Hi My daughters for school have been given a quizz for a crossword but this is for jumbo thinkers and we are allowed to ask for help.
The question is
What is the only tool that can reproduce itself?
I look forward to your answers
thanks Toni

A male
Fire.
A stamp?
Number of letters?
Any letter clues?
OK with none of the above:-
FIRE
Cheers,
P
:D
no clues given at all., answers will be given some time during the week but we trying to figure out as many as we can!
Toni
A flint knapping stone :wink:
A worm
A screw
A lathe
Watson. YOu got it. I just found out from our teacher. We sent in metal lathe and that was the answer I was just interested in what other ideas.
Toni
G'day Toni,
I must have read the same books.....
Rubbish, how can a lathe reproduce itself? Go to your shed and how a look now. Do you see 2 lathes?
Nup. 6 of the bloody things. Must be time for another cull... :p
Exactly:) Only self-replicating machines in robotics can. The teachers got it wrong:wink:Quote:

yes i must agree i am not in total agreeance with the answer though. but it did acheive what he was doing the kids did do research to try and solve the answers. so that was a bonus

Yup not possible, tell me how a lathe could make a lathe bed?
Or cut the drive gear teeth... how about a mill?
I'll beg to differ. I reckon I could turn all the components, from suitable woods, to build a passable bush lathe. A treadly, of course, as I've yet to master the art of turning electrical motor windings. :D True, it wouldn't last long, nor be very durable, but it would be good enough to make another bush lathe on.Quote:

Hi
References to Lathe here are SPECIFICALLY to METAL lathes!Quote:

IOW you can use a LATHE to MAKE a LATHE :2tsup:
A drill press cannot make a drill press, a Milling m/c cannot make a milling m/c etc, etc.
A METAL LATHE is THE most versatile machine tool there is.
If you have a metal lathe you CAN make ANYTHING else, albeit small perhaps, but you CAN make it. You can use a lathe to make a drill press, you can use a lathe to make a milling m/c - in fact you can of course mill and drill in a lathe etc, etc. :2tsup:
ALL engineers or machinists find out this fact (normally) very early on in their training or apprenticeship. I found out when I was eleven (58 now :) ) and no, it was not child labour :U My (technical) schooling in the UK taught fitting and machining from age 11.
While there are CNC milling machines, you will find that MOST CNC machines are either lathes or some derivative such as a "vertical" turning centre, ie a lathe on end :)
Look at this and tell me that the LATHE is not the MOST versatile machine tool! I could not believe my eyes when I saw this CNC lathe *TURN* hexgons, rounded rectangles and SQUARES on round material - a fantastic machine :2tsup:

Sure, this is a big step up from the ordinary metal lathe, but it does show the versatility of the lathe.
So what happens AFTER the CNC lathe has milled everything? how is it assembled? by the same lathe?Quote:

HiYUP POSSIBLE, ALL possible. The lathe CAN do this. :2tsup:Quote:

Lathes CAN also cut gears. :2tsup: This can be done in several ways, here is one example, shown cutting a worm gear.
http://www.bedair.org/Worm/Worm.html
If you try to use the casting issue in defence of making a milling m/c, DON'T FORGET you STILL need the lathe to turn the shaft for the milling m/c and to bore such things as the bearing holders etc.
The lathe REALLY is the most versatile machine - see my other post for more info :D
You can't make a TS with a TS, but you CAN MAKE a TS if you have a lathe. Think about it, if you own a METAL lathe, you can (within reason) make anything else you need. Drum sander, planer, jointer, TS, jig saw, mitre saw etc, etc. You may not necessarily WANT to make these tools, but with a LATHE you could! You CANNOT use any of the other tools to make a lathe or any one of the other items I mentioned, but a LATHE CAN MAKE A LATHE :2tsup:
We're not talking about the ability to also assemble itself, but the fact that a lathe is the only tool able to reproduce its parts, or parts that can be used to assemble, ie MAKE a lathe. NO OTHER machine type can make its own parts that can be used to assemble another of its own type.Yes, the point was being able to make it's OWN components.Quote:

Have a greeny, Toni.
I haven't seen anyone open such an enjoyable can of worms that doesn't involve politics, religion or sharpening in a looooong time. :D:p
Yep Skew, Toni does need a greeny for the provocative start!

I beg to differ on the mill, they can bore and do shaft work.
I reckon the first paragraph on that wiki page Lig posted sums it up fully,
"A self-replicating machine would need to have the capacity to gather energy and raw materials, process the raw materials into finished components, and then assemble them into a copy of itself. It is unlikely that this would all be contained within a single monolithic structure, but would rather be a group of cooperating machines or an automated factory that is capable of manufacturing all of the machines that make it up."
He he lets have a little quiz, to post you must include a machine to continue the process of making the machine!
I'll start so we'd need a
1. Core sample machine/rig(must find the materials 1st)
I still like 'Fire' the best. :2tsup:
This is a pic i like.
Machine 1 builds machine 2, then passes the components to machine 2 to build machine 3, then machine......................... Just goes on and on.
It is a router table. You use your router table to make another router table.
Or is it a router? Me started with 1 router and now me have 5. :oo:
Or clamps, they are still breeding. You put 2 clamps together and ... :D
Or router bits, bandsaw blades, ...:U
Coathangers do that too. :oo:Quote:

I was thinking a toadstool - they constantly reproduce through spores they release!:p
Hammer.
I can go out to the smithy, pick up a hammer, take a bit of metal, heat it up, and use my hammer to make another hammer.

In James Naysmith's autobigraphy, he described how he made his first metal lathe using his father's lathe when he was about 12, then proceeded to make other lathes for sale. He made better lathes which then made milling machines etc., and his business grew into an industrial empire. The interesting point he made later is that all this multitude of larger engineering machines were the progeny of his first lathe, direct and indirect descendants! I love it, especially when you think that so many of these early machines went to factories that in their turn developed the great British industry of the Victorian era...and onwards. And many times removed, had a part in your lathe at home!!:D
Cheers,
This is a bit late, but how about a "toadstool"
:rolleyes:
