|
|
Has anyone actually made a probe for an LRI ??
How do you drill the holes? Drilling the aluminum is a real pain. Not bad
until you get deep.
What type of drill is required?
The local machine shops have given me quotes that make actually make buying
the commercially available LRI cheaper!!
Any source available to buy a probe maybe???
Thanks in Advance for your help

The only way I know how to drill deep is by peck drilling. You let the drill cut a little then back it out to free the chips, use lots of fluid. Your drill press needs about 6" of spindle travel to do the AOA I saw on ch601.org. That also means your drill needs to be this long.
Or you might want to look up gun drilling. Thats a method where the coolant runs through the drill.

John, you ask for the "best" position for the probe and I really can't say, I can tell you though where I located mine and that it works well there. I located it directly behind the main spar, out board of the pitot tube. As such, when installed the end of the probe extends slightly ahead of the spar under the wing in clean air. Good luck, Bill of Georgia
