Coil spring powered hidden blade mechanism

Just some video of how the coil spring / lazy tong hidden balde works. with some epic bakground music thanks to the great Theodore Shapiro.

One, it is not a coil spring, it is a spiral spring. Two, curse you I was just thinking of using it a couple of days ago, but chose to see if there was anything on it on youtube. Yes, late, but I got into the AC games late as well. FYI. The scissor jack and spiral springs work nicely though, but I do have to ask, how did you make the spiral spring? Was it hand made? Or where was it purchased?

@jobzombi I know it's not a coil spring, It's called a clock spring, or like you said, a spiral spring. I got mine out of an old broken lawn mower. It's the spring that retracts the pull starter thing. You can also find one in those retractable dog leash

[multipleman03]

Where did you get the parts for the scissor jack?

[abonude]

@multipleman03 I made them from scratch. Sad to say but this project has been abandoned.

[loonymiko]

may you provide the place you obtained your coil spring?

[abonude]

@loonymiko

haha yeah it's from a lawnmower. It's the spring that keeps the ripcord all wound up. I don't know here to get one anywhere else.

[Stijning]

You stole my idea! just kidding xD, but I had exactly the same idea, but I kept it for myself and the Order. What is wrong with you, this is supposed to be a secret!

BRO! THANK YOU! FOR GIVING ME AN IDEA! :DD

@abonude why you abandoned the project ? from what i could see, the coil /clock/ spiral spring could alow the blade to go in and out automatcally...so wh???

[GallopingConch]

@abonude You say this was abandoned? I think it could be a really good way to make a fully spring loaded hidden blade. You could have a locking system pulled by a string and ring like in your other build, and two separate notches along the blade for where it needs to lock in. One notch far up the blade, for the closed position, one notch at the end for open. Then after oh so many pulls, you would need to rewind the spring to get new tension. But with some genius, it could work.

@loonymiko this might be a little (ok alot) small but one way i got a spring thats like this was breaking open a tape measure roll. the ones that are in a flat cylinder and retract when you press the button.

[warkilwar]

what screws did you use for the scissor jack? im making an original hidden blade from assassins creed's concept art and blueprints, and modify it to a working one cause the concept they have has some flaws :)

[mrnumber90]

Where did you get the scissor jack from or how did you make it btw I love you hidden blades Im having trouble making my own

[jobzombi]

I have to ask, where did you get the housing for the spring, or was it fabricated by yourself. I plan on probably making my own if I cannot find one with a diamater that suits me, but wanted to find out if brazing should hold just as well as welding? I'm assuming that the spring force is not that great to break off the piece using brazing.

[jobzombi]

@AlexMercer17 I think this is the closest. The trouble is seeing that there are three pieces and the blueprints, yet the possibility of using a scissor jack all the way front without being seen in the 2nd piece might mean that the force of the spiral spring is strong enough to just shoot the 3rd piece, the part with the blade, all the way out and lock, from out of view, or the piece is internal, which is harder.

[jobzombi]

@abonude Thanks, I was looking into just that myself, but wasn't sure if you got it from the starter pull as well or somewhere more practical. I obviously want a pair and to find two old mowers with the same spring will be tough, so I'll see if I can ebay it for cheap. Thanks and really looks good.
