Re: Unit Cable Hoe
Well, I pulled this project back out and started working on it again. I am hoping to make the National Pike show and would like to have this finished for it (May 21st). The chain drive works nice and has plenty of power. It is going to be cool to get the chain rotate setup, it should work smoothly.
Here is a video of it working: http://www.youtube.com/watch?v=ft1fAnn2sIA

Re: Unit Cable Hoe
Scott. The car body works very nice. When the upper is on there and you have cleats you should be able to go anywhere. I'm surprised at the power the servos have.

Re: Unit Cable Hoe
Thanks Rob, I am a little surprised my self at how much power it has. I also dragged a 10 pound steel weight with it and it pulled it just fine.

Re: Unit Cable Hoe
That's a cool little robot in it's self. That won't have any trouble traveling up a pile of dirt. Definitely the "High Walker" version. You'll be able to do pipeline up mountains!

Re: Unit Cable Hoe
What a neat project!
ServoCity are great, I use their adapters, too. Haven't had a chance to check their chain - good idea. I assume this is the plastic chain here: http://www.servocity.com/html/chain.html |

I couldn't get their servo splined sprockets to work though. They were very helpful trying to help me (GREAT customer support) but, every sprocket they sent me grabbed the chain badly. The only way there sprockets would work smoothly is if the chain only wraps around a small portion of the sprocket. I said to them "simply wrap the chain around the sprocket and you will see that it is STUCK on there" and they just ignore the comment... the standard $3 sprockets I ordered from a discount chain work fine.

Re: Unit Cable Hoe
Ah, sorry, I was confused! Need to learn to read
Their plastic chain has a spacing of 0.1227, so I thought you meant this. """" Turns out the #25 chain I am using has a smaller roller diameter (.120) than they use (.127) which would explain why my chain binds up when you wrap it around more than 100 degrees or so. They are sending me some of there #25 chain to rectify this. """" But what you wrote is that it's the diameter of the rollers that is different. Never heard that before. However, using a chain with smaller roller diameter on a sprocket designed for a larger diameter should work, I would guess. (Never tried it, though.) Thanks for the heads-up, will have to remember this... |

Re: Unit Cable Hoe
Got a little more done. The chain drive for the rotates is finished. I maybe over engineered it but, I wanted it to be strong so that I could push dirt sideways with the bucket on occasion and not worry about anything breaking.

Re: Unit Cable Hoe
This may be a silly question but what are the black wire leads going into the track frames? Are the drive batteries between the rails?
It sure works well on rotation and looks to have a good speed on the tracks |

Thanks Neil, haven't worked on a new boom yet. It will probably be a while until I get to it. Once the weather turns nice I don't spend much time working in the basement.

Re: Unit Cable Hoe
Nice work Scott. I see you went to chain drive on the slewing ring. How come you didn't go with a gear like your dragline?

Re: Unit Cable Hoe
Thanks Steve. When running the cable hoe you can run the side of the bucket into a truck or dirt pile and put a lot of stress on the rotate mechanism so, I wanted it to be very strong and reliable. The setup on the dragline works great but, it only has to move the boom back and forth and never gets struck or jolted hard.

Re: Unit Cable Hoe
Hey Scott. I thought that maybe those wires were for track heaters, so you could work in the snow.
