What is out there for rethreading spindles?

[LonesomeTriZ]

I have some spindles that need some attention. I have a need for a rethreading kit that handles everything from a trailer to a D50 from end. I would also like to be able to do the spindles on my ATV’s. I have poked around a bit at some of the kits on the internet. But to be honest I am confused by what all I looked up. I do not know the sizes I require and without being able to compare the size of the tools in the photograph with what I need them for I have no way of know for sure what I am looking at. Can I please get some guidance on this subject matter?

hey, start with a metric caliper, since most of those are metric. or tell everyone here what it's for, and we'll get you some sizes.

Good idea. I will go out there later today and get photographs and measurments.
