WCP SS Gearbox dual CIM?
 

http://www.wcproducts.net/wcp-ss-gearbox

From what I've seen, there is absolutely no option to order this gearbox in a dual CIM version. Am I missing something?

If I'm not missing something, is there a way to convert it to dual CIM without the extra piece of the motor plate sticking up on top where the third CIM would have been mounting?

We were just planning on chopping the top off. The spacers are all below the level of the third CIM mount anyway.

If you email me here, we can put 2 - 2 motor plates instead of a 2 & 3 motor plate in the gearbox package. *A little backlogged on emails but will get back to you by the end of the weekend.

Thank you!! We have a meeting tomorrow to discuss final drivetrain choices, gearboxes included. If we decide to go the WCD route, I (or someone from our team) will shoot you an email :)

It's a great product, happy with ours. I'm printing/testing an encoder mount for CTR encoder, if that helps will post later today.

I would leave the 3rd cim if you can make it fit. You never know.....

We've decided against 6 CIM because it draws too much power and we've never needed it.

If you could post that encoder mount that would be awesome! My team is skeptical about the encoder in axle style mount because of the way it's held down by the encoder wire.

I'm looking at the cad for the WCP SS gearbox, if you look on the back of the gearbox underneath the motors where the pancake piston would be if the gearbox were a DS model, you'll notice that there's a 1/4" hole in the back of the drive axle (if you haven't replaced it). There are also two holes flanking the drive axle. My thoughts on an encoder mount would be to 3D print some type of bracket to bolt into those flanking holes, and then have a face plate that the CTR encoder can bolt into. Keep in mind that the encoder shouldn't be loose, but the mount should have enough flex so that when the gearbox is under a normal amount of stress, the encoder isn't forced to also endure that stress and can move slightly.

You don't have to hold the encoder still by ziptying the wires. They come with threads on the front face and a nut, so you just need to make a plate with a 3/8" hole in it to shove the encoder into, and 2 smaller holes to mount onto the two holes on the WCP gearbox. Same as CTRE encoder mounting you described, only with a 3/8" hole in the middle.

We used the mounting holes for the topmost CIMs to mount support bars (the 5/8" igus beams that are in the KOP each year) that span our chassis. We then 3D printed mounts for our speed controllers that are attached to the support beams.
