Re: WCP: 2017 Product Launch + MCC 2017
 

As a heads up, the rollers page under How To has updated images of example rollers. I'll have example roller configuration CAD uploaded today along side the complete User Guide/Design Manual.

So just wondering, what would be the suggested way to mount those inverse shifters?
As in, where on them would you recommend to attach to?

Re: WCP: 2017 Product Launch + MCC 2017
 

Looks like it goes where a normal DS would go, like straight onto a 2x1.

Re: WCP: 2017 Product Launch + MCC 2017
 

Was wondering about the ways to use that for Sheet Metal frames.
Seems like it doesn't quite fit, and is more suitable for tubes. Just wanted to make sure...

Re: WCP: 2017 Product Launch + MCC 2017
 

The WCD version with either versablocks or WCD Bearing blocks straight to a piece of 2x1. The non WCD version would be mounted to the 2nd plate and have cutouts for the CIMs. Again I'll have pictures and manual up. Working on getting the roller one up first then the gearbox guy.

Attached a quick image, but we will have 4 different configurations for WCD that show a setup for #25/#35 chain with VersaBlocks & WCP Bearing Blocks.

Please let me know if the above helps.

For sheet metal frames, I can help integrate it if you can send me the CAD file of an example your working on.

Please email support@wcproducts.net

Thanks!

I dont really have anything specific, but the basic idea would be something like 1114's guide to Sheet Metal.

around 1:25.

Re: WCP: 2017 Product Launch + MCC 2017
 

We will try and work towards getting some resources out for non WCD specific stuff, no guarantees.

Also CAD Files of examples + User Guide is up for the Rollers!

Re: WCP: 2017 Product Launch + MCC 2017
 

We would really rather not have our wires going out above our 2x1, so I switched the output side when I assembled the flipped gearbox in Solidworks. With this configuration, would we need to still order the WCD add-on kit? Also is the length of the shifter rod different between the WCD and non-WCD? We would like to have the pancake on the inside of the robot, on the backplate of the gearbox.

Re: WCP: 2017 Product Launch + MCC 2017
 

I am a little puzzled about what you are trying to achieve by using a flipped CIM gearbox. It seems like a lot of unnecessary weight/ complexity if you aren't actually going to have it over the wheels. Also having the wires going out the back of the CIM's isn't a problem when bumpers are used( ie this season).

Maybe the normal WCP DS could be a better fit for what you are trying to do.

Yes, you will still need to order the larger WCD variant. Another thing, your sprocket looks like it is a long way from your bearing block. Removing some of that spacer and moving it closer to the bearing block will be beneficial.

Also apart from the awesome new product line up, the new CAD videos in the resources section are super helpful and well worth watching if you have time before kickoff( or even after for reference) Andrew does an excellent job of explaining the nuances and tips and tricks of belt/mechanism design in SW.

Thanks to West Coast Products for these new resources.

We used the normoal WCP DS last year, and our biggest problem was how much space was taken up with how long in extended into the interior, and we had problems with our pancakes and were not able to access them easily.
In response to your comment on the sprocket, I'm working on it. At 1/4" spacer, the chain would not fit between the sprocket on the output axle and the dog gear above it. Picture has 1/2" spacer in use, will probably change to 1/4"+1/8".

Re: WCP: 2017 Product Launch + MCC 2017
 

Excellent guide, thanks RC!!

Now, can you do the same for the Flipped Gearbox?? :D

Re: WCP: 2017 Product Launch + MCC 2017
 

Out of curiosity, why don't you want to run wires out above your 2x1? We ran almost this exact same setup this past year on 1323, and it worked amazingly for us with no issues. We just zip tied our wires to our motors and ran them back inside the robot without issue.

What were the dimensions of your drivetrain? I can fit a WCD DS in WCD configuration into near every WCD I've designed with ease. In most cases, I'd argue that if you can't fit two DS's in your drivetrain, your drivetrain may be too thin to fit everything you need for your robot.

Re: WCP: 2017 Product Launch + MCC 2017
 

Whoa buddy, chill out. He didn't say it didn't fit, he said there were tight spaces.

We had to make sure our gearboxes were at the back of the 'bot last year to be able to fit a ball path at the front for the game piece... and I'm very glad that we never had problems with our pancakes, because we needed the smallest hands on the team to get to some of the electronics packed in there under our CIMs.
Getting 2-3 more inches in the middle of the 'bot with unconventional use of this design seems well worth exploring...
