Primed .22 cases?

Would the primer go off on a .22 case that has had the bullet and powder removed if you shot it with a 900 fps .177 lead pellet? Also, would it go off if shot from a slingshot at a brick wall.

Optimus Prime is made of tins

I love transformers very much after I watched the movie. So I decided to make a Optiums Prime. Last year I finished this works which had lasted two month. It made by less than 40 tins and some other things. The Optiums Prime is about 40cm high, and almost all of joints can act include neck, shoulder, elbow, wrist, legs, and every fingers

What do i add to my alcohol fuel for my flamethrower, to make the flames brighter? Answered

Hi Im working on a flamethrower which is turning out pretty well, the only issue is, since im using alcohol as the fuel, the flames are pretty much invisible, i was wondering what i could add to increase the carbon content. Normally ide experiment with adding a little gasoline, or diesel to it, but i have to be careful with my pump, its made from either ABS or PLA, and for some reason everyone on ebay who sells them are very sketchy, ive bought 4 in the past and only the last one ever arrived. Anyway, what can i add to my fuel to make its flame more visible? Fortunately my flamethrower does not leak at all so its safe to move up from alcohol to something with a higher burning temp. What can i add that will not dissolve the plastic, increase flame brightness, and not increase the burn temp too much. Before hydrocarbons, are there any salts or chemicals i can dissolve into the alcohol to do this? i beleive i can dilute the alcohol a bit with water so it will take sodium, but will that have any significant effect? The sun is pretty bright here so alcohol flames are invisible, gasoline flames however are very visible in contrast. Thanks

Do you prime/paint models before making molds for casting?

I'm working on a model sculpt that I plan to cast in resin later. It's almost finished, so I'm wondering if it's okay to prime the model before using it to make a silicone mold? Or would it be best to leave it naked, so to speak? I'll be using Smooth-On products (MoldMax 300 resin and MoldStar 15 Silicone) if it helps. Thanks!

Transforming Halloween

Ever since seeing the Transformers movie I just couldn't stop thinking about transformers. So I decided a Transformer costume was it this year. It started out as just a box and later became more elaborate and more of a car. IT IS FINALLY DONE. Took three months but it's done. Pictures of the final product is here. Today I took it to school for a contest. I probably transformed at least twenty times. At one point the tape wasn't working on the spoiler because the "haters" would tear it off. So we used a bolt instead. In the contest people were chanting my name and I won ... a cheapy blue necklace. But now whenever I was going around the block all I would hear is "Are you the Transformer kid? Transform for us". Of course I would. So if anyone has questions or wants me to post instructions let me know. The instructions will be hard because of the variety of height and weight.

3 1/2 hp B&S. Starts, then immediately stops. Answered

Once I prime my lawn mower 3-5 times to start, it starts right away. But once the primed gas is used up, the mower dies. I have taken the gas tank off, removed all the old fuel and cleaned it out with paper towels. I also took the carb off the tank and blew compressed air through all the ports I could see, which seemed to be open. I also installed a new spark plug. To recap, it only runs on the primed gas. Any help would be greatly appreciated, as I have been out of work for the last 6 1/2 months, and am trying to save $$$ by doing these things myself. Thank you in advance. Jack

Does anyone have an underground water storage system?

I have four 55 gallon plastic sealed top drums barried in the ground. They are meant to store water from my washer and rain water. I have a 3" inlet running in line to the four barrels. On the other side I put 3/4 inch PVC to an inch from the bottom of the barrel. The PVC is meant to get used something like a straw in your soda. I have the straws in line to the water pump. The problem I am having is that the pump requires to be primed to work. How can I keep it primed? It would be great if there was a valve that closed when the barrel was near empty. That way the pump would continue to pump the water from the other barrels and never loose its prime. Any ideas here????? Again, these are sealed toped barrels. I cannot open them to put a sump pump at the bottom, not to mention, a sump pump couldn't supply the pressure needed for my sprinklers. Thank you in advance for any advice! ! !

Can I use rustoleum epoxy "appliance" spray paint with rustoleum primer?

I'm refinishing my steel medicine cabinet. Its old and a little rusty in spots, so I sanded it smooth and removed as much rust/old paint as I could. I washed it down, let it dry and gave it two coats of Rustoleum "rusted metal" primer in the can. I also purchased a few cans of Rustoleum Appliance Epoxy Spray paint. However, I didn't note that in the instructions, it says "priming is not recommended".  I already have the cabinet primed and ready for paint at this point and would like some imput on putting this epoxy over the primer.

How to Build "The Extra Investigator" aka "The Ed Box" Device. Will be featured on new Amazon Prime show. Will Pay for Build!!

Hey Im looking for someone that can help me build an older paranormal device called "The Extra Investigator" aka "The Ed Box". I can't find the right build for it ANYWHERE and only have one pic and the device details, this device is not used by "television paranormal investigators" any longer so its impossible to find any for sale or even other pics of this devices other than the one posted below... it has EMF detection, IR detection and detects "physical events', which i don't understand (BS basically) but it basically is an EMF detector that connects to the compass and points to the em field. Also, Im not sure how the IR detection is utilized. I have not seen this device in action, so this is what i'm assuming because of other gadgets with similar applications. I have found ways to build an EMF detector and an IR detector, I also have tons of parts, bread-boards.. everything needed for the build (have the enclosure and compass on the way via mail) but I need guidance in the build or it built for me. I understand that most serious builders don't believe in the applications of these devices but this is for a serious project and want to show this device on an episode of our new show, also they (the builder/helper) would get a shout out on an up-coming Amazon Prime show, along with payment for the labor and any parts i cant supply (paranormal engineering position for our team may open up if things work out. We are searching for a smaller company/engineer). But! ANY help would be appreciated! No need to make jokes and point out what i've obviously stated, if you cant or don't want to help, pls keep your negative comments to yourself. This device is also going to be a teaching tool for kids ages 12-16 who are interested in the paranormal and want to learn the basics. I wanted to show them some devices they wont see on TV. I'm under no illusions that these devices are 100 percent accurate and will not waste time with non-believers. This is a business situation, the build shouldn't matter. Thanks science peers

In the US, what do you call the board or panel used as bulletin boards? Answered

I'm thinking of the kind that is very easy to push thumb tacks into.  It has almost no structural integrity - very easy to break corners off.  It's more of something to go over a wall to push pins into.  It's not a foam product - definitely wood particles.  What I've seen and used in the past was primed on one side.  It's similar to what ceiling tiles are made of - but 4x8 and maybe 3/4 inch thick.
