I have a sheet of copper that's 1/8 inch thick or a bit less. Can I safely cut that with a bi-metal blade on a bandsaw?
Thanks

The speed of most one-speed bandsaws designed for woodworking is too fast for effective metal cutting.
Can you cut it? Yes. The bandsaw blade life will be shortened some, depending on how much copper that you cut, but you can cut it. Use a fine tooth blade. You can have similar results using a table saw for any non-ferrous metal by using a high tooth count carbide blade. Cutting metal on a powered saw requires more care and safety equipment than when cutting wood. Wood sawdust isn't hot when it hits you, but metal chips are going to be very hot. Full frontal protection, leather apron, long sleeves, a face shield over your safety glasses, gloves, etc. are a must. A foot switch, for when things don't go as planned, is a good idea too. My son and I have a welding/fabrication shop. In it, we frequently cut even mild steel up to 1" thick using a specially modified table saw or band saw, with a special metal cutting carbide tipped blades, and we do this safely. We've been doing it for the past 5 years.
For a small amount of copper or aluminum, a carbide or hardened high tooth count blade will work fine, but expect the blade to dull faster than when cutting wood. Follow the personal safety equipment guide lines above and you will do fine.

I have the Evolution 14” metal chop saw and love the darn thing. I am considering purchasing this Evo saw for corrugated and sheet. I think the tracks on my FEstool would work here. Not to ride on, but against. Not cheap, but neither is material today.

A 14 or 24 TPI bi-metal bandsaw blade should be fine for 1/8" copper sheet. Alternatively, a non-ferrous blade in a table or miter saw would also work.
I would disconnect the dust collector

Always use the word "impossible" with extreme caution
I usually use jigsaw with a proper blade for metal cutting (steel, aluminum, etc), if that's an option for you a lot cheaper to replace a jigsaw blade...
How about a saber saw with a metal-cutting blade and proper speed selected?
Also, it would be quick and easy to make a temporary table surface if you have to.
Copper sheet is a pretty soft metal. 1/8 sheet will cut pretty easily with most woodworking saw blades. Higher tooth counts will give you a better and more controllable cut. Good eye protection is a must.
You can cut non ferrous with pretty much any blade you have in the shop. A finer toothed less aggressively hooked blade will feel smoother and not grab as much. Lubrication is your friend, as the metal likes to cling to the blade. Blade speed isn't an issue with nonferrous metals. Just like wood, adjust your feed speed.
Thank you so much for the excellent responses. I hadn't thought of putting wood under it, that makes perfect sense. Thanks again.
It will be gummy and may clog the teeth similar to pitch in wood. Is it hard or annealed?
