Bandit Bolt "Clover Leaf design"

[outback]

Just a quick question to see if anyone has used the Angel bolt made by Bandit Bolts? I put a Bandit Bolt "N-Bolt", in My EM1, it works great.

This is the first I am hearing of this bolt. I sent an email directly to the manufacturers for more specifics:

I see how the bandit bolt can reduce chopping in a spyder/cocker designed bolt, but what pros does it yield for us Angel users?

Any more detailed images of the Angel Bolt? Different angels perhaps?

Thanks for your time,

William

I will post when I hear something. :nerd:

The Angel version doesn't have the anti-chop spring or anything if that's what you are asking. They have an open face and the clover leaf style. The only uncommon feature this bolt seems to have is the different material it's made from.

Thanks for the info. That was exactly what I was getting at. :evilgrin:

I picked up the clover leaf bolt. Doodlebug sportz in Everett Wa, is close to my home, and Don carries alot of Bandit stuff. Bandit Bolts is a mom and Pop shop in the mid-west. Talk about customer service. He gave Don a call a while back on some spyder bolts and told him to send them back because they were .002 over size and didn't want the possibility of the bolt causing excess wear on the chamber, who else would care about .002 (Human hair is .003).

I am taking it out to the field Tomorrow...If I get enough playing time, I'll give an update.


Also just for kicks here is a photo of a golf ball launched in a wind and water tunnel. You wonder why paintballs are not like bullets look at the votices coming off of the back (and how random they are). Sorry I work in the aerospace industry and this is my life. The golfball in the picture does not have spin on it...I have others which have spin on them, which would be similar to what a flatline puts out.

That's pretty cool stuff there. Any after hours testing on paintball related topics? :puzzled:

that golf ball looks cool.......at first before reading it I thought it was just a paintball with some paint coming out of it, looked at the big picture, and I was like "how the heck did that paintball get so deformed?" then I read it was a golf ball......oh well

No tunnel testing on a Pball. Most University of Washington students use the tunnel. We do alot of computer simulation. But there is no way to predict (that I know of) the settings for a fluid filled sphere, of X viscosity, combined with a deformable outer shell. Same category as a water balloon.

I did caluate the reynolds number for a Pball at 300 fps at sea lvl.

There is some interesting science on fluid dynamics and spherical objects. At medium speeds a smooth surface has more drag on it then a rough one (but not at low speeds, and conversly very high speeds). The reason is the boundary layer is thicker around a rough surface, with smooth surfaces you get separation of the laminar flow around the ball. With rough surfaces you get turbluent flow but the air "grips" the ball and thus you get pockets of air that stay with the ball for longer durations. However once spin is induced then your rough surface will create lift as it spins. And travel in the direction of the negative spin. Hence a wicked curve ball in baseball (the seams, and the slice in golf).

The Magnus effect was noticed by a german engineer who saw that canon balls would curve, based upon the canon they were shot from...A canon with a barrel slightly curved to the right would generate a ball shooting to the left. The flat line barrel does the same it puts back spin on the ball (back of the ball is spinning down), which causes lift on the top since the decreased air resistance, and in nature the one thing it hates is a vacuum, so air travels faster on that side and thus lift. The same thing happens when you break paint in your barrel...which ever side has more paint on it. Will cause the next ball to rotate and also pick-up some of that paint on its surface, now you have produced a curve ball. Until you clean out or shoot out the paint you will produce wicked shots, since each time you shoot you will change the distribution of the paint remaining in the barrel, thus who knows which way your next shot will go, until your barrel is clean.

That is what I figured. Thanks for the detail though. It is one thing to read the text in an academic format and totally different to have it explained from an author who is aware of its specific application.
