Works fine for me here too. It is impressive, but it is also one of
the noisiest things I have seen in a while. One or two of those motors
sound like they are a little stretched.
Maybe it is encoded with a newer codec?

Most of the noise is coming from the ‘crowd’, the part that pushes the bucket
back and forth. It uses a bunch of 40, 24 and 8 tooth gears to do it’s
thing:

And they make a ton of noise, the gears. The motors there do not have
built-in
gear reduction, so i had to build my own transmission.

Cool. Could you get less noise and a reduction in space using a worm
gear? I seem to remember them being less efficient, but they would
give good reduction, and should lower the noise considerably, although
they may require placing motors perpendicular to the output shafts.

I probably could reduce bulk and noise by using worm gears, but at the time I
built that part of the machine I only owned two worms and I needed them in other
places. The ‘crowd’ has two motors and transmissions and I had already used one
worm gear in the bucket’s jaw..
However, I really like the noise. The machine is big, and the transmission
chattering helps give it an even “larger than life” feel. The hoist is even
better, it has four high-speed motors and transmissions inside of the house (the
red and white body part). Having all those motors and gears inside of a big
hollow space makes a really cool, deep noise that echos around inside and sounds
great. But you can’t hear that sound in the video, the upgraded hoist is new
and was in a different configuration at the time of the video’s filming.
On a different subject I have been starting a new project, a drilling rig. I
want to make something like this:
or an offshore oil drilling platform.
I really enjoy building models that are functional, so I want to make one that
can actually put holes in the ground and lay pipe. I have built a prototype
drilling attachment that I think will work, I will post pictures ASAP.

Any chance of videos of the upgraded hoist then? One other thing (...) (19 years ago, 1-Oct-05, to lugnet.technic)
