Laser Rust Removal?
 
I was watching a restoration video on youtube and came across a guy using a Laser to quickly remove serious rust. So I was wondering if anyone has tried it with bike parts yet? And if so how well does it work with chrome and does it take the paint off?

Here's a vid of a laser in action. You will need to fast forward to 1:30

You would definitely need to know what you were doing.

It's also pretty cost prohibited, but luckily there are a few oil field places near by that use them. I am going to try and see if one will give it ago on a old bike frame I have.

It'll definitely take paint off, it just depends on how you set the laser. It shouldn't touch chrome, but it would removed degraded chrome plating. The laser is vaporizing the rust. It relies on the fact that rust absorbs of the energy, and bare steel has some significant reflection. So the rust/paint is ablated leaving bare steel underneath.

Looks like cost is a big factor, never going to compete pricewise with a wire brush wheel mounted in a 3/8 drill :roflmao:

Or a tub full of citric acid or a professional rust remover. I was just impressed by it because it's so fast and more environmentally friendly . Really I suppose it's a good alternative to sandblasting.

It's actually very cheap. It's just the large upfront laser cost. The actual operating costs are probably lower than a drill with a wire brush. And it's 10x faster with better results. For anything professional it'll the cheapest option.

For a volunteer charity shop it is out of reach even though we regularly work on rusty bikes. Would have been nice to have but the outlay makes it prohibited, rather spend our budget on parts.
