  • 5 Dollar, 1/2 Hour Worm Composting Bin(s)

    That's great, thanks for letting me know! It's gratifying to see that after so many years, this Instructable is still being appreciated. You might put a mineral oil or some other non-toxic finish on your lid so that it doesn't warp, and eventually rot. Or you could just wrap it in plastic.Please post more photos after you have had it going for awhile!

  • How to Service a Sewing Machine

    How did you do with this machine? (approximate age, make and model information are always helpful :-)The first thing to do is check the strength of your thread, if a firm, steady pull breaks the thread easily, try a different, stronger thread and see if that helps.Next, make sure that the machine is threaded properly, and that the thread is pulled into the tension discs all the way. (pull gently on both sides of the thread until you feel it go it). Improper threading is the most common reason for thread breakage.If the machine is very old, it may take a different size needle than modern machines do. See the manual, or online references to your particular machine for confirmation. If it worked fine earlier, and is having trouble now with the same size needles, it may be something else.Make…

Improper threading is the most common reason for thread breakage.If the machine is very old, it may take a different size needle than modern machines do. See the manual, or online references to your particular machine for confirmation. If it worked fine earlier, and is having trouble now with the same size needles, it may be something else.Make sure that the thread is going through the tension spring properly. When the machine is running, the thread should be pulling against the spring. If you're not sure, you can probably find the threading diagram and manual online if you don't have a paper manual.--Are you using a sharp needle? They do wear out. If there is a burr on the end of the needle, it's time to replace it. If you hear a thunking sound when the needle hits the fabric, that's a telltale sign that the needle is dull.If the eye of the needle has a sharp edge, it can also break the thread, but that's less likely than the other potential causes.Is the bobbin area clear of debris and any broken needle ends? Try removing, cleaning and lubricating (lightly!) the bobbin race. There are tiny slots cut in the race that often fill with lint and should be clean.
