Q:I am working on a project with unbuilding a LASER lightshow-style projector. it is a class III b laser rating, with the following specifications: Wavelength/power: 532nm / 50mw (Green), 650nm / 100mw(Red) I may end up accidentally looking directly at the beam (although I certainly will be trying not too) I understand this laser is capable of seriously damaging my eyes if they are unprotected, so what eyewear should I use for these wavelengths? or would a weilding mask work just fine? that s about all I ve got in terms of serious eye protection, though i may just go buy something else if i know what to get!! thank you so much for your help guys!!!

Typically all water heaters are fitted with 3/4 nipples and fittings,from what I can gather you are talking about a flex hose supply line. On the inside of each end will be a neoprene washer or rubber washer,when you say still spinning it sounds as if this may be missing. Also use pipe dope as oppsed to teflon, Hope you get this solved, if all else fails take a piece you are connecting to, with you to the hardware store

AVOID copper fittings. Butane fire on copper gives bad, bad, bad gases. Look for brass usually machined. Look at first 2 pics on the left [ link below ].

If you don't want to cut a brass screen, go to a head shop where they sell black-light posters or incense and ask for a brass screen.

Sounds like you have water in the lines while your soldering .. If the pipe is spitting / bubble the joint you need to drain the system before soldering . If it is a place that's has access to it you can solder union in . DO NOT USE IF ITS IN THE GROUND OR BEHIND A WALL . IF the water wont stop try shoving bread in the pipe . Anyway all the above post are also great ideas good luck

Q:I'm out there running the weedeater, with safety goggles and earplugs so I don't go deaf, and while doing the sidewalk, this young woman jogging and pushing her baby in a stroller runs RIGHT BY me (2 feet!).Dust, grass and a few pebbles are flying everywhere! Now, aside from the fact that she is an idiot, what are my (and her) legal rights? If she or her baby were injured, would that be my responsibility (New Jersey) ? I suppose, given the litigious nature of the US (and NJ), that I am probably responsible, but wondered if anyone knew for sure.Thanks

I've often wondered that too. I'll go to the nearest fire hydrant and find out !! lol!!
