A completely spontaneous and unplanned construction. I wanted to make a model of a regular chainsaw for some time, but I didn’t have any idea on how to build the blade until recently. When I got the blade to work, the rest followed in just a couple of days.
The blade is basically a 1 stud thick layer of bricks. On the tip of it, there is a 40t gear with no apparent means of support. Between it and the blade, there are two freely rotating 8t gears that let the 40t gear roll on them. The 40t gear is pushed against the 8t gears by the chain – so basically the whole blade is kept together by the tightness of the chain.
The saw is loosely modeled after some standard Husqvarna machine. I did not calculate its dimensions, it was built just roughly. Inside the saw, there is a single PF Medium motor powered by the Lego battery. The battery can be turned on or off by a trigger inside the saw’s rear handle. The speed control system implemented in the battery is utilized as well – the speed can be controlled by a lower grey gear on the saw’s side (the upper gear is just a mock-up). The saw was extremely fun to build, but doesn’t really cut well. Firstly the plastic chain was simply unfit for cutting, and secondly it tended to come apart when pushed against some hard surface, which resulted in the 40t gear falling off immediately.
ilove the chainsaw its unique and kool!!!
I really liked this enough to make my own it’s cool too

Doom 3 menu theme.
@Sariel great build, what song did you use in your youtube video for this? your stuff is amazing to say the least
@Sariel
You still need to, at the very least, learn how to actually hold one 😛
wait forget i said that and by the way sick model
do you think you will start making instructions like nico71 does
@johnny nashawaty
No.
hey could you make a vid totorial of how to make it
@gimba96
Who would count that?
how many pieces o chain have you used?
When I was 9 I would have tried to cut my sisters up in tiny pieces and probably came after Paul because it wouldn’t cut, NO BLOOD. Builders !!! Don’t try this at home…while your parents are around. Hehehaha
BELT SANDER! then you can race it!
Get out of town. Looks so real. Can’t wait to show this to my cousin. He will freak out.
and its heavy too

The only thing with NXT is the fact that the NXT Brick is so hugh – I’m building something at the moment and without the NXT I would have no problem building it, although I need it to control 3 extra motors and the PFs with my other NXT as a remote control.
Overall, it works well if you have room for it.
@NxT bUiLdEr
I don’t know, really.
i am building with lego mindstorms and you should try it! but do you think you can help me with my every day legoing? (sorry my “i’s” aren’t capitalized)
@legokid
miscellaneous
Hey what dos misc. meam?
@bobsurankle
No, I just have strong associations between chainsaws and blood 🙂
Wow, fantastic. But did you really have to put all that blood every where?
@Murcielago53
Yeah, I guess so. Only after this one was complete I realized how little I know about chainsaws 🙂
Anyway you could hook it up so that the trigger isn’t an off/on switch, so when you hold on the trigger the chain runs, and when you release, it stops. This is more realistic, and more fun for revving.
Amazing job, the aesthetics are great and its functions are impressive, especially the speed dial, you always half to go the extra step, eh?
Men you are the BEST.
Great imagination…..
Really nice looking. I like it alot.
Fond memories of Doom chainsaw… ;o)
Excellent!
With Halloween coming up in 3 weeks, don’t let any Bionicle creatures see you with this chainsaw! They’ll freak out! 🙂
lol very nice saw but a little bit n00b
łał pierwszy raz widzę coś takiego!Gratulacje za pomysłowość
I already commented on the video on youtube as v4trogaSci =D
But still, I can’t resist saying that it looks great, and the details are cool, even if it is a “roughly” built chainsaw. =D
@RjbsNXT
I didn’t count but it’s probably over 100 chain links.
try cutting styrofoam
I love the design and its realistic look :O
How many chain links were used??
Also I like the way you used the speed control on the new rechargeable battery pack .. very clever 🙂
I know you’re good with photo editing but the blood and hand prints on the chainsaw is ingenious 😉
