How well do those small cylinders lift the ball? They just look a bit punnie in comparison to the 2'' monsters on the launcher. We tried one 1.5'' by 10'' cylinder mounted in the center ( with mixed results).

looks exactly like our bot except we can't lanch

hipsterjr · #5 14-02-2008, 22:27

I think you mean 1726. 342 also took this approach, but we are waiting for our shiny decals before we post pics.

Question: We all seem to be using pneumatics for our forks to pick up the ball. We tried to use one 1.5" piston in the center, but we are having a hard time finding the right geometry. Any tips?

MrForbes · #6 14-02-2008, 22:30

yeah, put the cylinder on the side! and leave as much room as possible for the ball

We've got a 1.5" bore, 8" stroke moving the lifter; works beautifully. Here's a fairly crummy picture of the geometry we're using, hopefully it helps. Good luck!

were using tiny pistons, they work great for us. Unfortunately i can not share their sizes or angles

MrForbes · #9 14-02-2008, 23:00

Yeah, having two small bore pistons would be the best way to go, so you don't have to deal with all that torque trying to tear the lifting arm apart.

falconmaster · #10 14-02-2008, 23:12

Is the torque why you are using the ABS tube on your lifter for? To min the effect of the torque?

MrForbes · #11 14-02-2008, 23:20

That's right.

Hmmm....there are 3 twins in my household: me, and my twin sons.

Maybe it's like that?

D_Price · #15 15-02-2008, 10:37
