Portable hole?

Why a hole in the Ozone?

So I have been looking up a little bit about the ozone layer and have found that about 12% of the ozone layer is reproduced by UV rays every day.  So the whole thing is replaced in about 8.3 days.  Now I think thats a little bit shorter time-span than since we stopped our mass release of refrigerants into the air.  It has even had a bit of time to catch up.  Now if you think about it, less ozone = more UV = more ozone right?  So how On earth did we blow a hole in our ozone layer, it makes absolutely no sense.  Even the fact that some of the halocarbons may still be there makes no sense because it absolutely could not affect the ozone without reacting with it.

Drilling holes in glass

Hi all, I'd really like to work with glass objects. But I need to drill holes in glass. I have no idea on how to do this, and if any special tools or techniques are required. If anyone know anything about working with glass and drilling perfect holes (without breaking the glass), can you please instruct me on how to do this. Thank you

Deep Hole drilling

This might sound stupid, but I've been wondering, is it possible to use a gun drill on a drill press? Does a drill press accept gun drills? If not, is it possible to modify the drill press so that it accepts gun drills? How? I've used normal drill bits to make "deep"(about 4 inches) holes in metal before, but it was very, very difficult to get it straight, and the metal became hot as heck after a while, sometimes the drill bit even got stuck in the metal and it was extremely difficult to get it out. Thanks

Cutting a square hole? Answered

This is a really basic question—I have managed to get to 66 years old and still be a complete handyman novice, I have tried but my best efforts are lamentable. I think it is because I have never had anyone to show me handy things and have never asked anyone so turning over a new leaf I am determined to start making a few things instead of spending a fortune buying them and paying people to do things for me. My first project is to make a simple slide carrier and I have bodged one up in cardboard but it really needs to be in something stronger so it is rigid, metal would be ideal but very stiff board would also do if I can not cut the metal. I do have a thin sheet of aluminium, (from the casing of an old laptop) that I would like to use buy am frightened of messing up & worse injuting myself! I now realize that I have no idea how to cut a square hole in a piece of metal or, for that matter, what tools I need to cut aluminium in the first place! My overiding consideration is to be safe so I don't want to try, (what to me is a daunting task but probably to you guys the simplest of things) not knowing what I am doing. So can someone please help me out and tell me what tools I need and how to go about cutting a square hole in a piece of metal? Rest assured I will not do it if I do not think I can safely. Thanks.

Which surface do I measure for pressure? Answered

So this is a fairly simple question, but here it is:  If you have a 5" pipe leading out of a pressurized chamber with a 6" inch disk covering the hole is the amount of pressure pushing the disk down that of 5" or 6".  I am pretty sure it is 5" because it has the equivalent pressure pushing the other way outside of that diameter.  Now if the 5" pipe had a bore of 5" and an outside diameter of 6" would the result be the same?

How can I hole punch thin plastic page protectors in bulk? Regular punches don't work...?

Update: I found my answer, see comment below.  In short: I used a Carl Heavy Duty hollow-head Hole Puncher, and it works great! I've been using plastic page protectors (these, specifically) in bulk, say about 1000 a month.  However, I need them to be 8.5 x 8.5 and I also need to punch holes that are slightly off from the factory holes.  I'm basically using these as a cheaper alternative to 8x8 scrapbook page protectors (which are prohibitively expensive - say $1 a sheet or so). I've figured out how to quickly cut the pages (using a rotary cutter), and that works great.  However, I am still struggling to find a way to quickly & cleanly punch holes in these things.  The problem is that the plastic binds, stretches, and does not cut cleanly.  I need a very sharp & precise puncher to do this quickly, and I haven't found one yet. I've tried normal 3-hole punchers.  I can punch them one at a time, if I hit the punch hard, and occasionally it binds & sticks (since the plastic stretches instead of breaking and gets caught in the mechanism).  I've tried hand-held punches as well, same result.  Also, aligning each individual page is time consuming as well. The problem with paper hold punchers is that they're made for paper.  They're inaccurate, not sharp, but strong.  The cheap & heavy duty ones alike only differ in how much paper they can punch, but neither are sharp/accurate enough for thin plastic sheets.  Is there a high-quality razor-sharp & ultra-precise hold puncher out there?  I haven't seen any that look even close. I've tried holding them down & drilling them.  The plastic wraps around the drill bit and they rip to shreds. I also tried a leather punch, but the ones I got were much too dull - they just dented the plastic. The only thing that has had some success is a dremel 115 cutter bit.  That actually cuts into the plastic, and if I go carefully (eating a bit at a time) it'll go through a lot of sheets at once.  However, it's messy, takes a lot of setup, and leaves a very messy hole (all chewed up). Ideally, I'd love to line up 10 sheets or so, have a way to align them (a jig?), and then punch them all at once w/o any binding or sticking. Does anyone have any other ideas?  I've thought of melting a hole, but then the pages would all stick together.  I'm completely boggled - how can I do this?  What tool can I buy for this?  What method haven't I tried? Thanks guys!  Any suggestions are appreciated.

I would like to put a 3/4" inch hole into a big bottle cap so I can connect a water valve through the cap.  What makes this interesting is that the Cap is very thin metal, and because a valve with a rubber washer is attaching to the cap it needs to be a perfect circle so water wont leak out.  Plus, I would like to be able to mass produce this item (100 an hr), so the method needs to be quick, clean and reliable.
