jwatte, nothing gives that warm&fuzzy feeling like good visibility.Quote:
seeing where you go is important :-)
While I couldn't use the ballscrews I have available for the lifting of the bucket(too slow, small pitch)
they may work out best for the dumping(only 10" travel)
looking for a 4 sec. dump time(2 sec. down, 2 sec. back up)
smooth!

with all the effort & costs that went into making the lifting frame, I'm going
to install a second prox switch on each end of travel, that shuts down drive
and turns on the brake.
or the sabertooth drive has a current limiting pot, while it can lift 500lb+
there's no reason to for snow. maybe just adjusting to a point where it
can't damage the frame would be best?
That looks awesome!
You probably should do both current limiting and safety limit switches.
Not sure about the plan A for dumping.
the gear motor I plan to use has a 180rpm output, and the sprocket on the buckets
only turns 90deg. to make it at least reasonable if things go sideways, I got 9 teeth
on the motor 45 teeth on the dump shaft, then 12 teeth on the dump shaft output to
the buckets 36 teeth sprocket, which should give it a 8 to 1 gear reduction.

hope to test the dumping setup this week(waiting on motor with brake)

to set the height of the blade I had these welded on($25.00 sweet!)
for small casters and a orange plow marker flag(should show up on camera).

I'm going to one more shaft, 12 teeth and 45 teeth get a slower
speed on the dumping setup.

I was able to test the dumping drive setup.
the speed is manageable but, even with a 1" shaft because of
the amount it's unsupported on each end it acts like a leaf spring(crap).

Looks quite robust! Now all you need is another foot of snow ;-)
