DIY Bottle Filler?

I fill, cap and label my own small paints (craft/ceramic).  The bottles range (in volume) from 1/2oz - 8oz.  The most common, and the one I'm most concerned about speeding up, is the 1/2oz bottle size. I currently use large ketchup/mustard bottles, which means I'm continually re-filling those bottles for any given batch I'm filling. I've been trying to figure out how I could create my own DIY bottle-filler, as a commercially-available, bench-top filler is several thousand dollars. What I've envisioned up to now is some sort of air-tight container to hold the paint with an air-compressor (at a very low pressure, but enough to push  the liquid through when gravity won't) connected at the top and a tube connected at the bottom.  At the other end of the tube (to be held by the user) would be a nozzle with a release valve of some sort. Anyone have some more technical thoughts on how I might achieve this contraption?

Water Bottle Raft

Finished Project - https://www.instructables.com/id/Project_rRaft_Building_a_Raft_out_of_Water_Bottl/After thinking about Reishee and his island, I asked my mom if I could build an island from water bottles...the idea was rejected. I asked my mom if I could build a raft, and she said sure...so i've started collecting water bottles. Not only does the final result get me excited, but people's responses do as well. Of course there are those who think i'm crazy (as there are with any of my schemes), but there are so many more who just love the idea, and get enthralled in it. A friend in crew is going to empty the boat house recycling bin for me, a teacher told me that the recycling bin in the teacher work room is over flowing, many more offer to collect water bottles from their families, and bring in the 20+ bottles from their cars. I bring a bag to school to collect them, and collect bottles from people...just being a part of this great recycling project (I want it to be 98% recycled) excites people, so when they see one person donate a bottle, others will hurry to finish their water and donate it to the cause as well.The whole thing has just opened my eyes to how many bottles are thrown out, instead of being recycled...it's amazing. Just because people will probably be asking, this is my plan:Two large water bottle pontoons will be on either sideA wooden frame/deck will be clipped onto the pontoons via eye bolts and carabinersHomemade oarsThat's the basics...I hope to have some luxuries too:Big ole water tight cooler bolted onto the back for storageTwo stadium seats bolted onto the deck to sit onTo keep up with the raft, visit rraft.blogspot.com

How to coat the inside of a bottle with resin? Answered

I recently bought some resin that I was going to test a few prop pieces out with, but, being the space cadet I am, did not pay attention to the volume the resin produces, and I'm now short resin. I can, of course, buy more resin, but I had the idea of kind of cheating and just coating the inside of a coke bottle (the glass ones) with the colored resin and filling it with water to match.  Also, there is more to this. I know I can color water and fill the bottle with that to make a colored bottle. I also know I could color the resin and fill the bottle with that. However, I have an additive that I want to use that is rather pricey, so I would only like to coat the inside of the bottle as to give the illusion it is filled with liquid instead of actually filling it up with liquid. thanks in advance!

What to do with nearly 200 bottles of beer? Answered

Ok,so I have been buying this really cheap, and surprisingly good beer at Lidl called Finkbrau. The thing is it comes in a cardboard box, that contains 24 of these 0.25l bottles. http://farm1.static.flickr.com/125/402462825_e94063d969_b.jpg And I have at least 150 if not 200 of them sitting around. The store doesn't accept returns on the bottle, and I'm a bit reluctant to throw them away.Not to mention the fact that because of their unique size, the automated recycling centers like the one in the photo below won't accept them. http://farm4.static.flickr.com/3331/4641394053_cf2d8d7aaa.jpg (The IKEA logo is because you could get free coffee and hot dogs there for every 10 bottles/cans you recycled) I was thinking of making a beer table, but the problem is that they are really short, and I would have to stack a lot of them up to get a good height. If I do go that way, I'm thinking of adding flourescent water and UV LED's to make it stand out. But what other use can you find for these little bottles?

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.

Poseidon- High Powered Modified H2O Rocket

Just thought I would give those interested a sneak peak at the Poseidon's main booster module.Construction-12 x 1.25L Soda bottles spliced with external sleeves using Sikaflex 11FC.The Poseidon's booster module is not yet complete, it has another 7L of capacity to be added. The booster will then be combined with several other modules before Poseidon is ready for launch.You may also like to note the quick attach/release fin system. They are saw toothed sign holders normally found in stationary shops. They allow the fins not only to be attached perpendicular to the body, but also provide a reproducible fixing method.Although this is not my preferred method of splicing, Aircommand.com has put together an excellent tutorial which can show you the principal. My method (which I DID NOT create) involves shrinking the inner bottle with our curled lip. Air command in that tutorial reduces the outside sheath from a larger capacity bottle to suit. The method I use does not call for the use of different sized bottles or a blow torch, just boiling water. Air Commands Splicing tutorialAircommand.com

How to re use a penknife/folding pliers?

From the bottom of my toolbox I have dug out a pen knife I bought some time ago. Its a silverline micro multi tool. I never used it because although the pliers work very well the folding knives, bottle openers etc. aren't held in place by a spring or locking mechanism. Also the rotation is far too easy, and the rotation stop sometimes slips, rendering the knives, bottle openers and everything else effectively useless (i.e. very dangerous to use). As a result I will remove the assorted knives, bottle openers and other widgets, leaving an interesting space to be filled by something else. That something else cannot really be another set of metal widgets (like knives, bottle openers, etc) because they would have the same basic problems, so my question is what would you use the two spaces for? Approximate dimensions; 9x8x55 mm internal dimensions, (one in each handle) box shaped enclosure open on one side. Openings are on opposing sides of the folding handles (see the google images link to see what I mean). Two holes near the ends of the handles which currently hold the widget axle. One idea to get the ball rolling, a mini multimeter in one side, with probes in the other. I'm looking for something practical or useful, something that could be still considered a tool of some kind, but feel free to throw in any idea's you have anyhow.

What is your glue preference for 3D prints

I'm curious to find out what glue people prefer to use with 3D prints, why, and how you use it to get the best results. Here is what I've tried and how it has gone for me. E6000 - good glue, kind of messy and takes time to dry. I usually squeeze some out on some wax paper and use a toothpick to apply it. Weld-On 4 Acrylic Adhesive - very liquid, have to transfer to a bottle to use, which for me requires a dropper, dries super duper fast so make sure it's in the right place when you push pieces together, can leave a white residue if it dries on your piece. SCIGRIP 16 10315 Acrylic Cement - pretty liquid, dries fast as soon as it touches plastic, I had to buy an applicator bottle to use with it and it doesn't work so I'm not sure if I need a different bottle or it doesn't work well with a bottle. not really usable for me right now unless I can figure out what to use with it. So when I have used it, I squeeze some out and use a toothpick to apply it but it dries as soon as I pour it out. I've also tried misc super glues but they tend to leave white residue for me. Currently, I would say the Weld-On is my go-to for gluing 3D prints, but I'd love to get other people's opinions!

Seeking ideas/thoughts for fountain pen traveling inkwell

I own a certain fountain pen that fills in a special way and is best filled by using the traveling inkwell of the maker of that fountain pen-- by using that traveling inkwell, one can fill the pen with a maximum amount of ink-- filling by dipping the nib end into a bottle of ink doesn't let the max amount of ink to enter the pen. But that traveling inkwell produced by the pen maker is VERY EXPENSIVE. A guy apparently in Australia made his own and I'd like to make one. I have ideas but seek from you more thinking and ideas on this homemade traveling inkwell. [You can see the Australian's clever, simple traveling inkwell here: https://imgur.com/a/fkzTs ] I thought I'd use a straight-sided plastic pill bottle for the vessel that holds the ink and is the main part of the traveling inkwell. The bottle I'd probably use is ~ 28mm ID. I don't know what to use and don't know where to find the rubbery "plug" into which the section of the fountain pen is pushed before inverting the plastic bottle to fill the pen. [The section of a fountain pen is the part that one holds when writing with the pen. It's also called the grip and is the area immediately behind the nib and feed.] All I have so far: - 8.5 cm tall x ~ 28 mm ID straight-sided plastic pill bottle which has near-the-top internal threads for the cap that can also be screwed onto external threads. [I'd use the internal threads for the cap.] Requirements which have come to mind-- tell me if these are sound or should be re-considered: - Whatever rubbery one-hole plug is used, it has to yield a bit to the fountain pen section (which is 11 mm OD) when the section is pushed into the one-hole plug-- the plug hole I suppose should be ~ 9.5 mm to 10 mm. The rubbery material around the hole has to grip the section so ink leakage doesn't happen during filling. - The one-hole plug should not move downward into the ink when the fountain pen section is pushed into the one-hole plug. Maybe the plug would have to be glued in place so it doesn't move? What glue or bonding substance if that's best? - The one-hole plug would be set/glued/bonded immediately below the near-the-top internal threads of the pill bottle. - I suppose the height of the one-hole plug would be ~ 1 cm to 2 cm. - I suppose a straight-side plug vs. a tapered one would be the ideal (but a straight-sided one would, I suppose, have to be glued/bonded in place so it doesn't slip or move). - Ink leakage shouldn't occur when the section is pushed into the one-hole plug and the bottle then inverted for filling. If leakage occurs, then ink runs down my hand and arm during filling. - What kind of not-hard-but-yielding-a-bit "plug" or maybe a stopper is best and where do I find just one? [Fountain pen inks are mainly water with dyes and maybe some additives in them.] Thanks for your attention to this posting!

Just as a dense glass refracts light, the denser gas refracts sound. The mystery is why balloons filled with co2  leak down faster than identical balloons filled by mouth. Yes, there is some co2 in my exhaled breath, but it is mostly  n2,  and  o2.  I would hav expected the n2 and o2 to leak out more quickly, being smaller molecules. So whatzup wit dat?
