Cutting Aluminum

I'm about to start a repair project and looking for thoughts on the best way to cut aluminum to shape before for a large patch. Thanks!

I assume you are talking about aluminum sheet. Electric Shears (nippers) if you are going to be doing a fair amount of cutting. Harbor Freight shears work good.

For large thicker aluminum sheets I have used a tool called a "nibbler". It basically nibbles out uniform notches.. You just carefully guide the tool along a clear line or arc guide and it just does a clean job with minimal edge lift/distortion.. There are hand type and electric. The electric will do an amazing job...less hand effort, but huge cost
Lift����

Cutting Aluminum

For those with a steady hand a pneumatic cut off wheel is hard to beat.

A band saw with a narrow blade can work very well too.


Gradiens super tenui glacie.

I used the Harbor freight electric shear on my project they work great.

I also used the hand shear and the hand nibblers for tight areas .

be careful

Most of the suggestions you see here will leave you with an edge which won't look good and be difficult to work with to make it look good. Any...ANY....small "wobbles" and cut marks will show. Filing to an "edge" is hard. Just measure it and take it to someone who has a shear. Now, on a small patch you can get away with those other cutting tools.

Careful use of a bench-mounted belt/disk sander will smooth out the edges very nicely.

Lots of good advice about tools and techniques on these forums. Also many good demonstrations on YouTube.

Yes, but in my experience hard to cut with a jigsaw without a lot of vibration.

You can spring-clamp sheet metal (ie., aluminum) onto a piece of plywood. Keeps it from bouncing around as you cut it. Better yet, sandwich it between two pieces of clamped plywood. Variations on this procedure are many.

I opened up the ceiling under a light in my Safari with a Harbor Freight pneumatic nibbler. It worked great. It does leave a rough edge, so if the edge is going to show you would have to smooth it with one of the techniques mentioned earlier here. In my case, the light covered it up, so no worries.

Hilti and others make circular saw blades for cutting non-Ferrous metal as well as steel. Never used one but they look cool. I will get a blade for my Festool Kapex (chop saw) but haven't needed it yet.

I have a red 10" sawblade I got at Home Depot, brand is escaping me, for non-ferrous cutting. In my tablesaw it cuts thick aluminum like buttah. It's astounding. I need to try it on the 0.032 aluminum I have.
