Dragline Crawler Build

Jim-that seems to work really good!! Your suspension looks a bit stiff to me though. Just my opinion but you have gone this far, I say put a 3rd. roller on the top just for looks if nothing else. The bottom looks much better to me but the top needs more. Great job either way!!Maybe you are tired of making little parts.

Awesome result on the tracks - simply, very realistic and they work a treat, with great scale operation. The chain drive was a good move - I think the o-ring drive set up would not have been able to transmit the sort of torque your unique track gear requires. I watched the digging vid too and was impressed - I wish I could find these sort of old retired workhorses over here in NZ to convert like this.
Nicely done I reckon and such a marvelous result without all the flashy gear.
Top marks!

Glenn,

Thank you very much! It is actually quite fun to dig and even more so now with the undercarriage !

The pulley and O rings was just my lazy initial test to see if it was actually gong to be a workable system, I already had the .25" steel roller chain, but the new plastic stuff became available and it is very easy to work with and seems up to the task. I also really like the fact that it should be a "weak" link in the system I case of over stress.
