345 Stop watch with scales for speed measurement.
I think the watchmaker's term is "tachymetre". An old Omega catalog I have says that it is a shortened version of (get this) "tacho-productometer" ! I personally believe this to be a reverse-acronymics example, the original term makes perfect sense in French. Tim. |

The drill bit cuts out wood at the center (ejecting it through the slots up higher), and the hollow chisel bends wood from around the drill hole into the path of the drill bit, resulting in a square hole. (Usually used for mortising in things like a door lockset. 347) Used for adjusting the height of something -- such as perhaps the rear of a cannon barrel to adjust the range. 348) The business end of a Jacobs style chuck key. 349) An electric motor. The coil is suspended in the two loops at the ends of the battery, and current through the wires produces a magnetic field which interacts with th field from the permanent magnet(s) on the side of the battery. It looks as though the wires coming off from the coil are just a bit off center, so as the coil twists, it will probably lift clear of contact at at least one end, allowing it to flip around and repeat the cycle when it next makes contact (probably near the end of a revolution.) Even if the wires were perfectly centered, if the enamel were scraped off of only one side of the wire, it would work pretty much the same, with the enamel acting to interrupt the current. 350) "Slingshot" handle (not truly a slingshot, but the only term I knew for this as a kid is most certainly quite politically incorrect, so I won't mention it here. :-) It looks as though it is designed for the rubber bands (perhaps surgical rubber tubing) to fit through the two holes near the ends of the fork. Now to see what others have figured out.

349 is an electric motor What is /really/ puzzling with this picture is why the battery isn't rolling over. -- Jon Haugsand Dept. of Informatics, Univ. of Oslo, Norway, http://www.ifi.uio.no/~jonhaug/, Phone: +47 22 85 24 92 |
346. Mortising chisel for bench top mortiser. This could never
possibly work for a leather punch because the chisel only reaches full depth at the corners. |
All of them have been answered correctly:
340. Russian circular slide rule 341. Mortise chisel 342. Puzzle, remove the nut 343. Drill chuck key 344. An electric motor 345.

Isn't 349 a galvanometer ? I can se how I'd like it to be a motor, but what's acting as the commutator ? Don's guess is correct, the coil is made from varnish coated magnet wire, each of the two axles has had half of this insulating varnish scraped off, making them function as primitive commutators. I tried Carl's idea of scraping off all of the varnish and got the same results he did, it still worked. If anybody wants to make one, it works best with very thin wire. Rob |

If you have an old (and preferably dead) wall wart (the oversized lump on the end of power cords for lots of portable things which plugs directly into the wall), they normally have a small power transformer inside. You can recover a lot of wire from one of those -- in two gauges. The finer wire would be wound closer to the center, and connected to the power line, while the slightly coarser wire (probably better for this task) is wound on the outside to produce a low-voltage secondary to power the device -- whatever is is.

You can pull a few rare earth magnets from most junk hard drives.
Probably scrounge the wire too. |

Lots of neat learning stuff, including simple motor similar to this. The problem with such kits is that it is "bought magic" and impressive as it may be, it does not make the kids wonder after the show. Depends on how pre-packaged the kit is. I'm an electrical engineer, and when I was young my dad bought me one of the electronic kits with a couple of transistors, resistors, and capacitors, complete with a peg-board affair where you could assemble circuits with a type of Fahnestock clip. I had a blast with this kit, and the components later became my first parts stash. :) However, there was a contemporary kit where the components were enclosed in lucite cubes with metal ends and a schematic on top. The idea was to build circuits by joining the cubes together. Somehow this kit struck me as just Not Right. I don't think it would have held my interest as long not being able to handle the actual components themselves. I also had one of those little motor kits where you wound your own armature. I have to say I think this home-made battery bazinga tops that. :) If you just find a few items around the house and put them together, it may very well make the kids feel that the workings of todays environment is within their own grasp. (Or whatever it should be described.) Certainly not for the very young, but a great book for kitchen table experiments is the collection(s) of Amateur Scientist articles from Scientific American magazine. One of these articles got me building Van de Graafs as a kid. -- Tim Mullen ------------------------------------------------------------------ Am I in your basement?
