Dragline Rebuild

[modelman]

Just a small update-I got the dragline back together and with this new swing motor I found the swing speed controller doesn't work. Now I have to sort out this problem and fix or replace things until it works. The flat wound resistor I am using on the controller is only 35-40 years old so I can't imagine why it would go bad. More later.

Would like to see all the details from your controls but maybe we covered that already. Shouldn't be a big deal to replace a resistor or two. I am getting ready to acquire some swing pedals for my machine. I will give an update when it happens.

Hi steve-Here is a couple of pictures of the hoist and swing control. The first one is the hoist which works good on the resistor set-up-

This is the swing control which I am rebuilding now-

I don't think it is a matter of replacing resistors. These cannot be found anymore. They were made for hi-performance car motors which turned hi RPM and drew lots of current. The swing motor I am now using only draws .125 ma. and I think that is why the resistor doesn't work-(not sure). Anyway I am reworking the swing portion and will post pictures as I go.
