We just got an 80W CO2 at the space. Apparently if you replace the compressed air assist with pure oxygen it can cut steel like a plasma cutter.  Also, the laser tube looks scifi as all hell and glows when it is firing.

I'll get a video of ours this weekend. This is the same style tube being test fired by some guy in his kitchen. The green is the coolant line that goes through the tube and connects to a chiller. https://www.youtube.com/watch?v=03u-r1KW2LA&t=97s Also, to keep with the thread, this is what happened to our previous 150W laser after it left our space (owner moved). Someone turned off the air assist as it was cutting, and no one was monitoring it.

Comment from a friend whom I showed the video to: "This guy is clearly not married" CO2 lasers are infrared, so you can't see them and don't know if your eyes have been exposed to dangerous levels until you start to lose your vision. Simple polycarbonate blocks the radiation though, so it's not hard to be safe.

My eyes always feel funny after watching our CO2 laser cutter through polycarbonate. Is it just because the burning material is so bright?

This one is just as unsafe with the added bonus that it is 100% home made: https://www.youtube.com/watch?v=5Td7cSgg6IA It looks like such a Rube Goldberg machine. CO2 from mixing baking soda and vinegar? Check. HV transformer output shielded by a pill bottle? Check. 2 AC pumps in series to pull a vacuum? Double Check.

Here's a bargain on eBay... https://www.ebay.com/itm/High-Value...=item258e4f2a28 Part of me is tempted to see if they'll actually ship me this for free at this price. The other part of me thinks it's some kind of elaborate phishing scheme.

Do it. Just fund the transaction with a credit card so you can reverse the charges if you get scammed. Shipping poo poo from China to the US is stupid cheap, so that part could be legit. $180 for the whole machine however is pretty suspect, since a decent laser tube costs 3-5x that alone.

Wiring loom coming out with the engine, that's a first. You're lucky you don't have to crawl all over the engine bay disconnecting plugs behind the manifold and poo poo.

Every engine I've ever pulled the harness disconnects from the main body harness with a few big plugs and comes with the engine. Even my 1986 Celica is designed this way, although it's considerably harder to reach the big plug (behind the blower for the HVAC  ).Also, what InitialDave said.

I've worked on many, many, many cars that you have to pretty much unplug every sensor on the car to get the engine out. There are also others where they get so close to making it unplug to remove, and then they'll have like three wires coming out of the main loom that go through the firewall just to gently caress with you. Also you often have to dismantle fuse boxes to free the engine part of the loom from the car. On a semi-related note, on friday I discovered that in the BA falcon ford decided, in their wisdom, to rivet the engine ecu bracket to the left hand strut tower. Also that holden decided the best way to affix a window regulator to a commodore is with loving rivets so if your window motor fails, you're using a drill and a rivet gun. So stupid.

Also you often have to dismantle fuse boxes to free the engine part of the loom from the car. While I haven't pulled an engine in ages (and certainly not on my current car), GM mounts the ECU for my car... under the hood. From what I can see, it's one plug to disconnect the entire engine loom (except for the alternator, starter, and grounds). I was impressed/surprised when I saw that.

My '97 Probe (aka MX-6) was the same way, so many wires and vacuum lines that had to come off to get the drat thing out.

Normal tires don't blow like that, but those marks sure look like a tread pattern. Bets on the driving wheel curbing something and getting a nice sidewall bubble and them putting it in the backseat?

That looks like one of the kinds of vehicles where the seats fold down to let long objects go through the trunk into the back seat area. Like, for instance, skis. With how everything is torn it makes me think the tire blew up in the trunk and the burst of air blew all the foam and upholstery off the seat frames in its haste to reach the open atmosphere.
