Water Bottle Cutting Fun!

I was quite intrigued by the cutting competition events after seeing the link posted by Resinguy. I thought that the water bottle cutting looked especially fun. After I got home from work I decided to give it a try with my FABM. Took out some bottles and went out to the yard but couldn't find a nice platform with the correct height. So I made due with a square water hose container that was about 18-20" tall.

On the first try I only put out one bottle. The FABM sailed through it like butter :D

So I decided to line up as many as I could on that platform in a straight line which turned out to be 5 bottles. Took a big swipe and severed 3 bottles on the main body and the 4th one right at the neck and cap area. The 5th one was knocked over because the thickness of the neck and cap slowed down the velocity of the blade too much.

Took the 4th bottle with the severed head and tried to cut it again with only about 2" of water. This resulted in the bottle flying about 10ft away and part of the body severed off. I learned that the bottles really need to be full and capped. The weight and the cap helps stabilize the bottle and contain the water and pressure during the cut. Without the water and cap the thin bottle wall would just collapse and give way.

It was whole lot of fun so I thought that I would share this learning experience ;) I think I did ok considering that it was my first time and that the platform was way too low.

Here is a pic of the FABM with the 4 severed bottles.

We need vids! That sounds like a super fun test.

Next you need to fill the bottles with diet coke, drop in mentos, cap them really quick, and see what happens. :thumbup:
 
Yeah the vids would have definitely been cool. Unfortunately, I was by myself and it was already dark outside. Will definitely do a video of it next time ;)

(hogfbmle, factory edge. I would have thinned it out considerably if it had been resharpened, but it was a pretty good edge out of the box)


woulda been 7 had I gotten that last one all the way through, instead it hung on by about an inch of aluminum :(

It is very hard to get a straight line out of your swings, much harder then you'd think. I wish I had gotten to do another series of cuts with the ak47. I think that after 2 or 3 tries, I could have gotten through as many as 12 bottles. the first try I did, I tried a one handed back slash like the one in the above photo, but I very quickly realized that you can't apply force doing a slash like that, and the bottles give a lot more resistence and bounce back then you'd expect. I didn't get to try a forward right to left 2 handed grip slash, but I wish I had.

having a remote shutter with a continuous shooting option on it is very very concenient :D
 
LVC,

Wow that is a really cool shot :cool::thumbup::thumbup: Nice cutting you got going there. Were those cans unopened or were they simply filled with water?
 
Putting this on my desktop!:thumbup::thumbup:

is that a giant monster enery drink in with the PBR?:cool:
 
I have a set of LVC's shots saved to my fave pics. Simply Awesome form! I believe the blocking that the cans were on, were freestanding on the chairs as well. Now that is a clean shot.

Ban, that is some cool fun. Now we need video.;):thumbup:
 
ah, I see.....just exactly what I had in mind. I'm looking for a super cheap user CGFBM, then get it full flat reground to around 3/16" at the spine, tapering to 5/32" at the tip, and thinned down to about 0.045-0.050 just behind the edge, lol.......

btw, this will void the Busse warranty. The guys doing serious mods like this have faith in the properties of the INFI, and will avoid chopping bricks with thin edges.

They were just opened and filled with water

I really needed to move to the right as I swung, because in the stationary position I had a really hard time compensating for the depth of my cut (making it go straight, rather then shallow at the beggining, deep at the center, and shallow at the end). and I needed to correct for my tendancy to raise my cut at the end :(

If I had had more time, and a better garage where I could really use the equipment I had to thin down edges I could have done something really amazing. I swear I could have done 20 bottles with the ak47 If I had sharpened it, and I had some practice behind me. I just needed a thinner edge, and to push cut through them, rather then to try to let the weight of the ak47 do all the work (because the bottles resisted way to much. you just end up knocking them into each other if you "baseball bat" them).

the bottle cutting was done on a flattened out car spring :rolleyes:... If I missed, I would have ended up hitting a chunk of annealed 5160... That block of wood, albiet that it wobbled a little, was way stronger comparably :)

bottle cutting if fun :) It teaches you a lot about swing form, object resistance, speed, power, follow through, grip strength and rotational body mechanics.

Yes, guys like me don't really worry much about the warranty. I have tried to take INFI to the limit in terms of thin geometry and yet still be strong enough to stand up to heavy chopping.

My FABM is .030 right behind the end. The spine starts off at .210 just forward of the ricasso and distal tapers to .20 in the middle of blade followed by .140 about 1/2" back from the tip. So it is a very slow and gradual taper.

LVC,

I just checked out the previous thread and those pics are awesome man :thumbup::thumbup: As mentioned by someone else...great cutting form also. I need to get praticing.
