Hi Raymond. The Littlemachineshop info you are referencing is useless for building
an aluminum airplane. You need to listen to your peers. I repeat here my answer
to your same post on the 701/801 site.It's not that there's a downside to
running that fast. There's just no point to it. I've been a machinist all my
life (so far) and I'm 62 so picking a sheet metal airplane to build was a no
brainer. I've made the whole thing with regular cheap electric corded and cordless
drills. Please dont waste your money. A lot of the time you're going to want
to run the drill pretty slow anyway. Like for using reamers. 6000 rpm is for
machining aluminum in a CNC mill. To drill at 6000 rpm the drill needs to be
moving through the aluminum at 20 to 30 inches per minute. You can't do that.
You dont have the control. A machine does. At that speed it will drill through
a .025 sheet in .01 seconds. Id rather not have anything in my hand thats turning
at 6000 rpm. If you email me I'll give you a shopping list of cheap tools
for holemaking that will serve you well. Good luckGeoff     Lose this point
of view Raymond.

I forgot to mention. At 6000 rpm with just hand pressure, instead of making aluminum
chips you'll make dust. that will wear the drill out fast....Geoff
