I was one of the top students on my team, and my life pretty much only consisted of...

Re: Presses and techniques for 1/2" HEX broaches
On 100 I used to center whatever I wanted broached on the lathe, and run the broach through it using the tailstock. You were pretty much guaranteed that the broach would be centered and perpendicular...

Re: Bearings vs Bearing Blocks
100 ratcheted in 2012 when we were climbing the bridge. 6" wheels with 16T sprockets. There were more than a few stupid things going on with that drive, but chain alignment wasn't one of them. The...

Re: Bearings vs Bearing Blocks
I think I confused you on cause and effect. Ratcheting is caused by loose chain, which is a consequence of chain stretch, wear, etc. Chain-in-tube drives help alleviate some of the symptoms of poorly...

Re: Bearings vs Bearing Blocks
I have yet to see any really good explanations of chain stretch. That doesn't mean no one understands it (if someone does, please jump in!), but that for the most part the FRC community is interested...

My personal experience with c-c designs is limited, and a lot of the info I have is from talking to friends on other teams.

Re: Bearings vs Bearing Blocks
If you're talking about VersaBlock style, then yes. We ran .0625" drive frames in 2013 and 2014 (and that was Arial Assault!) with that type of wheel truck.

Re: Bearings vs Bearing Blocks
Tensioning is the primary reason for using bearing blocks (or wheel trucks, or whatever you want to call them). There are a number of ways to tension your chain/belt/whatever in your drivetrain, but...

Re: Team 254 Presents: 2015 FRC Code
Not on 254, and it's been a few years, but when we build in intake with BBD in the 2013 offseason, we bought 1/2" ID tubing to go over 1/2" VP hex. There was plenty of interference, and it wasn't...
