Design for drive system

I have ran into a issue with a project that i cannot figure the best solution for. Here is what i am trying to do. Imagine a pvc pipe setup in a ladder configuration. On top of each side of the ladder system an aluminum angle rail runs up and down each side. On top of this rail system is another square pvc piece with ball bearing mounted externally allowing the pvc square to ride up and down the rail. My issue has come from automating the pvc square to move back and forth on the this rail system. I thought of using a dc motor driving it to each end where a switch would be contacted to reverse the motor in the opposite direction. The issue is getting a motor that has enough torque to move the pvc square with about 10lbs on top of it maybe less and to do this a fairly slow motion. I had thought of maybe using a cheap 540 rc car motor, but this is where my ? comes in. How do i drive the square with the motor with out getting overally complicated. Would i be able to adjust the speed of the motor with a potentiometer? If so would i be able to keep the torque or would that reduce too? Finally is there another option that would be simplier to exectue?

how to make a waterproof switch for a minisub? Answered

Right now, I am in the process of building a small tethered submarine that is only about 1 foot long. There will be an external light module on it. So far I have a cluster of LEDs and a 9v battery holder that are both waterproof, but I do not have a way of turning the lights on and off that is waterproof. Does anyone have any suggestions on how to waterproof a switch or where to buy a waterproof switch?

Hello, I would like to know if anyone has any advise about building a 3d printer with 1/2 inch pvc piping. The pipe will be used for the rails, because they are cheaper than metal rods. I want to modify t connectors so that they are what slides along the pipe.The pipe will be parallel, and held together by right angle elbows. I will mount it on a flat board. Is there any problems I may encounter? Thanks for any help.

Fluid dynamics: can you connect 55-gal barrels in series to lawn sprinklers to circulate and keep emergency water fresh?

I saw several Instructables about how to use barrels to collect and store rain water.  It doesn't rain enough where I live for this to be practical -- however, I have five blue 55 gal barrels that I use to store water for emergencies. I would like to hook all these together with PVC and run my lawn sprinkler system through them, so that the water stays fresh and drinkable. As it stands, I have to store the water with bleach, and dump it all out every 6 months and start all over again. Big waste, and a bigger hassle. Often as not, I am sitting on 275 gallons of undrinkable swamp water at any one moment in time! -- My question concerns the physics surrounding the fluid dynamics. Is this workable -- running PVC between each barrel in series? -- or does that reduce the pressure to zilch at the end, so pressure wouldn't be high enough to water the lawn and garden? Would you have to put a bleeder valve in the top of each barrel so you could completely evacuate all the air? I really hope someone has actually done this, so I don't waste my time and money making something Mr. Wizard would just laugh at!

Gluing PVC sheet: Can you identify 'this' glue? Answered

I am gluing black pvc sheet - I presume its pvc, although not 100% certain, it has that distinctive 'new beach ball' smell to it.  I'm prototyping right now, and I want to do more stuff like this - and will likely post an instructable - trouble is it walks a fine line of 'family friendly'/sfw. Either way; I used Lepage Flexible Plastic adhesive.  It worked quite well, and has proven to be quite strong and flexible so far...Works like a contact cement, but stays very flexible.  No mention on the packaging exactly what type of glue it is though.  My question:  What type of glue is this?  Characteristic acetone volatile smell, works like contact cement.  Package says apply, let dry to touch ~10-30 minutes then close surfaces.  I find it's dry to the touch within a minute or three. (extremely dry climate + warm room I was working in). Rationale:  It's expensive, 4 bucks for 30mL, and I'd rather have a can-container to dip a brush in.  At the hardware store they have plain-ol contact cement, but the transparent/flexible aspect of this is must. Thanks in advance!

Suggestions for bonding PVC sheets to ABS sheets, for composite armor?

I have a crazy idea for making tough plates out of thermoplastics. Does anyone have any ideas for bonding PVC to ABS plastic? Two materials will add to the strength and durability of the plate. If possible I would also like to sandwich some kind of fibers in between the two plates, such as carbon fiber. Does anyone have any ideas on this? I was planning on heat forming the sheets, then maybe pressing them together at high heat, but an easier method would be appreciated.

>_< Specifications... i needz them.

So... about six months ago i moved into  new place.  it's great, but the previous tenants kinda trashed the place.  they left loads of rubbish around and were generally horrible to the house.  The previous tenants did leave a few things that are kinda nifty.  First, they left tons of PVC pipe. i have something like 20 ft of 2 inch pvc pipe, 15 ft of 3/4 inch pvc, and 10 or so feet of 1.25 inch pipe.  the second thing they left was an above ground water filter.  The owner's manual to the pump can be found here online:  http://www.pooltoysource.com/images/pdf/RVR005.pdf This got me to thinking i could setup a little hydroponic rig in my house. I have a hallway window which i'm too cheap to buy a blind for, and letting a bunch of plants cover it over appeals to me.  However, there's some problems.  The owners guide is critically lacking in any sort of technical specifications and all the info on the web just relates back to the pool pump being used as such.  Sooo... if anybody knows anything about what kind of performance can be expected out of this little dandy, let me know.
