I used a jig saw to rough cut within 1/4 inch, then a router to fine trim after installed. The router was more to deburr than anything else, I cut it pretty close with the jig. For smaller pieces after I had broke down the 4x10 sheets, for the tongue box and such, I just cut it with a table saw.

I use an air powered shear(Harbor Freight)...an electric will work nearly as well...you can cut a pretty fine line, I usually cut within 1/8" and then a router setup to get that fine line...be careful however you go(especially a saw) to avoid scratching up the finish on the AL.

Scratches, yup. I cut from the back side so the scratches are hidden, or blue paint taped everything before I cut.

All this talk of power tools is making me jealous.

All I have is a carpenters hammer with a broken claw and rip saw with a bunch of missing teeth.

For the Aluminum cuts I am going to use my wife's kitchen shears. Ssshhh, don't tell her. I'll put them back when I'm through.

Thin aluminum can be cut with a shears, but I find it much easier to use a power shears. I have an air powered one. For tight turns, etc., I use a nibbler. A fine toothed blade in a skill saw will also work. Saws, and nibblers will leave lots of bits about. Vacuum them up with a shop vac before tracking them around. They will embed in the soles of shoes. While they may help with walking on ice, I'd bet a skinning would come after walking on the linoleum.

I use a straight edge and a scoring tool (Olfa laminate scribe - http://www.amazon.com/OLFA-1090486-Plas ... a+laminate) to make long deep scratches....it takes several passes with good pressure then bending back and forth to snap it off...but I get an edge that is close to a shear.

This is used for aircraft construction, definitely higher quality needed than for a teardrop skin ;). Cheap too....just take your time...

I'm going to give this a try. I would suspect it will only work on the harder materials. I am using 6061 in a T6 hardness so hopefully it will work.

Knife, jig saw, rotozip, all work well, and the most awesomeness tip I got right here on tnttt, if using a jigsaw, rub the blade with bar soap numerous times during the cut.
Almost 30 years working on trailers and I consider soaping the blade one of the most valuable things I HAVE LEARNED ANYWHERE !!!
A bar of soap has become a constant fixture in my tool box
If it ain't broke, fix it till it is
