Putting a blade in backward still cuts but does not bind up. I used a plywood blade smaller teeth.

Out of curiousity, why does flipping the blade backwards work?


I cut aluminum channel with my chopsaw all the time, but obviously this is not that same.[/QUOTE]

A standard woodcutting blade has too much rake on the teeth, making for a dangerous and aggressive cut. Having the blade backwards, prevents that, keeping kick-back to a minimum.
A non-ferrous metal cutting blade has very little rake on the carbide teeth, which also reduces that DANGEROUS kick-back.

At the sheet metal shop I worked in we used a hand held jigsaw. I use the jigsaw at home on aluminum and it works great. Leave a regular "wood" blade in and have at it.

Cut the 3 main pieces of the plate this morning. Came out dead straight. Used a circular saw with a wood framing blade 24 tooth, no problems. I did not turn it backwards or anything i just set the depth of the blade to 1/4" so there was nothing to even allow binding.

Jigsaw is up next... Cringing about messing up this part. As long as i get the main center piece perfect, im on track.

perfect depends on how far away you are when you look at it

Believe it or not laying down tape over the line you are going to cut makes the cut cleaner, I don't know why but it does. I just lay down tape re-draw my cut line and have at it. I prefer to use a table saw with the blade in the correct way.

Well here is what i got done today.

Very happy with my progress and how great it came out as far as the cuts. I was really worried i would screw up the big mid section and be out $100.

Cutting curves that dramatic with a jigsaw - PITA. Really likes to bind up but i got through it. Also... dangerous edges had to file those down as soon as i got home to a file.

I am currently trying to figure out how to, or find a place to put a bend in the front and back of the midsection piece for both strength and to tie into the tailgate door. One place wanted $75... for 5 minutes of their time...

Nice work. Makes me appreciate my plasma cutter that much more, that and the fact we have a water jet cutter at work.

You would like the wider black rubber edging better to control noise.
