cutting nylon
I need to cut a gentle curve through the long dimension of several
1/2"x1/2"x1" pieces of hard nylon stock (making soft jaws for bending pliers). I tried using a bandsaw and the two pieces welded together behind the blade. Is there a lubricant I can use that will keep the stuff from melting while I cut it? |

That's water if you don't get the silly. Compressed air should also work, and be less messy (but loud). Cutting (blade speed) slower might also do it. Or, use a coping saw (which is basically an extreme case of slowing it down, by changing to a handsaw). -- Cats, coffee, chocolate...vices to live by |

Compressed air might even work and be less messy than other options. The "weld" is not very deep and can probably be split apart if you scrape the edge a bit, or if you have an edge that did not share the same saw pass. Another trick is to place a layer of masking tape between the layers where you cut through the two pieces. -- Roger Shoaf About the time I had mastered getting the toothpaste back in the tube, then they come up with this striped stuff. |

It's dangerous as hell in its solid (frozen) form, its liquid normal form, and its vaporous form.

Surprising that anyone take the risks at all in the first place but they then go on and often add an animal derived emulsion, sometimes plant derived disaccharides, then quaff the stuff in quantity. |
