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.
