Looks good, nice and clean… those wheels though… they look like they might rip the ball up.
Are the Flywheels actually mounted that high? We’ve found that mounting them in the exact center works best.
If you sand down the edges of the wheel, they work great. Just spin them up on the shooter, and hold a piece of sandpaper up to them.
Looks like a nice simple way to score. Easy to build. Doesn’t take up too much space. Looks easy enough to tweek and make a consistent shot out of it.
Nice job
Looks awesome guys! Great work!
Just a heads up. Those aren’t fly wheels.
fly·wheel
noun
a heavy revolving wheel in a machine that is used to increase the machine’s momentum and thereby provide greater stability or a reserve of available power during interruptions in the delivery of power to the machine.
Just so I understand, the “flywheel” part of a shooter would be the extra weight added and not the actual firing wheels themselves? While these wheels are not flywheels, is it safe to say that heavy shooting wheels are technically flywheels in their own right?
Yeah, I guess a heavy shooter wheel would be a flywheel in itself.
We updated it and put a small spacer. Making it slightly lower on the ball.
Can you please provide me with a threshold for when a spinning object is considered “heavy”?
When it’s a flywheel.
A flywheel does not have to be heavy, to be able to store energy/momentum. The speed of rotation is also important as well.
Just look at Formula 1 Racing Flywheel System. They use 240 mm diameter flywheel which weighs 5 kg and spins at around 64,500 rpm. They can store enough energy to give a power boost of 60 kW for 6.67 seconds.

I can see both sides of this argument. In general when I think of a flywheel I think of something that stores energy and/or dampens. Personally I would not consider a shooter wheel a flywheel but I have no problem with those who choose to do so.
At least it’s not a piston 
Yeah, I was attempting to indirectly point out that you can’t say a wheel is, or isn’t, a flywheel based on its weight. Because whether or not it’s “heavy” just depends on how much energy you need to store.
I just wanted to emphasize the fact that the OP’s terminology was correct and that these are considered flywheels in this application.
But they’re not, these wheels are not storing energy (or at least enough energy to make any difference) which is the exact point of a flywheel.
That’s a flywheel!
Yes they are. They’re storing kinetic energy. If the wheel needs to be spun up before the ball contacts it for it to work as intended, then the wheel is a flywheel. Whether or not it is a particularly good flywheel isn’t relevant. Spinning wheel shooters in FRC work by storing kinetic energy, which is exactly what a flywheel is.
It is still a flywheel, just not a particularly good one.
It’s definitely a fly wheel but not in the traditional sense. We spin the wheels up for a couple of seconds to gain energy before the ball is pushed into the wheel therefore it is a fly wheel.
