Re: pic: Team 48 - Lock n' Load
That's impressive. What are you doing in terms of spring force? What's the weight of the ram? What's the starting gap between the ram and the ball (if any)?

The high power shot is selected by extending the 2 3" stroke cylinders, which adds 3" of pre-load onto the springs. The motor/gearbox pulls the springs back to firing position (roughly 6" of pullback). When the launcher fires, the majority of the stroke takes place with the ball in contact with the ram. The ram is 1" round igus aluminum rod with a McMaster 3/8" wide, 20 DP, 14.5 PA rack gear affixed. The rod slides through two open-top igus linear bearing pillow blocks. I actually don't know how much the ram weighs. The overall claw/launcher combo projects to weigh around 35 lbs. I was kinda thinking a .30 or .50 cal machine gun, but I think I like yours better. :-) |

Any reason for the tiny little pusher plate? Or are you going to replace this with something else? |

The igus linear bearings and aluminum shaft are also (literally) quite slick. Quote:

Hi Travis
How far are you hitting the ball? |
Re: pic: Team 48 - Lock n' Load
This looks like a really long shot but I'm assuming that the camera perspective affects it a bit. What is the maximum effective range of this launcher?
