krv300 thanks,( sorry I don't know your name?) I do like the idea of machining a mt3 down to a mt2 so I can fit a extension piece, i may "practice" on a old bit lol
has anybody done it?
Jonny ,quill travel is about 150 mm if I remember, its a good drill. in fact i bought it specifically for this job, i got it from a dealer who in turn had bought it from a school where it had sat for years in a "sewing room" the room once being a tech room, but i guess wood /metal working skills aren't taught much now?

so it hasn't seen much action,
I've had a few answers on YouTube and they seem to be leaning towards line boring
I like the idea of offsetting the bull nose cutter, i didn't know that,
