Re: Never Do This, and Other Good Ideas Gone Bad

Here is a list of 2791's don'ts with some explanations beneath it.

1. No Set screws
2. No Jags
3. Don't put non graded bolts in drive train.
4. Always account for force of pre-charged pistons
5. Don't put taps where they aren't 200% unavoidable

1. Set screws. We learned the hard way at FLR in '09, tightening the set screws before and after each match. Needless to say, by the time we hit Friday in Atlanta, every last set screw had been replaced with a cotter pin.

2. Jaguars. In '09 we blew at least 4 Jaguars, maybe even more if you count off-season work. Until we are convinced Jags are as tough as Vics, we won't put another one on our bot.

3. Never put any non graded bolts in a drive train. Every last bolt head sheared in '10 and took 3 hours to replace Saturday morning.

4. Never put a piston on your robot until you are sure it can handle the load. Last year every time our piston pre-charged, it bent our entire chassis. 15 lbs. of 8020 later, it still bent our entire chassis.

5. Taps. '10 was our first and maybe only experience with 8020, and we overkilled on the taps. It took forever to fix anything on our chassis, and by the end of the season, the screws had been put in and taken back out so many times the taps were loose.
