The aluminum is 3/16" thick. It's an extruded aluminum sub-fence so in a couple of places it is thicker. I need to make a rip approximately 16" long.

Is there anything special that I need to do to cut this on my Uni?

Or should I clamp it down and try to cut it straight with my jigsaw?

I wouldn't have worried too much about it on my old Ridgid but I don't want to do something wrong with or to this saw.

Thanks very much for yor advice.

Use a blade designed for aluminum and soft metal. I think a triple chip is appropriate, but not sure. Use a blade lube ... looks like a giant chap stick.

Wear long sleevs, and full face protection. It will throw shrapnel like you can't believe.

...and leave the DC off.

Thanks very much.

I have no DC so that wasn't an issue. I have an old Dewalt Series 20 blade that I don't use very much so I used that. Cut just fine.

Should I worry about any aluminum shavings/chips in the saw?

Thank you very much again.

If possible(depending on the size of aluminum your cutting) I double stick tape the aluminum to scrape MDF. It just seems to cut more smoothly with less vibration. I also use full face mask.

Why no DC Jim? Wont some of the aluminum shavings be sucked up when the DC is turned on later, even after a shop vac cleaning there will be a few? Are metal shavings bad for a cyclone? (I know he doesnt have one but theoretically speaking)

The problem with using a dust collector when cutting metal is the slight chance of getting hot metal into the sawdust and getting it to smolder. After a few minutes the problem goes away.

your aluminum on a band saw, in-fact I just cut some 80 x 60mm extrusion on mine yesterday and it worked great. I have cut it on a table saw before, but that was scary!

Mark,

For future reference keep these in mind, they cut aluminum, steel, wood, just about anything.

The blade is the important part. I've cut through a foot of 1/2" thick steel plate freehand using the Evolution - 180. It is nice to have around for cutting steel pipe and, threaded rod, and as per your question, aluminum.

After a few minutes the problem goes away.That's a problem with ferrous metals, not aluminum. There is nothing wrong with running a dust collector while cutting aluminum.

"That's a problem with ferrous metals, not aluminum. "

Are you sure about that?

It's true aluminum won't burn and continue generating heat like steel, but it still gets plenty hot from cutting friction.

Are you sure about that?Yes. It is a cutting action with aluminum not a grinding action. The metal flake will get warm, but not hot enough to combust.

Triple chip with a Negative hook angle is best. I spray a little WD40 or other light lube before hand. A standard ATB positive hook works fine too. Just don't push fast. Let blade do its work. Many hundreds of aluminum cuts and no problems. Joe
