How to put together cut to length pushrods

I have a lathe in work and I can buy correct size drill but I cant pay 80 bucks for one drill. I bet kids in china makes them for 5 bucks.

That tools says "bore .169" What that bore means? edit: does it means that the drill is tapered? from .157" to .169"?

If you have access to a lathe, then you ought to know you don't just grab a drill and use it to finish a hole to size. That is why comp sells the tool they do. Or, you REAM the hole. Never drill it.

Now that I have said that, it don't really matter in the end (no pun intended). The cup can actually just drop into the pushrod. Where is it going to go? It can't get out.

Still, there is a way to do things, and then there is the correct way. Either use the tool comp sends or use a reamer and do it correct.
