Nylint michigan crane conversion, hopefully

SteinHDan, that would work too. I was just planning on running the gearmotor/esc combo units like i'd seen on other cable machines like built by thestuff, smallhaul, rvjimd

Truckmaker, yeah you're right what can i say... i suck at building and having time/money.

I know the longer boom will impart a lot more moment on the machine, i just wanted to see how things change around, and more reach looks really cool. I'm also not above running lead ballast if it needs it.

jim, i greatly appriceate that.
I was thinking something maybe built off one of these:

Thinking i can have a protrusion to index to the .500 hole and a flange to bolt on the near-side. i wasn't sure if it's worth it to have far-side support on the drums?

I need to break out calipers and think and mock up a bit before i'd be able to do a dimentional sketch for your consideration.

Or depending on the alloy you have, i might be able to just order a spare gearset and just broach the splines into a much simpler drum instead of getting that crazy.

Frizz, do you have the servos already? If not, I highly recommend the hitec 645MG. Especially since I have some of them here already and I can use the round horn to make up a prototype drum.

I would do some off side support, it isn't too much more work and helps support and align the drums.

I'll do something on this today and see what I come up with. I am going to see if I can simply use one of the plastic horns that they come with. I don't think we need the metal spline version for strength. I'll post my progress here.

How about like this? I'm about to drill the horn to the drum. Then it can be screwed to the servo through the center hole in the drum. The off side can then use a pin to support it.
