Nylint michigan crane conversion, hopefully

[frizzen]

That's pretty much exactly what i had been thinking, i just didn't know how much force the machine uses vs the plastic strenght. I was trying to overcomplicate things.

I'm going to have to send you a pm, that's looking beautiful.

As long as you add a support rack for the off side I think it will work great, I only put two screws in the plastic horn. The screws are about 1/2" of from center so they will have all kinds of torque way out there and they only need to turn the drum. I have two of them made.

Here is the third one in the lathe, just about to drill the center hole.



Frizz, send me that PM. I can probably send these to you Thursday. I'm think I'll make the mounting bracket for the servos and the off side support as well.

Frizz,

Here are the three drums. I made a little angle bracket for them and decided to stop there and see what you think? They will need a strap across the opposite end of the servo mount tabs and I used a small 1/4" channel for the off end drum support. The center hole in the off end of the drums could be enlarged a bit at the end to match the head of a #6 cap screw which could be threaded into the channel to support the off side of the drums.

At this rate, you'll need to write up a dimensioned spec sheet on the parts or start offering kits.

Those are looking really great!

As far as i've found, real Clark Michigan cranes seem to be set up with a pair of dead lines off the tip to a sheeve block, cables run from the sheeves back to the house some unknown number of times for mechanical advantage and to reduce the amount of cable.





these are the most helpful images I've been able to find so far

Stock toy just had it route: fixed at house, tip pulley, cable drum. And it works fine as a toy.

Atleast for now, i'm thinking split the difference like jim did: fixed at house, tip, house, tip, house, drum.
