The other night, I started exploring what uses can be made of the big gear wheel
from the Hailfire Droid. Having plenty of ZNAP beams handy, I used a few of them
as a gear box to hold the wheel.
The first attempt was to use four 8-tooth gears, in the next pin hole out from
the center. That worked, but there appears to be an issue with the
inside-curvature of the big droid wheel (an inverted gear as I think of it) and
the tight turning radius of the 8-tooth gears. Much chattering of the gear teeth
was heard. So I switched up to 40-tooth gears (as shown above). Very smooth
action now... and quiet ! Someone in another thread remarked that the droid
wheel could have used some pin-holes (for securing to an object).. I concur on
that.
Onward to practical uses ! (like using it to drive my ferris wheel)

I've been thinking, there's gotta be some way one could adapt one or two of
those hailfire droid wheels for a turntable assembly, like for a crane
project or to build a rotating restaurant on top of. Anyone got any ideas
or photos that might help?
Cheers ...

Several people have already done it, here's just one example:

That's what a power drill is for. :)
Excuse me for a moment while I prepare for the inevitable onslaught. :)

Version 2: now I have hard points on one side to attach it to something... and I
have complete clearance on the edge on the wheel...
The two halves are held together with eight p/n 32207 ( apparently a ZNAP
connector ) and four regular technic pins with friction ( which are hidden
within the ZNAP connectors ).
If I wanted to use up 16 of the 40-tooth gears and four of the big hailfire
wheels, I could have the beginnings of a vehicle here (mega-scale of course).
