    I need cool, simple metal working projects for high school students

    As the title says, I need some simple, cool projects to excite high school kids and get them interested in working with their hands. I have a very limited shop. No tools other than hand tools. I am trying to buy a small lathe, but not sure if it will get passed my small budget.

    A co-worker of mine suggested buying a hand pop-rivet tool and making stuff out of sheet metal. We have a sheet metal supplier need by and I may be able to get somke freebies or scrap. Any ideas on simple projects we can do with limited tools? I can buy some small hand tools such as a pop rivit tool or something else. If I get the lathe (small grizzly bench-top) I am thinking of small turning projects such as chess pieces.

    I also have a mold to make fishing lures from lead. I have a hot pot that I could use to melt lead or puter. We also have a CNC machine that we built that can cut wood and plastic (maybe soft metal, haven't tried). I just want to start building a strong hands on Tech program at the school I teach at. Right now we have a weak "hands-on" tech program.

    Any suggestions are welcome, even if the are "outside the box"


    Thanks,

    Mike

    Mike, I don't think its lack of interest that's held back responses, its' just not being inundated with ideas given the limited resources you've got,at least thats my excuse. there's stuff you can do with hand tools, and benchwork is an important part of it, but most of this work would be the antithesis of fun; at least for a 15 year old. a program teaching scraping or filing hexagonal holes probably isn't going to cut it

    fishing lures is a good one, isn't there some metal to use other than lead though? toxicity of fumes etc, I'd check that out before using it. sounds like the CNC has potential, even if its engraving their names in plastic or aluminum key chains.

    aren't there companies targeting schools around robotic stuff? maybe not kits, but close to, sort of heavy duty mechano. thought i saw that at a school. anyway, something like that that involves a bit of electronics and not much machining might work and robotics is popular.

    It will depend a bit on your budget but if you can get a conduit bender, otherwise known as a Hickey I think, for 3/4" thin wall electrical conduit you can use the conduit to build the frame for a "soapbox derby racer".

    It is possible to build almost the whole thing and if you do it completely with Ackerman steering (Google that) you can also use it to illustrate some principles of geometry. Getting ambitious you could probably fabricate suspensions systems as well and if you can get old bike parts you could probably make pedal powered racers.
    An open mind is a virtue...so long as all the common sense has not leaked out.

    I missed metal shop at my high school by one year. They used to cast, turn, weld, and mill, but discontinued the program and turned the room into a tech room.

    I took a class my freshman year called "Industrial Technology" and it was in the wood shop. We did some light woodworking, sheetmetal work, and small engines. We made a toolbox, which required a brake, shear, drill press, and a spot welder. Not sure how much these cost exactly but maybe harbor freight might have some deals on all in ones? We also made a funnel and used a roller to insert wire into the rim. Lawnmower engines were fun, and readily available the day before trash day during the summer. Have them in groups and take them apart.

    Some of these suggestions require more tooling than you may have, but nothing super expensive like a lathe or a mill. Hope it gives you some more ideas anyways!

    I was trying to think of what I liked to do when I was 15 and one thing that you may be able to do with your limited resources is messing around with bicycles. I used to cut up old bikes and make lowriders or frankenstien looking things. If you go to a local junkyard you can pick up old bikes for a couple of dollars and round tubing for a small price as well. all you really need is a saw, files, and a brazing torch or welder. Another thing that I made at that age were body lift kits for trucks. all they are are round or rectagular disks or tubes with a hole in them and maybe a way to align them. Im not sure if these are good ideas for you or not, but it interested me at that age. good luck!

    I would suggest the idea of making model siege engines as used during the times of castles and knights. Simple bent sheet metal and wood. This would let the kids "throw" something with the machine. Another cool thing idea might be marble runs. Use two parallel metal rods to let the marbles run around track. That really uses the imagination, kind of a "Rube Goldberg" thing. Here's a link for the marble idea; http://www.eddiesmind.com/ Another way to get them involved is to make money. Maybe start a small production line making bird feeders, or something for them to sell and put the money into a Friday afternoon party, or put the money back into the shop.

    I almost forgot one of my favorites, Mousetrap Cars!!! Should be able to do most of the work with utility knives, hot glue, and erector set parts. You could even use your CNC to cut out custom wheels and frame components. Students could do these individually or in teams, or maybe use a rat trap as a class project. There are tons of websites out there. Our project had to carry a pop can and use one mousetrap. I think it went almost 30m down the hall...

    CO2 cars are also a possibility. Search for the "F1 Competition."

    www.f1inschools.us/item.asp?itmID=4

    The cars are cut out on CNC machines and raced on a track. I think it's bigger in Europe, but I know for a fact schools in OH have participated. Part of the project is a presentation including a display board.

    I get requests from kids of all ages for personalized signs. This might be a longish project but it would not require any new tools. You can get local shops to help out and in return they get to prospect for future employees.

    Contact a couple of mid-sized signshops in your area that do electric letters. Ask them to bring along some examples of can letters, LED & neon, and maybe a small cabinet. Look for one that has a portable Tig that will come to your school and show the kids how the process is done - maybe allow them to try a couple welds.

    Ask all of the shops you contact for any scrap opaque white acrylic, aluminum, and jewel-lite trim. Youll get some ugly colors but the kids can repaint them to whatever they want.

    Using pop rivets, double sided tape, scrap vinyl or even screws the kids can make simple shape cans. If you have a metal bender thats great - if not you can bend the .032 aluminum on the edge of a table with a hammer.

    Cut the Acrylic with coping saws to simple shapes that the kids design themselves. Get the sign guy to show you minimum radiuses for the trim cap.

    The kids can use colored transparencies, paint directly on the acrylic or put photos on the acrylic for the designs. If you keep the cans to less than 11" x 11" so that you can light them with a lightbulb (another lesson plan there with donations from your local home depot) I will throw in transluscent digital prints. Provided we are not talking about 1000 kids here

    You might be able to get one of your local shops with a printer to do this as well. Remeber to start with the design first - then make the can - then cut the acrylic.

    Edit - i forgot you mentioned you have a CNC - use that to cut the acrylic faces - BONUS!

    That should give you a couple classes for the demo, metal work, acrylic cutting, decoration, and electric wiring.
    Worry about success, failure takes care of itself.

    I love the sign idea! My kids can do designs of signs, then use the cnc to cut/engrave into the acrylic. I like the idea of making metal cans to hold electrical and light the sign. I can do basic electricity, metal work, bending,rivitings, painting etc.

    Gravity Die Casting

    Machine a simple mold out of steel, either tubing with machined inserts or a solid block. Then melt some aluminum, heat up the steel mold, pour the aluminum into the steel mold. It's cool because it's a permanent mold that can be used for mini mass production. A great thing for shop students to learn. The aluminum solidifies in about a minute at which point the mold can be opened, emptied and reused.

    another idea for you

    Hello,
    I would suggest a welding program, if your budget would allow it. There is always a need for good welders, especially Tig welders.

    some ideas on my side..

    wire cars... http://sunsite.wits.ac.za/math/geometry.htm
    ---> needed -> some tin cans, some wire, some hard work

    There are also small windmills made from some tin... maybe you could include some electronic components to power a small light.
    the windmill on this page is a little intense, but it highlights the point
    http://www.indianarog.com/empiresteamengines.htm

    Also, i once made a bridge, we could make it from any material, (mine was steel), the span was pre-determined and we had to design the best bridge...
    you can build a bridge with glued sticks, strips of sheet metal, wire (suspension), etc.

    the teacher set up a testing rig, that consisted of a bolt and screw.. he would attach the rig to the center point of the suspended bridge and tighten the screw until the bridge failed... i enjoyed that!

    we also made knives, a small piece of stainless was obtained, and then we grinded the blade, and made wooden handles..

    hope this helps

    these ideas sound loads better than what we did in metal shop. we had lathes, mills, sheet metal breaks, and welders, and all we ever ended up making was bongs, pipes, and stash boxes. the real hard part was coming up with excuses to tell the teacher why we were making these things.

    but that was in my youth....

    one thing we did do (that WAS school supported) was make metal 3 ring binders (.032" sheet metal and piano hinges) and clipboards you can get the hardware for these at most office supply places or even buy the cheap binders or clipboards. we would then make the silkscreens and print names and small simple pictures on these items

    Wow, lots of great ideas, please keep them coming, school start here this week. Any simple projects for a metal lathe? I am hopefully getting a small benchtop lathe this year..I'll find out this week if I got it.

    can anyone suggest a good metal lathe for under $1,000? I have looked at grizzly, but I think it uses plastic gears? I don't want to buy junk, but I can't afford a lot, we have a tiny budget. I have a total budget of $725. I am willing to blow it all on a lathe to start building my shop up. I would even kick in a little of my own money if needed to get closer to $1,000 if need be.

    Lightbulb

    maybe fine some thing used there tons of small nc lathes out there that you can use for the year or two then invest in a cnc covert ion kit:idea:

    I don't need cnc, just a manual lathe...the used route might be a possibility, but with a school system that can be hard. People are funny about how town money is spent....pain in the _ _ _ really.
