Dozer questions

[Lil Giants]

I have never seen any small scale dozers using grease for tension... coiled springs would be much cleaner & easier to incorporate.

While I realize using springs for track tension is the easy way to do a model, the grease adjustment on a 1:1 does not keep tension on the track, it only sets the clearance or "slop". Our model spring tensioners do zap some drive power by keeping the track tight all the time. I believe Joe's (dirtpusher9) Cat dozer uses a simple set screw lock to hold the track adjustment without a spring, and simulates the grease adjuster on the real machine.

Our model motors seem to have enough power to offset the extra needed to turn a chain while under tension, so I guess it's whatever you want to do.
