I'm glad to see your progress
But this episode has me question a few things ....
1) We all know that a Drill-Bit can NOT drill a Round nor Straight Hole !!!!
2) a Reamer can't correct the Errors from #1
3) if a Straight Round Hole is needed - you will have to Bore it, with either a Boring Tool or a D-Bit.
3) a Reamer Needs to Cut => 0.2-0.5mm. for a Hole around 6mm. - so why do you only Cut 0.05mm. ?
Or that is what I would have answered anybody asking me on how to do it .... have I got something wrong ?
Best wishes
