For all of you who dont know what we are using drills for, we are taking 6 DeWalt Drills and taking them apart for the transmissions. We then use them by attatching CIM's or Fisher Price motors to them and having servos change the drill speed on the transmissions. ITS SO COOL. Works great. We used the last year but DeWalt re modeled the drills so we had to make some changes.

you guys should ebay off some of the spare parts i bet there money in like the motor and chuck

Can't you just purchase the transmission from the dewalt service department rather than purchasing whole drills?

How many are there? Purchasing 4 of those drills at $250 a pop = $1k.

The XRP transmissions are good, as many who have used the recipe given in this famous CD whitepaper (my own team included) can attest.

But it appears you are tossing out some good plastic parts, or maybe in your haste to get at the transmissions you destroyed plastic parts that might have stayed useful. I've built very handy things using those plastic parts. For example, the plastic handle, with the electronic trigger and battery connector that it houses, can be used to make a nice little motor tester.

i almost cried when i first saw this

i think we tried getting just the transmissions but we didn't have any luck finding any but we are considering selling of the undamaged parts. The handels had to go b/c we cut them strait of so we have the plastic and metal cassing around thr transmission. We also had to cut a bit off the back of the drill. The motors, triggers , torque setting dial, and the large metal front where the bit would go are all in perfect condition. We have to reverse thread some small 9 thooth sprockets to srew on to the exsisting axle. But we were also able to use all three of the power settings so we now have a 3 speed drive train

Also, the drills were cheaper then the ones u buy in the store b/c we didnt need to buy the batteries and chargers.

we (team 418) had to go and buy the older version of the Dewalt XRP drills to get the trannies we had specs for. what changes did you make to the CIM mount to get them to work with the new model XRP? we are set for this year but next year there wont be any any of the old model left!

Mabey we can talk at LSR too!

[tacopaco789]

Well im gona look more into it but only needed to change the servo mounting braket b/c the drill cassing is larger then before. We machine our own sun gear adaptor plate that goes right on the sun gear that lets th cim attatch right to it

Note that the outside is not reverse-threaded. It's the inside of the output shaft which has the left-hand threads.

Good job guys, we did the exact same thing

[Richard McClellan]

We are doing the same thing This will be our first year using Dewalts on the competition robot, but I did personally assemble 4 CIM/Dewalts (DC980) for an off season project last year. We have 4 DC940's that should arrive Monday, but I was hoping to get a head start on making some of the parts (top hat, servo plate, piano wire piece, and CIM mount). How different is the new model? Could anyone post or PM me dimensions or changes that need to be made in order to work with the new model so our team could get started this weekend?

For all you folks looking for just the transmission, check here:

thats amazing. we tried ordering just the transmission from the componie but it would have endded up being more expensice then the entrie drill b/c we would also need some of the other parts. But we will def use this from now on. Thanks again
