I got the second sprocket finished, it looks like it's going to work pretty good
I started digging around in the shed and I found two old top link type of a deals? I think they go on a old disk / plow or something.
They have a forked end that the small sprockets fit right into, I cut these up and I'm going to use them for the track adjustments.
As you can see in the picture, the threaded end will slide into a pipe and then I can move the nut either way to change the length.
(I hope all of this makes since)
I was going to start on the frame today, but I found the adjusters, got excited and I started working on them instead .
I'm not going to have much time to work on this Sunday, but maybe I can get a little further along on Monday.
