It is a lot better than nothing though.
Not well but I don't feel as sick afterwards when welding on zinc. I suppose it filters some but I wouldn't count on it to really protect you.
Good eye! Never thought of using the mask for a costume! And yes breathing welding fumes is not healthy. I generally feel really tired the day after but this mask helps alleviate most of that.
Rinsing your mouth out afterwards removes most of the coconut residue and the baking soda neutralizes the acids caused by the bacteria that feed on those sugars. Besides, you get more sugar from everyday foods and there is enough fluoride in the water that extra is not needed.

The design is directional and works best pointing at something although side signals are picked up as well. As for a use, I have it pointed at a local library that offers free wifi. Since I'm in a place where the power goes out a few times in the winter (but not at the library, different power grid), I can still access the internet with my laptop in emergencies
One of the reasons I didn't use a pipe cap on the three inch pipe was because I wanted to be able to take the cover off again to access the inside. As for making it one size pipe the wifi unit is too large for the 1 1/2" pipe and the three inch pipe is too large for the original mount. You could change the design if you also change the mount. For not using a reducer I like to build with what I have on hand and I didn't have one. Of course a reducer could be used and it would be easier. This whole thing can be easily modified and made better and I'm looking forward to seeing how others have improved it.
Yes, I know the ABS isn't a waveguide, I just wanted something to keep the elements out. I've done the cantenna idea on a previous satellite dish but since I had a bigger satellite dish I thought to do it again. You are right about mounting the antenna vertically though, I just wanted to try this out. What I was thinking of doing was putting a metal cone around the antenna to bounce the rf waves at the antenna for increased sensitivity. But I guess a better way would just be to mount the wifi unit vertically and place a reflector behind that. Would have to change the mounts though and that way I wouldn't have to worry about measurements to much.
You can get increased range, I've done it with a cheap and underpowered USB dongle. Just make sure that you have a way of focusing the usb's rf onto the antenna, most likely with some sort of reflector. My design is just an idea, it's not optimal, but it does pull in a lot more signals.
I was too lazy to buy one. Besides, if I was using something else besides ABS sewer pipe, like any other kind of plastic or metal tube, I wanted to make sure this idea works for any other projects that come along.
It might improve if the antenna was upright and had a reflector behind it. I just made it this way because it was easier. Go ahead and improve on the design I'm sure you can. At some point I probably will too and one of the things I might try is wrapping aluminum foil around the tubes to help focus the radio waves.

Thank you for your kind comment. I wrote that because to me an instructable has directions on how to make it and I didn't do that here. Just wanted to present an idea that others might use.

Not so far. In fact the welder welds and feeds better than it did with a 2 lb spool. The welder is a cheap 110v and was about $199 a few years back. It is DC output though and I did replace the teflon liner with a steel one a while ago since I use mostly flux core and the liner had torn. One extra modification I had to make when moving the spool spindle back was to extend the bolt on the spool spindle because the adapter is too wide and the nuts wouldn't sit properly.
