Jchannun,
It only took me two days to think of that!
Seems like you're gonna chip the flutes holding that mill?
Oh well, always a couple ways to skin a cat.

metal mite has the best idea yet, I think. Dunno why I didn't think of it -- I've done exactly that for end mills when I needed more "reach" to get into a tight place. Works fine. Only thing to watch out for is to get the hole for the end mill as concentric to the o.d. as you can, and as good a fit as you can.

Turn and bore (don't drill) it in one setup. Part off and then pretty it up. This will ensure concentricity.

Just make a sleeve for a larger endmill holder.
Any steel will do.
Pop a hole in it for the set screw and you're in business.

Yeah, no s**t!!!!
We ALL do that....like when we get a boring bar with a smaller shank than 1/2" and want to put it in a Criterion boring head.....

Brian, A allen wrench can make a boring bar. Cut short end way back and sharpen it. That gives you as small as 1/16 inch. Never used one that small but have used probably 1/8 inch
