cutting thin copper sheet
I have a project that entails cutting thin copper sheeting.
There are small radii, too small and tight for snips. I was thinking about using 2 pcs of plywood to sandwich the copper with. Has anyone had experience cutting it this way ? Is there a metal cutting blade for a scroll saw ? |

A woodworking blade should be able to cut thin copper. Sandwiching it
sounds like a good idea, assuming you use 1/4" or less plywood, although probably not absolutely needed. Jess.S wrote: I have a project that entails cutting thin copper sheeting.

May use a gauge tomorrow to check it. Ideally, a scroll saw would be nice, but I'm not sure if there is a metal cutting blade to use. |

A scroll saw/jeweller's saw will work just fine - been there, done that (used to cut out blanks from copper sheet for enamelling). Make yourself a base out of a wee board with a keyhole shaped cutout (hard wood) that you can clamp to a table or screw down on a bench, then cut the copper on that. No need for the sandwich. http://www9.yatego.com/images/415d0d...chen-klein.jpg http://www.gerstaecker.de/Laubsagetischchen.htm -P. -- ========================================= firstname dot lastname at gmail fullstop com |

All you need is more teeth per inch and more time. What is wrong with a metal cutting scroll saw blade? http://woodworker.com/cgi-bin/FULLPR...3&LARGEVIEW=ON I used to have some metal blades for my ancient Delta. They might be around somewhere. |

For simple round holes in thin copper, you can use a punch. Don't have one? Make one. Steel tubing of the appropriate size, sharpened by tapering one end with a grinder or a file. -- Regards, Doug Miller (alphageek at milmac dot com) It's time to throw all their damned tea in the harbor again. |

Could you not get various sizes of square tubing and grind an edge on all sides so its razor sharp and then use it as a punch to cut the copper through? If the copper is a bit thicker than a manila folder, then I figure it is between .020 and .060 inches thick. That is going to be a tough punch. Them figures are not that thick and give you 100to1 it'll cut through copper plate/tin of that thickness. Copper is an easy material to cut and dent. -- Sir Benjamin Middlethwaite |

cutting thin copper sheet
I've done some really intricate patterns in thin copper using a bandsaw with a thin blade. Enclosed cuts were done on a scroll saw. If you are making multiples of the same pattern, a sandwich is the way to go. I found that I could make a sandwich with four sheets of copper and five sheets of luan/doorskin/etc. My favorite way of keeping everything together was using a low grab spray adhesive like 3M 77. Coat all surfaces. If your pattern is delicate, don't pry the sandwich apart. Instead throw the sandwich in a container of thinner and let the thinner dissolve the adhesive. Works like a charm.

Cutting thin metal on a scroll say is common. Blades are commonly
available. http://www.mikesworkshop.com/blades.htm wrote in message oups.com... a scroll saw would be nice, but I'm not sure if there is a metal cutting blade to use. |

If you go with the scroll saw wood blade, and don't sandwich the top don't use a blade with reverse teeth. regards John ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ THANKS TO ALL WHO RESPONDED WITH IDEAS ON CUTTING THIN SHEETS OF COPPER. The sheets are .025 thick. . . I found a source for metal cutting blades. May go with that. This is a great forum. Just when you think you have seen and done it all, someone comes along with a new idea and way of doing things. Smitty |
