Re: Need help with the planetary drive on T-4XC


 

Gary,
My Plan A is to use a clamp just as you suggested, even if I need to fabricate one. However, after playing around with the vernier today I am not sure how to assemble it so it has the required preload. My initial thought results in a preload on the shafts, but not the bearings.I must be missing something really basic because this is not a complicated part.
Thanks for your help. I'll let you know how it turns?out. If I can't get it to work again, I like your idea of just not worrying about the vernier and directly couple the shafts.

Now I see..? the C-line is different from my A and B lines!

If it does depend on pre-load like you say, you just need a big clamp..? and remove the final cage and tubes.
My biggest clam is not big enough but you get the idea.

Or, nobody says you really need a vernier.? My early T-4X and the up to the early R-4A rigs didn't have them.
I even watched a YouTube recently that the guy bragged about the nice fast adjustment on his early rig!
Just freeze the two shafts somehow, maybe JB Weld or squeezing them?
