Default 1watt laser for cutting blue vinyl coating?



Who thinks this laser from wicked lasers would actually serve as a good replacement for the soldering iron tehcnique of cutting the plastic away from skins? I was thinking of the reflective quality being obviously bad, but if it can burn a match stick in half........

thoughts???

I do a lot of work with high power lasers. Anything over .5 watt + reflective surfaces is bad ju-ju. I'd say stay away. Eye damage can occur before the blink reflex kicks in and you won't even know it till later.

Definitely want some seriously industrial-quality laser eye protection goggles when messing around with 1-watt laser.

EDIT: It takes a pretty deliberate effort to put your eye out with a soldering iron, and the soldering iron costs a whole lot less money than the laser and will get the job done quite well. Still, that laser sure has some serious geek-wow-coolness factor to it, and I wouldn't mind owning one myself just for that alone.

good point, it comes w/ protective eyewear- so assuming that is not the issue here, would it harm the aluminum? would the reflected laser be just as dangerous? i have zero clue about lasers, but i have a lot of vinyl to cut when my wings get here

I don't know about aluminum, but I would love to use that to start my next campfire!

Probably would not hurt the aluminum since the beam would be mostly reflected, but I would guess that it might get hot enough to set the vinyl on fire instead of just melting it, which wouldn't be desirable at all.

You would have to ensure that no other people are standing around the hazard area without eye protection too.

The laser beam would probably also be a bit more difficult to cut straight lines since you'd have to guide it by freehand. With the soldering iron, you can just simply zip the tip alongside a metal yardstick to quickly make nice, pretty, straight cuts thru the vinyl.

After taking all the time to make the neat looking stripes on the aluminum during my build then taking many scotchbrite pads to ALL of the surfaces during paint prep.....I would never waste my time cutting off the plastic again.

YMMV, it does look cool though

I laughed out loud reading the warning post....do not look into laser with remaining good eye...good one

With that said, as a repeat offender, you are going to go over the entire airplane and scuff it up before you paint so just go ahead and remove the blue plastic now. The longer it stays on the harder it is to remove plus there have been numerous people who discovered corrosion under the blue plastic after they had finished a part and left it on the rack, in the corner, in the rafters for some length of time. On the 10, as with the 7 after I was about 1/2 way through....I'll remove the blue plastic.....and not with a laser
