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!!!
The easiest way to get it right the first time is break off a piece of the pipe and take it into the store. Someone there will make sure you buy the right size fitting. Don't use teflon.
3 4 Copper Compression Fittings
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
I would just tell her the truth. Sit her down and have a heart to heart, tell her that you love her and that people are born with quirks that affect their life, some more than others, and that it could have been a much worse quirk (give examples) and explain that you're very lucky to have such a harmless quirk and such a wonderful mother at the same time (keep reminding her how wonderful she is). Tell her you've been ashamed and didn't know how to tell her and were scared that she would think you were crazy and kick you out or something, and it's really been bothering you to not be open with her and you hope she will accept you for who you are. Then offer to do the laundry that you'll create, and you'll rinse the chlorine out so it won't lighten your clothes.
What it sounds like is that you're in completely over your head. Most all pipe is measured inside, steel pipe, galvanized or black is referred to by that measurement whether you're talking about the pipe or the fittings, as it's all threaded to fit together. Rigid copper pipe is measured by the inside diameter, which comes in 1/2, 3/4, 1, etc. When buying compression fittings to join this type of pipe, you must add 1/8 to that measurement to allow for the thickness of the sidewalls of the pipe. They measure 1/16x2 1/8. So for a 3/4 rigid copper pipe you would need a 7/8 compression fitting to go over it, a 1/2 pipe would require a 5/8 compression fitting. If you get the right size fitting it will just barely go over the pipe, sometimes scraping the sides a little. The ferrule, (the tapered piece that fits inside the screw together pieces, will also be quite snug). These pieces must be absolutely straight and tightened down very solidly in order not to leak, however, if done correctly they make a very easy disconnectable joint that doesn't require soldering knowledge or experience when doing minor plumbing repairs. I use them all the time in my business and seldom have any problems at all with them.
