Fisheyes

I was wondering if anyone could give me an description of what a fisheye is and what it looks like. My welding instructor wanted us to look it up and try and find an explanation of it for extra credit.

I believe it is called a fish-mouth, and basically, it is a cut in a piece of material that will fit up to a tube (or pipe, depending on application) with no gaps. It kind of looks like an open mouth of a fish. Roll cage joints need to be fish-mouthed so that they fit nicely.

They make tube notchers that do this for you so that you don't have to do it yourself. I got mine at http://pro-tools.com/hsn501i.htm, but you are probably going to have to make the cuts yourself.

Thanks Mike, thats exactly what I was looking for. I did a search on their site earlier but that didn't come up in the results.

It's a good thing I'm not the only one on this board.

Now there is a fish eye too. It is that little defect in your paint job that the paint just won't cover. It is caused by oil or silicon on the surface, repelling the paint.

Too many different things called the same thing: Fisheye can also be used to describe an super wide angle lens suppossedly the photographer a fisheye's view of the surroundings. It is a good thing Mike W is here!

Also a fisheye is an auto painters nightmare, it is a bubble of moisture or oil in the sprayable material so when it comes out under pressure it looks like bubble with a hole in it.

Peace,
