Toughbox Assembly

[Coach Norm]

Is any team going to mount their Toughboxes with the KOP chassis turned upside down? We are considering this option to get lower to the ground for lower center of gravity. I have looked thru the post but cannot find any information concerning this option. We are a Rookie team and will take any advice. We are concerned about removing parts of the chassis and losing the integrity and strength of the chassis.

We have difficulty with the roll pins. We went thru all four and had to go to Harbor Freight to buy new ones. They are put together now and we ran a practice test this past weekend on the KOP chassis.

How loud are these supposed to be while running?

While I don't expect everything to be "whisper quiet" one of our more experienced mechanical mentors noted how loud it was while under power with a single CIM, and commented that things may be pressing against each other making things louder than they "should be" from his experience.

Then again, I'm sure the sound resonance of making one gearbox side out of a lexan type material also turned the normal noise from it running it into a speaker box pretty much. (As opposed to it being made out of cast aluminum or some other cast type material that is better at sound and vibration dampening).

We're certainly not going to be taking a decibel meter to the gearbox, but just wondering how loud it should be???

You apparently didn't get the "joy" () of using the Banebots last year then did you? The pins were too small and just fell out under normal conditions...
That sucked... repeatedly over the course of the season, for many many teams.

We had 4 BaneBots gearboxes last year. Assembly was a breeze, and we never had to touch them once after mounting. They went through the whole season of competition and PARCX without a single problem.

I heard some teams had problems with them, I guess we just got lucky then.

I'm there with you. Every time we turn the SIMS on while attached to the Toughbox, I stop in my tracks. They sound terrible and I keep saying that something just isn't right. Last night I commented that I hope they have a lot of extras at the competitions.

NEVER use epoxy to hold the bearings in, that may seep into the bearing and cease it.
