Cool! That's an impressive machine!
I was actually thinking about using 2x2 8t gears, but I don't have the room
in my model (And I've run out of racks too). Encouraging anyway, I'll do
some testing this weekend (and probably post a picture of the shattered
pinions....)

My model (link below) uses elevators with a double rack and double drive • axles (four z8 pinions).
I have tested it with a payload of 36lbs (more than enough for a complete • scale-size Saturn V).
By my calculations, thats 40N per elevator.  The rubber belt in the drive • slipped a bit, but the rest
of the gear train seemed to work without undue stress.  HTH.

Hi all,

I'm running into trouble with my mobile crane project. The boom is • pretty
heavy. I want to raise it with a rack/pinion, but I wonder how much • force
they can take? I reckon that for the first bit up the horizontal force • will
be around 50N. Does anyone ever measure how much a well braced double
rack/pinion (8t gears) can take?
