I really wish I could justify the cost of a 2000w laser cleaning machine.

I've priced them out for projects before. The ones I was looking at were around $250k. I'm sure you can find them much cheaper now. They would be amazing for rust removal. If you had a welding shop where you had to clean up a lot of steel I bet something like that would pay for itself quick enough that it might make sense to buy it.

It cost me $2K for the last sandblasting job on a trailer. it took 2 men 5 hours to blast it. and nearly a ton of sand. The problem is if I had to do this on a regular basis, I would have to worry about sand disposal

So what if you could do the same job with 1 or 2 men in 2 hours using no blast media. If you did a ton of trailers that laser could become an attractive proposition. I was looking at cleaning big stainless forming plates but the client didn't go for it.

I would need to be present at a real time live demonstration.
However, I am thinking about possibly leasing one like this on a trial basis

Oh that's just the cost of a good welder. That's not bad at all.

I am wondering if the power supply couldn't double as the source for a laser cutter. Since it also mentions engraver, it got me to thinking that changing the burner torch out for a cutter head on a CNC table. Even if it were double the price, it would be justifiable

Backyard Scientist did a video on these things about I'm about 99% sure they can do double duty as a laser cutter.

Would CO2/dry ice blasting work for rust removal? It's great for removing other material from metal I have no idea what the machines cost, but they don't leave media behind - only the removed material.
