Hey Richard, in a T-handle, not drill at all...no heat, lots of control. I'm getting the CF tool to experiment.

I read your post rightly,, grin.. I think anyways.... I wasnt refering to the use of any "cutting tool" as I didnt really see that as your point. My point is that I feel its best to use a Tool like the Yamaha tool, and go in from the top. If I read your posting correctly what you do is essentially to use a tool that has a uniform diameter its whole length, and "size" the hole to that diameter from the bottom of the key. Sounds good... probably works well enough.. and I used to do it this way myself (tho not with the smooth end of a drill bit.) I just found that doing it from the top with a contoured tool is the fastest and most consistant way to do it. A little sideways rocking from the top side doesnt do as much...er.... "damage" (if you get my meaning) as it does from the bottom, and I found that it was much easier to over-do it from the bottom. I assume you turn the drill on... so as to turn the smooth end of the bit... how fast does this go ?? and how much heat does that generate ?? In the end tho.... whatever works.....well... works.
