Re: Dragline Crawler Build
looking good Jim ..quite a challenge and not your typical build ...your working through some pretty difficult challenges ..If you have a rotory table / Drill press you should be able to make your own spockets ..I did make my own for the Dozer.. A bit of math and you probably knew already though ...your circumference should match your pitch ..10 tooth x .25 pitch = 2.5 circumference
so diameter would be 2.5 divided 3.14 = .796 .Thats where you would drill your 10 holes
Overall sproket diameter would be bigger ..dont remember how many turns it took for one rotation of the RT but im sure you would figure it out from there..I did have to touch up a few of the teeth with a dremel though
I started out with with a 3x3 square .2 thick aluminum plate ..scroled the diameter of the circumference ..drilled the center and used a bolt and nut through the center hole to mount in the RT .Once the holes were drilled i cut out the sprockets with a band saw ..hope this helps you out a little
