Heavy Duty Workbench

Specifications: 60X30 Not attached to any walls Heavy duty (I need to be able to throw a transmission on it and get to work or take out my hammer and do my woodworking stuff and not have holes or any other damage to the work bench) Under $500 I have scoured Instructables and can't seem to find an instructable that suits my needs.  I can get a full metal workbench for $1500, or a metal topped workbench for about $800. I'd like to keep this cheap. I'm all good for scavenging, but I live in the suburbs, so places to scavenge are hard to come by. Regards,  David

Extract heavy water?

I can't get hold of any heavy water so I want to try extract it from normal water, I only need a drop or two. I was gonna use electrolysis to separate the atoms and increase the concentration if heavy water till it gets to around 70% (min.) but how much of power do I need to pass though the wires to only separate H2O and leave the D2O? (Need the deuterium for a fusor I'm building)

weight gain? Answered

This is just one of those strange things that flashed through my mind when I read the other question on Deuterium. Since its just water, and I don't remember ever reading that it is harmful to drink it, I was made to wonder: If a person were to drink enough deuterium over a period of time to replace all the regular water in their body with heavy water, just how much weight would they gain?

Heavy aerial lift quadcopter?

Hi, I am in a local competition where they are asking for a quadcopter that can lift a box of lead. The box weigh's 25kg. Yes, you read that right 25 kg. The rules state that it must be a quadcopter and it must fit in a meter by meter by meter cube. This limits the prop size to 500mm diameter unless the height of the blades is different so they overlap. I would prefer not to do this. each rotor must lift 7000 grams (payload + weight of quad). I have been using this thrust calculator : http://personal.osi.hu/fuzesisz/strc_eng/ and according to it a 500mm (20") at 4.5" pitch (I just put that as standard) will need to spin at 6000 RPM to produce 7.12 kg of thrust. It also says it will need an 800 Watt motor. I plan on using these motors http://www.hobbyking.com/hobbyking/store/__24433__NTM_Rotor_Drive_450_Series_1700KV_930W.html. They are 930 watts and 1700kv. they run on a 6s lipo. A 6s lipo is 22.2 volts. 22.2 X 1700 = 37,740. 37,740 RPM is the theoretical speed of the motor. I only need 6000 RPM. 37,740 / 6000 = about 6. so the motor has an 8 tooth gear on it and the prop has a 42 tooth gear on it. This makes a roughly 6:1 ratio to slow down and power up the rotor. The motor is 30A constant current, 42A burst. The ESC will be this one http://www.hobbyking.com/hobbyking/store/__25366__Turnigy_Multistar_45_Amp_Multi_rotor_Brushless_ESC_2_6S.html and the battery will be this two of these: http://www.hobbyking.com/hobbyking/store/__9176__Turnigy_5000mAh_6S_20C_Lipo_Pack.html.          When I started writing this I had a question that I answered myself but now I just want to know if you see any faults with this. PS, the winner of the competition is the one who can hover the longest. I also want to do it for as cheap as possible

Visible Gas? Answered

I wan't to fill a chamber with hydrogen, have a chamber of the same size linked with it, with a heavy visible gas in it, then as I pump out the hydrogen the heavy gas displaces it and I can see when I need to stop pumping and refill with hydrogen.  What gas can I use,  I know just about any visible gas will work because hydrogen is the lightest, but it would be nice if it was heavier than average air so I could allow air to flow into my heavy gas chamber to displace it.  Or can I just die the air with some kind of smoke from my smoke machine. Yes hydrogen is extremely explosive, so this would be on a very, very small scale with hopefully 0 oxygen.

IAC's Heavy knex Crossbow Review!!

Well here is a review of the cannon so that you know YOU NEED TO BUILD IT. Well here is a video http://www.youtube.com/watch?v=cy9SxI0I3Gc . Next comes the review. PERFORMANCE range: 8/10 75 feet not angled about 90 angled a little. ROF: 5/10 The rate is good for a cannon like thing but for every shot I would say about 7 seconds or less with a lot of practice Reload time: 6/10 about 15 seconds COMFORT Handle: 7/10 good for a cannon but there are better Stock: 8/10 Its a good stock it supportive but not extremely comfortable Second hand placement: 6/10 I feel like my hand is stretched to far when I put it at the way front of the gun and when I put it on the barrel it bends LOOKS AND STRENGTHS Looks: 9/10 well its big so already its amazing and in my opinion it looks pretty good Barrel strength: 8/10 the barrel is really strong for rubberbands but it bends vertically Handle attachment: 10/10 I can lift the gun with only the handle and it is very heavy Bipod: 7/10 Strong but not portable as said by Mr.Muggle Bow: 9/10 Very strong period Overall this gun is like 9/10. That is off my opinion not by calculation Well I'm done so now you need to go build it.

Elevator type platform for heavy, CRT monitor

I have to sit sometimes and stand sometimes to use my desktop computer. I use an old, heavy, jumbo-sized CRT type monitor which has a space-saving stand on its top for my printer. Currently, when I stand, I raise the mouse on a box and elevate the keyboard on a piece of foam and I peer downward to look at the monitor. This is not always a good way to see everything on the monitor.  What kind of simple elevating/lowering platform could be constructed so that the monitor can be raised to be level with my head when I stand and lowered when I sit in front of it? I suppose some electrically powered or non-electrical hand-cranked platform would be fine. Remember: both the motor, hardware and platform have to be able to lift, lower, and support a heavy CRT monitor which has a plastic platform holding a printer above the monitor. [Due to severe space limitatons where I live in my ultra-tiny apartment, I can't really use a shelf to hold up the monitor when I stand, and besides, it would be a pain in the neck to frequently lift/lower and set in place the monitor on either the shelf or on the desktop.] Thanks

Who's Cannon Rules----------I_AM_CANADIAN's heavy cannon rules!!

Its official, and i accept my defeat, IAC's was rated better and more people prefer it. How will it compare to my newest instructable, my HIGH POWER CROSSBOW. Whose cannon is better, My Light Cannon V2.2, or I_AM_CANADIAN's Heavy cannon V5. They are both special in their own ways. His is more powerful and flies 80 feet. It loads in over 30 seconds. Mine is a little less powerful but flies almost 150 feet. Mine loads in under 15 seconds. Also, Mine uses 8 rubber bands and his uses 16. Here is the puncturing using the same front on the ammo. Try to build them before you decide. WHOSE IS BETTER. Note-I did not fake these pictures. Try them yourself and the results will be the same. I am not trying to start a fight I just want to see whose you think is better. Note. The Video was shot with IAC's V5 and my V2.3. I just built V3.0 but did not post it yet.

Seeking engineering advice on mounting heavy weight in concrete ceiling

Hi all, I am designing/building a prop ceiling-mounted surgical arm (see reference photos attached) into a 15" concrete slab ceiling for a hospital room set for a tv show. I'm also attaching two sketches of the two different arms I plan on making and I'm hoping some of you clever engineering-types may be able to identify flaws in my schematics before I go too far with the design. If you see something that could pose a danger to the actors or have and alternative suggestion I would be grateful!!! Here are my concerns: 1) what are acceptable stresses on all joints due to weight distribution and actors moving the parts around? 2) the heavy duty industrial casters that tapcon into the ceiling: would they get pried apart as weight is applied gravitationally? 3) can the concrete ceiling handle the live stresses of actors moving the arms? 4) can the horizontal PVC arms handle the weight or do they require a welded metal skeleton? --------------------------------------------------------------------------------------------------------------------- Any feedback would be greatly appreciated; I'm in my research phase of this build now so please let me know your thoughts!!!

CLOCKS!!! how to make a.... very powerful clock?

Hey, I'm new on here but realllyyy need some help in this as I have a limited technological background. Basically I have a project in which have two digital displays, each one displaying either the time, in minutes or the hour (two digits per display). Now what I want to do with these is effectively attach these on to the hands of an analogue clock, so that when the hands spin round, the time is displayed. For example when the minutes hand is at the quarter past mark, the display will read 15 and when the hour hand is at the bottom the other display will read 06. So I have the designs ready for this clock (including counterweights and whatnot) but I just need a very powerful clock movement, or gearing system that will enable me to turn a couple of heavy clock hands, I have seen online you can but high torque movements which at the moment is my best bet, but i cant imagine it will work very well to be honest. I would really appreciate any response or something to point in the right direction as I'm very open minded and if the issue is solved, I will be sure to put up instructions on how this clock was made. Thanks for reading. Josh

According to physics, does driving with a heavy load increase traction in winter?

Many Canadians enjoy adding weight to their vehicles over the winter to increase traction. How does it work? Since friction is force normal times mu, thus having a greater force normal means more friction. However since mu is usually so small, the increase in friction is negligible as compared to momentum. The momentum from added weight, mass times velocity would be dramatically increases, meaning longer distances to stop and easier fish tails around corners. Therefore less weight is more benficial. This is my logic, and I may be wrong. I don't know, thats why I'm asking...
