter with a bearing that can be quickly installed / removed on table tops up to 2 1/4" thick. The platter can accept up to 2" wide spools of raw edge binding up to 14" in diameter.

10) Getting the stitch length back to the same length after doing a reverse stitch is near impossible unless you always return to the max. stitch possible.

Solution: Design and build a new stitch length guide. I could have bought the Sailrite EZ for $49.95 but that required the existing stitch length threaded level to be remove, a new longer one installed and re-adjustments. So I made a simple one that just requires the old stitch level base to be removed and install a new one, about two minutes work.

All the upgrades are designed and built in Canada. These and others will be available shortly on my website: www.warlockdesigns.com email: parts@warlockdesigns.com

Question are you inventing new parts just for the joy of it and are they really that useful?

Both, as two of my hobbies are sewing machines and 3D printing. The parts I come up with speeds up the process by adding convenience and functionality to the process which makes it more enjoyable as I can concentrate more on the task at hand.

Impressive! Putting the thread spools below the table is an interesting idea.

I'm waiting for you to make a complete sewing machine with your 3D printer.

Okay Smartie! LOVE the thread holders below the table! Mine always get in the way mounted in the usual manner on top of the table. I have done other things too when I didn't have a thread holder, like just sit one on a shelf above me. that works. But I like your idea best because it all stays on-board. Great! Love all the your ideas and the purple is fun too!

Thank you. under the table for the most part is underutilized and to mount them on the table top would have been a waste of space and to get the proper 2 1/2 times the height of the thread spools would have put to much of a downward angle in the thread path.

If I win the lottery I'll buy a metal 3 D printer for that project.

I am with you on this mostly but I have to say this new idea for holding my bobbins I am very happy with. I have done a few 3D printed bobbin holders but I don't like them on my table top either and with different machines I have in the past had to get loaded bobbins from different machines. This one gives me 19 pairs (38 total) of bobbins hung conveniently close and easily moved from one machine to another. Taint pretty being wood and nails but here it tis -  Hangs on the thread stand.

May not be pretty but it is functional, inexpensive and convenient. Which it is all about.

And... If you have an intruder, you can smack him with.  It might not disable him but he'd be easy to identify.

Cool idea there Rocky! You guys are such inventors! Yes, very functional. You don't have to dig around in a drawer while the thread unwinds. Drives me crazy! Oh and the leather knot hanger thing - rustic!
