New AndyMark Shifters!

[VEN]

Hey Guys. I have a question. I won't post a new thread though.

Is this gearbox the same dimensions as the FRC gearbox in the previous years (2005, 2006) and we made longer shafts for our FRC gearboxes which mount the same as the stock ones. How are the main shafts on these gearboxes? How are they different, if different from the ones on the FRC one?

Thanks


oops, I just saw there are sprockets, I wonder how that can work with out setup.
edit #2: I get how to hook it up now, but my other questions still stand

THANKS

It's a smaller gearbox, but has the same gear ratios (12.75:1). You can run either a:

• FIRST kit CIM Motor (1 or 2)
• AM Planetary gearbox (1 or 2)
• or combination of above motors

The Output shafts on these gearboxes are the same as the old kit gearboxes (0.5" Keyed) and the only difference real you would notice as a user, is that it isn't a cast aluminum box which doesn't take as much space up.

Actually, the gear ratio is 12.75:1--and the output shafts are different (the old KOP unit was some metric figure close to, but not exactly, 5/8").

Yeah it is a cool design!

We came up with the same thing last year with our own modifications using the AndyMark transmissions. Servo shifting really helps with these transmissions.

Sorry Guys, I was talking abotu AM servo shifter GEN 2

I designed and built servo shifters for the trannys last year with a hack saw and a drill press. Andy offered to buy the design at the Wisconsin regional but it looks like he developed his own. My design was a direct replacement for the pneumatic cylinder which would require no changing of anything.

Very cool! Do you have any pictures or CAD files to look at?

as i said it was done with a hack saw and a drill press so CAD is out of the question and i didnt get any pics b4 it was torn apart so i can redo it for this year. ill try to get pics when its all done up with right since my team has real tools this year.

Have a look at what we did last year for mounting the AM shifters, we made plates to mount them right between two of the wheels in our 6-wheel setup. We are doing something a bit different this year, but this setup worked well for us. It was simple and used the kit frame.
