I'm needing something to make some simple parts beyond the Mach Wizards, but can't really justify spending lots of money just now (holiday and shiny bike bits have drained funds!)

I've got plenty options for creating DXFs, so that's not an issue, but converting them to G-code is.

Looking at what I'd like to make just now, I could probably just about get away with writing the g-code (mostly a mix of centre holes, tapers, and reduced sections)

So what are the options?
Manual G-code?
But how does that work for doing multipass tapers/reduced sections?
Cut and paste the various Mach wizards together?

Simple CAM?
I've already tried Lazyturn, but the lack of finishing pass puts me of.
I see mention of CamBam, but they've only recently added a turn module.
Any others suggestions?
