Well it’s been a while since I put up a post I’m one of those people where if I’m doing customers jobs I make sure I don’t get side tracked .
It’s been flat out due to Rocky Nats builds , boxes not holding up to the punishment some due to being standard 40yr old boxes and some due to builders telling the owner more has been done to the internals then actually has been done .
My latest build just goes to show how hard it is to find a good C4 and how you don’t give up no matter how bad they are inside , it’s a lot of work but it’s a good feeling saving them from becoming parts boxes .

Building another 4 pinion planetary for a upgraded C4 build ( no Chinese parts used ) .
I’d rather get them in kit form that way I know it’s been put together correctly.
With 18 little rollers per gear it’s so easy for mistakes to happen

First part of one of my rebuilds is taking the alloy housing back to clean bare alloy before applying the paint .
