Re: WCP: 2017 Product Launch + MCC 2017

Ours are slightly different and include a counterbore to accept a portion of the shoulder bolts shoulder to eliminate the shear/bending force on the threads themselves (where the cross section is...

Re: Where to purchase wire?

They re-stock a lot of wire, components and tools with new inventory (not surplus).

Re: Team 254 Presents: Dropshot Technical Binder 2016

Glenn,

As Andrew explained, the mentors typically have very little involvement in the technical binder other than helping edit content towards the end. This has been the students project from its...

Re: Team 254 Presents: Dropshot Technical Binder 2016

Wheel hubs are custom, but very similar to the WCP ones. The obvious difference is that these are sized for the 8" pneumatic tires, and as such, have similar dimensions to the AM plastic hubs. Not...

Re: Team 254 Presents: Dropshot Technical Binder 2016

I think this is an error and we are in fact using 1.5" OD latex tubing as you are finding on McMaster.

Re: Open practice field in Nor Cal?

I was mistaken last night. We are hosting teams tonight with limited hours as Cory noted above.

Re: Spark Motor Controller vs. Victor SP

Agreed.

We are moving to the Talon SRX this year (ordered 20+ of them), but both the Victor and Talon are awesome WRT size. It allowed us to package a lot of electronics in an extremely small size...

Re: FRC pocketing

Re: pic: 3946 Gonfalon, V2

Are the logos intentionally grouped tightly together?

For many (most) logos, I recommend people search for that companies identity or brand standards/guidelines. Lots of good info about logo...

Re: pic: ABS-110, lightweight 2-speed PTO gearbox

Yes, it is. It is worth considering. We got away with it in 2010, but it was a little sketchy. Sometimes it wouldn't shift. We ended up having to shift to the other gear before shifting back to...

Re: pic: ABS-110, lightweight 2-speed PTO gearbox

This is correct. In 2010 we disengaged and in 2013 we did not. In 2013 the drive wheels were already off the ground so we had no need for the three position cylinder. When we were hanging, the...

Re: GameSense at Chezy Champs 2015

Recordings will be uploaded at 1080p/60 at ~20mbps. Live streaming at 1080p/60 is very bandwidth intensive and most users cannot take advantage of it.

Re: GameSense at Chezy Champs 2015!

Re: Tapped Holes vs Bolt an Nut

If doing what you have above with #10 or smaller screws, threads in the blocks will be more than...

Re: Tapped Holes vs Bolt an Nut

If you are trying to duplicate what we did on 254, I would heed Adam's advice and simplify things greatly. We make a lot of complicated parts seem easy because we do some unique 3D milling and...

Re: Team 254 Presents: 2015 FRC Code

We only used surgical tubing in 2014, as it gripped the ball better than the urethane and was way cheaper and came in thinner wall thicknesses. There is no rule for how much larger we go on tubing...

Re: Team 254 Presents: Deadlift Technical Binder 2015

These carriage bearing blocks were quite intricate, but essentially became the entire structure of the carriage. ...

Re: Team 254 Presents: Deadlift Technical Binder 2015

The pneumatic one worked fine for quals - where we used it to grab another can off the step with the lasso method seen at SVR. The geared version was shorter and not really designed for the same...

Re: RIP Banebot RS550

This. The performance of the RS550 never matches its data sheet. We stopped using the RS550 in the middle of 2014 when we had numerous 550s fry in our shooter (not really due to the lacking power)....
