Help with drill-Mill conversion

[irving2008]

Finally got some workshop time this evening and finished setting up the lathe. :dance:

Spent 30mins centering the quill in the 4 jaw chuck. What a nightmare!think Ive got it sorted now. (when I realised that 0.001" run out is F**k all) Ive drilled out the knockout slot to 10mm and created a start point for the tap drill.

The hole through the ER chuck is about 9mm , so the max bolt size I can use is M8, Problem is getting a drill bit and Tap that will reach the 150mm
required.......

Any one know of a source of long reach taps? or will i have to make up some sort of extension bar?

Let me get this right... you're drilling out the quill to allow a draw bar through to pull the ER collet chuck into the quill... so what are you planning to tap? did I miss something?
