Default Re: Dragline Crawler Build

I am planning to drive the crawler with chain and sprockets like a full scale. I am thinking about ordering some of this .1227" plastic chain but it says 14lbs tensile strength. Is that is way to weak! I don't have a good feel for that in this application.

Is it okay to post a link like this or is that a no-no?


I already have some .25 inch stuff, but I haven't found sprockets small enough yet. I'm gona need about 7/8" for the large sprocket at the tumbler and something smaller at the motor.

Stephan, I get a bit out of the process too. The other day I was about to make some more little tabs that rivet into the pads. I was starting to clamp them into the mill vise and remembered that I had that little fixture block. I went to my thread just to recall the size and shape of the block to make it easier to find in my pile of stuff!
