Best practice for tight BK12

[bluesking]

Thanks for your thoughts guys. I think sanding sounds like the way to go - making disassembly essentially impossible doesn't sound like fun.

Unfortunately my problem is occurring on the pulley end, not the floating end. I'm struggling to think of a way to support the rod so I can use a drill to turn it. I will probably just use a bit of elbow grease - I don't think this will introduce any serious inaccuracy into the machining.

I was hoping I wouldn't have this problem as I have bought good quality Chinese parts from a well respected supplier. They were machined specifically for me as well, not off the shelf. Shouldn't really have happened, but it doesn't seem like a big deal.
