"Coping saw"-like holder for abrasive cord?

[gomipile]

Does anyone make a holder for abrasive cord that looks and works like a stiff coping saw/jeweler's saw? The type of cord I'm talking about is Mitchell Abrasives silicon carbide abrasive cord and similar.

I could make a holder like this out of a jeweler's saw, but I'd rather buy one that's proven if there is such a thing.

Jewelers use that cord for some inside sanding tasks in pierced work. We just tie a knot in the end, stick it in a drawer and close the drawer, and hold the other end in our teeth or tie it to our belt....really.

Any method of keeping the abrasive cord taught works. The only fixture I have seen was two narrow slits in small boards (3X6"),with these boards attached to the ends of a 24" 2X4. You stretch the cord between the ends, with the slots holding the knotted ends.

And what's wrong with a jeweler's coping saw? Just about every one I've seen would not have a problem clamping abrasive cord...you could probably adapt a carpenters bow saw if you need a longer length of cord...but Stacy's got the right idea...little tiny bits of abrasive wear out quickly on most materials, you want a method that's not fiddly or time-consuming when it comes time to change out the cord. A piece of plastic or a green sapling bent into a bow shape with some notches cut for the cord might do the trick

You are overthinking this.

If you want to use abrasive cord to sand and polish inside some area, making it overly taught in some sort of frame is counterproductive to the effort. Either use a simple method to hold the ends, like I described above, or hold the cord in your hands....which is the most common use method. Clamping the metal piece in a vise and gripping the cord in both hands will allow you to articulate the cord where you want it to go. I have never seen a tool that was more agile than the human hands- especially when combined with a well trained eye.
