Re: DeWalt Transmission questions

1) We had to use a 3-4 ft lever arm to remove the chuck from the rest of the gearbox. IIRC, we chucked up a large hex bolt, grabbed a wrench and a really long lever arm, and started turning. It eventually broke loose.
The chuck/gearbox shaft isn't threaded, correct? I attempted the long lever trick this morning, and broke a Craftsman ratchet. I'll have to try again with a regular wrench or a stronger ratchet.

we have used this with direct drive and we have been extremely happy with this system.
What size wheels are you using? Do you have any other gearing? What speed does this make the robot go?
We have thought about this, as it would elimate a lot of weight, as well as some of the problems with chain and sprockets.
