By the way, we had to remove our compressor, too. It sure is harder, but we get by.



I agree, there is nothing wrong with using aluminum sprockets as long as there are enough teeth engaged (i.e. big enough and enough chain wrap). Our arm has a 60 tooth hubless aluminum sprocket that we got from a snowmobile parts distributor out in California. We even drilled holes in that! If has got to be the coolest thing on our robot.

Swiss cheeze it is, BTW all of our sprockes have a 180 deg wrap, Was trying to not have one wheel chain fail kill the whole side of the bot. Hope to get the aluminum done and make the Kettering event in the fall, use this as a recrutment tool to get more students on the team and give them a pre main event experiance.
