Introduction: Knex Chainsaw!

Picture of Knex Chainsaw!

This is a chainsaw that I made. It go round relatively fast, because I used a strong motor. It still needs a little tinkering with so if you've modded it, or even put a gun on it (as some chainsaws now have guns) let me know.

Step 1: The Handle

Picture of The Handle

Those little grey motors are found in those little battle set things, if you don't any.

Step 2: Chain

Picture of Chain

There are exactly 59 chain links. Each chain link has a grey connector and a green rod. I used balck for sheer coolness.

Step 3: Handle No. 2

This is the handle that you hold onto. I'm right handed so I hold it with my left hand and use my right hand to operate the motor.

Step 4: Front Cog

This does occasionally jam abit, as in the links sort of stick in between the teeth of the cog. The cog is also a black/yellow one.

Step 5: The Main Bulk

This is kinda tricky to make. Follow the pictures. The third and second pictures are the body sideways on. There are only two red rods, your eyes arent playing tricks on you!

Step 6: Connections

Do as you see. It's pretty obvious what goes where, use the pictures as far as possible, but if you have any problems let me know.

Step 7: Finished

You have now a sexy chainsaw. Please dont kill anyone.

This project looks awesome but there isn't enough documentation of you actually making it to be a full Instructable. There are two things which you could do. 1) If you happen to have images of you making your project you can create some more steps, add those additional photos into your Instructable and then republish your Instructable. 2) If you don't have any more pictures of you working on your project, that's ok too. That just means that your project is better suited to be submitted as a slideshow. Your images are already in your library, and you can use the same text that you have already written for your Instructable so it should only take a few minutes to create your slideshow and show the world what you made! Thanks for your submission and let me know if you have any questions along the way.

Owenmon (author)TwistedParadox2009-03-28

Okay.

Owenmon (author)Owenmon2009-03-28

All you have to do is copy it and paste it in the search box.

DrWeird117 (author)Owenmon2009-03-13

LOLWUT?

DrWeird117 (author)Owenmon2009-03-15

I know, but...odd.

Owenmon (author)DrWeird1172009-03-16

Yes, yes it is.

JeremyHero (author)2009-08-11

nice And FlashDudes stinks as a chain saw

DrWeird117 (author)2009-01-25

Are the slate gray things required?

rathemighty (author)DrWeird1172009-06-29

you mean those green things with 4 pegs on each side? I'm wondering what they are and if they're required, too.

DrWeird117 (author)rathemighty2009-06-29

Yeah.

rathemighty (author)DrWeird1172009-07-03

K thanks

rathemighty (author)2009-07-02

I don't have the green things that you see in the first picture

j-chode! (author)rathemighty2009-07-03

firstly, they are grey not green. and secondly they can be replaced by any gearing system (red gear-grey gear-red gear)

gryphster2 (author)2009-03-15

u should mod it and make a lancer from gears of war

dsman195276 (author)2008-05-20

cool. but I see a huge problem. in the into you said that "doesn't 'go round' that fast, but if you had a better motor, it would be better.". you used the fastest/strongest motor out there...

DrWeird117 (author)dsman1952762009-01-24

The Erector motors (modded of course) work AWESOMELY.

j-chode! (author)DrWeird1172009-03-13

erect :L

DrWeird117 (author)j-chode!2009-03-13

LOL

knexguy (author)dsman1952762008-05-24

Use 12 motors and butcher your family!

dsman195276 (author)knexguy2008-05-24

i don't think that would work, because think about it this way. gears have two things: RPM and torque those things are changed through gear ratios. but the higher the torque the lower the RPM and the higher the RPM the lower the torque. if you have something spinning at 5000 RPM with no torque i could just stick my hand on it and stop it. but if i had a thing spinning at 1 RPM with 5000 torque it would not hurt me really because it would not be moving fast enough. to make a chain saw you need a very powerful motor with lots of RPM(thats our problem) by putting 12 motors on the same rod the torque goes up the roof but the RPM stays the same, so i would need to gear it down to get any RPM and then you would lose torque. also 2 more problems: i don't have 12 motors, i have 5 (but i think 3 are not working. i just barely have enough motors to build the 5 pound gatling) i don't have the grey "gear boxes". i looked and there not on knex.com or ebay.com. they must be a rare new set that just came out.

j-chode! (author)dsman1952762008-05-24

lol. that would be somin though, 12 motors...

knexguy (author)j-chode!2008-05-25

Probably heavy and awkward though.

j-chode! (author)knexguy2008-05-25

lol, sonic muscles to lift it, then you would have to slowly bring it down again, whilst cutting you familly's arm...

ajleece (author)j-chode!2009-03-01

lol, sonic muscles to lift it, then you would have to slowly bring it down again, whilst cutting you sister's arm...

Fixed

j-chode! (author)ajleece2009-03-04

lol!

knexguy (author)j-chode!2008-05-26

Lol.

j-chode! (author)knexguy2008-05-26

you could just imagine it y'know, them csi people: "c.o.d mac?" "well sarah, by my calculations i think we're looking for a chainsaw with 12 motors" "OH MY GOD!"

masterchrisx3 (author)j-chode!2008-06-22

"wonder what the rpm is"
"by my calculations *dramatic look and pause* ITS OVER 9000"

"ok nick, check all shops that sell toy motors and if you find any, check the buyers database. Oh and stay away from psychopaths holding plastics"

knexguy (author)j-chode!2008-05-27

Lol! Watching CSI now, as it happens.

dsman195276 (author)j-chode!2008-05-24

yea, it would.

I used to think those grey box were just for looks, I didn't know what they did or if they were hard to find

knexguy (author)dsman1952762008-05-25

Yeah, meant as a joke, and I know how gears work. Also, it would be simple to gear it down far enough to get a good balance.

Mike Cortes (author)knexguy2008-05-29

how would u fit them on the same rod. they have to bring a longer one out

knexguy (author)Mike Cortes2008-05-31

You "could" try linking them on in pairs at different parts of the chain.

knexguy (author)knexguy2008-05-31

Italics broke.

j-chode! (author)knexguy2008-06-01

lol, you replied to your own comment.
