jig saw on coro?

[chrisatpsu]

i bought a jigsaw tonight to use on coroplast for intricate cuts, curves and stuff like that.

bad idea? or we'll see when i try it?

btw, i picked up a 28tpi blade. It was the most teeth I could find.

I have used a jigsaw to cut out some 14 inch snow flakes. I cut eight of them at one time by stacking eight sheets of coro together and screwing them together with drywall screws( screws were outside pattern).  It worked. Not as nice as dmoore's CNC cuts. A little bit hard to separate them because they seem to melt together. 15 minutes to cut and 30 minutes to separate them. Although cutting eight at a time saved cutting time. A rough on edges but not noticeable when standing 5 feet away in a lit room. Definitely not noticeable in the dark mounted on the house.

did you use a fine toothed blade?

[dpitts]

Yes. i used a fine tooth blade.

What about using a wood template and a razor blade? I buy razor blades by the 100 pack at Wal-Mart. It'd be one at a time but no melting. Wouldn't be easy to do tight curves though

I haven't tried this but what if you put a piece of cardboard between each of the sheets of coro - to keep them from sticking to each other when cutting - you might not be able to do 8 at a time but more than one and they should separate easily.

 A Rotozip works really well for fine cuts. Just make sure you use the right bit .

[chrisatpsu]

rotozip, is that the same as a angle cutter?

I have been wondering if anyone has tried a Oscillating Tool on corro?

I don't think it would melt the plastic like a moving saw blade does.

I've tried using a dremel. It does not work well. I then switched to an exacto, easy to do, but my cuts were not perfectly straight. Good enough, and no one will see slight deviations from the street.

The rotozip works with the proper bit.  I too tried a dremel and I too found it did not work too well The rotozip works on many different materials, but it is key to use the right bit.and put clear packing tape on the feet ( to aid in a smooth slide )

The reason that the Dreme didn't work as bcause you had it spinning to fast.  A rotozip at max speed is about 1/2 of what a Dremel spins at.  Slow down the dremel an it should work just fine without melting the plastic.
