Hood Shooter tips

So more squish then half a inch or less squish. I noticed others had more squish but they didnt have a hood lie the one we are doing.

More squish should still help with a hood shooter. Also more contact time with the wheel should help.

If you can take a picture of your prototype you might be able to get more help from people on CD.

I've linked the thread to the shooter team mentor. He should be able to give you details on what we have found and what we are planning with our shooter. The one in the video is our shooter from 2009 with a couple of modifications.

Steve,

To find the answers you seek, you need to do some experimentation. Vary the ball compression on your prototype and see what happens. Vary the speed of your wheel and see what happens. Use the data gathered in your testing in your final design.

We were talking about this. Would it be better to make sure the ball doesn't slip by changing the wheels to rougher and having the back plate rougher or changing the compression?

Here is a photo of our prototype. Looks a little messy but it works fairly well...
We tested with a CIM motor but we are using a Cim-Sim in actuality.

Thats a solid working model for testing. Take some material and add it to the inside of the hood to increase the compression, many teams have found success with ~1.5" of compression.

Another option you guys have is to change the ratio between the CIM and the shooter axle.

Testing is really the only way to see how your setup works. Have fun and remember to watch for damage to the balls.

You can also try covering up the holes in the wheel. It will decrease the drag on the wheels and add more mass to the wheels.
