Andymark just dropped the new EVO Shifter gearbox. Link here: http://www.andymark.com/EVO-s/643.htm

Thoughts?

I think you should've included a picture.

[Lil' Lavery]

Hurray for including a keyed output shaft option!

[Ari423]

Don't think this could have come out any later

This looks like a great one-stop solution for most all shifting drivetrains. So grateful for all the great new COTS drive gearboxes this year. Looking forward to inevitably using this considering how many options it provides.

So did I interpret this correctly?

13) Using existing mounting plate holes, it can be mounted to an AM14U family chassis or a 2"x1" box tube frame.

It's a drop in for the kit of parts chassis?

Hey Billfred, how are you manufacturing the plates if I can ask that?

I am assuming this teaser was for these gearboxes: https://www.youtube.com/watch?v=I96uKAjS7k4

52 of those stupid CNC's and all I get to use them for is making cyclinder heads.

Looks very tough. All steel gears. Big ratio on the first stage, with a 32 DP bull gear and press-fit pinions. Compatibility with the AM14U chassis is a very big deal.

All the design trades indicate classic AM thinking: robustness is worth a little weight. About a pound heavier than a DS -- but this will be a good trade for many teams.

I only wish the release had coincided with my team's Summer/Fall projects.

I hope they have paid special attention to the dog gear. I'm glad they've redesigned it. We had numerous pin-shears and tooth roundings on PTO using the old style stainless dog. Upgrading it to tool steel and making the teeth significantly wider helped substantially.

Speaking as a mentor of a team where a hundredth of an inch is a theory, WOW! Two pounds more than somebody's custom shifting gearbox is barely noise. Once we figured out that 80-20 was for prototypes and not competition robots, and that steel was only for fasteners and actuators, weight hasn't been a serious issue for us. If shifting is needed for our strategy this year, this will be way high up the list.

Might want to move it down the list. It's already out of stock.

[Nathan Streeter]

I haven't opened up the CAD and checked out the details, but I love the big reductions available in a two stage gearbox along with a lot of other flexibility (2vs3 CIMs, encoder options, output shaft options, etc). Reasonably low weight and stock spring-actuated pneumatic cylinder is very nice!

I never saw it in stock as it built to order

I can say this now without incurring the wrath of Kate Pilotte: Yes, the EVO Shifter is designed to bolt right up to the AM14U3 which is the 2017 Kit of Parts drive system.

Ding ding ding!

Commander Canada was also holding the new dog, with blanks of the plates behind him and an incompletely-machined one on his neck.
