Pneumatic Gear Shifter

[AdamHeard]

I agree with other's comments that SSers are the way to go.

If you have to ask the general question of , "how do we do this", you won't be able to make your own for season reliably. And you'll certainly dump more money into that than just buying shifters.

SSers are awesome guys, after running them for a while you can analyze them and work on making your own.

The white papers here on CD have several shifting transmissions. Fairly simple designs by Andy Baker, Dave Lavery and myself were posted before the time when AM shifters were sold. All of these were competiton tested.

Search by tag "gearbox" . If you add the tag "frc716" you will find my 2005 dual motor, dual speed. It costs about $200 in parts and can be made with non cnc equipment.
