Duq,
I once had a 8t gear in rack & pinion lifter break on me - it was only a
single width rach, though. It was in a fair-ground ride I built (many years
ago). The arm it was lifting was pretty heavy, but I didn't actually weigh /
measure it. If you're worried, it might be worth using 16t gears.
Regards,
ROSCO

| 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. (...) (24 years ago, 16-Jan-01, to lugnet.build, lugnet.technic)
